Fluoropyrimidine Cardiotoxicity: Time for a Contemporaneous Appraisal.

ABSTRACT: INTRODUCTION:Fluoropyrimidines (FPDs) are a fundamental component of many chemotherapy regimens. Cardiotoxic adverse events (AEs) such as angina, ischemia, arrhythmias, and cardiomyopathy associated with 5-fluorouracil (5-FU) and capecitabine (CAPE) have been sparingly described in studies, primarily through case reports. Data from the 1990s revealed an estimated incidence of 0.5% to 19%, with cardiovascular fatalities occurring in ?28%. The current use of FPDs includes multiple dosing regimens, oral or intravenous delivery, and administration with additional cardiotoxic therapies. As such, it is imperative to better define the cardiotoxicity risk in the modern treatment era. We comprehensively evaluated the incidence, prevalence, and ascertainment of cardiovascular risk factors and disease within ECOG-ACRIN (Eastern Cooperative Group Cancer Research Group - American College of Radiology Imaging Network) Cancer Research Group clinical trials incorporating 5-FU and CAPE. MATERIALS AND METHODS:Case report forms and clinical study reports from the ECOG-ACRIN Cancer Research Group database of phase II and III clinical trials incorporating 5-FU and CAPE were evaluated. A total of 16 trials from 2002 to 2017 were identified that had used bolus 5-FU (n = 1), continuous infusion 5-FU (n = 10) or CAPE (n = 5). RESULTS:A history of cardiovascular disease was variably defined and was an exclusion criterion in 13 of the 16 studies (81%). The baseline risk factors and history of cardiac disease were specifically collected in only 3 studies (19%). All studies collected cardiovascular AEs using the Common Terminology Criteria for Adverse Events version available at the time of the study. Fewer than half (7 of 16; 44%) of the study case report forms had also specifically requested information on cardiac ischemia/infarction. In the 12 completed studies with clinical study reports, the following AEs were reported: dyspnea, ?16%; arrhythmias, ?6%; and angina, ischemia, and elevated troponin, ?5%. Some trials only recorded cardiac AEs that were possibly associated with the novel drug being studied and not those attributed to the standard of care in the 5-FU/CAPE arm, further decreasing the numerical incidence. CONCLUSION:Inconsistent clinical trial reporting of cardiac AEs precluded accurate and precise delineation of the epidemiology of FPD-related cardiovascular AEs. Prospective knowledge of the definition and natural history will lead to the development of risk factor stratification and prechemotherapy interventions to reduce or prevent cardiotoxicity. We propose that the prospective collection of baseline cardiac data and prespecified cardiac endpoints are necessary to fully understand the incidence and cardiac risk of FDPs.

Project description:Fluoropyrimidines (FP) are the backbone chemotherapy in colorectal cancer (CRC) treatment; however, their use is associated with cardiotoxicity, which is underreported. In the present study, we aimed to prospectively determining the incidence rates and related risk factors of FP-induced cardiotoxicity (FIC) in CRC patients and at identifying predictive biomarkers. One hundred and twenty-nine consecutive previously untreated CRC patients underwent active cardiological monitoring, including 5-items simplified questionnaire on symptoms, electrocardiogram (ECG) and plasma sample collection during FP chemotherapy. FIC was defined as the presence of ECG alterations and/or the arising of at least one symptom of chest pain, dyspnoea, palpitations or syncope. The primary objective was the evaluation of FIC incidence. Secondary objectives were the correlation of FIC with well-known cardiological risk factors and the identification of circulating biomarkers (serum levels of TnI, proBNP; miRNA analysis) as predictors of FIC. Twenty out of 129 (15.5%) patients experienced FIC. The most common symptoms were dyspnoea (60%) and chest pain (40%), while only 15% of patients presented ECG alterations, including one acute myocardial infarction. Retreatment with FP was attempted in 90% of patients with a favourable outcome. Despite 48% of patients having cardiological comorbidities, we did not observe an increased FIC in this subgroup. Only the subgroup of females with the habit of alcohol consumption showed an increased risk of FIC. None of the circulating biomarkers evaluated demonstrated a clinical utility as FIC predictors. FIC can be an unexpected, life-threatening adverse event that can limit the subsequent treatment choices in CRC patients. In this prospective study, well-known cardiological comorbidities were not related to higher FIC risk and circulating biomarkers predictive of toxicity could not be found. With careful monitoring, mainly based on symptoms, almost all patients completed the FP treatment.

In the present study, it was aimed to prospectively determine the incidence rates and related risk factors of FP‑induced cardiotoxicity (FIC) in CRC patients and at identifying predictive biomarkers. A total of 129 consecutive previously untreated CRC patients underwent active cardiological monitoring, including 5‑items simplified questionnaire on symptoms, electrocardiogram (ECG) and plasma sample collection during FP chemotherapy.
