Abstract
BACKGROUND Mountain areas of the North Caucasus host several large ethnic communities that have preserved their national identity over the centuries. METHODS This study involved high-grade serous ovarian cancer (HGSOC) and breast cancer (BC) patients from Dagestan (HGSOC: 37; BC: 198), Kabardino-Balkaria (HGSOC: 68; BC: 155), North Ossetia (HGSOC: 51; BC: 104), Chechnya (HGSOC: 68; BC: 79), Ingushetia (HGSOC: 19; BC: 103), Karachay-Cherkessia (HGSOC: 13; BC: 47), and several Armenian settlements (HGSOC: 16; BC: 101). The group of BC patients was enriched by young-onset and/or family history-positive and/or bilateral and/or receptor triple-negative cases. The entire coding region of BRCA1, BRCA2, PALB2, and ATM genes was analyzed by next-generation sequencing. RESULTS A significant contribution of BRCA1/2 pathogenic variants (PVs) to HGSOC and BC development was observed across all North Caucasus regions (HGSOC: 19-39%; BC: 6-13%). Founder alleles were identified in all ethnic groups studied, e.g., BRCA1 c.3629_3630delAG in Chechens, BRCA2 c.6341delC in North Ossetians, BRCA2 c.5351dupA in Ingush, and BRCA1 c.2907_2910delTAAA in Karachays. Some BRCA1/2 alleles, particularly BRCA2 c.9895C > T, were shared by several nationalities. ATM PVs were detected in 14 patients, with c.1673delG and c.8876_8879delACTG alleles occurring twice each. PALB2 heterozygosity was observed in 5 subjects, with one variant seen in 2 unrelated women. CONCLUSION This study adds to the evidence for the global-wide contribution of BRCA1/2 genes to HGSOC and BC morbidity, although the spectrum of their PVs is a subject of ethnicity-specific variations. The data on founder BRCA1/2 alleles may be considered when adjusting the BRCA1/2 testing procedure to the ethnic origin of patients.

Abstract
We report a case of rare and aggressive ovarian carcinosarcoma with a germline pathogenic BRCA2 variant. A patient with a history of breast cancer who developed an inflammatory ovarian tumor with peritonitis carcinomatosis involving the appendix suffered from cachexia. Following three cycles of weekly paclitaxel and carboplatin chemotherapy, emergency surgery was required owing to sepsis. Bilateral salpingo-oophorectomy, total hysterectomy, appendectomy, and small intestine adhesiolysis were performed. Histologically, the tumor comprised an admixture of carcinomatous and sarcomatous components, with involvement of the appendix, which had caused perforation and abscess formation. The final diagnosis was ovarian carcinosarcoma with a germline pathogenic BRCA2 variant, c.658_659del (p.Val220fs). The patient responded completely to adjuvant chemotherapy. A combination of chemotherapy and surgery might be beneficial to patients with ovarian carcinosarcoma and germline pathogenic BRCA2 variants with a poor general condition. This is the first report of ovarian carcinosarcoma with a germline pathogenic BRCA2 variant that responded favorably to chemotherapy.

Gynecol Oncol 2023; 170:234-240. [PMID: 36724586 DOI: 10.1016/j.ygyno.2022.12.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Revised: 12/20/2022] [Accepted: 12/22/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVE The real-world management of patients with non-BRCA, homologous recombination repair pathway variants with increased or uncertain risks of ovarian cancer is unknown. The objective was to determine the adoption of risk-reducing salpingo-oophorectomy (RRSO) for carriers of variants with increased or uncertain risks of ovarian cancer beyond BRCA. METHODS This was a retrospective cohort study of patients at three hospitals with non-BRCA, homologous recombination repair pathway variants with increased risk (BRIP1, RAD51C, RAD51D) and uncertain risk (ATM, BARD1, NBN, PALB2) of ovarian cancer. Outcomes of interest were adoption of RRSO and factors associated with adoption of RRSO. Wilcoxon rank-sum, chi-square, and logistic regression were performed with p < 0.05. RESULTS Of 318 patients, 76 (24%) had pathogenic variants with increased risks of ovarian cancer (BRIP1, 45; RAD51C, 20; RAD51D, 11), and 242 (76%) had variants with uncertain risks of ovarian cancer (ATM, 145; PALB2, 69; NBN, 23; BARD1, 5). Of 64 patients eligible for RRSO by National Comprehensive Cancer Network (NCCN) criteria or family history, 31 (48%) underwent RRSO. Among eligible patients who did not undergo RRSO, 24 (73%) were not referred for gynecologic oncology consultation. Older age at testing (adjusted odds ratio [aOR] 1.08, 95% confidence interval [CI] 1.03-1.13) and referral to gynecologic oncology (aOR 33.48, CI 8.10-138.39) were associated with increased adoption of RRSO when adjusting for personal and family history of breast and ovarian cancer. CONCLUSION Half of RRSO-eligible patients by NCCN criteria beyond BRCA did not undergo RRSO. Opportunities exist for improving education to increase referrals to facilitate RRSO for these patients.

