High Dose Rate Intracavitary Brachytherapy as the Sole Method of Radiation Therapy for Breast Carcinoma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00165581

Brief Summary:
The purpose of this study is to understand the side effects (skin reaction, infection and abscess formation) at the site of radiation treatment, which my occur during the treatment and following 2 months using a new method of radiation therapy for breast cancer.

Condition or disease Intervention/treatment Phase
Breast Cancer Device: High Dose Intracavitary Brachytherapy Not Applicable

Detailed Description:
  • Radiation treatment will be delivered in an outpatient setting, twice a day in 5 consecutive treatment days. There will be a minimum 6-hour interval between the two daily treatments. The applicator is a simple tube with an inflatable balloon at one end, a channel in the middle of the tube for treatment, and two adapters at the other end.
  • Following surgical removal of the breast cancer, the radiation oncologist with the assistance of the surgeon or radiologist will place the applicator in the surgical cavity. A small radioactive source, iridium-192, will be inserted into the applicator by a special machine and after the final treatment, the applicator will be removed.
  • The following procedures will be done while the patient is on radiation therapy: post-partial mastectomy mammogram of micro-calcifications to confirm complete removal; CT scans for radiation treatment planning; monitoring of the skin for side effects; photographs of the breasts prior to the surgery, prior to placement of the applicator and at 60 days after radiation treatment to evaluate the cosmetic outcome of the treatment.
  • Participation in this study will last approximately 2 months after completion of radiation treatment.
