5-Fluorouracil plus leucovorin is an effective adjuvant chemotherapy in curatively resected stage III colon cancer: long-term follow-up results of the adjCCA-01 trial.

BACKGROUND: Adjuvant postoperative treatment with 5-fluorouracil (5-FU) and leucovorin in curatively resected stage III colon cancer significantly reduces the risk of cancer recurrences and improves survival. The impact of 5-FU plus leucovorin on survival and tumor recurrence was analyzed in a long-term follow-up study in comparison with the effects of 5-FU plus levamisole in the prospective multicenter trial adjCCA-01. PATIENTS AND METHODS: Patients with a curatively resected stage III (International Union Against Cancer) colon cancer were stratified according to tumor, node and grading category and randomly assigned to receive one of the two adjuvant treatment schemes: 5-FU 400 mg/m2 body surface area intravenously in the first chemotherapy course, then 450 mg/m2 x 5 days, plus leucovorin 100 mg/m2, 12 cycles (arm A), or 5-FU plus levamisole (Moertel scheme; arm B). RESULTS: Six hundred and eighty (96.9%) of 702 patients enrolled into this study were eligible. To date, 261 patients have died, 117 on arm A and 144 on arm B (P = 0.007). After a median follow-up time of 82 months, the 5-FU plus leucovorin combination significantly improved disease-free survival [79.8 months in arm A versus 69.3 months in arm B (P = 0.012)] and significantly increased median overall survival (88.9 months in arm A versus 78.6 months in arm B; P = 0.003). Adjuvant treatment with 5-FU plus levamisole as well as 5-FU plus leucovorin was generally well tolerated; only a minority of patients experienced grade 3 and 4 toxicities. CONCLUSIONS: After curative resection of a stage III colon cancer, adjuvant treatment with 5-FU plus leucovorin is generally well tolerated. This long-term follow-up study demonstrates that adjuvant treatment with 5-FU plus leucovorin given for 12 cycles is significantly more effective than 5-FU plus levamisole (Moertel scheme) in reducing tumor relapse and improving survival.

Fluorouracil plus leucovorin as effective adjuvant chemotherapy in curatively resected stage III colon cancer: results of the trial adjCCA-01.

PURPOSE: Adjuvant postoperative treatment with fluorouracil (5-FU) and levamisole in curatively resected stage III colon cancer significantly reduces the risk of cancer recurrence and improves survival. Biochemical modulation of 5-FU with leucovorin has resulted in increased remission rates in metastatic colorectal cancer, thus reflecting an increased tumor-cell kill. The impact of 5-FU plus leucovorin on survival and tumor recurrence was analyzed in comparison with the effects of 5-FU plus levamisole in the prospective multicentric trial adjCCA-01. PATIENTS AND METHODS: Patients with a curatively resected International Union Against Cancer stage III colon cancer were stratified according to T, N, and G category and randomly assigned to receive one of the two adjuvant treatment schemes: 5-FU 400 mg/m(2) body-surface area intravenously in the first chemotherapy course, then 450 mg/m(2) x 5 days; 12 cycles, plus leucovorin 100 mg/m(2) (arm A), or 5-FU plus levamisole (Moertel scheme; arm B). RESULTS: Six hundred eighty (96.9%) of 702 patients enrolled onto this study were eligible. After a median follow-up time of 46.5 months, the 5-FU plus leucovorin combination significantly improved disease-free survival (P =.037) and significantly decreased overall mortality (P =.0089) in comparison with 5-FU plus levamisole. In a multivariate proportional hazards model, adjuvant chemotherapy emerged as a significant prognostic factor for survival (P =.0059) and disease-free survival (P =.03). Adjuvant treatment with 5-FU plus levamisole as well as with 5-FU plus leucovorin was generally well tolerated; only a minority of patients experienced grade 3 and 4 toxicities. CONCLUSION: After a curative resection of a stage III colon cancer, adjuvant treatment with 5-FU plus leucovorin is generally well tolerated and significantly more effective than 5-FU plus levamisole in reducing tumor relapse and improving survival.

[Chemotherapy and radiochemotherapy of colorectal cancers: adjuvant and palliative therapeutic procedures].

Palliative treatment in metastatic colorectal carcinoma is primarily based on 5-fluorouracil. The remission rates have been improved by biomodulation and by continuous infusion of 5-FU. Adjuvant treatment for carcinoma of the colon and rectum is used in subgroups of patients in order to improve the results of surgical treatment. After curative resection of a colonic carcinoma with lymph node metastasis (TNM stage III) treatment with levamisole and 5-FU is indicated. As the risk of local failure is increased in carcinoma of the rectum adjuvant pelvic radiation therapy is used, eventually combined with systemic chemotherapy. In order to define the subgroups of patients who might profit by palliative or adjuvant treatment and in order to develop more effective combination therapies patients should be entered into prospective randomized trials.
