PRIMARY outcome

Timeframe: From the first day of radiotherapy up to eight weeks

Population: Patients with anal canal or rectum cancer with indication for RT and conventional treatment fractionation in Linear Accelerator (\< 250cGy/day); 18+ years old; no previous history of radiotherapy in the same treatment field/site (reirradiation); with no preexisting dermatitis at the irradiated site that would make it difficult to assess the skin; and no previous report of allergic reaction to any products used in the research.
