This prospective, non-randomized phase II study will evaluate the cosmetic outcome of using pencil beam scanning proton therapy for partial breast irradiation in patients diagnosed with early stage breast cancer. In addition the study will evaluate the acute and late toxicities, and the rates of ipsilateral breast tumor recurrence, both in situ and invasive disease.
To qualify for the trial, patients must be 50 years or older and have stage 0 (carcinoma in situ) or stage IA or IIA invasive carcinoma of the breast with no evidence of metastatic disease. The tumor size must be 3cm or less. Women must have undergone a partial mastectomy with margins free of invasive cancer and at least a 2mm margin for in situ disease. Patients must have clinically node negative disease. Patients with invasive disease must also have nodal assessment performed with either sentinel lymph node biopsy or axillary lymph node dissection and patients must have pathologically node negative disease. Accelerated partial breast irradiation (APBI) will utilize pencil beam scanning proton therapy. Partial breast irradiation will be delivered twice a day, at least 6 hours apart, over 5 treatment days.
This trial is designed to accrue 21 patients over a period of three years.
