ABSTRACT


BACKGROUND Cerebral ischemia and hemorrhages were reported to be the main complications of polycythemia vera (PV). The relationship between PV and increased risk of the cerebrovascular events has been established. Some patients with secondary polycythemia have thromboembolic events comparable to those of PV. However, secondary polycythemia that leads to cerebrovascular events is uncommon. CASE REPORT A 35-year-old man without any prior medical history presented with mild clinical acute ischemic stroke and polycythemia. The patient then showed worsening neurological deficits that were later attributed to the concurrent cerebral venous thrombosis, which led to malignant cerebral infarction with hemorrhagic transformation, and subarachnoid hemorrhage. His polycythemia appeared to be secondary to bacterial infection. The treatments for the secondary polycythemia were first phlebotomy and intravenous hydration, followed by intravenous broad-spectrum antibiotics. PV was excluded because the JAK2 V617F mutation was absent, the patient's peripheral blood smear suggested secondary polycythemia due to bacterial infection, and there were improvements in hemoglobin, erythrocyte count, and hematocrit after intravenous antibiotics. At the 1-month follow-up, he was moderately dependent, and hemoglobin, erythrocyte count, and hematocrit were within normal limits, without receiving any further phlebotomy or cytoreductive agents. CONCLUSIONS This case highlights the plausible causation of secondary polycythemia that could lead to concomitant cerebral thrombosis and hemorrhagic events. The diagnosis of cerebral venous thrombosis should be considered in a patient who presents with headache, focal neurological deficits, polycythemia, and normal head computed tomography scan.

A - 119 A Case Study: the Cognitive Functioning of an Adult Patient with Recurrent Craniopharyngiomas


Arch Clin Neuropsychol. 2023 Oct 20;38(7):1291. doi: 10.1093/arclin/acad067.136.


BACKGROUND: Despite recent improvements in the treatment of cancer, little is known about the long-term survival in patients with cancer and venous thromboembolism

 


ABSTRACT


BACKGROUND: Despite recent improvements in the treatment of cancer, little is known about the long-term survival in patients with cancer and venous thromboembolism. We aimed to examine the five-year mortality of venous thromboembolism in cancer patients in a large population-based cohort study.


METHODS: Using Danish healthcare registries from 1995 to 2020, we obtained data on cancer patients with venous thromboembolism and comparison cohorts of cancer patients without venous thromboembolism, matched in terms of cancer type, age, sex, and year of cancer diagnosis, and adjusted for level of comorbidity and frailty using the Charlson Comorbidity Index Score and Hospital Frailty Risk Score, marital status, use of selected medications, and recent surgery (<90


FINDINGS: During the study period, 886,536 patients were diagnosed with cancer. Of 1882 cancer patients diagnosed at the time of their venous thromboembolism, 44.4% (835/1882) had distant metastases. In this cohort, the one- and five-year mortality cumulative incidences were 68% (1284/1882) and 84% (1578/1882), respectively, in contrast to 38% (2135/5549) and 67% (3653/5549) in the comparison cohort. The mortality rate ratio was 4.34 (95% confidence interval [CI], 3.95-4.78) for the first year of follow-up and 3.44 (95% CI 3.17-3.73) for the five-year follow-up period. Of the 23,366 patients diagnosed with venous thromboembolism after cancer diagnosis, 18% (4183/23,366) had distant metastases at the time of cancer diagnosis. The cumulative incidence of death at one year was 45% (10,465/23,366; mortality rate ratio 3.48, 95% CI 3.37-3.60) and at five years 69% (15,669/23,366; mortality rate ratio 2.57, 95% CI 2.50-2.63).


INTERPRETATION: Despite improved cancer treatment, venous thromboembolism in cancer patients is strongly associated with a poor prognosis.


FUNDING: The study was supported by grants from the Independent Research Fund Denmark (record no. 3101-00102B) and the Karen Elise Jensen Foundation.

Concomitant Cerebral Venous Thrombosis and Intracranial Hemorrhages in Presentation of a Patient with Secondary Polycythemia: A Case Report


Am J Case Rep. 2023 Oct 15;24:e941507. doi: 10.12659/AJCR.941507.


METHODS: We analyzed data from the Registro Informatizado Enfermedad TromboEmbὀlica (RIETE), an ongoing global observational registry of patients with objectively confirmed acute VTE.

 


ABSTRACT


BACKGROUND: Age is a major risk factor for venous thromboembolism (VTE), yet patients aged ≥90 years are under-represented in clinical trials of anticoagulant therapy. The objectives were to describe and compare patient clinical characteristics, treatments, and outcomes (VTE recurrence, bleeding, and mortality) during the first 3 months of anticoagulation between VTE patients aged ≥90 years and those aged <90


METHODS: We analyzed data from the Registro Informatizado Enfermedad TromboEmbὀlica (RIETE), an ongoing global observational registry of patients with objectively confirmed acute VTE.


RESULTS: From January 2001 to October 2022, 96,701 patients were registered in RIETE, of whom 3262 (3.4%) were aged ≥90 years. Patients aged ≥90 years were less likely to be men, and to have experienced cancer or recent surgery, but more likely to manifest immobility, chronic heart failure, anemia, renal insufficiency, or dementia than those aged <90


CONCLUSIONS: In patients aged ≥90 years, the difference in the outcome of anticoagulant treatment depending on the initial presentation of VTE could suggest a need for different management approaches. Clinical trials evaluating the optimal duration of anticoagulation according to initial VTE presentation are warranted to limit excess deaths in this particular population.

Impact of venous thromboembolism on the mortality in patients with cancer: a population-based cohort study


Lancet Reg Health Eur. 2023 Sep 28;34:100739. doi: 10.1016/j.lanepe.2023.100739. eCollection 2023 Nov.


 


ABSTRACT


BACKGROUND: Clinical management of patients with deep vein thrombosis (DVT) is centered around their risk of recurrent venous thromboembolism (VTE) and post-thrombotic syndrome (PTS). While chronic inflammatory disease (CID) has been established as a risk factor of (recurrent) VTE, research about its potential impact on PTS is lacking.


OBJECTIVES: We aimed to assess the risk of PTS in patients with CID, stratifying for the use of anti-inflammatory treatment.


PATIENTS/METHODS: Consecutive patients with proximal DVT and no active cancer between 2003 and 2018 received a two-year prospective follow-up. CID included inflammatory bowel disease, rheumatic diseases, and gout. Residual venous obstruction (RVO) was assessed by compressive ultrasound after 3-6 months. PTS was diagnosed using the Villalta score after 6-24 months. Hazard ratios (HR) and odds ratios (OR) were adjusted for patient characteristics. The medical ethics committee approved this study.


RESULTS: In total 82 of 801 patients had CID (10.2 %). PTS more often developed in patients with CID (35.4% vs. 18.9 %, p < 0.001) than in those without CID (HR 1.72 [1.15-2.58]). The prevalence of RVO was similar in patients with and without CID (36.8% vs. 41.4 %), and RVO was strongly associated with PTS in patients with CID (OR 3.21 [1.14-9.03]). Moreover, patients with untreated CID (44 %, n = 36) more often had RVO than those with treated CID (51.6% vs. 26.7 %, p = 0.027), and accordingly had a higher risk of PTS (HR 2.18 [1.04-4.58]).


CONCLUSIONS: Patients with CID had an increased risk of developing PTS, especially those without anti-inflammatory treatment, possibly due to an unfavorable impact on RVO-related venous pathology.

ABSTRACT


INTRODUCTION: Previous studies suggest that quality improvement initiatives focused on hospital-acquired venous thromboembolism have a positive impact on prescribing rates of venous thromboembolism prophylaxis, especially those that incorporate computerized changes.


METHODS: We conducted a quality improvement project to determine whether education and computerized prescriber order entry system changes affect venous thromboembolism prophylaxis compliance rates in hospitalized medical patients at a Comprehensive Cancer Center. Between 1 January 2021 and 31 January 2023, 37,739 non-surgical, adult patient encounters with a length of stay > 48 h were analyzed in our study. From 18 December 2021 to 8 March 2022, provider education was delivered to the three largest admitting services, and computerized prescriber order entry changes were implemented incorporating a mandatory requirement to either order venous thromboembolism prophylaxis or document a contraindication for all patients at moderate venous thromboembolism risk.


RESULTS: Monthly venous thromboembolism prophylaxis compliance rates, as defined by the Centers for Medicare and Medicaid Services VTE-1 metric, increased from a mean of 74% to 93% after the interventions. This change was driven primarily by an increased utilization of mechanical venous thromboembolism prophylaxis from 37% to 53%.


CONCLUSION: Our study demonstrated that a multi-faceted intervention incorporating provider education and computerized prescriber order entry system changes can significantly increase venous thromboembolism prophylaxis compliance rates in cancer patients.

Chronic inflammatory diseases increase the risk of post-thrombotic syndrome: A prospective cohort study


Eur J Intern Med. 2023 Oct 16:S0953-6205(23)00369-2. doi: 10.1016/j.ejim.2023.10.014. Online ahead of print.


Non-bacterial thrombotic endocarditis (NBTE) involves the deposition of fibrin and platelets on heart valves, frequently leading to systemic embolism.

