Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
1. To test the hypothesis that when prone, patients treated with 3D-CRT breast radiotherapy and randomly assigned to either a weekly or a daily boost to the tumor bed develop acute toxicity that is not significantly worse than that of a concurrent cohort of patients treated with IMRT randomly assigned to a weekly or daily boost regimen. 2. To test the hypothesis that when prone, patients treated with 3D-CRT breast radiotherapy, randomly assigned to either a weekly or a daily boost to the tumor bed develop late toxicity that is not significantly worse than that of concurrent cohort of patients treated with IMRT randomly assigned to a weekly of daily boost. 3. To test hypothesis that 5 year local control rates of ≤ 5% in-breast recurrence can be achieved in each of the two randomized arms, for either technique tested.
