Phase II Study of Hypofractionated Intensity Modulated Radiation Therapy (IMRT) With Incorporated Boost in Early Stage Breast Cancer
Phase II Study of Hypofractionated Intensity Modulated Radiation Therapy (IMRT) With Incorporated Boost in Early Stage Breast Cancer
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Hypofractionated (fewer treatments than in standard radiation therapy) intensity-modulated radiation therapy (radiation directed at the tumor more precisely than in standard radiation therapy) with incorporated boost (an increase in the amount of radiation given during treatment) may kill more tumor cells.
PURPOSE: This phase II trial is studying how well adjuvant hypofractionated intensity-modulated radiation therapy with incorporated boost works in treating patients with early-stage breast cancer.
OBJECTIVES:
Primary
Secondary
OUTLINE: Patients undergo adjuvant hypofractionated intensity-modulated radiotherapy with incorporated boost once daily 5 days a week for 4 weeks.
Quality of life is assessed within 1 month of starting radiotherapy, at 6 weeks after completion of radiotherapy, and then every 6 months for 5 years.
Patients are followed at 6 weeks and then every six months for 5 years.
PROJECTED ACCRUAL: A total of 37-74 patients will be accrued for this study.
