Management of early-stage triple-negative breast cancer: recommendations of a panel of experts from the Brazilian Society of Mastology.

BACKGROUND: Triple-negative breast cancer (TNBC) is a heterogenous subtype involving different patterns of behavior and clinical course, demanding a complex, individualized sequence of treatment. The knowledge and attitudes of the affiliated members of the Brazilian Society of Mastology regarding TNBC were evaluated and a consensus regarding management and treatment was reached. METHODS: Affiliates completed a survey involving 44 objective questions. In addition, a specialist meeting was held with 27 experts and 3 ad hoc consultants. The panelists completed the survey before and after brainstorming. Answers achieving 70% of agreement were considered consensual. The chi-square test was used to compare answers between panelists and affiliates and the Kappa coefficient to calculate agreement. RESULTS: Consensus among the panelists increased from 26 (59.1%) to 32 questions (72.7%) following brainstorming (p = 0.17), including 7/10 questions on systemic treatment. Among the affiliates, consensus was achieved for 24 questions (54.5%), resulting in moderate agreement (κ = 0.445). Neoadjuvant chemotherapy should be indicated for almost all cases (except cT1a-b N0) and should include platinum agents. When indicated, immunotherapy is part of the standard of care. The panel reaffirmed the concept of no ink on tumor as indicative of adequate margins and the possibility of sentinel lymph node biopsy for cN1 patients who become cN0 following neoadjuvant therapy. Controversies remain on combining immunotherapy with capecitabine/olaparib in pertinent cases. CONCLUSION: Expert consensus was achieved for > 70% of the questions, with moderate agreement between panelists and affiliates. Educational interventions on systemic breast cancer treatment affected decision-making in 60% of the questions.

Temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service between 2008 and 2017.

BACKGROUND: In Brazil, 70% of the population depends on the public healthcare system. Since early detection is considered crucial, this study aimed to evaluate temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service (SUS) according to the different regions of the country between 2008 and 2017. METHODS: This ecological study analyzed data on breast cancer screening within the SUS for women aged 50-69 years. Coverage was calculated from the ratio between the number of screening tests conducted and the expected number for the target population. Joinpoint regression analysis was used to calculate annual percent changes (APC) in coverage. RESULTS: Around 19 million mammograms were performed in 50-69-year old women within the SUS between 2008 and 2016. The estimated APC indicates that breast cancer screening coverage increased by 14.5% annually in Brazil between 2008 and 2012 (p < 0.01), with figures stabilizing between 2012 and 2017 as shown by an APC of - 0.4% (p = 0.3). In the five geographic regions of the country, the APC initially increased, then stabilized in the north, northeast and southeast and decreased in the south and Midwest. Of the 26 states, coverage increased in seven and remained stable in six. In the other 13, there was an initial increase followed by stabilization in 11, and a reduction in coverage in two. In the Federal District, coverage remained stable throughout the study period. CONCLUSION: Evaluation of the temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service revealed an initial increase, confirming that public policies were effective, although insufficient to ensure organized screening. There appears to be a lack of uniformity between the different regions and states and this situation is highlighted in the final 5-year period, with the APC reflecting stabilization of breast cancer screening coverage.

Mean glandular dose in digital mamography in women with breast implants.

