[Chemotherapy for colorectal cancers].
Colorectal Cancer (CRC) is the most frequent digestive cancer in France and a major public health problem. The benefits of adjuvant chemotherapy after curative resection of Stage III CRC has been clearly demonstrated. For metastatic CRC, palliative chemotherapy allows an improvement in survival duration and quality of life compared with symptomatic treatment. 5-FU/Leucovorin chemotherapy (Mayo Clinic protocol and LV5FU2) is the standard adjuvant therapy. The addition of irinotecan (FOLFIRI) or oxyplatin (FOLFOX) to this regimen may improve response in palliative situations. These two regimens have shown their superiority to 5FU/Leucovorin in both tumor response and survival. A good objective response to palliative chemotherapy may allow for a secondary resection of hepatic metastases as part of a multidisciplinary approach. Current studies aim to define: 1) optimal treatment strategies (which drug protocols? in what order?) as they apply to tumor spread, drug toxicity profiles, the general state of the patient, and the desired therapeutic effect; 2) evaluation of new drugs and novel therapeutic approaches. Despite notable progress, the prognosis still remains grim with a survival of only 40% at 5 years. Any improvement in results will require not only an improvement in chemotherapy but also an improvement in methods of early diagnosis (systematic mass screening) which would permit the diagnosis of CRC at earlier stages where curative resection is feasible.
