Abstract: | PURPOSE: Daily divided dose cisplatin (DDD-P) is used as an efficient modulator of fluorouracil (5-FU), as is leucovorin (LV). We performed a randomized trial to compare the efficacy 5-FU plus DDD-P (DDD-FP) therapy with 5-FU alone in resected colorectal cancer as the adjuvant therapy. METHODS: One hundred and eighty-eight stage II or III colorectal cancer patients were enrolled. Patients were randomly assigned to receive DDD-FP (5-FU, 320 mg/ m(2), daily for 21 days; CDDP, 3.5 mg/m(2) daily for 21 days) followed by oral 5-FU (200 mg/body daily for 2 years) (DDD-FP arm) or oral 5-FU therapy (200 mg/ body daily for 2 years) exclusively (oral 5-FU arm). RESULTS: The 5-year disease-free survival (DFS) rates and the overall survival (OS) rates indicated no significant difference between the two arms. By stratified analysis, in the colon cancer patients, the DFS and the OS for the DDD-FP arm were significantly increased: 93.5% and 95.7% in the DDD-FP arm as compared with 76.9% and 82.2% in the oral 5-FU arm (P = 0.024 and P = 0.038). Regarding adverse effects, grade 3-4 toxicities were not significant in two arms. CONCLUSIONS: DDD-FP followed by oral 5-FU therapy suggested a feasible regimen for patients with resected colon cancer as the adjuvant therapy. |
