Abstract
BACKGROUND Approximately 3/4 of ovarian cancers are diagnosed in advanced stages, with the high-grade epithelial ovarian carcinoma (EOC) accounting for 90% of the cases. EOC present high genomic instability and somatic loss-of-function variants in genes associated with homologous recombination mutational repair pathway (HR), such as BRCA1 and BRCA2, and in TP53. The identification of germline variants in HR genes in EOC is relevant for treatment of platinum resistant tumors and relapsed tumors with therapies based in synthetic lethality such as PARP inhibitors. Patients with somatic variants in HR genes may also benefit from these therapies. In this work was analyzed the frequency of somatic variants in BRCA1, BRCA2, and TP53 in an EOC cohort of Brazilian patients, estimating the proportion of variants in tumoral tissue and their association with progression-free survival and overall survival. METHODS The study was conducted with paired blood/tumor samples from 56 patients. Germline and tumoral sequences of BRCA1, BRCA2, and TP53 were obtained by massive parallel sequencing. The HaplotypeCaller method was used for calling germline variants, and somatic variants were called with Mutect2. RESULTS A total of 26 germline variants were found, and seven patients presented germline pathogenic or likely pathogenic variants in BRCA1 or BRCA2. The analysis of tumoral tissue identified 52 somatic variants in 41 patients, being 43 somatic variants affecting or likely affecting protein functionality. Survival analyses showed that tumor staging was associated with overall survival (OS), while the presence of somatic mutation in TP53 was not associated with OS or progression-free survival. CONCLUSION Frequency of pathogenic or likely pathogenic germline variants in BRCA1 and BRCA2 (12.5%) was lower in comparison with other studies. TP53 was the most altered gene in tumors, with 62.5% presenting likely non-functional or non-functional somatic variants, while eight 14.2% presented likely non-functional or non-functional somatic variants in BRCA1 or BRCA2.

Abstract
Germline pathogenic variants of BRCA1 or BRCA2 cause hereditary breast and ovarian cancer syndromes. The present study investigated the participants' understanding and awareness of germline BRCA1/2 pathogenic variants before genetic counseling, the expectations and obstacles for genetic testing from the perspective of participants and their families, and their attitudes towards genetic testing after counseling. In this single-country, multicenter, non-interventional, patient-reported outcome study, untested cancer patients and their families who visited genetic counseling clinics or who wanted to receive pre-test genetic counseling were eligible to fill in the questionnaire after pre-test counseling for germline BRCA1/2 testing. Demographic information, clinical characteristics, and information collected from the questionnaires, including the understanding of BRCA1/2 pathogenic variants before genetic counseling, understanding of BRCA1/2 pathogenic variants and feelings after genetic counseling, willingness to share results of genetic testing with family, and willingness to receive genetic testing, were summarized using descriptive statistics. A total of 88 participants were enrolled. The proportion of slight understanding of BRCA1/2 pathogenic variants increased from 11.4% to 67.0%, and the proportion of full understanding increased from 0% to 8.0%. After genetic counseling, most participants were willing to undergo genetic testing (87.5%) and share the results with their families (96.6%). The main factors that may affect participants' willingness to undergo BRCA1/2 testing were management (61.2%) and testing costs (25.9%). After pre-test counseling, there was a high acceptance of BRCA1/2 testing and in-family information sharing in Taiwanese patients with cancer and their families, which may serve as a reference for implementing genetic counseling in Taiwan.

Abstract
The diagnosis, histomolecular classes of breast cancers (luminal A, luminal B, HER2-enriched, and basal-like), and accurate prediction of prognosis are commonly determined using morphological and phenotypical analyses in clinical practice worldwide. Therapeutic strategies are mostly based on the disease stage and molecular subclasses of breast cancer. Targeted therapies, such as anti-HER2s, poly-ADP ribose polymerase inhibitors or, to a lesser extent, phosphatidylinositol 3 kinase inhibitors, have substantially improved breast cancer patient prognosis over the past decades. Human epidermal growth factor receptor 2 (HER2) overexpression is widely determined based on immunohistochemistry, while next-generation sequencing (NGS) is currently employed to assess the presence of molecular alterations, including breast cancer gene 1 (BRCA1) and 2 or phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) mutations, which are targets of these new approved therapies. In addition, next-generation sequencing (NGS) can aid the pathologist in challenging situations, such as a diagnostic workup for a metastatic carcinoma in lymph nodes of unknown origin, differential diagnosis of spindle cell tumourtumor in the breast between metaplastic carcinoma, malignant PT and sarcoma, o, as well as determining relatedness between primary breast cancers and recurrences. NGS offers a powerful tool that enables the pathologist to combine morphological analyses together with molecular alterations in challenging diagnostic situations.

