AIM: The purpose of this study is to compare topical betamethasone-17-valerate and olive oil cream in preventing radiation-induced dermatitis (RID) in breast cancer patients and to provide prospective data evaluating the quality of life, subjective symptoms, and treatment satisfaction reported by the patients.
METHODS: This was a prospective, double-blind, randomized, parallel, placebo-controlled trial. A total of 132 patients were randomized into three groups to receive either olive oil cream (G1), betamethasone-17-valerate (Betnovate® cream, GlaxoSmithKline) (G2), or unmedicated cream base (G3) throughout radiotherapy (RT) and 2 weeks after. The study is registered on clinicaltrials.gov with ID: NCT05285943, Date: November 2021.
RESULTS: A total of 128 patients were included in the final analysis. Betamethasone and olive oil significantly differed from the unmedicated cream base at weeks 1 to 4 (P < 0.05). At week 5, only significance was observed between olive oil and unmedicated cream base (P = 0.013), and the mean RTOG (Radiation Therapy Oncology Group) score was significantly lower in olive oil and betamethasone groups than in the unmedicated cream base group (P < 0.05 at weeks 1-5) but, there was no significant difference between olive oil and betamethasone (P > 0.999). Furthermore, the percentage of patients who developed grade 3 at the end of the follow-up was significantly different between the olive oil group and the unmedicated cream base group (27.9% vs. 61%, P = 0.004). Additionally, olive oil and betamethasone had non-significant delayed grade 2 and grade 3 development (P > 0.999).
CONCLUSION: Olive oil cream is as effective as betamethasone in alleviating RID in patients treated with adjuvant radiotherapy for breast cancer.
