Clinical characteristics and risk factors of hand-foot syndrome were investigated in patients who received capecitabine-containing chemotherapy. Toxicity data were analyzed from 179 patients in 4 prospective clinical trials testing docetaxel/capecitabine/cisplatin in stomach cancer, capecitabine/cisplatin in biliary or stomach cancer, and vinorelbine/capecitabine in breast cancer. Hand-foot syndrome was reported in 116/179 (64.8%) of patients, with grade 3 hand-foot syndrome in 8/179 (4.5%). Hand-foot syndrome first developed within the first 3 chemotherapy cycles in 100/116 (86.2%) patients, with the median onset for all 3 treatment regimens occurring during cycle 2. Because severe reactions were rare, hand-foot syndrome was not a major factor influencing treatment schedule. Risk factor analyses showed that combined use of docetaxel and preceding chemotherapy-related stomatitis were significant risk factors for the development of hand-foot syndrome. Our results suggest that a combined treatment agent and a patient's susceptibility to chemotherapy-related toxicity may increase the risk of capecitabine-induced hand-foot syndrome.
