Adjuvant chemotherapy for Dukes B2 and C colon cancer combining 5-fluorouracil and folinic acid with or without carboplatin. Feasibility and comparison between standard and chronomodulated deliveries

Thirty-seven patients operated from a Dukes B2-C colon cancer were randomised to receive as adjuvant infusional chemotherapy, nine 5 FU and folinic acid courses with or without carboplatin, as standard (de Gramont; 2 days every 2 weeks) or chronomodulated administration (4 days every 2 weeks). The overall tolerance was judged excellent with less than 7% courses with dose-adaptations. The two carboplatin arms presented an enhanced haernatological toxicity, while some more cutaneous toxicity was observed in the chronomodulated arm with the three drugs. (c) 2005 Elsevier SAS.
