Abstract: Protracted preoperative radiochemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neoadjuvant treatments for resectable stage II–III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a “Total Mesorectal Excision”. Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: “rectal cancer”, “preoperative radiotherapy”, “phase II–III”, “preoperative chemotherapy”, “adjuvant chemotherapy” and “surgery”. Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neoadjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.