PURPOSE: Mean Glandular Dose (MGD) is the quantity related to the risk of radiation-induced breast cancer. This study aimed to evaluate the MGD in screening mammography for women with breast implants. METHODS: This retrospective study used data of 2680 mammographies of 335 asymptomatic women with mammary implants examined in a digital direct x-ray unit. Each woman had a total of eight images: four in standard views and four with posterior displacement of the implant (ID). Data on kV, mAs, target/filter combination, compressed breast thickness and MGD were obtained from the DICOM header of the stored images. Quantitative variables were presented through descriptive statistics for median (5th-95th percentiles); and the qualitative variables were presented by numbers and percentages. Mean glandular doses of standard views and ID views were compared and statistical analysis was used to assess the influence of implant position, breast glandularity and thickness on mean glandular doses. RESULTS: Median MGD for standard views were 3.30 (2.60-4.00) mGy for CC and 3.31 (2.70-4.20) mGy for MLO. For ID views, median were 1.20 (0.90-2.20) mGy and 1.40 (0.97-3.74) mGy for CC and MLO views, respectively. Median MGD for the whole examination of women with breast implants was 9.60 (7.92-12.07) mGy, ranging from 6.25 to 21.50 mGy. When comparing MGD median for standard and ID views it was found a statistically significant difference (p < 0.05), with higher doses for the standard views due to the greater compressed breast thickness in these views. It was observed that, in the standard views, MGD decreases with increasing breast thickness due to the manual radiographic techniques used to expose the women. It was also observed that implant position does not affect MGD in breast augmentation mammography. CONCLUSION: Mammography of women with mammary implants gives higher radiation doses when compared with those without implants. For more accurate dose assessment in augmented breast mammography, it is necessary that specific conversion factors for the calculation of MGD based on air kerma at entrance of breasts with implants are made available.

Effect of Ki-67 on Immunohistochemical Classification of Luminal A to Luminal B Subtypes of Breast Carcinoma.

It has recently been proposed to include an immunohistochemical marker of cell proliferation, Ki-67, as an element with which to classify the molecular subtypes of breast cancer. The objective of this study was to evaluate the effect of the introduction of the Ki-67 marker on the molecular classification of breast cancer by immunohistochemistry. This study was performed on 234 cases of invasive ductal carcinoma of the breast submitted to two immunohistochemical classification panels, one including Ki-67 and the other not. The data obtained with the two classifications were correlated with well-established prognostic factors such as histologic grade, the number of lymph nodes affected and tumor size. The molecular classification without Ki-67 identified: 136 cases of luminal A (58.1%), 19 cases of luminal B (8.1%), 27 cases of human epidermal growth-factor receptor 2 overexpressing (11.5%), 27 cases of basal-like (11.5%), and 25 cases of nonbasal-like triple-negative tumors (10.7%). When Ki-67 was included, this situation changed significantly, with the following cases being identified: 72 cases of luminal A (30.8%) and 83 cases of luminal B tumors (35.5%), resulting in a Kappa score of 0.216. Evaluation of correlations between the luminal A and luminal B tumor subtypes and the selected prognostic factors showed a statistically significant difference only when Ki-67 was included and only with respect to histologic grade (p < 0.001). The new classification with Ki-67 significantly altered the prevalence of the luminal A and luminal B subtypes and improved correlation with the histologic grade.

Human Papillomavirus vaccination coverage among the female population living in the state of Goiás, Brazil, 2014-2020: a time series study.

OBJECTIVE: To analyze the temporal trend of human papillomavirus (HPV) vaccination coverage among the female population aged 10 to 14 years, living in the state of Goiás, Brazil, between 2014 and 2022. METHODS: This was an ecological time series study using data from the Brazilian National Health System Information Technology Department (Departamento de Informática do Sistema Único de Saúde - DATASUS); the annual vaccination coverage rate was calculated based on the number of second doses administered; the trend of the rates was analyzed using the Prais-Winsten model. RESULTS: A total of 407,217 second doses of the quadrivalent HPV vaccine were administered to the female population aged 10-14 years, with annual vaccination coverage rates ranging from 12.3% (2019) to 30.0% (2015), and an annual percentage change (APC) of 0.7% (95%CI 0.9; 0.2; p-value = 0.030). CONCLUSION: In Góias state, the quadrivalent HPV vaccine coverage rate was below the national target (80%), showing a stationary trend in the time series.

Impact of the genomic signature of 70-genes for breast cancer in the public system and in supplementary health care in a country of medium socioeconomic development.

