Aim: This study is aimed to evaluate the effects of boron on radiation-induced skin reactions (RISR) in breast cancer patients. Material and methods: After 47 patients with invasive ductal carcinoma underwent radiotherapy, 23 (49%) received a boron-based gel, and 24 (51%) received placebo. Assessments were performed according to the Radiation Therapy Oncology Group (RTOG) skin scale and a Five-Point Horizontal Scale (FPHS). Results: At the end of the fifth week of radiotherapy, the RTOG scores in the boron group were significantly lower than those in the placebo group (p = .024). The FPHS score was higher in the placebo group than in the boron group, and this difference was not statistically significant (p = .079). Conclusion: Using the RTOG scoring system, we revealed that the application of a boron-based gel diminished RISR. The mechanism of action is unclear but may be related to antioxidant, wound healing, and thermal degradation effects of boron.
