Importance: The comorbid conditions of patients with cancer affect treatment decisions, which in turn affect survival and health-related quality-of-life outcomes. Comparative effectiveness research studies must account for these conditions via medical record abstraction or patient report. Objective: To examine the agreement between medical records and patient reports in assessing comorbidities. Design, Setting, and Participants: Patient-reported information and medical records were prospectively collected as part of the North Carolina Prostate Cancer Comparative Effectiveness & Survivorship Study, a population-based cohort of 881 patients with newly diagnosed localized prostate cancer enrolled in the North Carolina Central Cancer Registry from January 1, 2011, through June 30, 2013...

Tyrosine kinase inhibitors (TKIs), despite their efficacy as anticancer therapeutics, are associated with cardiovascular side effects ranging from induced arrhythmias to heart failure. We used human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), generated from 11 healthy individuals and 2 patients receiving cancer treatment, to screen U.S. Food and Drug Administration-approved TKIs for cardiotoxicities by measuring alterations in cardiomyocyte viability, contractility, electrophysiology, calcium handling, and signaling...

Pulmonary embolism (PE) is a common, potentially fatal thrombotic disease. Atrial fibrillation (AF), the most common arrhythmia, may also lead to thromboembolic complications. Although initially appearing as distinct entities, PE and AF may coexist. The direction and extent of this association has not been well characterized. We performed a search of PubMed, Scopus, and the Cochrane Database of Systematic Reviews for publications that reported coexisting AF in patients with PE, or vice versa, to provide a systematic overview of pathophysiological and epidemiological aspects of this association (last search: October 13, 2016)...

REVIEW
Alexander B Nicholson, Graeme R Watson, Sheena Derry, Philip J Wiffen
BACKGROUND: This is an updated review originally published in 2004 and first updated in 2007. This version includes substantial changes to bring it in line with current methodological requirements. Methadone is a synthetic opioid that presents some challenges in dose titration and is recognised to cause potentially fatal arrhythmias in some patients. It does have a place in therapy for people who cannot tolerate other opioids but should be initiated only by experienced practitioners. This review is one of a suite of reviews on opioids for cancer pain...

Cardenolides are cardiac glycosides, mostly obtained from natural sources. They are well known for their inhibitory action on the Na,K-ATPase, an effect that regulates cardiovascular alterations such as congestive heart failure and atrial arrhythmias. In recent years, they have also sparked new interest in their anticancer potential. In the present study, the cytotoxic effects of the natural cardenolide convallatoxin (CON) were evaluated on non-small cell lung cancer (A549 cells). It was found that CON induced cytostatic and cytotoxic effects in A549 cells, showing essentially apoptotic cell death, as detected by annexin V-propidium iodide double-staining, as well as changes in cell form...

Anthracycline-based cardiotoxicity is concerning for women with breast cancer and portends a dose-dependent risk of developing left ventricular dysfunction. Overall, the prevalence of heart failure (HF) is ≈2% of the total US population; however, BRCA-deficient mice have shown increased HF. We evaluated for the inherent risk of HF in women with BRCA mutations to determine whether treatment with anthracycline-based therapy increased this risk. We obtained results on BRCA mutation carriers regarding cancer treatment and HF, identified through the BRCA patient advocacy organization Facing Our Risk for Cancer Empowered (FORCE) and the Moffittbased Inherited Cancer Registry...

The numbers of survivors of cancer have increased as a consequence of advances in chemotherapy; however, the side effects of cancer treatment have become increasingly more important. The most frequent side effects include cardiovascular complications, which can lead to acute and delayed morbidity and mortality, often many years later. The discipline of cardio-oncology deals with the prevention, diagnostics and treatment of cardiovascular diseases caused by cancer therapy. The most important cardiovascular side effects of cytostatic therapy are heart failure due to myocardial dysfunction (cardiotoxicity), coronary artery disease, valvular disease and ventricular arrhythmia as a result of QT extension...