 


ABSTRACT


Non-bacterial thrombotic endocarditis (NBTE) involves the deposition of fibrin and platelets on heart valves, frequently leading to systemic embolism. The association between NBTE and cancer demands thorough investigation in cases lacking an evident cause. This case report elucidates the clinical course of a nonsmoking woman in her sixties with NBTE linked to pulmonary adenocarcinoma. The patient, who had a history of multiple sclerosis (MS) and was receiving dimethyl fumarate treatment, presented to the emergency department with stroke-like symptoms. Diagnostic challenges arose due to preexisting motor sensory impairment from MS. Initial evaluations revealed hypocapnia and elevated inflammatory markers. Blood cultures were obtained twice, and imaging confirmed pneumonia, left pleural effusion, and chronic pulmonary embolism while excluding acute vascular events or intracranial hemorrhage. The first transthoracic echocardiogram (TTE) indicated no cardiac abnormalities. Treatment encompassed parenteral antibiotics, systemic anticoagulation, and admission to medical floors. Although the initial treatment yielded a positive clinical response, subsequent complications emerged. On the tenth day, the patient required additional interventions, including broad-spectrum antibiotics and supplemental oxygen. A follow-up chest X-ray revealed persistent pneumonia and pleural effusion, and blood cultures upon admission returned negative. A subsequent head MRI confirmed an embolic stroke and displayed evidence of MS progression. Around the twentieth day, empirical treatment for infective endocarditis was initiated, and an 8 mm vegetation on the aortic valve was identified via transesophageal echocardiography (TOE). Acute pulmonary edema prompted a transfer to the intermediate care unit. Further investigations, including left thoracocentesis and CT, unveiled exudate and metastatic lesions in the liver, ilium, and kidney. Unfortunately, on the twenty-fifth day, the patient experienced acute myocardial infarction, right leg ischemia, disseminated intravascular coagulation, and shock. Pleural fluid analysis revealed malignant cells suggestive of lung adenocarcinoma. This case underscores the pivotal role of timely NBTE recognition and the search for malignancy when workup for infective endocarditis and autoimmune panels is negative. Moreover, it emphasizes the significance of vigilant monitoring, particularly in immunocompromised individuals or those with preexisting neurological deficits, especially when new neurological symptoms manifest. These insights significantly contribute to the comprehension of NBTE management and its implications for analogous patient cohorts.

ABSTRACT


(1) Background: Central venous access devices (CVADs) have been commonly employed during various courses of anticancer treatment. Currently, there are a few types of clinically available CVADs, which are associated with short-term and long-term complications. However, little is known about the complication rates when CVADs are used only in palliative care settings. We therefore performed a systematic review and meta-analysis of all the published literature to evaluate the complication rates of CVADs in this clinical setting. (2) Methods: A systematic review and meta-analysis were conducted to identify publications from PubMed/MEDLINE, Embase (Ovid), Scopus, Cochrane Library, CINAHL, Google Scholar, and trial registries. Publications reporting the complication rates of PICCs, central lines, and PORTs in palliative settings for terminally ill cancer patients were included, while those on the use of systemic anticancer therapy and peripheral venous catheters were excluded. The outcome measures included overall complication rate, rate of catheter-related bloodstream infection (CRBSI), and rate of thromboembolism (TE). This systematic review was registered with PROSPERO (CRD42023404489). (3) Results: Five publications with 327 patients were analyzed, including four studies on PICCs and one study on central lines. No studies on PORTs were eligible for analysis. The overall complication rate for PICCs (pooled estimate 7.02%, 95% CI 0.27-19.10) was higher than that for central lines (1.44%, 95% CI 0.30-4.14, p = 0.002). The risk of CRBSI with PICCs (2.03%, 95% CI 0.00-9.62) was also higher than that with central lines (0.96%, 95% CI 0.12-3.41, p = 0.046). PICCs also had a trend of a higher risk of TE (2.10%, 95% CI 0.00-12.22) compared to central lines (0.48%, 95% CI 0.01-2.64, p = 0.061). (4) Conclusions: PICCs for palliative cancer care were found to have greater complications than central lines. This might aid in the formulation of future recommendation guidelines on the choice of CVAD in this setting.

ABSTRACT


INTRODUCTION: Limited data exist on the risk of venous and arterial thromboembolisms (VTE and ATE) in patients receiving cetuximab plus chemotherapy. We aimed to determine the thromboembolic risk of patients with recurrent/metastatic colorectal cancer (CRC) treated with cetuximab plus chemotherapy compared to chemotherapy alone.


METHODS: This population-based study used nationwide claims data from the Health Insurance Review and Assessment Service of South Korea from 2013 to 2020. Patients with recurrent/metastatic CRC treated with first-line oxaliplatin- or irinotecan-based doublets with or without cetuximab and no secondary prevention for VTE and ATE were included. Primary outcomes were the occurrence of any thromboembolic events, VTE, and ATE, which were determined using the cumulative incidence method incorporating death as a competing event.


RESULTS: We identified 19,723 patients (cetuximab plus chemotherapy, N = 7630; chemotherapy alone, N = 12,093). The cumulative incidence of any thromboembolic events in patients with cetuximab plus chemotherapy was significantly higher than in those receiving chemotherapy alone (6-month, 5.62 % vs. 3.58 %, P < 0.0001). The rates of VTE (6-month, 5.11 % vs. 3.28 %, P < 0.0001) and ATE (6-month, 0.53 % vs. 0.32 %, P = 0.0218) were also higher in patients receiving cetuximab plus chemotherapy. In multivariable analysis, cetuximab plus chemotherapy was independently associated with developing any thromboembolic events (hazard ratio [HR], 1.63; 95 % confidence interval [CI], 1.42-1.87), VTE (HR, 1.62; 95 % CI, 1.40-1.87), and ATE (HR, 1.77; 95 % CI, 1.16-2.71).


CONCLUSIONS: Cetuximab with irinotecan- or oxaliplatin-based doublet chemotherapy was associated with an increased risk of any thromboembolic events, VTE, and ATE; further studies are warranted to examine the underlying mechanisms.

ABSTRACT


BACKGROUND: The optimal therapy of venous thromboembolism (VTE) in cancer patients with renal insufficiency (RI) is unknown. Current guidelines recommend to use low-molecular-weight heparin over direct oral anticoagulants to treat VTE in cancer patients at high-risk for bleeding.


METHODS: We used the RIETE registry to compare the 6-month incidence rates of: 1) VTE recurrences vs. major bleeding; and 2) fatal pulmonary embolism (PE) vs. fatal bleeding in 3 subgroups (those with mild, moderate, or severe RI) of cancer patients receiving enoxaparin monotherapy.


RESULTS: From January 2009 through June 2022, 2,844 patients with RI received enoxaparin for ≥6 months: 1,432 (50%) had mild, 1,168 (41%) moderate, and 244 (8.6%) had severe RI. Overall, 68%, 62% and 12% respectively, received the recommended doses. Among patients with mild RI, the rates of VTE recurrences vs. major bleeding (4.6% vs. 5.4%) and fatal PE vs. fatal bleeding (1.3% vs. 1.2%) were similar. Among patients with moderate RI, VTE recurrences were half as common as major bleeding (3.1% vs. 6.3%), but fatal PE and fatal bleeding were close (1.8% vs. 1.2%). Among patients with severe RI, VTE recurrences were 3-fold less common than major bleeding (4.1% vs. 13%), but fatal PE was 3-fold more frequent than fatal bleeding (2.5% vs. 0.8%). During the first 10 days, fatal PE was 5-fold more common than fatal bleeding (2.1% vs. 0.4%).


CONCLUSIONS: Among cancer patients with severe RI, fatal PE was 5-fold more common than fatal bleeding. The recommended doses of enoxaparin in these patients should be revisited.

STUDY APPRAISAL AND SYNTHESIS METHODS: Two reviewers independently assessed eligibility, performed data extraction, and evaluated risk

 


ABSTRACT


OBJECTIVE: To provide procedure-specific estimates of the risk of symptomatic venous thromboembolism (VTE) and major bleeding, in the absence of thromboprophylaxis, following gynecologic cancer surgery.


DATA SOURCES: We conducted comprehensive searches on Embase, MEDLINE, Web of Science, and Google Scholar for observational studies. We also reviewed reference lists of eligible studies and review articles. We performed separate searches for randomized trials addressing effects of thromboprophylaxis and conducted a web-based survey on thromboprophylaxis practice.


STUDY ELIGIBILITY CRITERIA: Observational studies enrolling ≥50 adult patients undergoing gynecologic cancer surgery procedures reporting absolute incidence for at least one of the following: symptomatic pulmonary embolism, symptomatic deep vein thrombosis, symptomatic VTE, bleeding requiring reintervention (including re-exploration and angioembolization), bleeding leading to transfusion or post-operative hemoglobin <70


STUDY APPRAISAL AND SYNTHESIS METHODS: Two reviewers independently assessed eligibility, performed data extraction, and evaluated risk of bias of eligible articles. We adjusted the reported estimates for thromboprophylaxis and length of follow-up and used the median value from studies to determine cumulative incidence at 4 weeks post-surgery stratified by patient VTE risk factors, and used the GRADE approach to rate evidence certainty.

RESULTS: We included 188 studies (398,167 patients) reporting on 37 gynecologic cancer surgery procedures. The evidence certainty was generally low to very low. Median symptomatic VTE risk (in the absence of prophylaxis) was <1%2.0% in 13 of 37 (35%). The risks of VTE varied from 0.1% in low VTE risk patients undergoing cervical conization to 33.5% in high VTE risk patients undergoing pelvic exenteration. Estimates of bleeding requiring reintervention varied from <0.1%<1%

CONCLUSIONS: VTE reduction with thromboprophylaxis likely outweighs increase in bleeding requiring reintervention in many gynecologic cancer procedures (e.g., open surgery for ovarian cancer and pelvic exenteration). In some procedures (e.g., laparoscopic total hysterectomy without lymphadenectomy), thromboembolism and bleeding risks are similar, and decisions depend on individual risk prediction and values and preferences regarding VTE and bleeding.

