71 Relations between radiation dermatitis degrees during radiation therapy and dose levels, for different regions in breasts and chest walls

Abstract

Introduction. Despite the use of planning maximal dose threshold constraint in radiation therapy (RT) treatments, radiation dermatitis in breast cancer continue to be among the most common side effects during treatment. In order to minimize dermatitis, we have divided previous general maximum dose constraint threshold (107 % of prescribed dose) to different specifics thresholds associated to different specifics regions in breasts and chest walls.