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 BRCA‐associated breast cancers tend to have distinctive features compared to sporadic breast cancers; further characterization can aid in optimizing treatment. Methods The study evaluated a patient cohort with early‐stage estrogen receptor positive, HER2 negative invasive breast cancer who had Oncotype DX Breast Recurrence Score® analysis and genetic testing for hereditary breast and ovarian cancer syndrome. Data on patients and their breast cancers with outcomes were collected and analyzed. Results 745 patients were included, of whom 33 had pathogenic BRCA mutations (8 BRCA1, 25 BRCA2). Patients with BRCA mutations were younger and received more adjuvant chemotherapy, but less endocrine therapy and radiation therapy. BRCA‐associated breast cancers had less progesterone receptor expression, higher nuclear grade, and higher Oncotype DX Breast Recurrence Scores® with median Recurrence Score® 29, compared to 16 in cancers without mutations (p < 0.0001). Breast cancer recurrence developed in 18% of patients with BRCA mutations and 9% of patient without mutations, although multivariate analysis of relapse‐free survival was not significant, HR 1.519 (95% confidence interval [CI] 0.64–3.58; p = 0.3401). After adjusting for Recurrence Score®, overall survival by BRCA status was improved HR 0.448 (95% CI 0.06–3.34; p = 0.4333). Conclusions BRCA‐associated early‐stage hormone receptor‐positive breast cancers have higher Oncotype DX Breast Recurrence Score® compared to those without mutations. BRCA status did not significantly impact relapse‐free survival and overall survival. Larger clinical trials are needed to further assess the findings, and if confirmed, could impact clinical management of BRCA‐associated breast cancers.

Abstract
BACKGROUND A higher risk for breast and ovarian cancer has been reported in BRCA carriers and prophylactic surgeries are proposed to reduce this risk. This retrospective cohort study has evaluated the indication of BRCA1/2 genetic tests in Iranian women and the rate of women's acceptance of prophylactic surgeries recommended by the surgeon. METHODS Medical records of 147 high-risk women according to NCCN clinical practice guidelines who referred for BRCA mutations testing were assessed. Individual information, indications for BRCA1/2 genetic testing and their results, physician recommendations, and type of accepted surgery were registered. To evaluate the current status of women an active visit follow-up every six months was conducted. RESULTS The mean age of women was 43.40 ± 10.94 and the median follow-up time was 1.92 years. Genetic test results showed 49(33.3%) women were positive for either BRCA1/2 mutations. Although the occurrence of breast cancer younger than 40 was the most common indication for genetic tests (26.5%), positive breast cancer history in first-degree relatives and two relatives younger than 50 was the most common indications with positive results. The rate of acceptance of prophylactic mastectomy and bilateral salpingo-oophorectomy was (14.3% and 34.7%) in BRCA mutation carriers. CONCLUSION If the onset of breast cancer at a young age (less than 40) will be the only indication for a BRCA analysis, the rate of a positive result (12.8%) is very low. Further studies are warranted to evaluate the age limit for genetic testing in our country. Prophylactic mastectomy acceptance is very low in BRCA1/2 carriers in our centers.

Abstract
The vast majority of studies assessing communication of BRCA1/2 results with relatives and family uptake of BRCA1/2 testing have been conducted in Western societies, and a dearth of studies have been conducted in Asia among relatives of diverse carriers of pathogenic BRCA1/2 germline variants. This study aimed to present rates of BRCA1/2 result disclosure by probands and probands' motivators and barriers of family communication and predictive testing uptake among eligible relatives. It also examined patterns of disclosure and testing uptake among different types of relatives. Eighty-seven carriers with either breast or ovarian cancer, who had previously been found to be carriers of a pathogenic variant in BRCA1/2, were interviewed over the phone using a semi-structured interview guide. Fifty-six percent of patients were Chinese, 21% were Indian, and 23% were Malay. It was found that 62.0% of eligible first- and second-degree relatives were informed by the proband about the testing result and that 11.5% of eligible first- and second-degree relatives had genetic testing. First-degree relatives were more likely to have been informed and tested compared to second-degree relatives, as were sisters compared to brothers. The low rates of family communication and testing uptake documented in this study suggest that interventions should focus on encouraging probands to inform male and second-degree relatives and targeting such relatives to increase informed decisions and accessibility to testing. Promotion strategies should be culturally sensitive to optimize outcomes.

