National audienceThe 21(st) SFRO Congress during October 2010 focused on three main topics: prostate, radiotherapy technical innovations (including reirradiation) and quality of life. The pitfalls of IMRT (treatment time, number of monitor unit, low doses) are in competition with arctherapy dynamic techniques that offer reduction treatment time for an equivalent ballistic. These techniques with high dose gradient should be coupled with the better imagery of repositioning (IGRT) to ensure benefice. A prospective evaluation of toxicity, clinical benefit on tumor control but also on quality of life of patients is necessary. In many current and future clinical trials, quality of life related to health will be a relevant outcome measurement to secure the importance of treatment for the patient and the health system.
