About this trial
This study is being done to evaluate cosmetic, patient-reported outcome measures (PROMs), and toxicities for women undergoing ultra-short whole breast irradiation (WBI) therapy with simultaneous integrated boost (SIB). 50 participants will be on study for up to 60 months.

Breast conserving surgery with negative margins and negative nodes (surgical axillary staging not mandatory), stage N0 or Nx
Treatment plan should include breast conserving surgery and adjuvant whole breast irradiation (WBI) therapy delivered with 3D-CRT or IMRT techniques
Disqualifiers
Mastectomy of ipsilateral breast
Lack of histologic diagnosis
Histologic involvement of the axillary or regional nodes or metastatic disease
Accelerated partial breast irradiation treatment plan

Trial outcomes
Primary outcomes
Harvard Breast Cosmesis Scale Score
4-point scale where 1 is excellent, 2 is good, 3 is fair, and 4 is poor.
Secondary outcomes
Change in BREAST-Q Score
The BREAST-Q questionnaire is scored from 0-100 where higher scores indicate better outcomes in each of 5 domains: Psychosocial Well-Being, Sexual Well-Being, Cancer Worry, Fatigue, and Impact on Work.
Incidence of Acute Toxicities
Acute toxicities (including breast dermatitis, induration) will be assessed after final treatment within 90 days of radiation therapy completion using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
Incidence of Late Toxicities
Late toxicities (including induration, fibrosis, shrinkage, and telangiectasia) will be assessed greater than 90 days of radiation therapy completion using CTCAE version 5.0
Ipsilateral Breast Tumor Recurrence-Free Survival
Kaplan-Meier curves will be used to estimate ipsilateral breast tumor recurrence-free survival.
