Comparing Supplemental Topical Agents for the Treatment of Acute Radiation Dermatitis in Patients With Breast Cancer

PRIMARY OBJECTIVE: I. Determine the efficacy of Miaderm compared to Aquaphor in the treatment and/or prevention of radiation dermatitis caused by EBRT in breast cancer patients undergoing EBRT to the breast/chest wall. SECONDARY OBJECTIVE: I. Determine quality of life (QoL) and need for additional concomitant therapies to address dermatitis in breast cancer patients undergoing EBRT to the breast/chest wall using Miaderm compared to Aquaphor. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Beginning on day 1 of radiation therapy, patients apply Aquaphor twice daily (BID), but not within the four hours before EBRT, to the irradiated field until 2 weeks following completion of EBRT. ARM II: Beginning on day 1 of radiation therapy, patients apply Miaderm BID, but not within the four hours before EBRT, to the irradiated field until 2 weeks following completion of EBRT. After completion of study treatment, patients are followed up at 2 weeks and then at 90-120 days.
