Initial analysis of The Cancer Genome Atlas (TCGA) ovarian cancer cohort (n = 374; R0: 75 cases; non-R0: 299 cases) was conducted using the Microenvironment Cell Populations-counter (MCP-counter) algorithm [35] to quantify absolute infiltration levels of eight immune cell types (CD8+ T cells, CD4+ T cells, B cells, NK cells, macrophages, dendritic cells, mast cells, and neutrophils) and two stromal cell types (fibroblasts and endothelial cells). This evidence concerns the gene CD4 and ovarian carcinoma.