Abstract
OBJECTIVES To report the baseline results of a longitudinal psychosocial study that forms part of the IMPACT study, a multi-national investigation of targeted prostate cancer (PCa) screening among men with a known pathogenic germline mutation in the BRCA1 or BRCA2 genes. PARTICPANTS AND METHODS Men enrolled in the IMPACT study were invited to complete a questionnaire at collaborating sites prior to each annual screening visit. The questionnaire included sociodemographic characteristics and the following measures: the Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale (IES), 36-item short-form health survey (SF-36), Memorial Anxiety Scale for Prostate Cancer, Cancer Worry Scale-Revised, risk perception and knowledge. The results of the baseline questionnaire are presented. RESULTS A total of 432 men completed questionnaires: 98 and 160 had mutations in BRCA1 and BRCA2 genes, respectively, and 174 were controls (familial mutation negative). Participants' perception of PCa risk was influenced by genetic status. Knowledge levels were high and unrelated to genetic status. Mean scores for the HADS and SF-36 were within reported general population norms and mean IES scores were within normal range. IES mean intrusion and avoidance scores were significantly higher in BRCA1/BRCA2 carriers than in controls and were higher in men with increased PCa risk perception. At the multivariate level, risk perception contributed more significantly to variance in IES scores than genetic status. CONCLUSION This is the first study to report the psychosocial profile of men with BRCA1/BRCA2 mutations undergoing PCa screening. No clinically concerning levels of general or cancer-specific distress or poor quality of life were detected in the cohort as a whole. A small subset of participants reported higher levels of distress, suggesting the need for healthcare professionals offering PCa screening to identify these risk factors and offer additional information and support to men seeking PCa screening.

Abstract
BACKGROUND Historically, three founder mutations in the BRCA1/2 (OMIM 113705; OMIM 600185) genes have been the focus of cancer risks within the Ashkenazi Jewish (AJ) population. However, there are several additional mutations associated with increased susceptibility to cancer in individuals of AJ ancestry. METHODS We report three patients who exemplify the need to keep these additional founder mutations in mind when pursuing hereditary cancer genetic testing of individuals in this population. All gene sequences in this paper were aligned to reference sequences based on human genome build GRCh37/UCSC hg19. RESULTS review of the literature discusses that the combined risk is 12.36%-20.83% forhaving 1 of the 10 hereditary cancer AJ founder mutations in the BRCA1, BRCA2, CHEK2 (OMIM 604373), APC (OMIM 611731), MSH2 (OMIM 609309), MSH6 (OMIM 600678), and GREM1 (OMIM 603054) genes for individuals of AJ ancestry. CONCLUSION We recommend testing for all 10 of these AJ founder cancer susceptibility mutations for individuals within this population as standard screening in order to ensure appropriate cancer risk management and cascade testing.

RESULTS Overall, 38% (58/152) of eligible GPs and 70% (176/252) of eligible patients were surveyed. Although 81% of GPs collected the family history, only 24% considered that they know criteria indicating genetics consultation and 39% sufficient knowledge of BRCA1/2 guidelines to answer patients' questions. Twelve% of GPs were aware of the French national guidelines. Among unsatisfied patients, 40% felt that their GP was able to answer (moderately, sufficiently, or completely) specific questions about BRCA1/2 care as compared with 81% in satisfied patients. Only 33% of GPs reported being informed directly by the geneticist about the patients' results. GPs' main expectations for their role in BRCA1/2 carrier care were psychological support and informing relatives about screening (72% and 71%, respectively), which contrasts with the perceptions of patients, who mainly requested medical advice for BRCA1/2-related care (51%). CONCLUSION There is an important need for GP training and enhancing interactions between GPs and geneticists to improve the GP's role in BRCA1/2 screening and management.
