Correlation of tumor‐infiltrating immune cells of melanoma with overall survival by immunogenomic analysis

xloma.fota13 shared this article with you from Inoreader Correlation of tumor‐infiltrating immune cells of melanoma with overall survival by immunogenomic analysis Via Cancer Medicine Immunotherapy has shown excellent responses in melanoma, while the reaction is low. However, the molecular mechanisms of tumor infiltrated immune cells have not been explored. In this study, we found that higher ESTIMATE and immune scores were associated with a clinical‐stage in melanoma patients and also filtered the crosstalks between cells that immune cells. Our work revealed the immune cellular and molecular characteristics of melanoma, providing a method for selecting targets promoting immunotherapy efficacy. Abstract Aims Different types of tumor‐infiltrating immune cells not only augment but also dampen antitumor immunity in the microenvironment of melanoma. Therefore, it is critical to provide an overview of tumor‐infiltrating immune cells in melanoma and explore a novel strategy for immunotherapies. Methods We analyzed the immune states of different stages in melanoma patients by the immune, stromal, and estimation of stromal and immune cells in malignant tumor tissues using expression data (ESTIMATE) scores. Immune cell types were identified by the estimating relative subsets of RNA transcripts (CIBERSORTx) algorithm in 471 melanoma and 324 healthy tissues. Moreover, we performed a gene set variation analysis (GSVA) to determine the differentially regulated pathways in the tumor microenvironment. Results In melanoma cohorts, we found that ESTIMATE and immune scores were involved in survival or tumor clinical stage. Among the 22 immune cells, CD8+ T cells, M2 macrophages, and regulatory T cells (Tregs) showed significant differences using the CIBERSORTx algorithm. Furthermore, GSVA identified the immune cell‐related pathways; the primary immunodeficiency pathway, intestinal immune network for IgA, and TGF‐β pathways were identified as participants of the crosstalk in CD8+ T cells, Tregs, and M2 macrophages in the melanoma microenvironment. Conclusion These results reveal the cellular and molecular characteristics of immune cells in melanoma, providing a method for selecting targets of immunotherapies and promoting the efficacy of therapies for the treatment of melanoma.
