Povzetek: Objectives. Risk-reducing mastectomy (RRM) is one of key prevention strategies in female carriers of germline BRCA pathogenic/likely pathogenic variants (PV/LPV). We retrospectively investigated the rate, timing and longitudinal trends of bilateral RRM uptake and the incidence and types of cancers among unaffected BRCA carriers who underwent genetic counseling at the Institute of Oncology Ljubljana in Slovenia. Materials and Methods. Female BRCA carriers without personal history of cancer were included in the study. Clinical data on PV/LPV type, date of RRM, type of reconstructive procedure, occult carcinoma and histopathology results was collected and analyzed. Results. Of the 346 unaffected BRCA carriers (median age 43 years, 70% BRCA1, 30% BRCA2, median follow-up 46 months) who underwent genetic testing between October 1999 and December 2019, 25.1% had a RRM (range 35-50 years, median age at surgery 38 years). A significant difference in time to prophylactic surgery between women undergoing RRM only vs. women undergoing RRM combined with risk-reducing salpingo-oophorectomy was observed (22.6 vs 8.7 months, p=0.0009). We observed an upward trend in the annual uptake in line with the previously observed Angelina Jolie effect. In 5.7% of cases, occult breast cancer was detected. No women developed breast cancer after RRM. Women who did not opt for surgical prevention developed BRCA1/2-related cancers (9.3%). Conclusion. The uptake of RRM among unaffected BRCA carriers is 25.1% and is similar to our neighboring countries. No women developed breast cancer after RRM while women who did not opt for surgical prevention developed BRCA1/2 related cancers in 9.3% of cases. The reported data may provide meaningful aid for carriers when deciding on an optimal prevention strategy.

Povzetek: Detection of germline and somatic pathogenic/likely pathogenic variants (PV/LPV) in BRCA genes is at the moment a prerequisite for use of PARP inhibitors in different treatment settings of different tumors. The aim of our study was to determine the most appropriate testing workflow in epithelial ovarian cancer (EOC) patients using germline and tumor genotyping of BRCA and other hereditary breast and/or ovarian cancer (HBOC) susceptibility genes. Consecutive patients with advanced non-mucinous EOC, who responded to platinum-based chemotherapy, were included in the study. DNA extracted from blood and FFPE tumor tissue were genotyped using NGS panels TruSightCancer/Hereditary and TruSight Tumor 170. Among 170 EOC patients, 21.8% had BRCA germline or somatic PV/LPV, and additionally 6.4% had PV/LPV in other HBOC genes. Sensitivity of tumor genotyping for detection of germline PV/LPV was 96.2% for BRCA genes and 93.3% for HBOC genes. With germline genotyping-only strategy, 58.8% of HBOC PV/LPV and 68.4% of BRCA PV/LPV were detected. By tumor genotyping-only strategy, 96.1% of HBOC PV/LPV and 97.4% of BRCA PV/LPV were detected. Genotyping of tumor first, followed by germline genotyping seems to be a reasonable approach for detection of PV/LPV in breast and/or ovarian cancer susceptibility genes in non-mucinous EOC patients.
