Summary
Brief summary (as posted)
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.

[]Primary outcomes (2)
- measure
- Loss of heterozygosity (LOH) score in the primary and recurrent ovarian cancer
- timeFrame
- Through study completion, an average of 1 year]
- description
- The LOH score is a scale describing the genomic loss of heterozygosity status in the primary or recurrent tumor of an ovarian cancer patient. The score is determined by analyzing more than 3500 SNPs spaced at 1Mb intervals across the genome on the FoundationOne CDx test and extrapolating an LOH profile, excluding arm and chromosome-wide LOH segments. The score is summarized as the percentage of the genome with LOH regions.
- measure
- Homologous recombination deficiency (HRD) status
- timeFrame
- Through study completion, an average of 1 year
- description
- The HRD status for primary or recurrent tumor in a patient is considered according to the LOH score and genomic mutation status of BRCA1 and BRCA2 genes in the sample. A sample with LOH≥16%，and/or with genomic mutation in BRCA1 or BRCA2 gene, is defined as HRD positive. Otherwise, a sample with LOH\<16% and wild type BRCA1/BRCA2 genes is defined as HRD negative.
