Study ID: NCT00321048

Conditions

Interventions

Active Breathing Coordinator

Study Description

Brief Summary: Cardiac perfusion changes have been seen after whole breast / chest wall irradiation for breast cancer. The Active Breathing Coordinator (ABC) device theoretically decreases radiation exposure to the heart during radiation for breast cancer. In this trial cardiac perfusion changes or lack thereof will be quantified in women treated with radiation for breast cancer while using the ABC device. The control group of the study will consist of patients randomized to radiation therapy without the ABC device.

Detailed Description: 50 left sided breast cancer patients will be randomized to receive breast/chest wall irradiation with or without ABC. Patients will receive radiation therapy at a dose of 180-200 cGy per fraction for 23-27 fractions to a total dose of 4600 - 4860 cGy. Additional radiation to the lumpectomy bed or mastectomy scar is at the discretion of the treating physician. The total dose to the tumor bed or mastectomy scar cannot exceed 6600cGy. Treatments will be given Monday through Friday. After the completion of radiation therapy, patients will be seen on the following schedule: A follow up examination will take place every 3-6 months for the first two years, then every 4-6 months for years for the next 3 years. After 5 years follow-up evaluations will occur annually. A SPECT scan will be obtained at 6 months post therapy. Patients must be 18 and older and must have histologically confirmed (by routine H\&E staining) invasive adenocarcinoma or Ductal Carcinoma In Situ of the left breast. Patients must have also undergone a segmental mastectomy (SM) or Mastectomy. Patients must not have received prior radiation therapy to the breast at any time for any reason. Patients must not be pregnant due to the potential for fetal harm as a result of this treatment regimen.
