Abstract:

Ovarian cancer is one of the three major gynecological malignancies and the most lethal malignancy of female reproductive system. At present, the main treatment methods for ovarian cancer are primary debulking surgery and platinum-based chemotherapy, but the recurrence rate and drug resistance rate remain high. In recent years, the development of tumor immunotherapy has progressed rapidly, especially the research on programmed death-1(PD-1) and programmed death-ligand 1 (PD-L1), which has been achieved on a variety of tumors. However, many clinical trials have found that PD-1/PD-L1 inhibitors alone are not effective in treating ovarian cancer. The poly (ADP-ribose) polymerase inhibitor (PARPi) is a type of targeted medicine that kills tumor cells through synthetic lethal effect. Recent studies have shown that PARPi has immunomodulatory effects in addition to its own cytotoxic effects, and can have a synergistic effect with PD-1/PD-L1 inhibitors, and the combination of the two can significantly improve patient prognosis. Therefore, this article reviews the research progress on the mechanism of action and clinical application of PD-1/PD-L1 inhibitor combined with PARPi in the treatment of ovarian cancer.
