Partial-Breast Radiation Therapy in Treating Women With Early-Stage Breast Cancer
A Single Institution, Prospective, Non-randomized Study of Partial Breast Irradiation Using the MammoSite Radiation Therapy System (Breast Brachytherapy Applicator)
RATIONALE: Internal radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. It may also cause less damage to normal tissue.
PURPOSE: This phase II trial is studying how well partial-breast radiation therapy works in treating women with early-stage breast cancer.

OBJECTIVES:
Primary
- To examine the efficacy of MammoSite® Radiation Therapy System (RTS) in delivering partial-breast irradiation to women with early-stage breast cancer.
Secondary
- To assess the toxicities associated with MammoSite® RTS in these patients.
- To evaluate the cosmetic results in the breast after brachytherapy with the MammoSite® RTS.
- To correlate the cosmetic results with the use of chemotherapy, volume of the implant, and distance from the implant to the skin.
- To correlate the local recurrence rate with time between surgery and implant.
OUTLINE: Patients undergo placement of the MammoSite® Radiation Therapy System (RTS) device into the cavity where the tumor was removed either at the time of surgery or percutaneously under ultrasound guidance after surgery. Within 2-5 days after the device implant, patients undergo partial-breast irradiation delivered by MammoSite® RTS twice daily for 5 days.
After completion of study therapy, patients are followed up periodically for 5 years.

- Re-excision to obtain negative margins allowed
- Must have adequate skin spacing between balloon surface and surface of the skin and lung (≥ 7 mm)
- No multicentric carcinoma (invasive or DCIS) in more than one quadrant
- No clinically or pathologically positive regional lymph nodes
- No extensive intraductal component, defined as DCIS extending beyond the primary invasive component into normal breast parenchyma and composing > 25% of the primary tumor
