Brief Summary: RATIONALE Radiation therapy uses high-energy x-rays to kill tumor cells Giving radiation therapy in different ways may kill more tumor cells

PURPOSE This randomized clinical trial is studying the side effects and best way to give radiation therapy and to see how well it works in treating patients with invasive breast cancer
Detailed Description: OBJECTIVES

Primary

Compare the ratio between post- and pre-treatment plasma transforming growth factor-beta 1 TGF-β in women with invasive breast cancer undergoing hypofractionated radiotherapy vs standard-fractionated external-beam radiotherapy

Secondary

Establish longitudinal serum and plasma biorepository for retrospective evaluation of TGF-β and other biomarkers with special relevance to radiation response
Correlate pre-treatment plasma TGF-β levels with clinical fibrosis development

OUTLINE This is a randomized study Patients are randomized to 1 of 2 treatment arms

Arm I hypofractionated radiotherapy Patients undergo external-beam radiotherapy once daily 5 days a week for up to 35 weeks 16 fractions total
Arm II standard fractionated radiotherapy Patients undergo radiotherapy as in arm I at a lower dose for up to 5 weeks 25 fractions total

After completion of study treatment patients are followed every 6 months for 2 years and then annually for 3 years

PROJECTED ACCRUAL A total of 100 patients will be accrued for this study