ABSTRACT


Thrombocytopenia occurs frequently in patients with cancer-associated thrombosis (CAT), however prospective evaluation of clinical outcomes following randomization to anticoagulants is limited. The HOKUSAI VTE Cancer study was a randomized, open-label, non-inferiority, phase III trial comparing dalteparin with edoxaban in CAT patients. This post hoc analysis of Hokusai VTE Cancer Study was performed to compare outcomes in patients with platelet count ≤100 K/μL at one or more specified time points (baseline, 1-month, or 3-month) versus those without thrombocytopenia. Cumulative incidences at 180 days were calculated with death as a competing risk. The primary outcome was major bleeding; secondary outcomes were clinically relevant non-major bleeding (CRNMB), recurrent thrombosis, and survival. The analysis included 1,045 patients with primarily solid tumor malignancies (89%), median age 65 years, and 52% male. The thrombocytopenia group comprised 9.6% (N=101) of the cohort and relative to the non-thrombocytopenia cohort (N=944), experienced significantly higher major bleeding (9.0% vs. 4.0%, sub-distribution hazard ratio (SHR) 2.4, P=0.02) and CRNMB (17.9% vs. 9.6%, SHR 2.0, P=0.01). Thrombocytopenia did not impact recurrent VTE (9.8% vs. 7.4%, SHR 1.3, P=0.37) nor overall mortality (21.8% vs. 26.0%, HR 0.9, P=0.48). Major bleeding was higher in patients with thrombocytopenia and gastrointestinal malignancies receiving edoxaban versus dalteparin (16.8% vs 0, p.

ABSTRACT


INTRODUCTION AND IMPORTANCE: The thromboembolic complication of kidney's tumor is rare, and they can be the reason for the discovery of those tumor. Also the collision kidney tumor, such as a simultaneous occurrence of different histological types of adjacent neoplasms in the same organ is rare.


CASE PRESENTATION: We report a patient diagnosed with a kidney tumor discovered in the context of an etiological assessment of thrombosis, presenting with pulmonary embolism and deep vein thrombosis of the lower limb. This tumor treated by a cytoreductive nephrectomy. The histologic diagnosis of PRCC (Papillary Renal Cell Carcinoma) associated with a chromophobe cell carcinoma and sarcomatoid component was rendered.


CLINICAL DISCUSSION: The development of the tumor process and its progression to the metastatic stage is largely favored by the hypercoagulable state, and the cancer itself promotes the appearance of thrombo-enmbolic phenomena due to this phenomenon. Two major studies recommend that immediate cytoreductive nephrectomy should be offered to metastatic patients with a good general condition.


CONCLUSION: A renal tumor collision is rare, whereas the risk factors for a renal tumor collision are the same as a renal tumor without collision, just as the management of a metastatic renal tumor is the same. Understanding the thromboembolic physiopathology in the case of kidney cancer has made it possible to optimize management.

ABSTRACT


BACKGROUND: Evidenced-based interventions have been developed to prevent venous thromboembolism (VTE) in ambulatory patients with cancer, including VTE-risk assessment for all patients and targeted primary thromboprophylaxis for high-risk patients. Despite supportive evidence and recommendations, oncologists rarely assess VTE risk or provide primary prophylaxis. Our previous work identified barriers and facilitators to using VTE prevention interventions in oncology practice.


OBJECTIVES: To identify potential strategies that address the identified barriers and leverage facilitators to achieve successful implementation of evidence-based interventions for VTE prevention in oncology practice.


METHODS: We used the Implementation Research Logic Model, an implementation science framework, to map the relationships among barriers and facilitators, feasible and effective implementation strategies, and implementation and clinical outcomes that will be used to evaluate the implementation strategies.


RESULTS: We identified 12 discrete implementation strategies (eg, conducting clinician education and training and staged implementation scale-up) that address barriers and leverage facilitators through their mechanisms of action (eg, increased clinician awareness of evidence and targeting the highest effectiveness). We identified key implementation (eg, penetration, adoption, acceptability, fidelity, appropriateness, and sustainability), system (eg, integration of VTE-risk assessment into clinical workflow), and clinical (eg, lower VTE rates) outcomes targeted by the selected strategies.


CONCLUSION: Using the Implementation Research Logic Model framework and building on our knowledge of barriers and facilitators, we identified implementation strategies and important outcomes to evaluate these strategies. We will use these results to test and measure the strategies to improve the uptake of evidence-based recommendations for VTE prevention in oncology practice.

INTRODUCTION: The prediction of complications before gastric surgery is of utmost importance in shared decision making and proper counseling of the patient in order to minimize postoperative complications. Our aim was to evaluate the predictive validity of American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) risk calculator in gastric cancer patients who underwent gastrectomy.


METHODS: Preoperative assessment data of 432 patients were retrospectively reviewed and manually entered into the calculator. The accuracy of the calculator was evaluated using Pearson's chi-squared test, C-statistic, Brier score, and Hosmer-Lemeshow test.


RESULTS: The lowest Brier scores were observed in urinary tract infection, renal failure, venous thromboembolism, pneumonia, and cardiac complications. Best results were obtained for predicting sepsis, discharge to rehabilitation facility, and death (low Brier scores, C-statistic >.7, and Hosmer-Lemeshow P > .05).


CONCLUSION: The calculator had a strong performance in predicting sepsis, discharge to the rehabilitation facility, and death. However, it performed poor in predicting the most commonly observed events (any or serious complication and surgical site infection).

ABSTRACT


BACKGROUND: Patients with brain cancer have been excluded or were underrepresented in studies on the treatment of venous thromboembolism (VTE), mainly due to the fear of intracranial hemorrhage (ICH).


OBJECTIVES: The aim of this study was to provide data on the risk of ICH, recurrent VTE, and major bleeding in patients with active brain cancer.


METHODS: This was a multicenter, international cohort study at participating sites of the Registro Informatizado Enfermedad Tromboembólica Registry. Patients included in this study were classified as having known active brain cancer, active nonbrain cancer, or without active cancer. ICH at 3 months was the primary study outcome.


RESULTS: Overall, 98,377 patients with VTE were included: 616 with active brain cancer, 16,807 with active nonbrain cancer, and 80,954 without active cancer. At 3 months follow-up, ICH occurred in 2.8%, 0.3%, and 0.2% of the patients, respectively, and was fatal in 1.3%, 0.2%, and 0.1%, respectively. Both rates of major bleeding (3.7% vs 3.2% vs 1.5%, respectively) and recurrent VTE (3.9% vs 3.4% vs 1.1%, respectively) were higher in patients with brain or nonbrain cancer than in patients without cancer. Glioblastomas were associated with a numerically higher risk of ICH, fatal ICH, and recurrent VTE than other brain tumors.


CONCLUSION: In patients with VTE, active brain cancer was associated with a higher risk of ICH or fatal ICH than nonbrain or no active cancer. Further studies are needed to assess the value of different treatment approaches in patients with brain cancer and VTE.

ABSTRACT


BACKGROUND: Incidence of and risk factors for bleeding in cancer patients with venous thromboembolism (VTE) treated with apixaban are poorly described.


METHODS: We analyzed data from the prospective CAP study where 298 cancer patients with any type of VTE received 5 mg apixaban twice daily for 6 months, and then 2.5 mg apixaban twice daily for 30 months. For most analyses major bleedings and clinically relevant non-major bleedings were merged to "clinically relevant bleedings". Risk factors were estimated by odds ratios (OR) and 95% confidence intervals (CI).


RESULTS: The incidence of clinically relevant bleedings was 38% per person year during the first 6 months of treatment, 21% per person year from 7 to 12 months, and between 4% and 8% per person year from 13 to 36 months. Clinically relevant bleedings were associated with age above 74 years (OR 2.0, 95% CI 1.0-4.1), BMI below 21.7 (OR 2.3, 95% CI 1.1-4.8), and hemoglobin at baseline below 10.5 for females (OR 2.8, 95% CI 1.1-7.3) and 11.1 for males (OR 3.3, 95% CI 1.3-8.4) during the first 6 months. Gastrointestinal (GI) or urogenital cancer were not associated with clinically relevant bleedings compared with other cancers. Among patients with luminal GI-cancer, non-resected cancer had increased risk of bleeding (OR 3.4, 95% CI 1.0-11.6) compared with resected GI-cancer.


CONCLUSION: It was very few bleedings while patients were on low-dose apixaban. Factors associated with bleeding in patients treated with full-dose apixaban were high age, low BMI, and low hemoglobin, and probably non-resected luminal GI-cancer.

Acute venous thromboembolism in patients with brain cancer: clinical course

ABSTRACT


This study aims to summarize the available data and determine if the presence of venous thromboembolism (VTE) immune-related adverse event (irAE) in patients with immune checkpoint inhibitor (ICI) therapy is associated with improved treatment efficacy and clinical outcomes, which in turn was used to help optimize patient selection for anticoagulation therapy and inform rational treatment strategies for overcoming the mechanisms of ICI resistance. PubMed, Embase, Web of Science, and Cochrane Library were searched up to March 18, 2023, for studies assessing the relationship between VTE irAE development during ICI therapy and cancer outcomes. Seven primary articles with a total of 4437 patients were included in the overall survival (OS) meta-analysis. Patients with VTE had a significant increase in overall mortality compared to patients without VTE in adjusted hazard ratios (HRs 1.36, 95% confidence interval [CI] 1.06-1.75, P = .02). In the studies where immortal time bias (ITB) was accounted for, patients with VTE irAE also had poor OS than those without. HR and the corresponding 95% CI values in the non-ITB group were 2.53 (1.75-3.66, P < .00001) with low heterogeneity (P = .17, I2 = 48%) and 1.21 (1.06-1.37, P = .004) in the ITB group with no heterogeneity (P = .95, I2 = 0%), respectively. Despite the heterogeneity identified, the evidence does suggest that VTE irAE occurrence could be served as a prognostic indicator, with higher frequencies of occurrence associated with poorer OS. However, the fundamental role of this association with clinical consequences should be further investigated in large cohorts and clinical trials.

