Cancer chemotherapy and cardiovascular risks: is capecitabine-induced hypertriglyceridemia a rare adverse effect?

Abstract

Capecitabine is an oral fluoropyrimidine which is transformed to 5-Fluorouracil inside tumor cells, where it achieves high drug concentrations. Capecitabine is an active drug diffusely utilized in the treatment of various types of tumors, such as breast, colorectal, gastric, head and neck carcinoma. In our experience, capecitabine-induced hypertriglyceridemia does not seem to be a rare adverse effect as it is observed in 10% of treated patients. It is necessary to monitor the lipidic profile of patients treated with capecitabine also in consideration of the frequent presence of comorbidities in cancer populations, the concomitant toxicity related to other drugs used in combination regimens, and cardiovascular effects characteristic of biological target therapy.
