Chimiothérapie adjuvante pour le cancer du colon de stades Dukes B2 et C comportant du 5-fluorouracile et de l'acide folinique, avec ou sans carboplatine. Faisabilité et comparaison d'une administration standard à une administration chronomodulée

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 haematological toxicity, while some more cutaneous toxicity was observed in the chronomodulated arm with the three drugs.