ABSTRACT


PURPOSE: Pulmonary embolism (PE) is a significant contributor to mortality in patients with cancer. Although anticoagulation serves as the cornerstone of treatment for cancer-associated PE, it has not been emphasized in real-world settings. The aim of this study was to examine the impact of suboptimal anticoagulant treatment on the prognosis of cancer-associated PE.


METHODS: A cohort of 356 individuals newly diagnosed with acute PE were enrolled. The primary outcome of the study was recurrent venous thromboembolism (VTE), and the secondary outcomes were all-cause mortality and major bleeding (consisting of a reduction in the hemoglobin level by at least 20 g/L, transfusion of at least 2 units of blood, or symptomatic bleeding in a critical area or organ or fatal bleeding).


FINDINGS: Of the total participants, 156 (43.8%) were diagnosed with cancer. A comparison between the cancer and noncancer groups revealed that patients with cancer were more frequently asymptomatic (41.0% vs 4.5%; P < 0.001), less likely to have right ventricular dysfunction (4.5% vs 14.0%; P = 0.001), received less anticoagulant treatment during hospitalization (85.3% vs 98.5%; P < 0.001), and had a shorter duration of anticoagulation (5.02 [7.40] months vs 14.19 [10.65] months; P < 0.001). In addition, patients with cancer were found to be at a higher risk of recurrent VTE (17.3% vs 4.0%; P < 0.001) and all-cause mortality (23.7% vs 10.5%; P = 0.001). Multiple Cox regression analysis indicated that discontinuation of anticoagulation at 3 months was a significant risk factor for recurrent VTE in the cancer group (HR, 15.815; 95% CI, 3.047-82.079; P = 0.001).


IMPLICATIONS: The brief duration of anticoagulation therapy and elevated likelihood of recurrent VTE serve as cautionary indicators for the need to enhance awareness of standardized anticoagulant treatment for cancer-associated PE. The ultimate goal is to enhance patient prognosis and quality of life.

Associations Between Immune-Related Venous Thromboembolism and Efficacy of Immune Checkpoint Inhibitors: A Systematic Review and Meta-Analysis


Clin Appl Thromb Hemost. 2023 Jan-Dec;29:10760296231206799. doi: 10.1177/10760296231206799.


 


ABSTRACT


Low molecular weight heparins (LMWH) and anti-Xa direct oral anti-coagulants (DOACs) are recommended for the long-term treatment of cancer-associated thrombosis (CAT) based on well-documented randomised controlled trials. Anti-Xa DOACs are viewed as a first choice for the treatment of patients with CAT. A large number of drug-drug interactions have been reported between DOACs and chemotherapy drugs, modifying circulating levels of DOAC leading to fears of increased bleeding risks or thrombotic recurrence. Progresses in anti-neoplastic therapies have improved the prognosis and the survival, thus increasing the prevalence of frail patients with cancer. However, since frailties tend to be excluded from large trials due to multiple co-morbidities, current guidelines are not fully applicable to this population. The management of these frail patients with CAT is particularly complex and requires a risk assessment on a case-by-case basis with specific focus on cancer, patient-related risk factors and drug-drug interactions. In this brief review we have identified age, co-morbidities and co-medications as key factors of frailty that require careful attention and we have developed a therapeutic decision algorithm to help clinicians optimising the use of anti-coagulants in patients with cancer with CAT, especially in case of anti-Xa DOACs concomitant medications. With the evaluation of the bleeding risk according to the type of cancer, and anticipating drug-drug interactions intensity, taking into account patient frailties allows the optimisation of the anti-coagulant choice. A systematic collaboration between oncologists, vascular pathology specialists and pharmacists is warranted to ensure an optimal patient management. Clinical studies are needed to determine the real impact of these interactions.

Arterial (ATE) and venous (VTE) thromboembolic complications are common causes of morbidity and mortality in BCR-ABL-negative

 


ABSTRACT


Arterial (ATE) and venous (VTE) thromboembolic complications are common causes of morbidity and mortality in BCR-ABL-negative myeloproliferative neoplasms (MPNs). However, there are few studies that include all MPN subtypes and focus on both MPN-associated ATE and VTE. In our single-center retrospective study of 832 MPN patients, a total of 180 first thromboembolic events occurred during a median follow-up of 6.6 years (range: 0-37.6 years), of which 105 were VTE and 75 were ATE. The probability of a vascular event at the end of the follow-up period was 36.2%, and the incidence rate for all first ATE/VTE was 2.43% patient/year. The most frequent VTE localizations were deep vein thrombosis with or without pulmonary embolism (incidence rate: 0.59% patient/year), while strokes were the most frequent ATE with an incidence rate of 0.32% patient/year. When comparing the group of patients with ATE/VTE (n = 180) and the group without such an event (n = 652) using multivariate Cox regression analyses, patients with polycythemia vera (hazard ratio [HR]: 1.660; [95% confidence interval [CI] 1.206, 2.286]) had a significantly higher risk of a thromboembolic event than the other MPN subtypes. In contrast, patients with a CALR mutation had a significantly lower risk of thromboembolism compared with JAK2-mutated MPN patients (HR: 0.346; [95% CI: 0.172, 0.699]). In summary, a high incidence of MPN-associated VTE and ATE was observed in our retrospective study. While PV patients or generally JAK2-mutated MPN patients had a significantly increased risk of such vascular events, this risk was reduced in CALR-mutated MPN patients.

ABSTRACT


Atrial fibrillation (AF) can increase thrombosis, especially arterial thrombosis, and some studies show that AF patients have a higher risk of developing pulmonary embolism (PE). The objective of our study is to investigate whether there is a direct causal effect of AF on PE. A two-sample Mendelian randomization (MR) approach was utilized to determine whether there is a causal relationship between AF and PE. European population-based consortia provided statistical data on the associations between Single Nucleotide Polymorphisms (SNPs) and relevant traits. The AF dataset was obtained from genome-wide association studies (GWAS) comprising 60,620 cases and 970,216 controls, while a GWAS of 1846 cases and 461,164 controls identified genetic variations associated with PE. Estimation of the causal effect was mainly performed using the random effects inverse-variance weighted method (IVW). Additionally, other tests such as MR-Egger intercept, MR-PRESSO, Cochran's Q test, "Leave-one-out," and funnel plots were conducted to assess the extent of pleiotropy and heterogeneity. Using 70 SNPs, there was no evidence to suggest an association between genetically predicted AF and risk of PE with multiplicative random-effects IVW MR analysis (odds ratio = 1.0003, 95% confidence interval: 0.9998-1.0008, P = 0.20). A null association was also observed in other methods. MR-Egger regression and MR-PRESSO respectively showed no evidence of directional (intercept, - 2.25; P = 0.94) and horizontal(P-value in the global heterogeneity test = 0.99) pleiotropic effect across the genetic variants. No substantial evidence was found to support the causal role of AF in the development of PE. Causal effect of atrial fibrillation on pulmonary embolism: a Mendelian randomization study. AF atrial fibrillation, PE pulmonary embolism, GWAS genome-wide association studies, SNPs single nucleotide polymorphisms, OR odds ratio, CI confidence interval.

ABSTRACT


OBJECTIVE: To compare the venous thromboembolism (VTE) rate in patients with ovarian cancer undergoing neoadjuvant chemotherapy before and after implementing routine thromboprophylaxis.


METHODS: This is a quasi-experimental pre-post study evaluating the VTE rate in patients with ovarian cancer who received neoadjuvant chemotherapy following a quality improvement initiative of routine thromboprophylaxis within a single healthcare system that started in January 2017. Patients were excluded if VTE was diagnosed before initiating chemotherapy. Patient factors and perioperative variables of interest were investigated for their association with VTE through univariate and multivariate models.


RESULTS: Of the 136 patients in the pre-implementation group, 3.7% (n = 5) received thromboprophylaxis. Of the 154 patients in the post-implementation group, 65.6% (n = 101) received thromboprophylaxis. Provider compliance varied from 51% in 2019 to 79.3% in 2021. The overall rate of VTE, from the start of chemotherapy to the end of treatment, was 21.3% (n = 29) pre- and 8.4% (n = 13) in the post-implementation group (p < 0.01). There was no difference in major bleeding events between groups (0% vs. 0.68%, p = 0.63). On univariate analysis, thromboprophylaxis (OR 0.19; 95% CI 0.07-0.52) and post-implementation period (OR 0.34; 95% CI 0.17-0.69) were associated with a decreased risk of any VTE during primary treatment. On multivariate analysis, only thromboprophylaxis remained significantly associated with reduced VTE rates (aOR 0.19; 95% CI 0.07-0.53).


CONCLUSION: Routine thromboprophylaxis during neoadjuvant chemotherapy is associated with reduced risk of VTE throughout primary treatment and is not associated with increased bleeding events.

ABSTRACT


BACKGROUND: The way in which to prevent recurrent venous thromboembolism (VTE) is an unmet clinical need in cancer patients. International guidelines only provide conditional recommendations and do not specify which anticoagulant and dose should be used. In the last 2 years, we have been using low-dose rivaroxaban to prevent VTE recurrences in cancer patients. The results of this real-life experience are presented in this study.


