Brief Summary
The goal of the study is to investigate the feasibility of enabling a second chance for breast conservation in patients with in-breast recurrences after a previous lumpectomy and RT, investigators propose to test partial breast irradiation with the target volume encompassing the entire surgical bed with 1.0-1.5 cm margins. An additional goal of the study is to investigate the feasibility of enabling a second chance for breast conservation in patients with inbreast recurrences after a previous lumpectomy and PBI, the investigators propose to test whole breast RT (WBRT) with the target as the whole breast volume.

Outcome Measures
Primary Outcomes (1)
Rate of treatment related adverse events as graded by CTCAE version 5.0
The primary endpoint of the study is to test the feasibility in terms of acute toxicity of a protocol of partial breast re-irradiation for breast cancer treatment in a previously irradiated whole breast, as defined by the rate of grade ≥ 3 treatment-related skin, fibrosis, and breast pain AEs, as graded by CTCAE version 5.0.
up to 1 year from completion of radiation treatment
Secondary Outcomes (12)
Number of participants with late toxicity will be measured as graded by CTCAE version 5.0
up to 60 months
Change in number of participants with skin changes
baseline, approx. week 1- week 2 of radiation, 6 months, 12 months, 24 months, 36 months, 48 months, 60 months.
Change in Quality of life as assessed by Breast Cancer treatment outcome scale (BCTOS)
baseline, approx. week 1- week 2 of radiation, 6 months, 12 months, 24 months, 36 months, 48 months, 60 months.
Number of participants who demonstrate local control
60 months
Disease free survival (DFS) will be measured
60 months
- +7 more secondary outcomes
Study Arms (2)
Radiation Therapy - PBI
OTHERPatients will be treated with the fractionation of 30 Gy in 5 fractions over 1-2 weeks, which is the accelerated partial breast irradiation (PBI) fractionation scheme of choice for RT naïve patients at New York Presbyterian using External Beam Radiation Therapy (EBRT)
Radiation Therapy - WBRT
OTHERPatients will be treated with the fractionation of 4050 cGy in 15 fractions over 3 weeks, which is the standard whole breast RT (WBRT) fractionation scheme of choice for RT naïve patients at New York Presbyterian using External Beam Radiation Therapy (EBRT)