Founder vs. non-founder BRCA1/2 pathogenic alleles: the analysis of Belarusian breast and ovarian cancer patients and review of other studies on ethnically homogenous populations. Fam Cancer 2023; 22:19-30.

Abstract
The spectrum of BRCA1/2 mutations demonstrates significant interethnic variations. We analyzed for the first time the entire BRCA1/2 coding region in 340 Belarusian cancer patients with clinical signs of BRCA1/2-related disease, including 168 women with bilateral and/or early-onset breast cancer (BC), 104 patients with ovarian cancer and 68 subjects with multiple primary malignancies involving BC and/or OC. BRCA1/2 pathogenic alleles were detected in 98 (29%) women, with 67 (68%) of these being represented by founder alleles. Systematic comparison with other relevant studies revealed that the founder effect observed in Belarus is among the highest estimates observed worldwide. These findings are surprising, given that the population of Belarus did not experience geographic or cultural isolation throughout history.

Abstract
Coding sequences of BRCA1, BRCA2, ATM, TP53, and PALB2 genes were analyzed in 68 consecutive Chechen patients with high-grade serous ovarian cancer (HGSOC). Pathogenic BRCA1/2 variants were identified in 15 (22%) out of 68 HGSOC cases. Nine out of ten patients with BRCA1 pathogenic alleles carried the same deletion (c.3629_3630delAG), and three out of five BRCA2 heterozygotes had Q3299X allele. The analysis of 49 consecutive patients with triple-negative breast cancer (TNBC) revealed 3 (6%) additional BRCA1 heterozygotes. All women with BRCA1 c.3629_3630delAG allele also carried linked c.1067G>A (Q356R) single nucleotide polymorphism, indicating that this is a genuine founder variant but not a mutational hotspot. An ATM truncating allele was detected in one HGSOC patient. There were no women with TP53 or PALB2 germline alterations. Genetic analysis of non-selected HGSOC patients is an efficient tool for the identification of ethnicity-specific BRCA1/2 pathogenic variants.

Abstract
Objective To investigate the prevalence and spectrum of BRCA1 and BRCA2 mutations in Chinese Hakka patients with breast and ovarian cancer. Methods A total of 1,664 breast or ovarian cancer patients were enrolled for genetic testing at our hospital. Germline mutations of the BRCA gene were analysed by next-generation sequencing, including the coding regions and exon intron boundary regions. Results The 1,664 patients included 1,415 (85.04%) breast cancer patients and 245 (14.72%) ovarian cancer patients, while four (0.24%) patients had both the breast and ovarian cancers. A total of 151 variants, including 71 BRCA1 variants and 80 BRCA2 variants, were detected in the 234 (14.06%) patients. The 151 variants included 58 pathogenic variants, 8 likely pathogenic variants, and 85 variants of unknown significance (VUS). A total of 56.25% (18/32) and 65.38% (17/26) of pathogenic variants (likely pathogenic variants are not included) were distributed in exon 14 of BRCA1 and exon 11 of BRCA2, respectively. The most common pathogenic variants among this Hakka population are c.2635G > T (p.Glu879*) (n = 7) in the BRCA1 gene and c.5164_5165del (p.Ser1722Tyrfs*4) (n = 7) in the BRCA2 gene among the Hakka population. A hotspot mutation in the Chinese population, the BRCA1 c.5470_5477del variant was not found in this Hakka population. The prevalence and spectrum of variants in the BRCA genes in the Hakka patients are different from that in other ethnic groups. Conclusions The most common pathogenic variant in this population is c.2635G > T in the BRCA1 gene, and c.5164_5165delAG in the BRCA2 gene in this population. The prevalence and spectrum of variants in the BRCA1 and BRCA2 genes in the Hakka patients from southern China are different from those in other ethnic groups.