METHODS: All patients had cancer and had previously completed a cycle of at least six months of full-dose anticoagulation for the treatment of a VTE index event, before receiving a prescription of low-dose rivaroxaban (10 mg once daily) for secondary prevention of VTE. Effectiveness and safety of this therapeutic regimen were evaluated in terms of VTE recurrences, major bleedings (MB), and clinically relevant non-major bleedings (CRNMB).


RESULTS: The analysis included 106 cancer patients. Their median age was 60 years (IQR 50-69). Metastatic cancer was present in 87 patients (82.1%). Six patients (5.7%) had brain metastases. Over a median follow-up time of 333 days (IQR 156-484), the incidence of VTE recurrences was 3.8% (95%CI 1.0-9.4), with a recurrence rate of 4.0 per 100 person-years (95%CI 1.1-10.2). We observed no MB (0.0%) and three CRNMB (2.8%) (95%CI 0.6-8.1).


CONCLUSIONS: Low-dose rivaroxaban is potentially effective and safe in cancer patients that require prevention of recurrent VTE. Large-scale studies are needed to confirm these findings.

ABSTRACT


BACKGROUND: Accurate diagnostic and prognostic predictions of venous thromboembolism (VTE) are crucial for VTE management. Artificial intelligence (AI) enables autonomous identification of the most predictive patterns from large complex data. Although evidence regarding its performance in VTE prediction is emerging, a comprehensive analysis of performance is lacking.


AIMS: To systematically review the performance of AI in the diagnosis and prediction of VTE and compare it to clinical risk assessment models (RAMs) or logistic regression models.


METHODS: A systematic literature search was performed using PubMed, MEDLINE, EMBASE, and Web of Science from inception to April 20, 2021. Search terms included "artificial intelligence" and "venous thromboembolism." Eligible criteria were original studies evaluating AI in the prediction of VTE in adults and reporting one of the following outcomes: sensitivity, specificity, positive predictive value, negative predictive value, or area under receiver operating curve (AUC). Risks of bias were assessed using the PROBAST tool. Unpaired t-test was performed to compare the mean AUC from AI versus conventional methods (RAMs or logistic regression models).


RESULTS: A total of 20 studies were included. Number of participants ranged from 31 to 111 888. The AI-based models included artificial neural network (six studies), support vector machines (four studies), Bayesian methods (one study), super learner ensemble (one study), genetic programming (one study), unspecified machine learning models (two studies), and multiple machine learning models (five studies). Twelve studies (60%) had both training and testing cohorts. Among 14 studies (70%) where AUCs were reported, the mean AUC for AI versus conventional methods were 0.79 (95% CI: 0.74-0.85) versus 0.61 (95% CI: 0.54-0.68), respectively (p < .001). However, the good to excellent discriminative performance of AI methods is unlikely to be replicated when used in clinical practice, because most studies had high risk of bias due to missing data handling and outcome determination.


CONCLUSION: The use of AI appears to improve the accuracy of diagnostic and prognostic prediction of VTE over conventional risk models; however, there was a high risk of bias observed across studies. Future studies should focus on transparent reporting, external validation, and clinical application of these models.

ABSTRACT


Artificial intelligence tools, particularly convolutional neural networks (CNNs), are transforming healthcare by enhancing predictive, diagnostic, and decision-making capabilities. This review provides an accessible and practical explanation of CNNs for clinicians and highlights their relevance in medical image analysis. CNNs have shown themselves to be exceptionally useful in computer vision, a field that enables machines to 'see' and interpret visual data. Understanding how these models work can help clinicians leverage their full potential, especially as artificial intelligence continues to evolve and integrate into healthcare. CNNs have already demonstrated their efficacy in diverse medical fields, including radiology, histopathology, and medical photography. In radiology, CNNs have been used to automate the assessment of conditions such as pneumonia, pulmonary embolism, and rectal cancer. In histopathology, CNNs have been used to assess and classify colorectal polyps, gastric epithelial tumours, as well as assist in the assessment of multiple malignancies. In medical photography, CNNs have been used to assess retinal diseases and skin conditions, and to detect gastric and colorectal polyps during endoscopic procedures. In surgical laparoscopy, they may provide intraoperative assistance to surgeons, helping interpret surgical anatomy and demonstrate safe dissection zones. The integration of CNNs into medical image analysis promises to enhance diagnostic accuracy, streamline workflow efficiency, and expand access to expert-level image analysis, contributing to the ultimate goal of delivering further improvements in patient and healthcare outcomes.

Artificial intelligence in the prediction of venous thromboembolism: A systematic review and pooled analysis


Eur J Haematol. 2023 Oct 4. doi: 10.1111/ejh.14110. Online ahead of print.


 


ABSTRACT


The implantation of a totally implantable central venous(CV)access port is considered a risk factor for venous thromboembolism( VTE). In the treatment of catheter-related thrombosis(CRT), both European and American guidelines recommend anticoagulation therapy with catheters in place. We experienced 2 cases of upper extremity deep vein thrombosis (UEDVT)after the implantation of CV access ports through the left subclavian vein for adjuvant chemotherapy in patients with resected breast cancer. Both patients were successfully treated with direct oral anticoagulants(DOAC) while the port remained in place with a careful follow-up that included monitoring of serum D-dimer levels. The administration of DOAC to CRT that develops in patients undergoing postoperative adjuvant chemotherapy for breast cancer may be relatively safe, with a low potential for adverse events such as bleeding.

ABSTRACT


BACKGROUND: The safety and efficacy of direct-acting oral anticoagulants (DOACs) for therapeutic anticoagulation in the setting of primary or metastatic brain cancer is not known.


OBJECTIVE: To conduct a meta-analysis and systematic review of studies that compare the risk of intracranial hemorrhage (ICH) in patients with brain cancer treated with DOACs vs. LMWH.


METHODS: A literature search was conducted using PubMed, EMBASE, and Cochrane databases. Summary statistics were obtained by calculating the risk ratio (RR), and heterogeneity across studies was estimated using the I2 statistic. A total of 10 retrospective studies (n=1,638) met criteria for inclusion. The primary endpoint was the pooled RR for ICH in patients with brain tumors receiving anticoagulation with DOACs compared with those receiving LMWH. Secondary analyses included the risk of fatal ICH in each subgroup.


RESULTS: The pooled RR for ICH in patients receiving DOACs vs. those receiving LMWH was 0.65 (95% confidence interval [CI], 0.36-1.17; P = 0.15; I2 = 50%). In studies evaluating primary brain cancer, there was a reduction in risk of ICH with DOACs (RR, 0.35; 95% CI, 0.18-0.69; P = 0.003; I2 = 0%). In patients with metastatic brain cancer, there was no difference in the risk of ICH with type of anticoagulation (RR, 1.05; 95% CI, 0.71-1.56; P = 0.80; I2 = 0%). The overall risk of fatal ICH was not different between anticoagulants.


DISCUSSION: The risk of ICH in patients with brain cancer receiving therapeutic anticoagulation varies by anticoagulation agent and diagnosis of primary or metastatic disease.

BACKGROUND Pulmonary embolism secondary to deep vein thrombosis (DVT) with cor pulmonale is commonly associated with risk factors

 


ABSTRACT


BACKGROUND Pulmonary embolism secondary to deep vein thrombosis (DVT) with cor pulmonale is commonly associated with risk factors including surgery, cancer, and prolonged immobility. Cocaine is known to cause vasoconstriction and has a prothrombotic effect. Prolonged and heavy use of cocaine can also cause inflammation and liver damage. However, data on its potential role in causing pulmonary embolism and direct hepatotoxicity in cases of episodic use are scarce. CASE REPORT A 34-year-old man with no significant medical history except for episodic cocaine use presented in respiratory distress. Workup revealed submassive pulmonary embolism with pulmonary infarctions complicated by pneumonia, hypoxemic respiratory failure, and anemia. He was treated with anticoagulation and intensive care. On day 5 of hospitalization, the patient had an acute hepatic injury. His alanine aminotransferase level peaked at over 2000 IU/L on day 7, until finally tapering. Liver failure was found to be secondary to cocaine use. Liver enzyme levels improved with supportive care. He was discharged with apixaban and continued liver enzyme monitoring. CONCLUSIONS When investigating the cause of venous thromboembolism and transaminitis, evaluating cocaine use via patient history or laboratory analysis of cocaine and its metabolites should be considered. Cocaine is known to cause vasoconstriction and has a prothrombotic effect, although data on its potential role in causing pulmonary embolism and direct hepatotoxicity in cases of episodic use are scarce. Further investigation, such as cohort studies, could help strengthen our understanding of the relationship between cocaine use, acute hepatic injury, and pulmonary embolism.

Comparison of Direct Oral Anticoagulants versus Low Molecular Weight Heparin in Primary and Metastatic Brain Cancers: A Meta-Analysis and Systematic Review


J Thromb Haemost. 2023 Oct 20:S1538-7836(23)00779-1. doi: 10.1016/j.jtha.2023.10.011. Online ahead of print.


 


ABSTRACT


D-dimer, a soluble fibrin degradation product that originates from plasmin-induced degradation of cross-linked fibrin, is an important biomarker of coagulation activation and secondary fibrinolysis that is routinely used to rule out venous thromboembolism (VTE), to evaluate the risk of VTE recurrence as well as the optimal duration of anticoagulant therapy. Besides VTE, D-dimer may be high due to physiologic conditions, including aging, pregnancy and strenuous physical activity. In addition, several disorders have been associated with increased D-dimer levels, spanning from disseminated intravascular coagulation to infectious diseases and cancers. Thus, it is far from unusual for hematologists to have to deal with ambulatory individuals presenting with increased Ddimer without signs or symptoms of thrombus formation. To the management of these cases by the hematologist is dedicated this narrative review.