INTRODUCTION: The financial impact of breast cancer has been discussed due to its high incidence and the increased costs of systemic therapy and is even more relevant in countries with low and medium socioeconomic development. OBJECTIVE: To evaluate the financial viability of using the MammaPrint™ (MP) genetic signature in a public and private system in a country with a medium socioeconomic development index. MATERIAL AND METHOD: A pharmacoeconomic trial with a cost-benefit analysis evaluating the reduction in costs of chemotherapy, support drugs, and materials used during chemotherapy infusion in high-risk hormone receptor-positive (HR+) breast cancer patients submitted to analysis using the MammaPrint™ genetic signature. RESULTS: The value of using MammaPrint™ in the Unified Health System (SUS) would bring an additional cost of US$ 1,334.56 per patient in the over-50 age group. In private medicine, the use of MammaPrint™ in the same population would result in cost savings ranging from US$ 2,422.53 to US$ 9,989.95 per patient. CONCLUSION: The use of MP in RH + breast cancer patients with high clinical risk and low genomic risk in Brazil leads to significant savings in resources when applied to supplementary healthcare. In the SUS, reducing the costs of MP for large-scale use could make its application viable. These values need to be re-evaluated in each institution, using the methodology applied in the trial, adjusting according to costs, to obtain a result that reflects its reality.

Testosterone Deficiency in Hypertensive Men: Prevalence and Associated Factors. / Deficiência de Testosterona em Homens Hipertensos: Prevalência e Fatores Associados.

BACKGROUND: Testosterone deficiency (TD) is a prevalent condition in our midst and still very neglected. Arterial hypertension (AH) is one of the possible associated factors. OBJECTIVES: To determine the prevalence of TD in a hypertensive male population and the factors associated with its occurrence, such as age, time since hypertension diagnosis, number of antihypertensive classes, body mass index (BMI), diabetes, dyslipidemia, chronic kidney disease (CKD), positive symptoms of TD (positive ADAM questionnaire) and use of spironolactone. METHODS: Cross-sectional study with administration of the ADAM questionnaire, assessment of biochemical, clinical, and anthropometric data. Patients were stratified into DT and normal testosterone groups. Categorical variables were compared using the chi-squared test and continuous variables using the Mann-Witney test; variables with significance (p<0,05) were analyzed by multivariable linear regression. RESULTS: The prevalence of TD was 26.36%. There was an association between TD and body mass index (BMI) (p=0.0007) but there was no association with age (p=0.0520), time of hypertension diagnosis (p=0.1418), number of classes of antihypertensive drugs (p=0.732), diabetes (p=0.1112); dyslipidemia (p=0.3888); CKD (p=0.3321); use of spironolactone (p=0.3546) or positive ADAM questionnaire (p=0.2483). CONCLUSIONS: TD was highly prevalent and positively associated with BMI. Total testosterone (TT) declined by 8.44ng/dL with a one unit increase in BMI and dropped by 3.79ng/dL with a one-year increase in age.

FUNDAMENTO: A deficiência de testosterona (DT) é uma condição prevalente em nosso meio e ainda muito negligenciada. A hipertensão arterial (HA) é um de seus possíveis fatores associados. OBJETIVOS: Determinar a prevalência de DT em uma população masculina hipertensa e os fatores associados à sua ocorrência, como idade, tempo de diagnóstico de HA, número de classes de anti-hipertensivos, índice de massa corporal (IMC), diabetes, dislipidemia, doença renal crônica (DRC), sintomas positivos de DT (questionário ADAM positivo) e uso de espironolactona. MÉTODOS: Estudo transversal com aplicação do questionário ADAM, e avaliação de dados bioquímicos, clínicos e antropométricos. Os pacientes foram estratificados em grupos de DT e testosterona normal. As variáveis categóricas foram comparadas pelo teste do qui-quadrado e as variáveis contínuas pelo teste de Mann-Witney; as variáveis com significância (p<0,05) foram submetidas à regressão linear multivariada. RESULTADOS: A prevalência de DT foi de 26,8%. Houve associação entre DT e IMC (p=0,0007), mas não houve com idade (p=0,0520), tempo de diagnóstico de HA (p=0,1418), número de classes de anti-hipertensivos (p=0,0732), diabetes (p=0,1112); dislipidemia (p=0,3888); presença de DRC (p=0,3321); uso de espironolactona (p=0,3546) e questionário ADAM positivo (p=0,2483). CONCLUSÕES: A prevalência de DT foi alta e houve associação positiva com IMC. A testosterona total (TT) declinou 8,44 ng/dL com o aumento de 1 kg/m2 no IMC e caiu 3,79 ng/dL com o avanço em um ano na idade.

