Radiation Therapy in Treating Women With Invasive Breast Cancer

August 19, 2013 updated by: University of California, San Francisco

The Relationship Between Plasma Transforming Growth Factor-beta 1 (TGF-β) and Fractionation in Radiotherapy for Breast Cancer: A Randomized Study

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 3.5 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.