Episodic Cocaine Use as a Cause of Venous Thromboembolism and Acute Liver Injury


Am J Case Rep. 2023 Oct 24;24:e941360. doi: 10.12659/AJCR.941360.


 


ABSTRACT


BACKGROUND: Nonpersistence in anticoagulation therapy is common and associated with undesirable clinical outcomes in patients with venous thromboembolism (VTE).


METHODS: We investigated preceding clinical events of treatment nonpersistence (e.g., switching, discontinuing, or restarting) in VTE patients with and without active cancer using Korean claims database.


RESULTS: Clinically significant events including thromboembolic events, hepatic function change and surgery preceded treatment nonpersistence, but heterogeneous distributions of clinical events were observed in the presence of active cancer. Patients with active cancer had a low rate of clinical events preceding treatment nonpersistence, and new active cancer diagnosis in the nonactive cancer group was most common before the switch to parenteral anticoagulants from warfarin or non-vitamin K antagonist oral anticoagulants (NOACs).


CONCLUSION: These findings suggest that clinically significant events can precede treatment nonpersistence and largely paralleled current guidelines for patients with VTE, whereas heterogeneous distributions of clinical events were observed in the presence of active cancer.

ABSTRACT


Venous thromboembolism (VTE), a condition involving deep vein thrombosis and embolism, can cause death when left untreated. Hospitalized patients and those who have recently undergone surgery or have a cancer diagnosis are at increased risk for VTE development. The updated AORN "Guideline for prevention of venous thromboembolism" provides perioperative nurses with a variety of evidence-based recommendations associated with the topic. This article provides an overview of the guideline and discusses recommendations for a VTE protocol, VTE and bleeding risk assessments, pharmacologic and mechanical VTE prophylaxis, postoperative ambulation, and patient and family education. It also includes a scenario that illustrates the importance of the VTE assessment and the use of mechanical prophylaxis for high-risk patients undergoing operative or other invasive procedures. Perioperative nurses should review the guideline in its entirety and implement recommendations in operative and procedural settings.

Heterogeneous distributions in clinical events preceding anticoagulant treatment nonpersistence in patients with venous thromboembolism stratified by active cancer: A nationwide cohort study


Cancer Med. 2023 Oct 26. doi: 10.1002/cam4.6626. Online ahead of print.


Descriptive data included demographics, anthropometrics, HA-VTE characteristics (i.e., type, location, and timing), central venous catheterization data

 


ABSTRACT


OBJECTIVES: To determine if the duration of invasive mechanical ventilation (IMV) was associated with hospital-acquired venous thromboembolism (HA-VTE) among critically ill children.


DESIGN: A multicenter, matched case-control study as a secondary analysis of Children's Hospital Acquired Thrombosis (CHAT) Consortium registry.


SETTING: PICUs within U.S. CHAT Consortium participating centers.


PATIENTS: Children younger than 21 years old admitted to a PICU receiving IMV for greater than or equal to 1 day duration from January 2012 to March 2022 were included for study. Cases with HA-VTE were matched 1:2 to controls without HA-VTE by patient age groups: younger than 1, 1-12, and older than 12 years.


INTERVENTIONS: None.


MEASUREMENTS AND MAIN RESULTS: The primary outcome was IMV duration in days. Descriptive data included demographics, anthropometrics, HA-VTE characteristics (i.e., type, location, and timing), central venous catheterization data, thromboprophylaxis practices, and Braden Q mobility scores. Descriptive, comparative, and associative (multivariate conditional logistic regression for HA-VTE) statistics were employed. A total of 152 cases were matched to 304 controls. Cases with HA-VTE were diagnosed at a median of 7 days (interquartile range [IQR], 3-16 d) after IMV. The HA-VTE were limb deep venous thromboses in 130 of 152 (85.5%) and frequently central venous catheterization-related (111/152, 73%). Cases with HA-VTE experienced a longer length of stay (median, 34 d [IQR, 18-62 d] vs. 11.5 d [IQR, 6-21 d]; p < 0.001) and IMV duration (median, 7 d [IQR, 4-15 d] vs. 4 d [IQR, 1-7 d]; p < 0.001) as compared with controls. In a multivariate logistic model, greater IMV duration (adjusted odds ratio, 1.09; 95% CI, 1.01-1.17; p = 0.023) was independently associated with HA-VTE.


CONCLUSIONS: Among critically ill children undergoing IMV, HA-VTE was associated with greater IMV duration. If prospectively validated, IMV duration should be included as part of prothrombotic risk stratification and future pediatric thromboprophylaxis trials.

Guidelines in Practice: Prevention of Venous Thromboembolism


AORN J. 2023 Nov;118(5):321-328. doi: 10.1002/aorn.14019.


OBJECTIVE: Currently, immune checkpoint inhibitors (ICIs) therapy is one of the main methods of treatment in non-small cell lung cancer (NSCLC)

 


ABSTRACT


OBJECTIVE: Currently, immune checkpoint inhibitors (ICIs) therapy is one of the main methods of treatment in non-small cell lung cancer (NSCLC). This study aimed to explore the risk factors of VTE and evaluate the effect of ICIs on VTE in patients with NSCLC.


RESEARCH DESIGN AND METHODS: We retrospectively studied patients with NSCLC who were divided into VTE group and without VTE (Non-VTE) group. We identified the risk factors of VTE in NSCLC patients and evaluated the effect of ICIs on VTE in NSCLC patients.


RESULTS: We found that clinical stage III-IV (P = 0.015) and Khorana score (KS) ≥ 2 (P = 0.047) were independent risk factors for the occurrence of VTE in NSCLC, and treatment with ICIs reduced the risk of VTE occurrence (P = 0.028). There were no differences of survival rates in the 12-month (P = 0.449), 24-month (P = 0.412), or 36-month (P = 0.315) between the VTE and non-VTE groups. History of anti-angiogenic therapy (P = 0.033) and chronic obstructive pulmonary disease (COPD) (P = 0.046) were independent risk factors for VTE in NSCLC patients who were treated with ICIs.


CONCLUSION: This study suggests that we should strengthen anticoagulant therapy when using ICIs for NSCLC patients with a history of anti-angiogenic therapy and COPD.

Hospital-Acquired Venous Thromboembolism and Invasive Mechanical Ventilation: A Report From the Children's Hospital Acquired Thrombosis Consortium


Pediatr Crit Care Med. 2023 Oct 26. doi: 10.1097/PCC.0000000000003383. Online ahead of print.


METHODS: 100 patients with lung cancer admitted to the 2nd Affiliated Hospital of Hainan Medical University from April 2020 to April 2022 were selected.

 


ABSTRACT


OBJECTIVE: To observe the effect of nurse-patient co-management mode on preventing venous thromboembolism (VTE) in lung cancer patients with carboplatin and gemcitabine chemotherapy after peripheral venipuncture central venous catheterization (PICC).


METHODS: 100 patients with lung cancer admitted to the 2nd Affiliated Hospital of Hainan Medical University from April 2020 to April 2022 were selected. All patients received a combination chemotherapy of carboplatin and gemcitabine and PICC catheterization. The patients were divided into an observation group and a control group by 1:1 simple random method, with 50 cases in each group. Patients in the control group were given routine nursing for lung cancer, and patients in the observation group were treated with nurse-patient co-management mode, and nursing intervention lasted for 2 months. General Comfort Questionnaire, self-management ability, quality of life, Self-care ability Scale, self-rating Anxiety Scale (SAS), and self-rating depression Scale were compared before and after intervention between the two groups. The recovery of immune ability indices (CD3+, CD3+CD4+, CD3+CD8+, CD3+CD4+/CD3+CD8+) in 2 groups were detected. Complications after PICC catheterization were recorded in the two groups.


RESULTS: After nursing, self-rating depression Scale and self-rating Anxiety Scale scores in both groups were significantly decreased, which were lower in the observation group than the control group (P < .001). After nursing, scores of self-concept, self-responsibility, self-care skills, and health knowledge level were significantly increased in both groups, which were higher in the observation group than control group (P < .001). After nursing, scores on the General Comfort Questionnaire, self-management scale, and quality of life were increased in both groups, which were higher in the observation group than control group (P < .0501). After nursing care, the immune competence indices of both patients increased significantly, and the immune indexes of CD3+, CD3+CD4+, and CD3+ CD4+/CD3+CD8+ in the observation group were significantly higher than those in the control group (P < .05). The total incidence of complications in the observation group was significantly lower than that in the control group (8.00% vs. 26.00%, P < .001), and the incidence of venous thromboembolism was significantly lower than that in the control group (2.00% vs. 14.00%, P < .001).


CONCLUSION: The nurse-patient co-management model has shown to be effective in reducing the incidence of venous thromboembolism in patients who have undergone PICC catheterization while receiving carboplatin and gemcitabine chemotherapy. This model also helps patients improve their self-care and self-management abilities, alleviates adverse psychological effects, and contributes to the recovery of their immune system.

Evaluating the effect of immune checkpoint inhibitors on venous thromboembolism in non-small cell lung cancer patients


Expert Rev Hematol. 2023 Oct 26:1-8. doi: 10.1080/17474086.2023.2276209. Online ahead of print.


METHODS: in the Danish Lung Cancer Registry. VTE events in the year after surgery were assessed by stage, patient characteristics, and surgical procedure.

 



ABSTRACT


BACKGROUND: Venous thromboembolism (VTE) is a potentially preventable serious complication in lung cancer patients undergoing thoracic surgery. We examined the risk and timing of VTE following surgery for primary non-small cell lung cancer (NSCLC).


