Variance of HRD From Paired Ovarian Cancer

Variance of HRD From Primary to Recurrent in High-grade Serous Ovarian Cancer

Homologous recombination deficiency (HRD) is an important biomarker of poly (ADP-ribose) polymerase inhibitor (PARPi) in patients with high-grade serous ovarian cancer (HGSOC). The stability of HRD in the recurrent HGSOC and its primary pair remains unknown.

This study intends to perform HRD testing of ovarian cancer in the recurrent HGSOC and its primary pair, furtherly correlate HRD status and clinical characteristics in the recurited population.

Inclusion Criteria:

1. Subjects join the study voluntarily and sign informed consent;
2. Female subjects are older than 18 years;
3. ECOG(Eastern Cooperative Oncology Group) physical status score is 0-2;
4. Life expectancy≥3 months;
5. Histologically confirmed FIGO(International Federation of Gynecology and Obstetrics ) III/IV ovarian cancer, fallopian tube cancer, or primary peritoneal cancer; Participants must have high-grade serous histology

Exclusion Criteria:

1. Personnel involved in the formulation or implementation of the research plan;
2. The subjects had other malignant diseases in past 2 years, except skin squamous cell carcinoma, basal-like carcinoma, breast intraductal carcinoma in situ, or cervical carcinoma in situ;
