Descriptive Information
Brief Title ICMJE	Radiation Therapy in Treating Women With Early-Stage Breast Cancer Who Have Undergone Breast Conservation Surgery
Official Title ICMJE	Randomised Trial Testing Intensity Modulated and Partial Organ Radiotherapy After Breast Conservation Surgery for Early Breast Cancer
Brief Summary	RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether intensity-modulated radiation therapy is more effective than standard radiation therapy in treating patients with early-stage breast cancer. PURPOSE: This randomized phase III trial is comparing radiation therapy regimens in treating women with early-stage breast cancer who have undergone breast-conservation surgery.
Detailed Description	OBJECTIVES: To test partial breast radiotherapy using intensity-modulated techniques following complete local tumor excision in women with low-risk, early stage breast cancer. OUTLINE: This is a multicenter study. Patients are stratified according to center (not participating in sub-studies vs participating in sub-studies). Patients are randomized to 1 of 3 treatment arms.; Arm I (control): Patients undergo standard whole breast radiotherapy once daily on days 1-5 (15 fractions) for 3 weeks.; Arm II: Patients undergo reduced whole breast radiotherapy (15 fractions) and standard partial breast radiotherapy (15 fractions) once daily on days 1-5 for 3 weeks.; Arm III: Patients undergo standard partial breast radiotherapy once daily on days 1-5 (15 fractions) for 3 weeks. All patients complete a family history questionnaire at baseline. Patients also undergo blood sample collection at baseline and paraffin-embedded tissue collection at follow-up for molecular studies analyzing inter-patient variation by microarrays. Patients in centers participating in sub-studies undergo quality of life and health economic assessment at baseline, 6 months, and 1, 2, and 5 years. These patients also undergo photographic assessment at baseline, 2 years, and 5 years. After completion of study treatment, patients are followed for 10 years.
