NBDC Research ID: hum0030.v4
SUMMARY
Aims: To clarify the biological difference between clear cell carcinoma and other histological subtypes in ovarian carcinomas by comparing copy number variants, and to identify molecular subtypes and carcinogenesis in clear cell ovarian carcinomas by whole-exome sequencing and RNA-sequencing. Then, characterize high-grade serous carcinomas by NGS-based, integrative genomic analyses, with focus on homologous recombination deficiency, molecular subtypes, and prognostic factors and effectiveness of PARP inhibitor. Based on the results of whole-exome sequencing, an investigator-initiated, phase 2 clinical trial will be conducted to evaluate the efficacy and safety of the PARP inhibitor olaparib in HRD-positive cases.
Methods:
Copy Number Variation Analysis: Gene Chip Human Mapping 250K Nsp Arrays were used for detecting the signal intensity of about 260 thousands SNPs and intensities of ovarian clear cell carcinoma were compared to the ones of non-carcinoma.
Whole Exome sequencing and RNA-seq
Methylation array and Expression array
Participants/Materials: Ovarian cancer: 57 cases (12 endometrioid carcinoma) + 111 cases + 31 + 189 cases
