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