BACKGROUND: Retrospective studies provide conflicting interpretations of the effect of inherited genetic factors on the prognosis of patients with breast cancer. The primary aim of this study was to determine the effect of a germline BRCA1 or BRCA2 mutation on breast cancer outcomes in patients with young-onset breast cancer. METHODS: We did a prospective cohort study of female patients recruited from 127 hospitals in the UK aged 40 years or younger at first diagnosis (by histological confirmation) of invasive breast cancer...

PURPOSE: Male breast cancer (MBC) is a rare cancer entity, with mutations in BRCA1 and BRCA2 genes accounting for ~ 10% of patients. Multiple-gene sequencing has already entered clinical practice for female breast cancer, whereas the performance of panel testing in MBC has not been studied extensively. Therefore, the aim of this study was to evaluate the clinical utility of panel testing for MBC, by the largest gene panel used so far, through investigation of patients deriving from a population with known founder effects...

Breast cancer risk is a common indication for referral to clinical genetics services. UK National Institute of Health and Care Excellence (NICE) guidelines use family history (FH) to stratify by 10-year risk of breast cancer from age 40. Patients are stratified into population risk (PR, 10-year risk <3%), moderate (MR, 3-8%) and high risk (HR, >8%). Women at increased risk are offered screening at or prior to age 40. To assess the clinical effectiveness of current risk stratification, FH data were obtained for all unaffected women with a FH of breast cancer aged <50, referred to cancer genetics from 2000-2010...

Tobacco smoke is an established carcinogen, but the association between tobacco smoking and cancer risk in BRCA mutation carriers is not clear. The aim of this study was to evaluate prospectively the association between tobacco smoking and cancer incidence in a cohort of BRCA1 and BRCA2 mutation carriers. The study population consisted of unaffected BRCA mutation carriers. Information on lifestyle including smoking histories, reproductive factors, and past medical histories was obtained through questionnaires...

BRCA 1 and 2 genes play a critical role in the safeguarding of DNA integrity. It is now well established that BRCA1 and BRCA2-mutated women are at increased risk of breast and ovarian cancers. However, several lines of evidence indicate that this genetic status may also be associated with ovarian dysfunction, in particular a reduced ovarian reserve. Considering the gonadal toxicity of cancer treatments and the recommendation of prophylactic bilateral salpingo-oophorectomy around 40 years, young BRCA mutation carriers are confronted with difficult family planning decisions...

INTRODUCTION: Breast cancer is the commonest cause of death among middle aged women. BRCA1 associated tumors carry a poor prognosis. Angiogenesis is considered necessary for tumor growth and for its metastasis. Hypoxia stimulates HIF-1α which then activates transcription of various proangiogenic cytokines like VEGF. In the present study we examined HIF-1α expression, sVEGF levels and BRCA1 mutations and their relation with clinicopathological parameters. We also determined whether the angiogenic markers have different role in angiogenesis in BRCA1 related cancers as compared to sporadic breast cancers...

BACKGROUND: The impact of age on breast cancer risk model calculations at the population level has not been well documented. METHODS: Retrospective analysis of formal breast cancer risk assessment in 36 542 females ages 40-84 at a single institution from 02/2007 to 12/2009. Five-year and lifetime breast cancer risks were calculated using Gail, Tyrer-Cuzick version 6 (TC6), Tyrer-Cuzick version 7 (TC7), BRCAPRO, and Claus models. Risk of BRCA mutation was calculated using BRCAPRO, TC6, TC7, and Myriad...

Germline mutations in the BRCA1 and BRCA2 genes are associated with hereditary predisposition to breast and ovarian cancer. Sensitive and accurate detection of BRCA1 and BRCA2 mutations is crucial for personalized clinical management of individuals affected by breast or ovarian cancer, and for the identification of at-risk healthy relatives. We performed molecular analysis of the BRCA1 and BRCA2 genes in 898 Greek families, using Sanger sequencing or Next Generation Sequencing for the detection of small insertion/deletion frameshift, nonsynonymous, truncating and splice-site alterations and MLPA for the detection of large genomic rearrangements...

PurposeTo evaluate the cost-effectiveness of BRCA testing in women with breast cancer, and cascade testing in family members of BRCA mutation carriers.MethodsA cost-effectiveness analysis was conducted using a cohort Markov model from a health-payer perspective. The model estimated the long-term benefits and costs of testing women with breast cancer who had at least a 10% pretest BRCA mutation probability, and the cascade testing of first- and second-degree relatives of women who test positive.ResultsCompared with no testing, BRCA testing of affected women resulted in an incremental cost per quality-adjusted life-year (QALY) gained of AU$18,900 (incremental cost AU$1,880; incremental QALY gain 0...

PURPOSE: The BRCA1 and BRCA2 (BRCA) genes are heavily involved in mammalian cell DNA repair processes. Germline pathogenic mutations in BRCA increase the lifetime risk of developing breast and/or ovarian cancer in women. In the Arabian Peninsula, most breast and ovarian cancers are diagnosed as early-onset cases, some of which may be due to germline variants in BRCA genes. To identify the BRCA germline mutation frequency and spectrum in the Arab breast and ovarian cancers, we have sequenced the protein-coding exons of these genes...

BACKGROUND: Population-based BRCA1/BRCA2 founder-mutation testing has been demonstrated as cost-effective compared to family-history(FH) based testing in Ashkenazi Jewish(AJ) women. However, only one of the three AJ BRCA1/BRCA2 founder-mutations (185delAG(c.68_69delAG), 5382insC(c.5266dupC) and 6174delT(c.5946delT)) is found in the Sephardi Jewish(SJ) population (185delAG(c.68_69delAG)) and the overall prevalence of BRCA mutations in the SJ population is accordingly lower (0.7% compared to 2...

REVIEW
Carla Bartosch, Blaise Clarke, Tjalling Bosse
Recognising hereditary predisposition in a cancer patient has implications both for the patient and the patient's kindred. For the latter, cascade germline testing can reassure those not-at-risk family members while carriers can be enrolled in cancer screening and prevention programs that are medically effective and economically sustainable for health care systems. Furthermore, in many of these syndromes, ramifications of molecular phenotypes are increasing, and it is now emerging that, in addition, they convey prognostic and predictive information...

Women who inherit a mutated copy of the BRCA gene have a higher lifetime risk of developing breast cancer. No large epidemiological studies exist looking at BRCA mutation carriers in UK populations. All patients with BRCA1/BRCA2 mutation identified between 1995 and 2015 were included. Individuals were identified from a prospectively gathered data base. Genetics case-notes were obtained and retrospective analysis performed. 581 female BRCA mutation carriers were identified with a median age of 34 (18-81) at the time of testing...

PURPOSE: Liquid biopsy provides real-time monitoring of tumor evolution and response to therapy through analysis of CTCs and plasma-ctDNA. ESR1 epigenetic silencing potentially affects response to endocrine treatment. We evaluated ESR1 methylation in CTCs and paired plasma-ctDNA. We evaluated ESR1 methylation in CTCs and paired plasma-ctDNA as a potential biomarker for response to everolimus/exemestane treatment. EXPERIMENTAL DESIGN: A highly sensitive and specific real-time MSP assay for ESR1 methylation was developed and validated in: a) 65 primary breast tumors (FFPEs), b) EpCAM+ CTC-fractions (122 patients and 30 healthy donors; HD), c) plasma-ctDNA (108 patients and 30HD), d) in CTCs (CellSearch®) and in paired plasma-ctDNA for 58 BrCa patients...
