  • 64 Background: Congestive heart failure (CHF) is among the most serious cardiovascular side effects of targeted agents (TA) impacting the clinical outcomes (including survival) of cancer patients on this therapy. Although clinical trials have reported this toxicity, often sample sizes are small and systemic evaluations are lacking. The objective of this study is to estimate risk and severity of CHF due to selected TAs. Methods: We identified 110 English language studies of 26 TA’s approved by the Food and Drug Administration as of November 2013 via MEDLINE. Of those, 8 studies including nearly 8000 patients provided TA-related data on the incidence and severity of CHF. Using meta-analytic methods, we calculated the relative risks of CHF, adjusting for sample size using the inverse variance technique. For each TA, we also determined the number needed to harm. Results: See table. Conclusions: In 5 studies including more than 7,000 patients, trastuzumab showed significantly greater risk of CHF. For every 9 patients treated with trastuzumab, there was 1 additional case of CHF compared to control regimens. A careful patient selection before therapy and early detection of CHF by judicious monitoring of patients on this therapy may prevent serious complications and allow maintenance of cancer treatment.
