Notably, OC patients in the low‐TAS group demonstrated elevated infiltration of various immune cells, including active dendritic cells (ADC), B cells, CD8+ T cells, dendritic cells (DCs), immature dendritic cells (iDC), neutrophils, NK cells, plasmacytoid dendritic cells (pDCs), helper T cells (Th1/Th2), tumour‐infiltrating lymphocytes (TILs) and Tregs (Figure 8B,C). This evidence concerns the gene CD8A and neoplasm.
