Platinum-based chemotherapy inflames the ovarian carcinoma microenvironment through cellular senescence

Abstract

Epithelial ovarian carcinoma (EOC) is virtually insensitive to immune checkpoint inhibitors (ICIs). Recent findings from an innovative mouse model of EOC demonstrate that senescence induction underlies the increased sensitivity of homologous recombination-defective EOCs to platinum-based chemotherapy as it initiates tumor infiltration by immune effector cells coupled to restored sensitivity to ICIs.
