We prospectively evaluated the feasibility of XELOX(oxaliplatin 130 mg/m/(2) on day 1 plus capecitabine 1,000 mg/m(2) twice daily on days 1 to 14 every 3 weeks) for adjuvant treatment in 15 patients with stage III/IV (Japanese classification) colorectal cancer and pathological curability A or B after D2-D3 lymph node dissection. Patients were seen at our institute between September 2009 and January 2012. In the current study, no severe adverse events occurred, including hand-foot syndrome greater than Grade 3, as compared with the MOSAIC, NSABP C-07, and NO16968/XELOXA trials. We confirm that XELOX is a feasible treatment option and discuss the benefits of evaluating the safety and efficacy of XELOX in more patients.
