Preoperative Accelerated Partial Breast Irradiation (APBI) for Women With Stage I and Select IIA Breast Cancer (GCC 0919)
The purpose of this study is to examine the feasibility to deliver PBI before the lumpectomy is performed. By administering the PBI before the lumpectomy, a smaller volume of breast tissue may be exposed to radiation. The PBI method used in this study is 3D (three dimensional) conformal external beam irradiation. 3D-conformal external beam irradiation uses an x-ray beam to deliver the radiation dose. Approximately 3 weeks after completion of the PBI, the cancer will be surgically removed.
This study will learn about the good and bad effects of 3D-conformal external beam irradiation PBI when given before the cancer has been removed by lumpectomy. The study will also learn about the feelings women have about how their breast looks after PBI and surgery.

- The primary endpoint of this study is determination of the reproducibility of delivering preoperative APBI in Stage I and Stage IIA breast cancers. [ Time Frame: 5 years ]This will be done by using 3D-CRT by evaluating the prescription isodose curves, dose inhomogeneity, and coverage of the volume as defined by CT treatment planning to delineate the target volume.
- Evaluation of pathologic response, cosmetic results, of lumpectomy wound healing and the overall complication rate, ipsilateral breast recurrence rate [ Time Frame: 5 years ]These endpoints will be accomplished by utilizing the pathology report; the cosmesis will be judged by the patient, radiation oncologist and/or surgeon, at stated follow-up intervals; and the breast recurrence rate will be evaluated by disease status at routine patient follow-up appointments, including yearly mammography.
