Efficacy of sesame oil versus placebo in the management of acute radiation-induced dermatitis in breast cancer patients: A double-blind randomized clinical trial.

Aim: Considering the anti-inflammatory and positive effects of sesame oil in treating skin diseases, the present research aimed to study its therapeutic effects on acute radiotherapy dermatitis in such patients.

Methods: Forty women with breast cancer during radiotherapy (for 5 weeks) were randomly grouped into two categories: sesame oil (20 patients) and placebo (20 patients). After each radiotherapy session, they were asked to use 3cc of the ointment on the treating field and continue the treatment until the end. They were examined weekly according to the staging criteria of the radiation therapy oncology group.

Results: No significant difference was observed in the first 3 weeks. In the fourth week, dermatitis grade 0 was 35%, grade 1 was 65%, and grade 2 was 0% in the intervention (case) group, while in the control group, they were 10%, 75%, and 15%, respectively. This difference was statistically significant (p = 0.046). Also, in the fifth week in the case group, dermatitis grade 0 was 25%, grade 1 was 70%, and grade 2 was 5%, while in the control group, they were 0%, 80%, and 20%, respectively. This difference was also statistically significant (p = 0.032).

Conclusion: Based on the findings, sesame oil, as a cheap and available herbal treatment, may be utilized in treating acute dermatitis caused by radiotherapy. However, an investigation with a larger sample size in several centers should be conducted to examine sesame oil effects in treating acute radio dermatitis more comprehensively.
