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.

  • Hemoglobin >= 8 g/dL

  • Women of childbearing potential must have a negative urine or serum pregnancy test within 14 days of study entry

  • Women of childbearing potential must be non-pregnant and non-lactating and willing to use medically acceptable form of contraception during radiation therapy

Exclusion Criteria
  • Clinical T4, N2 or N3, M1 pathologic stages III or IV breast cancer

  • Non-epithelial breast malignancies such as sarcoma/lymphoma
  • Male breast cancer
  • Paget's disease of the nipple

Primary Outcome Measures
NameTimeMethod
Incidence of adverse events in the first 30 patients enrolled as graded by the National Cancer Institute Common Toxicity Criteria version 4.0Up 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 scalesAt 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 Outcome Measures
NameTimeMethod
Quality of life assessed by Breast Cancer Treatment Outcome ScaleUp to 3 years after completion of radiation therapy

determine the rate of surgical complications necessitating hospital readmission or return to the operating room within 30 days of surgery + IOERT

Change in self-reported cosmesis using the BCTOSBaseline up to 3 years

The mean and standard deviation of the self-reported cosmesis using the BCTOS cosmesis scale will be summarized over time. The change over time using a repeated measures model or non-parametric methods, if appropriate, will be examined.

Physician reported cosmesis using the Harvard Breast Cosmesis scale and digital photographsUp to 3 years after completion of radiation therapy

physician-reported cosmetic outcomes using the 4-point Harvard Cosmesis Scale and digital photographs

Rate of ipsilateral breast tumor recurrenceAt 5 years

The exact binomial confidence interval for the rate will be calculated.
