[Established data and practical recommendations concerning pre- and postoperative chemotherapy of rectal cancer].

| Abstract |
Adjuvant chemotherapy appears to be active in stage II-III rectal cancers; the NSAPB R01 trial demonstrated a survival advantage for patients receiving chemotherapy using the MOF protocol and 3 meta-analyses are in favor of the efficacy of adjuvant chemotherapy in rectal cancer. Three randomized trials have also demonstrated that combinations of radiation and chemotherapy are superior to surgery alone or adjuvant radiotherapy and demonstrated the major role of systemic chemotherapy combined with radiotherapy. However this efficacy of adjuvant chemotherapy alone or combined with radiation therapy is still debated and specific trials must be conducted to test the value of chemotherapy using more active regimens than those previously tested and taking into account the quality of surgery and radiotherapy; such trials are in progress, especially the trial conducted by the EORTC and the FFCD. The efficacy of neoadjuvant chemotherapy has never been clearly demonstrated, although a combination of radiotherapy and chemotherapy as first-line treatment for locally advanced rectal cancer and in the case of synchronous metastasis seems to facilitate surgical resection. It is a reasonable and tolerable approach with manageable toxicity which gives substantial results in 2/3 of patients. This strategy also allows better selection of patients likely to benefit from surgical resection of their primary tumor and in some cases of their synchronous metastases. However, the efficacy of perioperative treatments should not decrease the quality of the surgical resection and especially mesorectal excision as well as the need for high quality pathological examination which must be very thorough with analysis of a sufficient number of lymph nodes. The efficacy of combined treatment in advanced rectal cancers is a major argument in favor of the multidisciplinary coordination required for optimal treatment of patients with rectal cancer.
