ABSTRACT

Safety pharmacology is an essential part of drug development aiming to identify, evaluate and investigate undesirable pharmacodynamic properties of a drug primarily prior to clinical trials. In particular, cardiovascular adverse drug reactions (ADR) have halted many drug development programs. Safety pharmacology has successfully implemented a screening strategy to detect cardiovascular liabilities, but there is room for further refinement. In this setting, we present the INSPIRE project, a European Training Network in safety pharmacology for Early Stage Researchers (ESRs), funded by the European Commission's H2020-MSCA-ITN programme. INSPIRE has recruited 15 ESR fellows that will conduct an individual PhD-research project for a period of 36 months. INSPIRE aims to be complementary to ongoing research initiatives. With this as a goal, an inventory of collaborative research initiatives in safety pharmacology was created and the ESR projects have been designed to be complementary to this roadmap. Overall, INSPIRE aims to improve cardiovascular safety evaluation, either by investigating technological innovations or by adding mechanistic insight in emerging safety concerns, as observed in the field of cardio-oncology. Finally, in addition to its hands-on research pillar, INSPIRE will organize a number of summer schools and workshops that will be open to the wider community as well. In summary, INSPIRE aims to foster both research and training in safety pharmacology and hopes to inspire the future generation of safety scientists.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) for unresectable peritoneal metastasis from gastric cancer

Alyami M, et al. Eur J Surg Oncol 2020.

ABSTRACT

BACKGROUND: PIPAC is a recent approach with promising results for patients with peritoneal metastasis (PM). We aimed to evaluate survival and postoperative outcome of patients with unresectable PM from gastric origin treated with chemotherapy and PIPAC.

METHODS: A retrospective analysis of a prospective maintained PIPAC database was queried for all patients diagnosed with unresectable PM from gastric cancer who underwent PIPAC before 2018. PIPAC with Cisplatin 7.5 mg/m2 and doxorubicin 1.5 mg/m2 were given for 30 min at 6-week intervals. Outcome criteria were overall survival and adverse events according to (CTCAE) version4.0.

RESULTS: One hundred Sixty-three PIPAC were done in 42 consecutive patients. Twenty-two (52%) of the patients were female. Signet-ring cells were observed in 33/42 patients (78.6%). At the first PIPAC, median age was 51.5 years (32-74). Median PCI was 17 (1-39). Twenty (47.6%) patients underwent more than 2 lines of pre-PIPAC chemotherapy. All patients had systemic chemotherapy alternating with PIPAC. Median consecutive PIPAC procedures were 3 (1-12). Overall and major complications (CTCAE - III, IV) occurred in 10 (6.1%) and 5 procedures (3.1%), respectively. Two patients (4.7%) died within 30 days of a PIPAC procedure, one related to small bowel obstruction and a pulmonary embolism for the other. Overall Survival was 19.1 months. Six (14.3%) patients became resectable during treatment and underwent curative intent CRS and HIPEC.

CONCLUSIONS: PIPAC with low-dose cisplatin and doxorubicin is safe and feasible in association with systemic chemotherapy for gastric PM. Survival data are encouraging and justify further clinical studies in this indication.

Prevention and treatment of venous thromboembolism in cancer patients

Spehlmann ME, et al. Herz 2020 - Review.

ABSTRACT

Deep vein thrombosis and pulmonary artery embolism are common and serious concomitant diseases in patients with cancer. The prophylaxis and therapy of such venous thromboembolic events (VTE) in oncology have so far been achieved with low-molecular-weight heparins. An increasing number of studies show evidence of the use of direct oral anticoagulants. However, since none of the possible options were shown to have a clear advantage in all patients, the individual decision to use a drug should be made depending on its effectiveness in preventing VTE, the risk of bleeding, the nature of the cancer, the interactions with other medications, the route of administration, and finally the cost of treatment.

Cardioprotective Strategies to Prevent Cancer Treatment-Related Cardiovascular Toxicity: a Review

Upshaw JN. Curr Oncol Rep 2020 - Review.

ABSTRACT

PURPOSE OF REVIEW: Patients with cancer have an elevated risk of cardiovascular disease. This review describes the cardiovascular risks of different cancer therapies and the evidence for cardioprotective strategies.

RECENT FINDINGS: Recent studies have provided additional support for the safety and efficacy of dexrazoxane and liposomal anthracycline formulations in certain high-risk patients receiving anthracyclines and for neurohormonal antagonist therapy in patients with breast cancer receiving sequential anthracyclines and trastuzumab. Ongoing studies are exploring the benefit of: (1) statins for anthracycline cardioprotection; (2) strict blood pressure control during vascular endothelial growth factor inhibitor treatment and; (3) dexrazoxane on long-term cardiac outcomes in pediatric populations. To date, there are no evidence-based cardioprotective strategies specifically for radiation-related heart and vascular disease, immunotherapy myocarditis, fluoropyrimidine cardiotoxicity, vascular endothelial growth factor inhibitor-related hypertension, BCR-Abl multikinase inhibitor vascular disease, and other established and emerging cancer therapeutics with cardiovascular effects. Current evidence supports specific cardioprotective strategies for high risk patients receiving anthracyclines or sequential anthracycline-trastuzumab therapy; however, major evidence gaps exist.

