Germline mutations of breast cancer susceptibility genes through expanded genetic analysis in unselected Colombian patients. Hum Genomics 2024; 18:68. [PMID: 38890714 PMCID: PMC11184794 DOI: 10.1186/s40246-024-00623-7] [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: 02/05/2024] [Accepted: 05/15/2024] [Indexed: 06/20/2024] Open
Abstract
BACKGROUND In Colombia and worldwide, breast cancer (BC) is the most frequently diagnosed neoplasia and the leading cause of death from cancer among women. Studies predominantly involve hereditary and familial cases, demonstrating a gap in the literature regarding the identification of germline mutations in unselected patients from Latin-America. Identification of pathogenic/likely pathogenic (P/LP) variants is important for shaping national genetic analysis policies, genetic counseling, and early detection strategies. The present study included 400 women with unselected breast cancer (BC), in whom we analyzed ten genes, using Whole Exome Sequencing (WES), know to confer risk for BC, with the aim of determining the genomic profile of previously unreported P/LP variants in the affected population. Additionally, Multiplex Ligation-dependent Probe Amplification (MLPA) was performed to identify Large Genomic Rearrangements (LGRs) in the BRCA1/2 genes. To ascertain the functional impact of a recurrent intronic variant (ATM c.5496 + 2_5496 + 5delTAAG), a minigene assay was conducted. RESULTS We ascertained the frequency of P/LP germline variants in BRCA2 (2.5%), ATM (1.25%), BRCA1 (0.75%), PALB2 (0.50%), CHEK2 (0.50%), BARD1 (0.25%), and RAD51D (0.25%) genes in the population of study. P/LP variants account for 6% of the total population analyzed. No LGRs were detected in our study. We identified 1.75% of recurrent variants in BRCA2 and ATM genes. One of them corresponds to the ATM c.5496 + 2_5496 + 5delTAAG. Functional validation of this variant demonstrated a splicing alteration probably modifying the Pincer domain and subsequent protein structure. CONCLUSION This study described for the first time the genomic profile of ten risk genes in Colombian women with unselected BC. Our findings underscore the significance of population-based research, advocating the consideration of molecular testing in all women with cancer.

Abstract
BACKGROUND Previous studies in the general population observed that compared with non-Hispanic White women, Pacific Islander and Black women have higher age-adjusted mortality rates from epithelial ovarian cancer (EOC), while Asian American patients have lower mortality. We investigated whether race and ethnicity is associated with differences in EOC survival in a United States Military population where patients have equal access to healthcare. METHODS This retrospective study included women diagnosed with EOC between 2001 and 2018 among Department of Defense beneficiaries. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards regression models adjusting for age and year of diagnosis, histology and stage. RESULTS In our study population of 1230 invasive EOC cases (558 non-Hispanic White, 74 non-Hispanic Black, 73 Asian, 30 Pacific Islander and 36 Hispanic cases), 63% of the women died (all-cause death) after a mean = 4.8 years (SD = 4.1) of follow-up following diagnosis. Compared with non-Hispanic White cases, Asian cases had better overall survival, HR = 0.76 (95% CI = 0.58-0.98), whereas there were no differences in survival for other racial and ethnic groups. CONCLUSIONS These findings highlight the need to investigate how differences in access to healthcare may influence observed racial and ethnic disparities for EOC.

Abstract
Breast cancer is the most common cancer in women and is cause mortality in many countries. The purpose of this article is to determine the BRCA1 BRCA2 gene mutation polymorphisms, as well as to determine the clinical, histopathological and prognostic characteristics in patients with breast cancer in the western region of Kazakhstan. A study was conducted on the genotyping of 278 patients in the MC ZKMU Marat Ospanov with an established diagnosis of breast cancer, which revealed that out of 278 patients, of 3 cases were identified. In the age category up to 50 years, 70 cases were detected (25.1%) after 50 years 208 cases were identified (74%). Number of patients in stage I was 20 (7.1%) in stage second 204 (73%) and in stage third 54 (19%). By tumor size, 30(10%) cases were T1, 194 (69%) cases were T2, 35 (12.5%) cases were T3, and 19 cases were T4 (6.8%). According to metastasis of the lymph nodes, no lymph nodes were detected in 107 (38%) cases, 1-3 L/n (Lymph Nodes) in 95 (34%) cases, 4-9 L/n in 12 (4%) cases, 10 L/n in 4 (1.4%) cases and unknown cases was 60 (21%). In 99.6% of patients no distant metastases was detected. According to the molecular classification of the tumor, Luminal type A is most found in this study 147 (52.8%), then Luminal type B 57 (20.5%), HER-2 positive 26 (9.3%) and Triple negative 48 (17.2%). By ethnicity the Kazakh race is 182 (65%) the Caucasian race was 96 (34%). Large population screening studies involving all BRCA1/2 polymorphisms are required to confirm the penetrance, frequency and significance of a wide range of variations of BRCA1/2 genes in the Kazakh population.