Breast cancer screening and diagnosis in older adults women in Brazil: why it is time to reconsider the recommendations.

Introduction: Breast cancer screening in women of 70 years of age or older remains controversial due to a lack of studies that include women of this age. Methods: This ecological study evaluated data from the Brazilian National Health Service (SUS) on breast cancer screening and staging in this age group compared to 50-69-year olds, for Brazil as a whole and for its geographical regions, between 2013 and 2019. A secondary database was obtained from the outpatient data system of the SUS's Informatics Department, the Brazil Oncology Panel, the Brazilian Institute of Geography and Statistics, the Supplementary Health Agency and the Online Mortality Atlas. Results: There was a marked reduction in screening in women ≥70 years of age (annual percent change [APC] -3.5; p < 0.001) compared to those of 50-69 years of age (APC-2.2; p = 0.010). There was a trend towards an increase in clinical staging, with a greater occurrence of stages III and IV in the ≥70 group (44.3%) compared to the women of 50-69 years of age (40.8%; p < 0.001). Conclusion: Considering the increasing age of the Brazilian population and the heterogeneity among older adults women, screening for the over-70s within the SUS merits greater debate insofar as the implementation of public policies is concerned.

Are All Views with and without Displacement Maneuver Necessary in Augmentation Mammography? Putting Numbers Into Perspective.

OBJECTIVE: Augmentation implants pose a challenge for radiologists. Displacing the implant allows slightly more breast tissue to be visualized than the standard compression views. The objective of this study was to verify the agreement between craniocaudal (CC) views and CC with implant displacement (CC-ID), mediolateral oblique (MLO) and MLO-ID and the inter- and intraobserver agreement of mammographic images for finding abnormal images. METHODS: The main outcomes [BI-RADS® normal=1,2; abnormal=3,4,5)] were analysed by 3 readers (reader1; reader 2, 1st round, reader 2, 2nd round) in 360 women with breast implants. Comparison between CC/CC-ID and MLO/MLO-ID, and degree of agreement for mammographic images between researchers were made using Kappa index. Proportions were calculated using a 95% confidence interval (95%CI). RESULTS: A total of 87 abnormal findings were identified by reader 2, 2nd round. Abnormal findings were observed in CC-ID=18.8% (68 out of 360; 95%CI=15.1%-23.2%) compared to CC=10.8% (39 out of 360; 95%CI=8%-14.4%, k=0.49); in MLO=10.5% (38 out of 360; 95%CI=7.7%-14.1%) compared to MLO-ID=15.8% (57 out of 360; 95%CI=12.4%-19.9%, k=0.55). The CC-ID was the view that singly identified more abnormal findings (20 out of 87; 23%; 95%CI=15.4% to 32.8%) and the CC was the view that least detected abnormal findings (1 out 87; 95%CI=0.2% to 6.2%). The inter- and intraobserver agreement between readers views was 0.67 and 0.74 respectively. CONCLUSIONS: In women with breast augmentation implants, all views are necessary to identify breast tissue abnormalities. In our sample, the inter- and intraobserver agreement were "substantial".

Publication rate of scientific papers presented at the largest event on breast cancer research in Latin America.

PURPOSE: Medical congresses allow scientific production to be appropriately disseminated and discussed. However, most of the scientific papers presented at medical congresses do not go on to be published in indexed journals. The present study aimed to determine the publication rate of papers presented at the Brazilian Breast Cancer Symposium (BBCS) and trends associated with publication over that timeframe. METHODS: This was a retrospective, observational study evaluating scientific papers presented at the BBCS between 2012 and 2017. All the abstracts presented at the event within this timeframe were recorded. Next, a search for papers was made using online databases (BIREME/LILACS and MEDLINE/PubMed) and in the curricula of the authors on the Lattes Platform. RESULTS: Overall, 543 abstracts of papers presented at the BBCS between 2012 and 2017 were included. Of these, 112 (20.6%) had been published in an indexed journal, mostly in English (67.0%), in journals with an impact factor of 2.0-3.0 (21.4%) and ≥1 year after presentation at the event (75.9%). The factors associated with publication were: study conducted in a public institution (p = 0.01), oral or commented poster presentation (p > 0.001) and study concerning rehabilitation following breast cancer (p = 0.04). There was a downward trend in the rate of publication of articles over the years (p = 0.01). Conversely, the impact factor of the publications increased significantly between 2012 and 2017 (p = 0.04). CONCLUSION: The publication rate of papers presented at the BBCS is low and remains consistent over the study period despite academic incentives and substantial awards.

