ABSTRACT

Cancer therapy-related cardiotoxicity has been presenting a major problem in cancer survivors, who constitute a growing population caused by a significant improvement in cancer therapy during the past decades. Although some listing criteria have been defined for these patients, it is still a compelling decision to list patients with a complex cancer anamnesis. We describe herein a childhood cancer survivor after a cancer anamnesis with 2 different malignancies and an end-stage heart failure following chemoradiotherapy who was successfully treated with orthotopic heart transplant.

Using big data to retrospectively validate the COMPASS-CAT risk assessment model: considerations on methodology

Nikolakopoulos I, et al. J Thromb Thrombolysis 2020.

ABSTRACT

External validation is a prerequisite in order for a prediction model to be introduced into clinical practice. Nonetheless, methodologically intact external validation studies are a scarce finding. Utilization of big datasets can help overcome several causes of methodological failure. However, transparent reporting is needed to standardize the methods, assess the risk of bias and synthesize multiple validation studies in order to infer model generalizability. We describe the methodological challenges faced when using multiple big datasets to perform the first retrospective external validation study of the Prospective Comparison of Methods for thromboembolic risk assessment with clinical Perceptions and AwareneSS in real life patients-Cancer Associated Thrombosis (COMPASS-CAT) Risk Assessment Model for predicting venous thromboembolism in patients with cancer. The challenges included choosing the starting point, defining time sensitive variables that serve both as risk factors and outcome variables and using non-research oriented databases to form validated definitions from administrative codes. We also present the structured plan we used so as to overcome those obstacles and reduce bias with the target of producing an external validation study that successfully complies with prediction model reporting guidelines.

INSPIRE: A European training network to Foster research and training in cardiovascular safety pharmacology

Guns PD, et al. J Pharmacol Toxicol Methods 2020.

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.

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.

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.

Pluripotent Stem Cell Modeling of Anticancer Therapy-Induced Cardiotoxicity

Lyra-Leite DM and Burridge PW. Curr Cardiol Rep 2020 - Review.

ABSTRACT

PURPOSE OF REVIEW: In this article, we review the different model systems based on human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) and how they have been applied to identify the cardiotoxic effects of anticancer therapies.

RECENT FINDINGS: Developments on 2D and 3D culture systems enabled the use of hiPSC-CMs as screening platforms for cardiotoxic effects of anticancer therapies such as anthracyclines, monoclonal antibodies, and tyrosine kinase inhibitors. Combined with computational approaches and higher throughput screening technologies, they have also enabled mechanistic studies and the search for cardioprotective strategies. As the population ages and cancer treatments become more effective, the cardiotoxic effects of anticancer drugs become a bigger problem leading to an increased role of cardio-oncology. In the past decade, human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have become an important platform for preclinical drug tests, elucidating mechanisms of action for drugs, and identifying cardioprotective pathways that could be further explored in the development of combined treatments. In this article, we highlight 2D and 3D model systems based on hiPSC-CMs that have been used to study the cardiotoxic effects of anticancer drugs, investigating their mechanisms of action and the potential for patient-specific prediction. We also present some of the important challenges and opportunities in the field, indicating possible future developments and how they could impact the landscape of cardio-oncology.

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.
