Impact of Radiation Therapy on Breast Conservation in DCIS

Dana-Farber Cancer Institute·observational·Posted Sep 25, 2014·Updated Sep 6, 2019

In Brief

An observational study for DCIS. Completed, enrolled 3,436 participants across 4 sites.

Detailed Summary

Large regional variation exists in the use of radiotherapy after breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS). Although patients who do not receive initial radiotherapy for DCIS are candidates for subsequent BCS if they experience a second breast event, many undergo mastectomy instead.
