CD8A and neoplasm: In Endometrial cancer, CTSW is found to be one of the genes correlated positively with tumor infiltration levels of B cells, CD8+ T cells, CD4+ T cells, macrophages, and dendritic cells, indicating that composition of tumor microenvironment affects clinical outcomes of Endometrial cancer patients, and suggesting that it may provide a basis for development of novel prognostic biomarkers and immunotherapies for patients with Endometrial cancer [64].