Venous thromboembolism after adult thymus or thymic tumor resection: A single-center experience

Yang X, et al. Thorac Cancer 2020.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is a common postoperative complication. Previous studies have shown that the VTE incidence after major thoracic surgery is high. However, there have been no exclusive data after thymectomy thus far. To investigate the incidence of postoperative VTE, we conducted a single-center, prospective cohort study.

METHODS: Patients who underwent thymectomy between December 2017 and January 2020 were enrolled. None of the patients received any prophylaxis perioperatively. Subjects were risk stratified into groups of low risk (0-4), moderate risk (5-8), and high risk (≥9). Occurrence of VTE events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), were identified by imaging.

RESULTS: There were 192 patients who underwent thymectomy enrolled into the study. The overall VTE incidence was 8.9%. All the patients were diagnosed with DVT, and none were diagnosed with PE. The VTE incidence was 4.6% in patients with benign thymic diseases and 14.5% with malignant diseases. The VTE incidence was 4.7% in patients undergoing thoracoscopic surgery and 22.7% undergoing median sternotomy. The VTE incidence increased with Caprini score. Scores in the low, moderate, and high risk groups were associated with a VTE incidence of 0%, 10.3% and 37.5%, respectively. In patients with thymic malignancy, the VTE incidence in the moderate and high risk groups were 8.8% and 31.8%, respectively.

CONCLUSIONS: VTE occurred frequently in patients after thymectomy without VTE prophylaxis. The median sternotomy procedure and malignant tumor may be the major risk factors for the development of VTE. Aggressive VTE screening/treatment protocols should be implemented in patents after thymectomy.

Establishing an oncocardiology service

Lehmann LH and Totzeck M. Herz 2020 - Review.

ABSTRACT

Oncocardiology is an emerging field in cardiovascular healthcare. Besides establishing surveillance and follow-up strategies for cancer patients, it will be essential to set up specialized oncocardiology services. However, there is a lack of clinical studies to give evidence-based recommendations regarding cardiological diagnostic and therapeutic approaches for cancer patients. An oncocardiology service is a patient-centered structure that aims to integrate research and interdisciplinary patient care to bridge this gap. We discuss the current challenges in developing an oncocardiology service and review the literature on this topic. We further provide an overview of the essential diagnostic tools and upcoming ethical issues to be considered in the management of oncology patients.

Positron emission tomography imaging in cardiovascular disease

Tarkin JM, et al. Heart 2020 - Review.

ABSTRACT

Positron emission tomography (PET) imaging is useful in cardiovascular disease across several areas, from assessment of myocardial perfusion and viability, to highlighting atherosclerotic plaque activity and measuring the extent of cardiac innervation in heart failure. Other important roles of PET have emerged in prosthetic valve endocarditis, implanted device infection, infiltrative cardiomyopathies, aortic stenosis and cardio-oncology. Advances in scanner technology, including hybrid PET/MRI and total body PET imaging, as well as the development of novel PET tracers and cardiac-specific postprocessing techniques using artificial intelligence will undoubtedly continue to progress the field.

Echocardiography and biomarkers for the diagnosis of cardiotoxicity

Berliner D, et al. Herz 2020 - Review.

ABSTRACT

As a result of better treatment options for malignant cancer, the cardiovascular side effects of such therapies have increasingly come into focus in recent years. The new cardiological subspecialty of oncocardiology is developing strategies to prevent and/or detect those effects early in order to treat them in a timely and adequate manner. The diagnosis of cardiotoxic effects is based mainly on imaging and specific biomarkers. Echocardiography has become the main imaging technique due to its wide availability. In addition to quantitative determination of left ventricular function using two-dimensional methods, three-dimensional methods offer better precision and less variability in the detection of cardiac dysfunction. Furthermore, the analysis of the global longitudinal strain (GLS) reveals even subtle changes in left ventricular function and thus detects very early damage before left ventricular ejection fraction drops. Various biomarkers have been tested recently for their potential to detect cardiotoxicity. Cardiac troponins are currently the best investigated biomarkers and certainly have the highest impact. Due to contradicting results, the importance of natriuretic peptides has not yet been conclusively clarified. Results for myeloperoxidase are promising, as are the results for circulating microRNAs, which still mainly derive from experimental data. In this context, further studies still need to show the value of these in everyday clinical practice.

Effectiveness and Safety of Apixaban and Rivaroxaban for Acute Venous Thromboembolism Therapy in Patients with Extremes in Body Weight (ClinicalTrials.gov: NCT03504007)

Wysokinski WE, et al. Eur J Haematol 2020.

ABSTRACT

OBJECTIVES: To investigate the association of extremes in body weight EBW and outcomes in patients with acute venous thromboembolism (VTE), recurrent VTE, major bleeding, and clinically relevant non-major bleeding were compared between patients with body weight <60120 kg.

METHODS: Consecutive patients enrolled in the Mayo Clinic VTE Registry (03/28/2013-8/31/2019) with acute VTE were followed prospectively. Patient status was assessed in person, by mailing a written questionnaire, or by a scripted phone interview.

RESULTS: Amongst 2577 patients with the weight ranging from 27.0 kg to 263.2 kg, 2123 (82%) had a bodyweight between 60 - 120 kg, 223 (8.7%) bodyweight <60120 kg. Patients with bodyweight <60kg120kg and cancer on rivaroxaban had higher VTE recurrence compared to bodyweight 60-120kg group (p=0.01).

CONCLUSIONS: Treatment of acute VTE is associated with a higher incidence of bleeding in patients with bodyweight <60kg.120kg on rivaroxaban.
