Pharma-clinics. Comment je traite... II. Approche thérapeutique du cancer colorectal métastatique

Since its introduction in 1953, 5-fluorouracil based chemotherapy remained the standard treatment in advanced colorectal cancer. Continuous infusion or biochemical modulation by folinic acid enhanced the therapeutic efficacy of this agent. Quality of life is limited by the toxicity of these regimens as well as by the frequent visits to the hospital during each cycle. Raltitrexed, a thymidylate synthase inhibitor, offers similar antitumoral activity together with a tolerability in comparison to standard 5-fluorouracil based chemotherapy and its simple dosage schedule also contributes to better quality of life. New chemotherapeutic agents are currently in development for the treatment of patients refractory to 5-fluorouracil. Irinotecan and oxaliplatin demonstrate promising activity.
