NSABP B-51/RTOG 1304 (early-stage breast cancer who have undergone surgery)

What is the Purpose of this Study?

If you choose to join this study, you will:
- Have a mammogram or MRI of both your breasts
- Have blood tests to check your blood counts
- Have a blood pregnancy test if you are a woman who can get pregnant
- Be randomized (put into one of two groups by chance like a flip of a coin) after your surgery to one of two groups
-- Group 1: Patients who have had a lumpectomy will receive radiation therapy to the breast.
Patients who have had a mastectomy will not receive radiation therapy
-- Group 2: If you had a lumpectomy, you will receive radiation therapy to your breast and lymph nodes.
If you had a mastectomy, you will have radiation to the area where your breast used to be and to the lymph nodes.
- Continue having mammograms every year until 10 years after you joined the research study

- Be in the study for up to 10 years
- Have a physical exam every 6 months for the first couple of years
What is the Condition Being Studied?
Breast cancer with cancer cells in the lymph nodes at the time of diagnosis which clear after chemotherapy and surgery

Who Can Participate in this Study?

Adult women ages 18 and older who:

- Have finished chemotherapy

- Have had a mastectomy or lumpectomy with all cancer lymph nodes removed

- Have no prior history of cancer or chest radiation therapy

- Are not pregnant or nursing

Age Group
Participating Institutions

What is Involved?

We are doing this study to see if participants with cancer cells in the lymph nodes (at the same time that the breast cancer is diagnosed) and have chemotherapy before surgery that clears the cancer cells from the lymph nodes.
