Gemcitabine-Induced Cardiotoxicity in Patients Receiving Adjuvant Chemotherapy for Pancreatic Cancer: A Case Series

Gemcitabine is not considered a cardiotoxic agent generally; so far only very few case reports have been reported in the literature on different aspects of cardiac side effects. Here we report a case series of 3 patients who developed congestive cardiac failure, when treated with gemcitabine monotherapy in the adjuvant setting for pancreatic cancers. Adjuvant chemotherapy with gemcitabine has been the standard of care for pancreatic cancer patients after successful surgery since the results of the CONKO-001 and ESPAC3 study were published. Gemcitabine was administered on days 1, 8, and 15 of a 28-day cycle at 1,000 mg/m². All 3 patients developed symptoms suggestive of cardiac failure with a drop in ejection fraction on echocardiography, and responded to conservative treatment for heart failure after withdrawal of gemcitabine therapy. Early withdrawal of gemcitabine chemotherapy is recommended in addition to a need for studies required to evaluate the mechanism of cardiotoxicity. As per available literature, patients with diabetes and having received a total dose greater than 15,000 mg/m² are generally at a higher risk and require close surveillance.
