Summary
Brief summary (as posted)
This phase II trial studies how well giving accelerated radiation therapy (RT) after surgery works in treating patients with breast cancer. RT uses high energy x rays to kill tumor cells. Giving RT after surgery may kill any remaining tumor cells

- Radiation Therapy
- description
- Patients undergo hypofractionated accelerated radiation therapy over 11 weekdays (for 15 elapsed days) within 21-63 days after last surgery or last course of chemotherapy. Treatment continues in the absence of disease progression or unacceptable toxicity.

Inclusion Criteria: * Invasive ductal, medullary, papillary, colloid (mucinous), or tubular histologies; invasive lobular carcinomas are allowed * American Joint Committee for Cancer (AJCC) Stage IIa - IIIc (pathologic stage T0N1-3, T1N1-3, T2N1-3, T3N0-3, T4N0-3, all M0 status) histologically confirmed invasive carcinoma of the breast treated with mastectomy and either sentinel node biopsy or axillary dissection; inflammatory carcinoma (T4d) is allowed * Patients with locally advanced breast cancer on clinical exam and diagnostics ( \> 3 cm and/or clinically node-positive) who have mastectomy after induction chemotherapy are allowed * Multifocal/multicentric disease is allowed * Negative inked histologic margins of mastectomy (no invasive cells at margin) or positive margin at pectoralis fascia or skin * Tamoxifen, Arimidex or other hormonal therapy is allowed; it may begin any time relative to the radiation at the discretion of the treating physician * Chemotherapy is allowed, if chemotherapy is indicated the chemotherapy can be delivered first, followed by radiation therapy beginning 21-63 days after the last cycle of chemotherapy or the radiation therapy can be delivered first and the chemotherapy can be delivered no earlier than 21 days post radiation therapy; neoadjuvant chemotherapy is allowed; radiation therapy will be delivered after mastectomy or after any adjuvant chemotherapy as described above * Chest wall reconstruction is allowed * The patient must be enrolled and have treatment planning between 14-63 days from date of last surgery or last cycle of chemotherapy, and radiation must start within 21-63 days of date of last surgery or last cycle of chemotherapy * Signed study-specific informed consent form prior to study entry * Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 Exclusion Criteria: * Patient with distant metastases (M1) * Patients with ductal or lobular carcinoma in-situ alone (no invasive component) and patients with non-epithelial breast malignancies such as sarcoma or lymphoma * Patient with T1N0 or T2N0 disease * Prior radiation therapy to the chest * Patients with collagen vascular diseases, specifically systemic lupus erythematosus, scleroderma, or dermatomyositis * Patients with co-existing medical conditions with life expectancy \< 2 years * Patients with psychiatric (with the possible exception of incompetence as defined by New Jersey \[NJ\] law) or addictive disorders that would preclude obtaining informed consent * Other malignancy, except non-melanomatous skin cancer, \< 5 years prior to participation in this study; the disease-free interval from any prior carcinoma must be continuous * Women who are pregnant or lactating due to potential exposure of the fetus to RT and unknown effects of RT to lactating females * Women who are able to conceive and unwilling to practice an effective method of birth control; women of childbearing potential must have a negative urine or serum pregnancy test within 7 days prior to treatment
