Following that, a ferroptosis-related gene signature was created. Time-dependent ROC curve and Kaplan–Meier analysis were calculated to determine its capability of prediction. Besides, several assessments were used to evaluate overall survival (OS), accompanied by the creation of a nomogram for the clinicopathologic factors and the ferroptosis-related gene signature we established. We also investigated the relationship between ferroptosis-related gene signature with three immune checkpoints and immune cell infiltration.Results: Our prognostic model included two genes (ALOX5, CHAC1). In both TCGA and GEO cohorts, OS was lower in high-risk category. Using our gene signature, we can reliably predict OS. Additionally, our gene signature can predict immune cell infiltration and SKCM immunotherapy response.Conclusion: Our gene signature has shown to be a reliable predictor of OS, reflect the immune microenvironment, and predict the effectiveness of immunotherapy for SKCM patients.Keywords: skin cutaneous melanoma, SKCM, ferroptosis, immune microenvironment, immune checkpointhttps://www.dovepress.com/construction-of-a-ferroptosis-related-gene-signature-for-predicting-su-peer-reviewed-fulltext-article-IJGMskin cutaneous melanomaskcmferroptosisimmune microenvironmentimmune checkpoint. |
