Abstract

Rectal cancer is a common pathology in the elderly. The standard for advanced rectal tumors is a chemoradiotherapy regimen combined 50Gy with concomitant chemotherapy followed by a surgery. This treatment induces interruptions of chemoradiotherapy and toxicities G3–4 more important in people over 70 years of age. Hypofractionated radiotherapy 5×5Gy with surgery following week is an alternative. All retrospective studies on this fractionation report an excellent immediate and chronic tolerance. The randomized phase III NACRE trial, comparing these 2 radiotherapy, followed by surgery at 6–8 week, established a standard in the management of the elderly patients.
