In this observational study with nationwide population-based data from the Dutch Melanoma Treatment Registry, we analyzed real-world outcomes of first-line anti-PD-1 monotherapy in advanced melanoma patients diagnosed in 2015 to 2016. Overall survival (OS) was estimated with the Kaplan-Meier method. Competing risks analysis was used to estimate probabilities for second-line treatment, with death as competing risk. With a Cox model, the association of factors with OS was estimated. Patients who received anti-PD-1 monotherapy (n=550) had a median age of 65 years and 502 (95%) patients had an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-1, 383 (70%) had normal lactate dehydrogenase (LDH), 370 (67%) had stage IV-M1c disease, and in 441 (81%), brain metastases were absent. The median OS was 24 months [95% confidence interval (CI) 20-30 mo]. The median OS of patients normally eligible for phase III trial participation was 31 months (95% CI 23-not estimable). The BRAF mutation was associated with superior OS. ECOG PS of ≥1, symptomatic brain metastases, and liver metastases were associated with inferior OS and, together with elevated LDH, with death before second-line treatment. Patients with a complete response had a 2-year OS probability from first reported complete response of 92% (95% CI 86%-99%). Real-world advanced melanoma patients in the Netherlands have benefitted from anti-PD-1 monotherapy. ECOG PS ≥1, symptomatic brain metastasis, liver metastasis, and elevated LDH are important prognostic factors for su
