Abstract

Background: Emerging evidence suggests that breast microbiota dysbiosis contributes to cancer initiation, progression, prognosis and treatment efficacy. Anyway, available data are referred only to female patients, and studies on males are completely missing. Male breast cancer (MBC) is 70–100 times less frequent, but the mortality rate adjusted to incidence is higher in men than in females. Currently, MBC diagnostic approaches and treatments have generally been extrapolated from the clinical experience gained in women, while few studies focus on characterizing male cancer biology. Taking into account the rising importance of the oncobiome field and the need of MBC targeted studies, we explored the breast cancer oncobiome of male and female patients. Methods: 16S rRNA gene sequencing was performed in 20 tumor and 20 non-pathological adjacent FFPE breast tissues from male and female patients. Results: We documented, for the first time, the presence of a sexually dimorphic breast-associated microbiota, here defined as "breast microgenderome". Moreover, the paired analysis of tumor and non-pathological adjacent tissues suggests the presence of a cancer-associated dysbiosis in male patients, with surrounding tissue conserving a healthier microbiome, whereas in female patients, the entire breast tissue is predisposed to cancer development. Finally, the phylum Tenericutes, especially the genera Mesoplasma and Mycobacterium, could to be involved in breast carcinogenesis, in both sexes, deserving further investigation, not only for its role in cancer development but even as potential prognostic biomarker. Conclusions: Breast microbiota characterization can enhance the understanding of male breast cancer pathogenesis, being useful for detection of new prognostic biomarkers and development of innovative personalized therapies, remarking the relevant gender differences. Plain Language Summary: Breast tissue can become inhabited by microbes through different pathways, and an uneven distribution of these microorganisms could potentially contribute to the development, prognosis, and treatment response of breast cancer. However, the current available data primarily focus on female patients, with a significant dearth of studies on males. To address this gap, the present study investigates the microbiota composition of both tumorous and healthy breast tissue samples from both male and female patients. The findings of this research highlight a disparity in the types of bacteria present in male and female breast tissue. Specifically, it shows that male patients with breast cancer have a higher imbalance of bacteria in the cancerous area compared to the surrounding healthy tissue. In contrast, in females the dysbiosis extend to the whole breast tissue. Moreover, the study identifies specific strains of bacteria that might potentially be involved in the development of breast cancer in both males and females. In conclusion, this study underscores the significance of microbial colonization in breast tissue and its potential influence on breast cancer in both males and females. By expanding our understanding of the microbial composition in breast cancer, we can pave the way for innovative diagnostic methods and treatment approaches for male breast cancer, while simultaneously advancing our knowledge of this complex disease. Highlights: Few studies have been conducted to describe male cancer biology in comparison with female breast cancer. For the first time, we discovered a sexually dimorphic breast-associated microbiome, termed "breast microgenderome". In females, the dysbiosis extend to the whole breast tissue, while in men, it appears to be confined to the tumor site. Tenericutes, particularly the genera Mesoplasma and Mycobacterium, may be implicated in breast carcinogenesis in both sexes. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Previous studies have demonstrated that common breast cancer susceptibility alleles are differentially associated with breast cancer risk for BRCA1 and/or BRCA2 mutation carriers. It is currently unknown how these alleles are associated with different breast cancer subtypes in BRCA1 and BRCA2 mutation carriers defined by estrogen (ER) or progesterone receptor (PR) status of the tumour. less thanbrgreater than less thanbrgreater thanMethods: We used genotype data on up to 11,421 BRCA1 and 7,080 BRCA2 carriers, of whom 4,310 had been affected with breast cancer and had information on either ER or PR status of the tumour, to assess the associations of 12 loci with breast cancer tumour characteristics. Associations were evaluated using a retrospective cohort approach. less thanbrgreater than less thanbrgreater thanResults: The results suggested stronger associations with ER-positive breast cancer than ER-negative for 11 loci in both BRCA1 and BRCA2 carriers. Among BRCA1 carriers, single nucleotide polymorphism (SNP) rs2981582 (FGFR2) exhibited the biggest difference based on ER status (per-allele hazard ratio (HR) for ER-positive = 1.35, 95% CI: 1.17 to 1.56 vs HR = 0.91, 95% CI: 0.85 to 0.98 for ER-negative, P-heterogeneity = 6.5 x 10(-6)). In contrast, SNP rs2046210 at 6q25.1 near ESR1 was primarily associated with ER-negative breast cancer risk for both BRCA1 and BRCA2 carriers. In BRCA2 carriers, SNPs in FGFR2, TOX3, LSP1, SLC4A7/NEK10, 5p12, 2q35, and 1p11.2 were significantly associated with ER-positive but not ER-negative disease. Similar results were observed when differentiating breast cancer cases by PR status. less thanbrgreater than less thanbrgreater thanConclusions: The associations of the 12 SNPs with risk for BRCA1 and BRCA2 carriers differ by ER-positive or ER-negative breast cancer status. The apparent differences in SNP associations between BRCA1 and BRCA2 carriers, and non-carriers, may be explicable by differences in the prevalence of, Funding Agencies|Breast Cancer Research Foundation||MacDonald Family Foundation||Komen Foundation||NIH, NCI|P50 CA 058207|Avon Foundation||UCSF Helen Diller Family Comprehensive Cancer Center UK||CRUK||Russian Federation for Basic Research|10-04-9260110-04-9211011-04-00227|Federal Agency for Science and Innovations|02.740.11.0780|Commission of the European Communities|PITN-GA-2009-238132|Royal Society|JP090615|US National Cancer Institute||Westat, Inc., Rockville, MD||Starr Cancer Consortium||Norman and Carol Stone Genetic Research Fund||Robert and Kate Niehaus Clinical Genetics Initiative at MSKCC||NIH|CA116167CA128978|Research Excellence (SPORE) in Breast Cancer|CA116201|Ministero della Salute|RFPS 2006-5-341353ACC2/R6.9|Kathleen Cuningham Consortium for Research into Familial Breast Cancer (kConFab)||Icelandic Association||Landspitali University Hospital||NEYE Foundation||Deutsches Krebsforschungszentrum (DKFZ)||Associazione Italiana per la Ricerca sul Cancro|4017|Italian citizens||Fondazione Italiana per la Ricerca sul Cancro||Cancer Research UK|C12292/A11174C1287/A10118C1287/A11990C5047/A8385|NIHR||Eileen Stein Jacoby Fund||University of Kansas Cancer Center||Kansas Bioscience Authority Eminent Scholar Program||Familial Cancer Registry (CI)||Tissue Culture Shared Registry at Georgetown University (NIH/NCI)|P30-CA051008|Cancer Genetics Network|HHSN261200744000C|Swing Fore the Cure||German Consortium of Hereditary Breast and Ovarian Cancer (GC-HBOC) GC-HBOC||German Cancer Aid|109076|Centre of Molecular Medicine Cologne (CMMC)||Ligue National Contre le Cancer||Association for International Cancer|AICR-07-0454|Association "Le cancer du sein, parlons-en!"

