Popis: Abstract Background Anti‐PD‐1‐based immunotherapy is considered a preferred first‐line treatment for advanced BRAF V600‐mutant melanoma. However, a recent international multi‐center study suggested that the efficacy of immunotherapy is poorer in Asian patients in the non‐acral cutaneous subtype. We hypothesized that the optimal first‐line treatment for Asian patients may be different. Methods We retrospectively collected data of Asian patients with advanced BRAF V600‐mutant melanoma treated with first‐line BRAF/MEK inhibitors (BRAF/MEKi), anti‐PD‐1 monotherapy (Anti‐PD‐1), and nivolumab plus ipilimumab (PD‐1/CTLA‐4) between 2016 and 2021 from 28 institutions in Japan. Results We identified 336 patients treated with BRAF/MEKi (n = 236), Anti‐PD‐1 (n = 64) and PD‐1/CTLA‐4 (n = 36). The median follow‐up duration was 19.9 months for all patients and 28.6 months for the 184 pa tients who were alive at their last follow‐up. For patients treated with BRAF/MEKi, anti‐PD‐1, PD‐1/CTLA‐4, the median ages at baseline were 62, 62, and 53 years (p = 0.03); objective response rates were 69%, 27%, and 28% (p
