Homologous Recombination Deficiency in Chinese Ovarian Cancer Patients


Homologous recombination deficiency (HRD) is an important molecular biomarker for Poly (ADP-ribose) polymerase inhibitors (PARPi) which is a significant progress in the treatment of ovarian cancer. However, the proportion of HRD positive in real world and relationship of HRD status with PARPi in Chinese ovarian cancer patients remains unknown.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: September 2022

Detailed Description

This study intends to perform HRD testing of ovarian cancer in real world from China and correlate HRD status and clinical characteristics with therapeutic outcomes.


  • Drug: PARP inhibitor
    • Ovarian/fallopian tube/primary peritoneal cancer patients with PARP inhibitors according to the NCCN guideline and their instructions

Arms, Groups and Cohorts

  • ovarian/fallopian tube/primary peritoneal cancer patients
    • ovarian/fallopian tube/primary peritoneal cancer patients treated with PAPRi for more than four weeks

Clinical Trial Outcome Measures

Primary Measures

  • Overall Response Rate (ORR)
    • Time Frame: Through study completion, an average of 1 year
    • ORR is defined as the proportion of participants achieving complete response (CR) or partial response (PR) as assessed by RECIST1.1.
  • Progression Free Survival (PFS)
    • Time Frame: Through study completion, an average of 1 year
    • PFS is defined as the time in months from the date of first study drug administration to the date of first documentation of progressive disease (PD) or death as assessed by RECIST1.1.
