During the study, the patients would undergo radiation of 5.2Gy for 5 fractions to the prophylactic radiation volumes and and a 6Gy per-fraction simultaneous boost to the tumor bed or other high-risk volumes. Acute toxicity of grade 2 or higher in the following 12 weeks after radiotherapy is the primary end point.