Prognostic Role of PD-L1 Expression in Invasive Breast Cancer: A Systematic Review and Meta-Analysis.

Programmed death ligand 1 (PD-L1) has been investigated in various types of cancer; however, the role of PD-L1 expression in breast cancer remains controversial. We performed a systematic review and meta-analysis to assess the association of PD-L1 expression with clinicopathological variables, overall survival (OS), and disease-free survival (DFS) in invasive breast cancer. A total of 965 articles were included from CINAHL, Embase, PubMed, and Scopus databases. Of these, 22 studies encompassing 6468 cases of invasive breast cancer were included in the systematic review, and 15 articles were included in the meta-analysis. PD-L1 expression was associated with age ≥ 50 years, lymph node status-negative, progesterone receptor-negative, Ki67 ≥ 20%, and human epidermal growth factor receptor 2 (HER2)-negative. PD-L1 positivity was associated with worse OS (hazard ratio, HR, 2.39; 95% confidence interval, CI, 1.26-3.52; p =< 0.000); however, there was no significant improvement in DFS (HR 0.17; 95% CI -0.12-0.46; p =< 0.252). PD-L1 positivity was significantly associated with the clinicopathological characteristics of favorable and unfavorable prognoses. However, the final clinical outcome was associated with lower OS and had no significant association with DFS.

Chemotherapy negatively impacts body composition, physical function and metabolic profile in patients with breast cancer.

BACKGROUND: Evidence suggests that chemotherapy (CT) leads to unfavorable outcomes on nutritional and metabolic profile; however, this is poorly understood. OBJECTIVE: To evaluate the impact of CT on body composition, bone mineral density (BMD), insulin resistance, lipid markers related to atherosclerotic cardiovascular diseases in women recently diagnosed with breast cancer according to menopausal status. METHODS: This is a prospective study that enrolled women newly diagnosed with stage II-III breast cancer (2014-18). Body composition were measured by dual-energy x-ray absorptiometry. Blood samples were collected to assess lipid profile, insulin resistance and sensitivity, visceral adiposity index and lipid accumulation product were calculated. Dietary intake, physical activity and function were also evaluated at the time of breast cancer diagnosis and after CT completion. RESULTS: Ninety-nine women (40.4% in the premenopausal stage) aged 51 ± 1 years took part in this study. CT duration was 197 ± 27 days and main regimen was anthracyclines with taxanes (88.9%). CT was associated with an increase in total and central adiposity, insulin resistance, and all lipid-related markers, and a decrease in appendicular lean mass index, BMD and HDL-c concentration. Premenopausal women experienced greater unfavorable outcomes on adiposity markers and BMD compared to postmenopausal women (p < 0.01). No changes were observed in dietary intake and physical activity after CT. CONCLUSIONS: Breast cancer CT negatively impacted body composition and metabolic profile. Premenopausal women experienced greater unfavorable impact on adiposity markers and BMD.

Evaluation of ionizing radiation as a risk factor for the incidence of breast cancer: long-term analysis after the cesium-137 accident in Goiânia, Brazil. An ecological study.

