Overview
Brief Summary
This phase II trial studies the side effects of intraoperative electron beam radiotherapy boost and to see how well it works in treating patients with stage I-II breast cancer undergoing surgery with reconstruction. Giving a single dose of electron beam radiation to the tumor cavity during the breast surgery before reconstruction may be a better way to kill tumor cells and shrink tumors.
Detailed Description
PRIMARY OBJECTIVES: I. To determine the rate of grade 3 breast fibrosis at 1 year in women undergoing lumpectomy with oncoplastic reconstruction and immediate intraoperative electron radiotherapy boost followed by adjuvant whole breast radiotherapy. SECONDARY OBJECTIVES: I. To determine the rate of 5 year ipsilateral breast tumor recurrence rate. II. To determine the change in self-reported cosmesis using the Breast Cancer Treatment Outcome Scale (BCTOS) questionnaire. III. To evaluate physician-reported cosmetic outcomes using the 4-point Harvard Cosmesis Scale and digital photographs. OUTLINE: Patients undergo standard of care lumpectomy and then undergo 1 fraction of intraoperative electron beam radiation therapy (IOERT) boost to the lumpectomy cavity. Patients then undergo standard of care oncoplastic reconstruction and whole breast radiation therapy. After completion of study treatment, patients are followed up at 1 month, 6 months, 1 year, and every year thereafter for 5 years.

Intervention: Lumpectomy
Treatment (IOERT boost)
Patients undergo standard of care lumpectomy and then undergo 1 fraction of IOERT boost to the lumpectomy cavity. Patients then undergo standard of care oncoplastic reconstruction and whole breast radiation therapy.
Intervention: Quality-of-Life Assessment
Treatment (IOERT boost)

Intervention: Questionnaire Administration
Treatment (IOERT boost)
Patients undergo standard of care lumpectomy and then undergo 1 fraction of IOERT boost to the lumpectomy cavity. Patients then undergo standard of care oncoplastic reconstruction and whole breast radiation therapy.
Intervention: Radiation Therapy
Treatment (IOERT boost)
Patients undergo standard of care lumpectomy and then undergo 1 fraction of IOERT boost to the lumpectomy cavity. Patients then undergo standard of care oncoplastic reconstruction and whole breast radiation therapy.
Intervention: Reconstructive Surgery
Outcomes
Primary Outcomes
Incidence of adverse events in the first 30 patients enrolled as graded by the National Cancer Institute Common Toxicity Criteria version 4.0
Time Frame: Up to 30 days after surgery and IOERT boost
If 4 or more complications in the first 10 patients, 7 or more out of the first 20 patients or 9 or more out of 30 patients are observed, then the study will be deemed not safe to continue. Summary statistics will be used to report all complications.
Rate of grade 3 fibrosis using the Late Effects Normal Tissue Task Force-Subjective, Objective, Management, Analytic scales
Time Frame: At 1 year from the end of therapy
The proportion of patients with an overall response rate of grade 3 fibrosis at 1 year from the end of therapy along with the exact binomial confidence interval for the rate will be calculated.
Secondary Outcomes
- Quality of life assessed by Breast Cancer Treatment Outcome Scale(Up to 3 years after completion of radiation therapy)
- Change in self-reported cosmesis using the BCTOS(Baseline up to 3 years)
- Physician reported cosmesis using the Harvard Breast Cosmesis scale and digital photographs(Up to 3 years after completion of radiation therapy)
- Rate of ipsilateral breast tumor recurrence(At 5 years)
