Sumario:BACKGROUND: Capecitabine monotherapy is a treatment option for selected patients with metastatic colorectal cancer (mCRC) and is administered to up to 17% of patients. Data are limited with regard to adverse events and dosing practices associated with capecitabine monotherapy in real-world situations. OBJECTIVES: The aim of this study was to provide real-world data on adverse event rates and dose adjustments/discontinuations associated with capecitabine monotherapy in patients with mCRC. METHODS: This retrospective study analyzed data from CRC patients scheduled to receive up to eight planned cycles of capecitabine monotherapy between 2009 and 2013 at a single large community hospital in The Netherlands. Data on adverse events (hand-foot syndrome [HFS], gastrointestinal (GI) events, hematological adverse events, and cardiotoxicity), as well as relative dose intensities (RDIs), dose reductions, and discontinuations, were evaluated. RESULTS: Data from 86 patients (45 females; mean age at the start of treatment, 69 years) were included. A total of 46.5% of patients experienced HFS and 44.2% experienced a GI event at some time during treatment. Hematological events and cardiotoxicity were rare. Most patients (77%) started at below the recommended dose, and patients at the lowest dose also had the lowest median RDIs. Dose reductions and discontinuations occurred in 15–25% of patients who experienced HFS or GI event over the course of eight cycles. CONCLUSIONS: HFS and GI events were very common in patients treated with capecitabine monotherapy in a real-world clinical setting. Most patients started treatment at below the recommended dose, and 15–25% of patients who had HFS or a GI event had a dose reduction or discontinuation.