METHODS: in the Danish Lung Cancer Registry. VTE events in the year after surgery were assessed by stage, patient characteristics, and surgical procedure.


RESULTS: We identified 13,197 patients who underwent surgery for NSCLC in 2003-2021 (mean age 67.6 years, 50% female); 10,524 (79.7%) had stage I-II NSCLS and 2673 (20.3%) had stage III-IV. During one-year follow-up, there were 335 VTE events, yielding a rate of 2.87 events/100 person-years and an absolute risk of 3.3% (95% CI 2.3-4.0). VTE risk increased with advancing cancer stage (1.8% for stage I versus 4.1% for stage IV), but varied little by pathological type, sex, and comorbidity level. Bilobectomy was associated with highest VTE risk (4.8%, 95% CI 3.2-6.9), followed by pneumonectomy (3.6%, 95% CI 2.5-5.1). The hazard of VTE was highest during the first three months after surgery, whereafter it declined. For stage IV cancer hazards increased again after six months. At one-year, all-cause death was 12.6% (95% CI: 12.0-13.1 %).


CONCLUSIONS: Among patients undergoing surgery for NSCLC, 3.3% developed VTE, most commonly within 3 months postoperatively. Prolonged thromboprophylaxis could be considered, particularly in those with advanced cancer stage and undergoing extended resections.

A Novel Model to Prevent Venous Thromboembolism in Patients with Lung Cancer


Altern Ther Health Med. 2023 Oct 27:AT9245. Online ahead of print.

Background and Objectives: Venous thromboembolism (VTE) is common in cancer patients. Anticoagulant therapy with low-molecular-weight

 


ABSTRACT


Background and Objectives: Venous thromboembolism (VTE) is common in cancer patients. Anticoagulant therapy with low-molecular-weight heparins (LMWHs) and direct oral anticoagulants (DOACs), such as dalteparin and apixaban, have demonstrated efficacy and safety. However, more comparative research of these drugs is still needed. This study aimed to synthesize evidence on the efficacy of apixaban compared to dalteparin in reducing recurrent VTE, major bleeding, and clinically relevant non-major bleeding associated with cancer. Materials and Methods: We systematically searched the PubMed, Scopus, Web of Science, Embase, Cochrane Library, and ClinicalTrials databases up to 5 January 2023, for randomized controlled trials comparing apixaban versus dalteparin as treatment for cancer-associated VTE. Five studies were included. Effects according to meta-analyses were reported as relative risks (RRs) and their 95% confidence intervals (CIs). Results: It was found that 33 of 734 (4.5%) patients treated with apixaban and 56 of 767 (7.3%) with dalteparin had recurrent VTE as the efficacy outcome (RR 0.49, 95% CI 0.15-1.58, I2 38%). Major bleeding occurred in 25 of 734 patients treated with apixaban (3.4%) and 27 of 767 with dalteparin (3.5%) (RR 1.29, 95% CI 0.31-5.27, I2 59%). Likewise, clinically relevant non-major bleeding occurred in 64 of 734 patients treated with apixaban (8.7%) and 46 of 767 (5.9%) with dalteparin (RR 1.52, 95% CI 1.05-2.19, I2 0%). Conclusions: Apixaban showed a lower risk of recurrent VTE than dalteparin in patients with cancer-associated VTE, but without statistical significance. No statistical significance was observed in clinically relevant major or non-major bleeding.

Risk and timing of venous thromboembolism after surgery for lung cancer: a nationwide cohort study


Ann Thorac Surg. 2023 Oct 25:S0003-4975(23)01073-1. doi: 10.1016/j.athoracsur.2023.10.015. Online ahead of print.

 


ABSTRACT


Doxorubicin (DOX) is a topoisomerase II inhibitor used in cancer therapy. Despite its efficacy, DOX causes serious adverse effects, such as short- and long-term cardiotoxicity. This work aimed to assess the short- and long-term cardiotoxicity of DOX and the role of inflammation and antioxidant defenses on that cardiotoxicity in a mice model. Adult CD-1 male mice received a cumulative dose of 9.0 mg/kg of DOX (2 biweekly intraperitoneal injections (ip), for 3 weeks). One week (1W) or 5 months (5M) after the last DOX administration, the heart was collected. One week after DOX, a significant increase in p62, tumor necrosis factor receptor (TNFR) 2, glutathione peroxidase 1, catalase, inducible nitric oxide synthase (iNOS) cardiac expression, and a trend towards an increase in interleukin (IL)-6, TNFR1, and B-cell lymphoma 2 associated X (Bax) expression was observed. Moreover, DOX induced a decrease on nuclear factor erythroid-2 related factor 2 (Nrf2) cardiac expression. In both 1W and 5M, DOX led to a high density of infiltrating M1 macrophages, but only the 1W-DOX group had a significantly higher number of nuclear factor κB (NF-κB) p65 immunopositive cells. As late effects (5M), an increase in Nrf2, myeloperoxidase, IL-33, tumor necrosis factor-α (TNF-α), superoxide dismutase 2 (SOD2) expression, and a trend towards increased catalase expression were observed. Moreover, B-cell lymphoma 2 (Bcl-2), cyclooxygenase-2 (COX-2), and carbonylated proteins expression decreased, and a trend towards decreased p38 mitogen-activated protein kinase (MAPK) expression were seen. Our study demonstrated that DOX induces adverse outcome pathways related to inflammation and oxidative stress, although activating different time-dependent response mechanisms.

The present review summarizes the beneficial and detrimental roles of reactive oxygen species in myocardial ischemia/reperfusion

 


ABSTRACT


The present review summarizes the beneficial and detrimental roles of reactive oxygen species in myocardial ischemia/reperfusion injury and cardioprotection. In the first part, the continued need for cardioprotection beyond that by rapid reperfusion of acute myocardial infarction is emphasized. Then, pathomechanisms of myocardial ischemia/reperfusion to the myocardium and the coronary circulation and the different modes of cell death in myocardial infarction are characterized. Different mechanical and pharmacological interventions to protect the ischemic/reperfused myocardium in elective percutaneous coronary interventions and coronary artery bypass grafting, in acute myocardial infarction and in cardiotoxicity from cancer therapy are detailed. The second part keeps the focus on ROS providing a comprehensive overview of molecular and cellular mechanisms involved in ischemia/reperfusion injury. Starting from mitochondria as the main sources and targets of ROS in ischemic/reperfused myocardium, a complex network of cellular and extracellular processes is discussed, including relationships with Ca2+ homeostasis, thiol group redox balance, hydrogen sulfide modulation, cross-talk with NAPDH oxidases, exosomes, cytokines and growth factors. While mechanistic insights are needed to improve our current therapeutic approaches, advancements in knowledge of ROS-mediated processes indicate that detrimental facets of oxidative stress are opposed by ROS requirement for physiological and protective reactions. This inevitable contrast is likely to underlie unsuccessful clinical trials and limits the development of novel cardioprotective interventions simply based upon ROS removal.

RESULTS: A total of 415 patients received at least one dose of trial treatment (276 vs. 139). The median PFS was 5.5 months in the aponermin group and 3.1 months

 


ABSTRACT


BACKGROUND: Aponermin, a circularly permuted tumor necrosis factor-related apoptosis-inducing ligand, is a potential death receptor 4/5-targeted antitumour candidate. Previous phase 1/2 studies have demonstrated the efficacy of aponermin in patients with relapsed or refractory multiple myeloma (RRMM). To confirm the superiority of aponermin plus thalidomide and dexamethasone (aponermin group) over placebo plus thalidomide and dexamethasone (placebo group) in RRMM, a randomized, double-blinded, placebo controlled phase 3 trial was performed.


METHODS: Four hundred seventeen patients with RRMM who had previously received at least two regimens were randomly assigned (2:1) to receive aponermin, thalidomide, and dexamethasone or placebo, thalidomide, and dexamethasone. The primary endpoint was progression-free survival (PFS). Key secondary endpoints included overall survival (OS) and overall response rate (ORR).


RESULTS: A total of 415 patients received at least one dose of trial treatment (276 vs. 139). The median PFS was 5.5 months in the aponermin group and 3.1 months in the placebo group (hazard ratio, 0.62; 95% confidence interval [CI], 0.49-0.78; P < 0.001). The median OS was 22.4 months for the aponermin group and 16.4 months for the placebo group (hazard ratio, 0.70; 95% CI, 0.55-0.89; P = 0.003). Significantly higher rates of ORR (30.4% vs. 13.7%, P < 0.001) and very good partial response or better (14.1% vs. 2.2%, P < 0.0001) were achieved in the aponermin group than in the placebo group. Treatment with aponermin caused hepatotoxicity in some patients, as indicated by the elevated alanine transaminase, aspartate transaminase, or lactate dehydrogenase levels (52.2% vs. 24.5%, 51.1% vs. 19.4% and 44.9% vs. 21.6%, respectively), mostly grade 1/2, transient and reversible. The main grade 3/4 adverse events included neutropenia, pneumonia and hyperglycemia. The incidence of serious adverse events was similar between the two groups (40.6% vs. 37.4%). There was no evidence that aponermin leads to hematological toxicity, nephrotoxicity, cardiotoxicity, or secondary tumors.


CONCLUSIONS: Aponermin plus thalidomide and dexamethasone significantly improved PFS, OS and ORR with manageable side effects in RRMM patients who had received at least two prior therapies. These results support the use of aponermin, thalidomide, and dexamethasone as a treatment option for RRMM patients.


