The efficacy of medicinal plant preparations in the alleviation of radiodermatitis in patients with breast cancer: A systematic review of clinical trials

Abstract

AbstractRadiodermatitis in breast cancer patients varies from mild irritation to life‐threatening lesions. Several studies suggest a role for topical corticosteroid ointments in the treatment of radiodermatitis. Yet, to avoid the adverse effects of corticosteroids, many authors recommend the use of topical herbal products instead. The therapeutic role of herbal treatments has yet to be fully understood. This systematic review evaluates the role of topical or oral herbal medicines in radiodermatitis prevention and treatment. A systematic search of four databases (Embase, PubMed, Web of Science, and Scopus) was performed without language and time restrictions from their inception until April 2023. The bibliographies of potential articles were also searched manually. Studies evaluated and compared the effects of herbal preparations with the control group, on dermatitis induced by radiotherapy for breast cancer. The Cochrane risk of bias tool was used to assess the included studies. Thirty‐five studies were included in the systematic review. Studies which used herbal drugs including topical and oral formulations were evaluated. Herbal monotherapy and combination therapy were reported, and their effects on radiodermatitis were explained in the systematic review. In conclusion, henna ointments, silymarin gel, and Juango cream were reported to reduce the severity of radiodermatitis. These agents should be considered for radiodermatitis prophylaxis and treatment. The data on aloe gel and calendula ointment were conflicting. Further randomized controlled trials of herbal medications and new herbal formulations are required to determine their effects on breast cancer radiodermatitis.
