Genetic Susceptibility to Radiation-Induced Skin Reactions in Racial/Ethnic Groups of Patients With Breast Cancer
Basic Trial Information
RATIONALE: Radiation therapy uses high-energy x rays to kill tumor cells. Radiation therapy may cause skin reactions when patients are exposed to high-energy x rays. Studying the genetic pattern of patients before and after radiation therapy may help doctors prevent toxicity and plan the best treatment.
PURPOSE: This clinical trial studies genetic susceptibility to radiation-induced skin reactions in racial/ethnic groups of patients with breast cancer.
Further Study Information
OUTLINE: This is a multicenter study. Patients are stratified according to race/ethnicity (Whites* vs Black/African Americans vs Hispanic/Latinos vs Asians/Native Hawaiians/Pacific Islanders vs American Indians/Alaskan Natives). NOTE: *This stratum is closed as of April 25, 2012.
Patients undergo adjuvant radiotherapy after breast-conserving surgery.
Blood and urine samples are collected at baseline and last day of radiotherapy for genotyping, DNA damage, cell cycle assays, urine cotinine, inflammatory immune response biomarkers, and tumor-killing activity by BeadArray System, Comet assay, flow cytometry-based assay, Cell-Cycle G2 Delay Assay, Oxygen Radical Absorbance Capacity (ORAC) assay, and ELISA.
Patients are assessed for acute toxicity by research staff using the ONS Criteria for Radiation-Induced Acute Skin Toxicity at baseline, week 3, and at 1 and 2 months after radiotherapy. Patients are also assessed for chronic toxicity by research staff using the Chronic skin toxicity questionnaire (RTOG SOMA Criteria for RT- Induced Breast/Chest Wall Late Skin Toxicity) at 6 and 12 months after completion of radiotherapy. Photographs of the breast, chest wall, and contralateral breast are also taken at baseline, week 3, last day of radiotherapy, and at 1, 2, 6, and 12 months after completion of radiotherapy.
Patients complete the Breast Cancer Risk Study Questionnaire, the Functional Assessment of Cancer Therapy Breast (FACT-B), the Modified Skindex, and the B39 Quality-of-Life (QOL) Questionnaire at baseline, last day of radiotherapy, and at 1, 2, 6, and 12 months after radiotherapy.
