Outcome Measures
Primary Outcomes (1)
Ipsilateral Breast Tumor Recurrence-free Survival
Lack of tumor recurrence in the treated breast as assessed by imaging and physical exam
Up to 5 years post-treatment completion, average of 48 months
Secondary Outcomes (1)
Overall Survival
Up to 5 years post- completion of treatment, average 48 months
Study Arms (1)
Proton Radiotherapy
EXPERIMENTALTwo week course of proton radiotherapy to the breast.
Interventions
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.
Eligibility Criteria
You may qualify if:
- Invasive ductal, medullary, papillary, colloid or tubular histologies
- Stages T1 or T2 (tumors \< or = 3 cm) from lumpectomy specimen.
- No more then 3 positive nodes on axillary dissection or negative sentinel node.
- Negative surgical margins (\>2mm)
You may not qualify if:
- Invasive lobular histology
- Previous chemotherapy for breast cancer
- Extensive intraductal component
- Collagen vascular disease
- Prior malignancy unless disease-free for 5 years
- Patients who are pregnant or lactating
