Severe Cardiotoxicity in a Patient with Colorectal Cancer Treated with Bevacizumab.
ANTICANCER RESEARCH(2017)
Abstract
Background/Aim: Bevacizumab combined with standard chemotherapeutics has become a choice of treatment for several kinds of cancers. Hypertension, third-degree albuminuria, thrombosis and cardiotoxicity are the reported side-effects of bevacizumab. Among them, cardiotoxicity is a most severe, but rare outcome. We report a case of a 62-year-old female with colorectal carcinoma who was given bevacizumab-containing chemotherapy for more than 20 months and achieved a stable disease during the entire course of treatment. Thereafter, she developed cardiotoxicity including grade 3 hypertension, tricuspid regurgitation, pulmonary hypertension, left ventricular diastolic dysfunction and pericardial effusion, and was discontinued from the regimen with bevacizumab. Conclusion: Although clinically-effective, the severe cardiotoxicity of bevacizumab developed after over 20 courses of treatment prompted us to look for optimal chemotherapy prescription in order to achieve a better clinical outcome.