Abstract
OBJECTIVE To study the anticipation phenomenon among hereditary breast cancer patients, by evaluating trends in age at diagnosis and phenotype of breast cancer across two successive generation pairs of BRCA1/2 mutation carriers/non-carriers with breast cancer after reports of an earlier age of diagnosis in successive generations among BRCA1/2 mutation carrier families. METHOD A retrospective cohort study. Patient characteristics, pathologic data and survival were compared between mothers and daughters and between carriers and non-carriers. RESULTS Overall, 126 patients were found, who formed 67 pairs of mothers and daughters diagnosed with breast cancer and genetically tested for BRCA mutations. Age at diagnosis was significantly younger in the daughter versus mother generation, in both groups of BRCA carriers/non-carriers. Tumor characteristics were not different between mothers and daughters. Survival analysis revealed a not significant better outcome for the daughter generation versus the mother generation. CONCLUSIONS Breast cancer appeared to be diagnosed at an earlier age in successive generations among BRCA mutation carriers and non-carriers. The fact that we also observed a downshift at age of diagnosis in non-carrier pairs emphasizes that other factors (environmental, lifestyle, or social) may influence the age at diagnosis.

Abstract
BACKGROUND Cancer is the leading cause of death in Asian Americans (AA), the fastest-growing U.S. population group. Despite heterogeneity in socioeconomic status and health behaviors by ethnicity, few studies have assessed cancer outcomes across AA ethnic groups. We examined differences in gynecologic cancer mortality between AA ethnic groups and non-Hispanic Whites (NHW). METHODS Using the Surveillance, Epidemiology, and End Results database, we identified ovarian (n=69,113), uterine (n=157,340), and cervical cancer cases (n=41,460) diagnosed from 1991-2016. Competing risk regression was used to compare cancer-specific mortality for AAs by ethnicity, using NHW as the reference population. RESULTS In adjusted analyses, AAs had a lower risk of ovarian (hazard ratio [HR]: 0.90, 95% CI: 0.86-0.94) and cervical cancer death (HR: 0.80, 95% CI: 0.75-0.87) than NHWs, with stronger associations among those {greater than or equal to}50 years at diagnosis (HRovary: 0.87, 95% CI: 0.82-0.92; HRcervix: 0.74, 95% CI: 0.67-0.81). No overall difference was noted for uterine cancer death (HR: 1.03, 95% CI: 0.97-1.10); however, AAs <50 years at diagnosis had a higher risk of uterine cancer death than NHWs (HR: 1.26, 95% CI: 1.08-1.46). Patterns of cancer mortality were heterogeneous, with Filipino and Chinese women at the highest risk of uterine cancer death and Indian/Pakistani women at the lowest risk of ovarian and cervical cancer death. CONCLUSIONS There are significant differences in gynecologic cancer mortality between AAs and NHWs, with heterogeneity by AA ethnicity. IMPACT Disaggregated analysis of AA is needed to better understand the burden of gynecologic cancer and identify high-risk groups for cancer prevention efforts.