TRIAL REGISTRATION: The trial was registered at http://www.chictr.org.cn as ChiCTR-IPR-15006024, 17/11/2014.

ABSTRACT


BACKGROUND: This review focuses on multimodality imaging of cardiotoxicity in cancer patients, with the aim of evaluating the effectiveness of different techniques in detecting and monitoring cardiac changes associated with cancer therapy.


METHODS: Eight studies were included in the review, covering various imaging modalities such as cardiac magnetic resonance imaging, echocardiography, and multigated acquisition scanning.


RESULTS: Cardiac magnetic resonance imaging emerged as the most definitive modality, offering real-time detection, comprehensive assessment of cardiac function, the ability to detect early myocardial changes, and superior detection of cardiotoxicity when compared to the other imaging modalities. The studies also emphasize the importance of parameters such as left ventricular ejection fraction and global longitudinal strain in assessing cardiac function and predicting cardiotoxicity.


CONCLUSION: Due to the common use of HER2 agents and anthracyclines within the breast cancer population, the LVEF as a critical prognostic measurement for assessing heart health and estimating the severity of left-sided cardiac malfunction is a commonly used endpoint. CTRCD rates differed between imaging modalities, with cardiac MRI the most sensitive. The use of multimodal cardiac imaging remains a nuanced area, influenced by local availability, the clinical question at hand, body habits, and medical comorbidities. All of the imaging modalities listed have a role to play in current care; however, focus should be given to increasing the provision of cardiac MRI for breast cancer patients in the future to optimize the detection of CTRCD and patient outcomes thereafter.

BACKGROUND AND AIMS: One of the most common hemoglobinopathies globally related to blood transfusion and iron overload in the body

 


ABSTRACT


BACKGROUND AND AIMS: One of the most common hemoglobinopathies globally related to blood transfusion and iron overload in the body is thalassemia syndrome. Increasing ferritin levels can cause severe damage to the patient's body organs. This study aims to evaluate the complications of iron overload on vital body organs in patients with transfusion-dependent beta-thalassemia.


METHODS: This descriptive cross-sectional study was performed in Iran University of Medical Sciences Hospitals on patients with a beta-thalassemia major with frequent blood transfusions. To evaluate the effect of iron overload on vital body organs, hematologic and blood analysis, echocardiography with measurement of pulmonary artery pressure (PAP) and ejection fraction (EF) tests, bone densitometry, and audiometric tests were performed for all patients.


RESULTS: Of the 1010 patients participating in this study, 497 (49%) were males, 513 were (51%) females aged 5-74 years, and the majority of participants (85%) were over 20 years old. This study demonstrated that increasing ferritin levels had no notable correlation with sex, cholesterol, low-density lipoprotein, parathyroid hormone, T4, and aspartate aminotransferase. However, elevating ferritin levels had significant correlations with increasing triglyceride, phosphorus, thyroid stimulating hormone, alkaline phosphatase, alanine transaminase, and PAP levels, age, hearing disorders, splenectomy, osteoporosis, and decreasing high-density lipoprotein, body mass index, calcium, and EF levels.


CONCLUSION: Improvement in beta-thalassemia patients' survival and quality of life can be due to multidisciplinary care in a comprehensive unit through regular follow-up and early complication detection.

BACKGROUND: With population aging, the prevalence of both cancer and atrial fibrillation (AF) have increased. However, there is scarce epidemiological data concerning the comorbid state of cancer and AF in low- and middle-income countries, including China.


OBJECTIVE: We aimed to evaluate the site-, sex-, and age-specific profiles of cancer and AF comorbidities in Chinese populations.


METHODS: Data from the Shanghai Municipal Health Commission database between 2015 and 2020 were screened, covering all medical records of Shanghai residents with medical insurance. Site-specific cancer profiles were evaluated for the population with AF relative to the age- and sex-adjusted population of residents without AF. The sex distribution and peak age of cancer diagnosis were also assessed.


RESULTS: A total of 25,964,447 adult patients were screened. Among them, 22,185 patients presented cancers comorbid with AF (median 77, IQR 67-82 years of age; men: n=13,631, 61.44%), while 839,864 presented cancers without AF (median 67, IQR 57-72 years of age; men: n=419,020, 49.89%), thus yielding a higher cancer prevalence among residents with AF (8.27%) than among those without AF (6.05%; P<.001).


CONCLUSIONS: Patients with AF are associated with increased prevalence, heightened male predominance, and younger peak age of cancer. Further studies are needed to determine whether early screening of specific cancers is cost-effective and beneficial for patients with AF.

ABSTRACT


Cancer and cardiovascular disorders are known as the two main leading causes of mortality worldwide. Cardiotoxicity is a critical and common adverse effect of cancer-related chemotherapy. Chemotherapy-induced cardiotoxicity has been associated with various cancer treatments, such as anthracyclines, immune checkpoint inhibitors, and kinase inhibitors. Different methods have been reported for the management of chemotherapy-induced cardiotoxicity. In this regard, sodium-glucose cotransporter-2 inhibitors (SGLT2i), a class of antidiabetic agents, have recently been applied to manage heart failure patients. Further, SGLT2i drugs such as EMPA exert protective cardiac and systemic effects. Moreover, it can reduce inflammation through the mediation of major inflammatory components, such as Nucleotide-binding domain-like receptor protein 3 (NLRP3) inflammasomes, Adenosine 5'-monophosphate-activated protein kinase (AMPK), and c-Jun N-terminal kinase (JNK) pathways, Signal transducer and activator of transcription (STAT), and overall decreasing transcription of proinflammatory cytokines. The clinical outcome of EMPA administration is related to improving cardiovascular risk factors, including body weight, lipid profile, blood pressure, and arterial stiffness. Intriguingly, SGLT2 suppressors can regulate microglia-driven hyperinflammation affecting neurological and cardiovascular disorders. In this review, we discuss the protective effects of EMPA in chemotherapy-induced cardiotoxicity from molecular, immunological, and neuroimmunological aspects to preclinical and clinical outcomes.

BACKGROUND: Doxorubicin (DOX)-induced cardiotoxicity is an important cause of poor prognosis in cancer patients treated with DOX

 


ABSTRACT


BACKGROUND: Doxorubicin (DOX)-induced cardiotoxicity is an important cause of poor prognosis in cancer patients treated with DOX. Angiotensin IV (Ang IV) has multiple protective effects against cardiovascular diseases, including diabetic cardiomyopathy and myocardial infarction, but its role in DOX-induced cardiotoxicity is currently unclear. In this study, we investigated the effects of Ang IV on DOX-induced cardiotoxicity.


METHODS: The viability of primary cardiomyocytes was measured by Cell Counting Kit-8 assays and Hoechst 33342/propidium iodide staining in vitro. ELISAs (serum cTnT and CK-MB) and echocardiography were performed to assess myocardial injury and cardiac function in vivo. Phalloidin staining, haematoxylin and eosin staining and wheat germ agglutinin staining were conducted to detect cardiomyocyte atrophy. We also performed C11 BODIPY staining, measured the levels of Ptgs2 and malondialdehyde and detected the concentrations of ferrous ions, glutathione and oxidized glutathione to indicate ferroptosis.


RESULTS: Ang IV not only attenuated DOX-induced atrophy and cardiomyocyte injury in vitro but also alleviated myocardial injury and improved cardiac function in DOX-treated mice in vivo. Moreover, Ang IV reversed DOX-induced downregulation of glutathione peroxidase 4 (GPX4) and inhibited ferroptosis both in vitro and in vivo. Knockdown of GPX4 by siRNA abolished the cardioprotective effects of Ang IV. Furthermore, Ang IV increased GPX4 levels and ameliorated ferroptosis in RAS-selective lethal 3-treated primary cardiomyocytes.


CONCLUSIONS: Ang IV ameliorates DOX-induced cardiotoxicity by upregulating GPX4 and inhibiting ferroptosis. Ang IV may be a promising candidate to protect against DOX-induced cardiotoxicity in the future.

ABSTRACT


A 75-year-old man underwent chemoradiotherapy for advanced esophageal cancer. After nine years, he was hospitalized for left pyothorax. Consequently, the patient underwent drainage and window opening surgery. He experienced cardiopulmonary arrest but was resuscitated. Based on cardiac catheterization data, the patient was diagnosed with constrictive pericarditis. Unfortunately, extracorporeal circulation did not improve his condition, and he ultimately died. An autopsy revealed adhesion between the pericardium and pleura, especially the pericardium in contact with the left thoracic cavity, which was markedly thickened. This suggests that constrictive pericarditis, a latent complication of chemoradiotherapy, is aggravated by pyothorax.

ABSTRACT


INTRODUCTION: Radiotherapy has significantly improved cancer survival rates, but it also comes with certain unavoidable complications. Breast and thoracic irradiation, for instance, can unintentionally expose the heart to radiation, leading to damage at the cellular level within the myocardial structures. Detecting and monitoring radiation-induced heart disease early on is crucial, and several radionuclide imaging techniques have shown promise in this regard.


METHOD: In this 10-year review, we aimed to identify nuclear medicine imaging modalities that can effectively detect early cardiotoxicity following radiation therapy. Through a systematic search on PubMed, we selected nineteen relevant studies based on predefined criteria.


RESULTS: The data suggest that incidental irradiation of the heart during breast or thoracic radiotherapy can cause early metabolic and perfusion changes. Nuclear imaging plays a prominent role in detecting these subclinical effects, which could potentially serve as predictors of late cardiac complications.


DISCUSSION: However, further studies with larger populations, longer follow-up periods, and specific heart dosimetric data are needed to better understand the relationship between early detection of cardiac abnormalities and radiation-induced heart disease.
