CACNA1C mutation as a prognosis predictor of immune checkpoint inhibitor in skin cutaneous melanoma
Abstract
Aims: There is an urgent need for appropriate biomarkers that can precisely and reliably predict immunotherapy efficacy, as immunotherapy responses can differ in skin cutaneous melanoma (SKCM) patients. Methods: In this study, univariate regression models and survival analysis were used to examine the link between calcium voltage-gated channel subunit alpha 1C (CACNA1C) mutation status and immunotherapy outcome in SKCM patients receiving immunotherapy. Mutational landscape, immunogenicity, tumor microenvironment and pathway-enrichment analyses were also performed. Results: The CACNA1C mutation group had a better prognosis, higher immunogenicity, lower endothelial cell infiltration, significant enrichment of antitumor immune response pathways and significant downregulation of protumor pathways. Conclusion:CACNA1C mutation status is anticipated to be a biomarker for predicting melanoma immunotherapy effectiveness.
Plain language summary
Aims: The treatment to make the immune system work better is also used to treat a skin cancer called skin cutaneous melanoma (SKCM). We need new ways to predict if the treatment will work. Methods: We looked at two groups of people getting the treatment to make the immune system work better. One group had a special change in their bodies, and the other group did not. We looked at how this change affected the patients. We also looked at how to make their immune system stronger. Results: We found that people with mutations tend to have better chances of getting better from their sickness. Conclusion: We think that this might be a good way to tell if immunotherapy will work well for this type of SKCM.
