| Summary |
DNA methylation profiles were recently proposed to have predictive value in various solid tumors. Therefore, we analyzed DNA methylation profiles of patients with stage IV metastatic melanoma, receiving first-line immune checkpoint inhibitors (ICIs) and correlated those with radiological response (iRECIST). Overall, 81 tissue samples from 71 patients with metastatic melanoma (27 (38.0%) female, 44 (62.0%) male) were investigated; median progression free survival was 8.5 months (0 – 104.1 months) and median overall survival was 30.6 months (0 – 104.1 months), respectively. 29 (40.8%) patients achieved an objective response. DNA methylation analyses revealed signatures correlating with radiological response to ICIs. Based on the 500 mostly differentially methylated genes, three clusters were identified with the majority of responders being in cluster 1 (12/12) and cluster 2 (12/24), and non-responders in cluster 3 (39/45). Our findings indicate that tumor DNA methylation profiling may be used as a predictor for ICI-response in patients with metastatic melanoma.
