Overview

This project intends to evaluate the sensitivity of different Homologous Recombination Deficiency (HRD) score to Poly(ADP-ribose) polymerase inhibitor (PARPi) by retrospectively analyzing the tissue samples of patients with ovarian cancer using PARPi, and to determine the cut off value of the HRD score algorithm suitable for the Chinese population, so as to provide evidence for the role of PARPi in ovarian cancer. The screening of the beneficiaries of maintenance therapy provides precise guidance and can be used as a reference for other cancer types.
