Clinical Trial Summary

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.


Clinical Trial Description

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. ;
