IFNG and neoplasm: This observation may result from the ability of IFNγ to induce the secretion of NK‐ and T‐cell‐stimulatory cytokines by macrophages, as tumor‐infiltrating CD8+ T cells are clearly linked to a long overall survival (OS) of OC [64, 65, 66], as are effector memory CD8+ cells and NK cells in ascites [55, 56].
