Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The association between homologous recombination (HR) gene mutations and homologous recombination deficiency (HRD) status in Chinese epithelial ovarian cancer (EOC) patients is little known. This study would recruit 400 Chinese EOC patients with known targeted gene mutations via a multi-panel testing of 27 genes, including BRCA1/BRCA2. All patients accept evaluation of HRD model, which is based on the loss of heterozygosity (LOH), telomere allele imbalance (TAI) and large-scale state transitions (LST). The mutated genes, HRD score model and their relationship with the prognosis, would provide a full description of for the Chinese EOC patients, and a potential explanation of platinum-resistance in such population.