Abstract
The aim of the current analysis is to evaluate any differences of breast or ovarian cancer age at diagnosis between mothers and daughters carrying the c.3481_3491del11 mutation in the BRCA1 gene. A study cohort of 38 women carrying the c.3481_3491del11 mutation and affected by first breast or ovarian cancer who reported a first breast or ovarian cancer in their mother carrying the c.3481_3491del11 mutation, was identified in 37 different families including members with breast and/or ovarian cancer at the Oncology Institute of Lorraine. Twelve mothers underwent genetic testing. Twenty-five pairs of the 38 mothers-daughters pairs with c.3481_3491del11 mutation were affected by breast cancer and 13 pairs by ovarian cancer. Clinical and genetic data were collected from medical files and family pedigrees. Analyses were conducted for each cancer type. We investigated an early breast cancer detection effect due to early screening programs and also an increased breast tumor aggression. Since major improvements in breast cancer clinical management and imaging techniques appeared after 1980, we compared the age at breast cancer diagnosis and the age at death in mothers and daughters before and after 1980, first, in the group of women including mothers and daughters taken together and then in mothers and daughters separately. The mean age at breast cancer diagnosis was 45.28 ± 10.27 years in mothers and 39.80 ± 7.79 years in daughters (p = 0.026). The difference of age at ovarian cancer diagnosis in mother-daughter pairs was 8.62 ± 12.76 years (p = 0.032). When considering the group of women including mothers and daughters taken together, no significant difference of age at breast cancer diagnosis was found between women affected before 1980 and those affected after 1980 (p = 0.577). However, the age at death increased in these women after 1980 (p = 0.026). Comparison of age at breast cancer diagnosis in mothers and daughters separately, showed that daughters were affected at an earlier age after 1980 (p = 0.002). Daughters had a poor prognosis and died earlier than mothers after 1980. Our results may have reflected genetic anticipation in c.3481_3491del11 mutation breast and ovarian cancer families. In order to confirm our findings, a larger cohort would provide more precision to the difference of ages at breast or ovarian cancer diagnosis between mothers and daughters and more powerful statistical analyses. Increased aggression in daughters' tumors compared to those of mothers could be also considered as a parameter of genetic anticipation. Complete information on tumor profile and proliferation would allow us to study genetic anticipation by comparing the tumor phenotypes between mothers and daughters in the future.

Abstract
Purpose We performed exome sequencing in a breast cancer family without BRCA mutations. Materials and Methods A family that three sisters have a history of breast cancer was selected for analysis. There were no family members with breast cancer in the previous generation. Genetic testing for BRCA mutation was negative, even by the multiplex ligation-dependent probe amplification method. Two sisters with breast cancer were selected as affected members, while the mother of the sisters was a non-affected member. Whole exome sequencing was performed on the HiSeq 2000 platform with paired-end reads of 101 bp in the three members. Results We identified 19,436, 19,468, and 19,345 single-nucleotide polymorphisms (SNPs) in the coding regions. Among them, 8,759, 8,789, and 8,772 were non-synonymous SNPs, respectively. After filtering out 12,843 synonymous variations and 12,105 known variations with indels found in the dbSNP135 or 1000 Genomes Project database, we selected 73 variations in the samples from the affected sisters that did not occur in the sample from the unaffected mother. Using the Sorting Intolerant From Tolerant (SIFT), PolyPhen-2, and MutationTaster algorithms to predict amino acid substitutions, the XCR1, DLL1, TH, ACCS, SPPL3, CCNF, and SRL genes were risky among all three algorithms, while definite candidate genes could not be conclusively determined. Conclusion Using exome sequencing, we found 7 variants for a breast cancer family without BRCA mutations. Genetic evidence of disease association should be confirmed by future studies.

Abstract
OBJECTIVE To compare the racial differences in treatment and survival of Asian-Americans and White patients with epithelial ovarian cancer. METHODS Data were obtained from the Surveillance, Epidemiology, and End Results Program between 1988 and 2009 and analyzed using Chi-squared tests, Kaplan-Meier methods, and Cox regression analysis. RESULTS Of the 52,260 women, 3932 (7.5%) were coded as Asian, and 48,328 (92.5%) were White. The median age of Asians at diagnosis was 56 vs. 64 years for the Whites (p<0.001). Asians were more likely to undergo primary surgery, have an earlier stage of disease, have a diagnosis of a non-serous histology, and have lower grade tumors. The 5-year disease-specific survival (DSS) of Asians was higher compared to Whites (59.1% vs. 47.3%, p<0.001). On a subset analysis, Vietnamese, Filipino, Chinese, Korean, Japanese, and Asian Indian/Pakistani ethnicities had 5-year DSS of 62.1%, 61.5%, 61.0%, 59.0%, 54.6%, and 48.2%, respectively (p=0.015). On multivariate analysis, age at diagnosis, year of diagnosis, race, surgery, stage, and tumor grade were all independent prognostic factors for survival. Asians were further stratified to U.S. born versus those who were born in Asia and immigrated. Asian immigrants presented at a younger age compared to U.S. born Asians. Immigrants were found to have an improved 5-year DSS when compared to U.S. born Asians and Whites of 55%, 52%, and 48%, respectively (p<0.001). CONCLUSION Asians were more likely to be younger, undergo primary surgery, have an earlier stage of disease, non-serous histology, lower grade tumors, and higher survival.
