Abstract:

〔Abstract〕 Objective: To systematically evaluate the incidence of cutaneous adverse reactions induced by dabrafenib combined with trametinib in the treatment of melanoma. Methods: PubMed, EMbase, Cochrane Library, Web of Science, CNKI, VIP, Wanfang and China Biomedical Literature Database were searched by computer, and relevant published studies at home and abroad were collected. The retrieval period was from the establishment of the database to December 2020. Stata 15.1 software was used to calculate the incidence of cutaneous adverse reactions. RevMan 5.3 software was used to assess the relative risk(RR) for all grades of cutaneous adverse reactions. Results: A total of 10 studies involving 2 623 patients were included. The incidence of cutaneous adverse reactions of all grades in the treatment of melanoma with dabrafenib combined with trametinib were as follows:exanthem 22%[95%CI(0.19, 0.26)], pruritus 10%[95%CI(0.08, 0.11)], hyperkeratosis 7%[95%CI(0.04, 0.10)], alopecia 5%[95%CI(0.04, 0.07)], cutaneous papilloma 1%[95%CI(0.01, 0.03)], acneiform dermatitis 10%[95%CI(0.06, 0.14)], cutaneous squamous cell carcinoma 2%[95%CI(0.00, 0.04)], dry skin 10% [95%CI (0.08, 0.12)] and erythema 11%[95%CI(0.09, 0.13)]. Compared with BRAF inhibitor alone, dabrafenib combined with trametinib reduced the incidence of pruritus, hyperkeratosis, alopecia, cutaneous papilloma, and cutaneous squamous cell carcinoma(P<0.05). Conclusion: Exanthem is a common cutaneous adverse reaction in patients with melanoma treated with darafenib combined with trametinib. Compared with BRAF inhibitor alone, the combination drug significantly reduced the occurrence of cutaneous adverse reactions.
