Study of the Postoperative Adjuvant Chemotherapy with UFT/LV or Capecitabine for Stage III Colorectal Cancer]

This study sought to compare UFT/LV with capecitabine as adjuvant chemotherapy for the treatment of stage III colorectal cancer.We conducted a retrospective analysis of patients with Stage III colorectal cancer who under- went surgical resection, except low rectal resections(Rb), followed by adjuvant chemotherapy with UFT/LV or capecitabine between 2007 and 2009, and evaluated background factors, adverse event profiles, disease free survival(DFS), and overall survival(OS).The analysis included 39 patients treated with UFT/LV and 29 with capecitabine, with no significant differences observed between the groups in terms of gender, age, or disease Stage. The most common adverse events were gastrointestinal symptoms in the UFT/LV group, and hand-foot syndrome in the capecitabine group. The 3-year DFS was 69.2 and 64.7% in the UFT/LV and capecitabine groups respectively, and 3-year OS was 89.7 and 92.7% in the UFT/LV and capecitabine groups respectively, indicating no significant differences between the groups.There were no marked differences in treatment outcomes with UFT/LV or capecitabine when they were used as adjuvant chemotherapy for Stage III colorectal cancer, suggesting that a choice between these 2 agents can be made on the basis of avoiding adverse events.
