Purpose

In a small study at Johns Hopkins, women were treated with partial breast irradiation and chemotherapy given at the same time.

We are now testing in a bigger study whether giving partial breast irradiation and chemotherapy at the same time (our new method) has the same side effects and outcomes as giving partial breast irradiation and chemotherapy at different times(older method). In this study women who had their breast cancer removed but need radiation to the breast will be randomized to partial breast irradiation at the same time as chemotherapy or partial breast radiation at a different time than chemotherapy. Randomization is like flipping a coin but in this study about 2 of every 3 women will get the new method.

Margin negative surgery. For subjects with two breasts, they must have had a bilateral mammogram prior to surgery. Patient must have a Medical Oncology consult with the recommendation of chemotherapy. Recommended regimens are as follows: Cyclophosphamide and Doxorubicin (AC); Taxotere, Doxorubicin and Cyclophosphamide (TAC); Taxotere and Cyclophosphamide (TC); or Taxotere, Carboplatin withTrastuzamab (TCH) prior to registration; or Paclitaxel and Trastuzumab. The use of additional chemotherapy, hormonal therapy or Trastuzumab after the initial regimen is at the discretion of the Medical Oncologist. Other primary regimens are possible but the PI must be notified prior to enrollment. Partial breast irradiation must be scheduled to begin less than 71 days from the last breast surgical procedure. ECOG performance status ≤ 1. Women of child-bearing potential must have a negative (urine or blood) pregnancy test within 6 weeks prior to start of protocol therapy. Women of childbearing potential must also use effective non-hormonal contraception while undergoing radiation treatment and chemotherapy. Ability to understand and the willingness to sign a written informed consent document.