Abstract

Background: Multiple recent genome-wide association studies (GWAS) have identified a single nucleotide polymorphism (SNP), rs10771399, at 12p11 that is associated with breast cancer risk. Method We performed a fine-scale mapping study of a 700 kb region including 441 genotyped and more than 1300 imputed genetic variants in 48,155 cases and 43,612 controls of European descent, 6269 cases and 6624 controls of East Asian descent and 1116 cases and 932 controls of African descent in the Breast Cancer Association Consortium (BCAC; http://bcac.ccge.medschl.cam.ac.uk/), and in 15,252 BRCA1 mutation carriers in the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA). Stepwise regression analyses were performed to identify independent association signals. Data from the Encyclopedia of DNA Elements project (ENCODE) and the Cancer Genome Atlas (TCGA) were used for functional annotation. Results: Analysis of data from European descendants found evidence for four independent association signals at 12p11, represented by rs7297051 (odds ratio (OR) = 1.09, 95 % confidence interval (CI) = 1.06–1.12; P = 3 × 10-9), rs805510 (OR = 1.08, 95 % CI = 1.04–1.12, P = 2 × 10-5), and rs1871152 (OR = 1.04, 95 % CI = 1.02–1.06; P = 2 × 10-4) identified in the general populations, and rs113824616 (P = 7 × 10-5) identified in the meta-analysis of BCAC ER-negative cases and BRCA1 mutation carriers. SNPs rs7297051, rs805510 and rs113824616 were also associated with breast cancer risk at P < 0.05 in East Asians, but none of the associations were statistically significant in African descendants. Multiple candidate functional variants are located in putative enhancer sequences. Chromatin interaction data suggested that PTHLH was the likely target gene of these enhancers. Of the six variants with the strongest evidence of potential functionality, rs11049453 was statistically significantly associated with the expression of PTHLH and its nearby gene CCDC91 at P < 0.05. Conclusion: This study identified four independent association signals at 12p11 and revealed potentially functional variants, providing additional insights into the underlying biological mechanism(s) for the association observed between variants at 12p11 and breast cancer risk.

Abstract

Introduction: Several common alleles have been shown to be associated with breast and/or ovarian cancer risk for BRCA1 and BRCA2 mutation carriers. Recent genome-wide association studies of breast cancer have identified eight additional breast cancer susceptibility loci: rs1011970 (9p21, CDKN2A/B), rs10995190 (ZNF365), rs704010 (ZMIZ1), rs2380205 (10p15), rs614367 (11q13), rs1292011 (12q24), rs10771399 (12p11 near PTHLH) and rs865686 (9q31.2). Methods: To evaluate whether these single nucleotide polymorphisms (SNPs) are associated with breast cancer risk for BRCA1 and BRCA2 carriers, we genotyped these SNPs in 12,599 BRCA1 and 7,132 BRCA2 mutation carriers and analysed the associations with breast cancer risk within a retrospective likelihood framework. Results: Only SNP rs10771399 near PTHLH was associated with breast cancer risk for BRCA1 mutation carriers \((per-allele hazard ratio (HR) = 0.87, 95% CI: 0.81 to 0.94, P-trend = 3 × 10^{-4})\). The association was restricted to mutations proven or predicted to lead to absence of protein expression \((HR = 0.82, 95% CI: 0.74 to 0.90, P-trend = 3.1 × 10^{-5}, P-difference = 0.03)\). Four SNPs were associated with the risk of breast cancer for BRCA2 mutation carriers: rs10995190, P-trend = 0.015; rs1011970, P-trend = 0.048; rs865686, 2df-P = 0.007; rs1292011 2df-P = 0.03. rs10771399 (PTHLH) was predominantly associated with estrogen receptor (ER)-negative breast cancer for BRCA1 mutation carriers \((HR = 0.81, 95% CI: 0.74 to 0.90, P-trend = 4 × 10^{-5})\) and there was marginal evidence of association with ER-negative breast cancer for BRCA2 mutation carriers (HR = 0.78, 95% CI: 0.62 to 1.00, P-trend = 0.049). Conclusions: The present findings, in combination with previously identified modifiers of risk, will ultimately lead to more accurate risk prediction and an improved understanding of the disease etiology in BRCA1 and BRCA2 mutation carriers.
