Study Start Date: February 2004
Estimated Study Completion Date: December 2019
Estimated Primary Completion Date: December 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Proton Radiotherapy
Two week course of proton radiotherapy to the breast.
Radiation: Proton radiation therapy
Proton radiotherapy will start 2-4 weeks following surgical excision. The treatment area will include the lumpectomy site with an additional margin. Daily proton therapy will be given as an out-patient over a two week coarse.

Detailed Description:
Radiation therapy is considered standard treatment for most women with early stage breast cancer following lumpectomy. Post-lumpectomy radiotherapy is a proven treatment that reduces cancer recurrence in the breast and improves survival. When standard whole breast radiation techniques are utilized, portions of the chest wall, lung and heart may also receive significant doses of radiation which can lead to radiation induced complications. Radiation techniques that limit the treatment area to the portion of the breast where the cancer arose can minimize and even eliminate radiation dose to the chest wall, heart and lung. This is called partial breast radiotherapy. This study is designed to evaluate the use of proton beam radiotherapy to deliver partial breast radiotherapy in women with early stage breast cancer.
