|Condition or disease||Intervention/treatment||Phase|
|Breast Neoplasms Carcinoma, Ductal Adenocarcinoma||Device: Active Breathing Coordinator||Not Applicable|
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.

Experimental: ABC (Active Breathing coordinator)
Patients are randomized to ABC arm will receive radiation with ABC. Cardiac perfusion will be assessed at baseline and 6 months after treatment and the difference will be compared to that seen in the No ABC arm.
Device: Active Breathing Coordinator
A SPECT scan will be used to determine if the active breathing device reduces radiation toxicities.
No Intervention: No Active Breathing Coordinator
Patients randomized to the No ABC arm will receive radiation without ABC.Cardiac perfusion will be assessed at baseline and 6 months after treatment and the difference will be compared to that seen in the ABC arm.
- Efficacy of Active Breathing Coordinator (ABC) Device as Determined by the Mean Apical Perfusion Score [ Time Frame: 6 months post-radiation ]Efficacy of the ABC device in protecting the heart from radiation (XRT) damage in patients with L breast cancer is determined by the change in cardiac perfusion (mean apical perfusion score) as measured by SPECT between baseline and 6 month follow up. A score of 1 represents an equivocal or mild reduction in perfusion, 2 represents moderately reduced perfusion, 3 represents severely reduced perfusion, and 4 indicates absent perfusion.
