- Brief Summary
This clinical trial compares two supplemental topical agents (Aquaphor and Miaderm) for the treatment of acute radiation dermatitis in patients with breast cancer undergoing radiation therapy. Radiation dermatitis is a radiation-induced skin reaction which can cause itching, swelling, pain, and general discomfort. Aquaphor is a commonly available, inexpensive, petrolatum-based multi-purpose ointment designed to protect and sooth extremely dry skin, chapped lips, cracked hands and feet, minor cuts and burns, and many other skin irritations. Miaderm is a water-based cream and contains ingredients like calendula, hyaluronate, and aloe vera which may help reduce occurrence and severity of radiation dermatitis. Both are commonly recommended and used by breast cancer patients undergoing external beam radiation therapy (EBRT). However, it is not known whether one is better than the other in treating or preventing radiation dermatitis.
- Detailed Description
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.

Group Intervention Description Arm I (Aquaphor) Petrolatum-Mineral Oil-Lanolin-Ceresin Ointment Beginning on day 1 of radiation therapy, patients apply Aquaphor BID, but not within the four hours before EBRT, to the irradiated field until 2 weeks following completion of EBRT. Arm I (Aquaphor) Quality-of-Life Assessment Beginning on day 1 of radiation therapy, patients apply Aquaphor BID, but not within the four hours before EBRT, to the irradiated field until 2 weeks following completion of EBRT. Arm I (Aquaphor) Questionnaire Administration Beginning on day 1 of radiation therapy, patients apply Aquaphor BID, but not within the four hours before EBRT, to the irradiated field until 2 weeks following completion of EBRT. Arm II (Miaderm) Agent Affecting Integumentary System 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. Arm II (Miaderm) Quality-of-Life Assessment 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. Arm II (Miaderm) Questionnaire Administration 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.
- Primary Outcome Measures
Name Time Method Acute Radiation Dermatitis Up to 120 days after completion of radiation therapy Depending on prescribed duration of radiation treatment, each subject will contribute between 5 and 8 periodic assessments for the presence of acute radiation dermatitis Radiation Therapy Oncology Group / European Organization for Research and Treatment of Cancer (RTOG/EORTC toxicity score of 2 or higher). The hypothesized association between randomized treatment and the repeated binary outcome of Acute Radiation Dermatitis will be tested using repeated measures logistic regression. That model will be implemented with PROC GENMOD (SAS software) for a generalized linear regression model with generalized estimating equation (GEE) for binary data with logit link function. In this way, the analysis will recognize the within-patient correlation inherent in repeated assessments.
- Secondary Outcome Measures
Name Time Method Quality of life (QoL) Up to 120 days after completion of radiation therapy Skindex-16 is a single-page, validated measure of the effects of skin disease on patients' quality of life. The 16 questions address Symptoms (4 items), Emotions (7 items), and Functioning (5 items). Using a 7-level scale that is scored from 0 (Never bothered) to 100 (Always bothered), each question asks how much during the last 7 days the patient has been bothered by a specific aspect of their disease. Responses are averaged to generate a Global score and 3 domain-specific sub-scores, all ranging from 0 to 100, with higher scores indicating worse disease-related quality of life. Evaluated by the Skindex-16 questionnaire will be compared between the two study arms. T tests will be applied to assess mean differences between arms at each time point.
Supportive measures Up to 120 days after completion of radiation therapy Depending on prescribed duration of radiation treatment, each subject will contribute between 5 and 8 periodic assessments for the use of Concomitant Therapy for acute radiation dermatitis. The hypothesized association between randomized treatment and the repeated binary outcome of Concomitant Therapy will be tested using repeated measures logistic regression. Similar to the analysis of the Primary Endpoint described above, this model will be implemented with PROC GENMOD (SAS software) for a generalized linear regression model with GEE for binary data with logit link function and will consider potential covariates and possible treatment-by-time interaction as described above for the Primary Endpoint analysis.
