Study Summary
This study will evaluate the local control, complication rates, cosmetic results, and quality of life between patients treated with a single fraction vs. five fractions of accelerated partial breast irradiation (S\_APBI vs. F\_APBI) when used as the sole method of radiation therapy.
Primary Outcome
-IBTRs will be categorized as local (infield) if they occur within the prescription isodose volume, peripheral if between the prescription isodose volume and a volume 2 cm outside of the prescription isodose volume, and non-contiguous or extrafield if they are beyond the peripheral volume described above.
