To evaluate factors associated with optimal cosmetic results at 36 months for early-stage breast cancer patients enrolled on the American Society of Breast Surgeons (ASBrS) MammoSite Breast Brachytherapy registry trial. ⋯ APBI delivered by MammoSite brachytherapy lead to good/excellent cosmesis in 93% of patients with 3-year follow-up. Breast wound infection, use of chemotherapy, and skin spacing were found to be the three most important predictors of cosmesis at 36 months in our cohort of patients.
