Although somatic mutations in core spliceosome components and their associated factors have been described in some cases, almost nothing is known about the contribution of distorted epigenetic patterns to aberrant splicing. Herein, we show that the splicing RNA-binding protein CELF2 is targeted by promoter hypermethylation-associated transcriptional silencing in human cancer. Focusing on the context of breast cancer, we also demonstrate that CELF2 restoration has growth-inhibitory effects and that its epigenetic loss induces an aberrant downstream pattern of alternative splicing, affecting key genes in breast cancer biology such as the autophagy factor ULK1 and the apoptotic protein CARD10. Furthermore, the presence of CELF2 hypermethylation in the clinical setting is associated with shorter overall survival of the breast cancer patients carrying this epigenetic lesion. ; Health Department PERIS-project of the Catalan Government (Generalitat de Catalunya) AGAUR of the Catalan Government (Generalitat de Catalunya) Instituto de Salud Carlos III Ministerio de Economia y Competitividad (MINECO) European Union (EU) Foundation CELLEX La Caixa Foundation

Breast neoplasms are the most common malignant tumors among women. In recent years breast cancer incidence rate has increased. Due to this fact the European Union presents evidence-based guidelines on breast cancer screening and diagnosis. Recommended and commonly used screening test is mammography. The effectiveness of prophylaxis is measured by a decrease in breast cancer mortality rate. Detailed recommendations in EU member countries differ from those presented by the EU institutions. This paper compares the screening programme in Poland to screening programmes in other EU members. The evaluation considers compliance with European screening guidelines and changes in mortality rates since the introduction of the screening programs. General guidelines in Poland are close to European ones. However, some Polish health centers still use analog mammography instead of recommended digital mammography. Furthermore, mortality rate changes in Poland maintain on a constant level due to women's reluctant participation in screening tests.

AIMS: The aim of this study was to evaluate the association of diabetes and diabetes treatment with risk of postmenopausal breast cancer. METHODS: Histologically confirmed incident cases of postmenopausal breast (N = 916) cancer were recruited from 23 Spanish public hospitals. Population-based controls (N = 1094) were randomly selected from primary care center lists within the catchment areas of the participant hospitals. ORs (95 % CI) were estimated using mixed-effects logistic regression models, using the recruitment center as a random effect term. Breast tumors were classified into hormone receptor positive (ER+ or PR+), HER2+ and triple negative (TN). RESULTS: Diabetes was not associated with the overall risk of breast cancer (OR 1.09; 95 % CI 0.82-1.45), and it was only linked to the risk of developing TN tumors: Among 91 women with TN tumors, 18.7 % were diabetic, while the corresponding figure among controls was 9.9 % (OR 2.25; 95 % CI 1.22-4.15). Regarding treatment, results showed that insulin use was more prevalent among diabetic cases (2.5 %) as compared to diabetic controls (0.7 %); OR 2.98; 95 % CI 1.26-7.01. They also showed that, among diabetics, the risk of developing HR+/HER2- tumors decreased with longer metformin use (ORper year 0.89; 95 % CI 0.81-0.99; based on 24 cases and 43 controls). CONCLUSION: This study reinforces the need to correctly classify breast cancers when studying their association with diabetes. Given the low survival rates in women diagnosed with TN breast tumors and the potential impact of diabetes control on breast cancer prevention, more studies are needed to better characterize this association. ; This work was supported by research Grants from Spain´s Health Research Fund Fondo de Investigación Sanitaria (PI12/00488, PI08/1770, PI08/0533, PI08/1359, PS09/00773, PS09/01286, PS09/01903, PS09/02078, PS09/01662, PI11/01403, PI11/01889, PI11/00226, PI11/01810, PI11/02213, PI12/00265, PI12/01270, PI12/00715, PI12/00150), Fundación Marqués de Valdecilla (API 10/09), ICGC International Cancer Genome Consortium CLL, Junta de Castilla y León (LE22A10-2), Consejería de Salud of the Junta de Andalucía (PI-0571), Conselleria de Sanitat of the Generalitat Valenciana (AP_061/10), Recercaixa (2010ACUP 00310), Regional Government of the Basque Country by European Commission GrantsFOOD-CT-2006-036224-HIWATE, Spanish Association Against Cancer (AECC) Scientific Foundation and the Catalan Government DURSI Grant 2014SGR647 ; Sí

These regions were explored by combining association analysis with in silico genomic feature annotations. We defined 205 independent risk-associated signals with the set of credible causal variants in each one. In parallel, we used a Bayesian approach (PAINTOR) that combines genetic association, linkage disequilibrium and enriched genomic features to determine variants with high posterior probabilities of being causal. Potentially causal variants were significantly over-represented in active gene regulatory regions and transcription factor binding sites. We applied our INQUSIT pipeline for prioritizing genes as targets of those potentially causal variants, using gene expression (expression quantitative trait loci), chromatin interaction and functional annotations. Known cancer drivers, transcription factors and genes in the developmental, apoptosis, immune system and DNA integrity checkpoint gene ontology pathways were over-represented among the highest-confidence target genes. ; European Union's Horizon 2020 Research and Innovation Programme under Marie Sklodowska-Curie grant PERSPECTIVE project (Government of Canada through Genome Canada) Canadian Institutes of Health Research (CIHR) PERSPECTIVE project ('Ministere de l'Economie de la Science et de l'Innovation du Quebec' (Genome Quebec) PERSPECTIVE project (Quebec Breast Cancer Foundation) NCI Genetic Associations and Mechanisms in Oncology (GAME-ON) initiative United States Department of Health & Human Services National Institutes of Health (NIH) - USA Cancer Research UK European Community (EC) European Union (EU) Canadian Institutes of Health Research (CIHR) Ministry of Economic Development, Innovation and Export Trade of Quebec United States Department of Health & Human Services National Institutes of ...

An inverse association of breast cancer was observed among women who lived through the puberty period in coastal villages, compared with women residing in the capital area [HR, 0.78; 95% confidence interval (CI), 0.61-0.99]. In the subgroup analysis of this Icelandic population, generally characterized by high fish intake, we found an indication of lower risk of breast cancer among women with high fish consumption (more than 4 portions per week) in adolescence (HR, 0.71; 95% CI, 0.44-1.13) and midlife (HR, 0.46; 95% CI, 0.22-0.97), compared with low consumers (2 portions per week or less). No association was found for fish liver oil consumption in any time period, which could be due to lack of a reference group with low omega-3 fatty acids intake in the study group.Conclusions: Our findings suggest that very high fish consumption in early to midlife may be associated with a reduced risk of breast cancer.Impact: Very high fish consumption in early adulthood to midlife may be associated with decreased risk of breast cancer.

The book summarizes the high risk breast imaging options, including newest techniques and schedules. Pathologic evaluation of high risk lesions are featured as well as the management issues surrounding these lesions. The volume also covers the management of concomitant cancer risk and screening strategies.

ABSTRACT Objective: to assess the implementation of actions for early detection of breast cancer in Primary Care and to verify the adequacy of these actions with the Ministry of Health recommendations. Method: a cross-sectional study conducted from September 2017 to March 2018 with 736 women registered in Basic Health Units in two municipalities in Acre. For data collection, a validated questionnaire was used. In statistical analysis, the chi-square test or Fisher's exact test was applied. Results: the frequency of mammography was 42%. Of the women at standard risk for breast cancer, only 5,8% underwent mammography properly. Conclusion: there was a low compliance of early detection actions to the Ministry of Health recommendations; thus, the need to adopt measures to increase professionals' adherence to government proposals is highlighted, as well as continuous actions assessments.
