NCT04651920

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Homologous recombination deficiency (HRD) score

    The HRD score for individual patient is a scale describing her HRD status. The score model is calculated by the analysis for three types of important molecular mechanism: loss of heterozygosity (LOH), telomere allele imbalance (TAI) and large-scale state transitions (LST). The minimum value is 0, but the maximun value is not available. Higher scores mean more sensitivity to poly-ADP-ribose polymerase inhibitor.

    Two years

Secondary Outcomes (2)

  • Progression-free survival

    Five years

  • Overall survival

    Five years

Study Arms (2)

Epithelial ovarian cancer patients sensitive to platinum based chemotherapy

Genetic: Evaluation of homologous recombination deficiency score

Epithelial ovarian cancer patients resistant to platinum based chemotherapy

Genetic: Evaluation of homologous recombination deficiency score

Interventions

Evaluation of homologous recombination deficiency score which is based on the loss of heterozygosity (LOH), telomere allele imbalance (TAI) and large-scale state transitions (LST)
