Radiation Management of DCIS and Elimination of RT in Low-risk Disease

Purpose of Review This study summarizes the management and outcomes of ductal carcinoma in situ (DCIS). It will review recent literature including data supporting the use of a radiation boost, partial breast irradiation, endocrine therapy, HER2 therapy, genomic assays, and omission of radiation or surgery. Recent Findings Evidence suggests there are a cohort of patients who may benefit from either tumor bed boost, partial breast irradiation, or omission of radiation. Summary The management for DCIS is continuously evolving in order to identify patients who have higher risk features that necessitate aggressive treatment and those with more favorable features in whom we can de-escalate treatment.