BACKGROUND: The largest radiological accident to occur in any urban area happened in Goiânia, Brazil, in 1987. OBJECTIVE: To evaluate the association between breast cancer incidence and ionizing radiation levels. DESIGN AND SETTING: Ecological study among residents of the city of Goiânia, Brazil. METHODS: The central region of Goiânia, with seven major sources of contamination from cesium-137, was defined as the study area. The addresses of women diagnosed with breast cancer were identified between 2001 and 2010. The data were geographically referenced and, using census data, the annual averages of crude incidence rates were estimated. The existence of clusters of new cases was ascertained by means of the Moran index. Correlations of radiometric measurements with the incidence were assessed using unconditional linear regression. RESULTS: A total of 4,105 new cases were identified, of which 2,233 were in the study area, and of these, 1,286 (57.59%) were georeferenced. The gross rates of total and referenced cases were 102.91 and 71.86/100,000 women, respectively. These were close to the average for Brazilian state capitals, which is 79.37/100,000 women. The cluster analysis showed slight correlations in three small sets of census tracts, but these were far from the sources of contamination. The scatter plot of points and the R2 value close to zero indicated that there was no association between the variables. CONCLUSION: This study reinforces the hypothesis that the ionizing radiation levels to which women living in Goiânia are now exposed to are not associated with the onset of new cases of breast cancer.

Conclusão: Em Goiás, a taxa de cobertura da vacina quadrivalente contra HPV esteve aquém da meta nacional (80%), com tendência estacionária da série temporal.

Surgical breast incisions treated with 2-octyl-cyanoacrylate versus intradermal nylon suture: a randomized clinical trial. / Incisões cirúrgicas mamárias tratadas com 2-octilcianoacrilato versus sutura intradérmica com fio de nylon: ensaio clínico randomizado.

OBJECTIVE: to evaluate the safety profile and aesthetic results of 2-octyl-cyanoacrylate versus intradermal nylon suture in breast surgeries. METHODS: an open-label, randomized, clinical trial evaluating the occurrence of complications, such as dehiscence, hematoma, infection, and allergic reactions after the use of 2-octyl-cyanoacrylate or nylon thread. The size of the incisions, skin closure time, and total surgical time were also analyzed. The aesthetic outcome was evaluated at 40 and 180 days after surgery, by means of the average width of the surgical wound and by subjective conceptual assessment (optimal, good, reasonable, or poor). RESULTS: 79 patients were included: 37 in the 2-octyl-cyanoacrylate group and 42 in the nylon suture group. The study was stopped before the end of patient recruitment due to the occurrence of a greater number of dehiscences in the adhesive group (OR: 11.42; 95%CI: 1.36-96.02; p=0.007). Regarding the other analyzed complications, the surgical duration and postoperative aesthetic result, no significant differences were observed between the groups. The mean operative wound size was greater in the adhesive group than in the suture group, but there was no correlation between wound size and the largest number of dehiscences. CONCLUSION: while the cosmetic outcomes with the two techniques were similar, there was a greater risk of dehiscence with the use of 2-octyl-cyanoacrylate compared to intradermal suturing.

OBJETIVO: avaliar o perfil de segurança e os resultados estéticos do 2-octilcianoacrilato versus sutura intradérmica com fio de nylon em cirurgias mamárias. MÉTODOS: ensaio clínico randomizado, aberto, que avaliou a ocorrência de complicações, como deiscência, hematoma, infecção e reações alérgicas após o uso do 2-octilcianoacrilato ou do fio de nylon. Também foi analisado o tamanho das incisões, o tempo de fechamento da pele e o tempo cirúrgico total. O resultado estético foi avaliado após 40 e 180 dias da cirurgia, por meio da largura média da ferida operatória e por avaliação subjetiva conceitual (ótimo, bom, razoável ou ruim). RESULTADOS: foram incluídas 79 pacientes, sendo 37 no grupo 2-octilcianoacrilato e 42 no grupo de sutura com fio de nylon. O estudo foi interrompido antes do término do recrutamento dos pacientes pela ocorrência de maior número de deiscências no grupo do adesivo (OR: 11,42; IC95%: 1,36-96,02; p=0,007). Em relação às demais complicações analisadas, ao tempo cirúrgico e ao resultado estético no pós-operatório, não se observaram diferenças significativas entre os grupos. A média do tamanho da ferida operatória foi maior no grupo do adesivo em relação ao grupo da sutura, mas não houve correlação entre o tamanho da ferida e o maior número de deiscências. CONCLUSÃO: o 2-octilcianoacrilato apresentou maior risco de deiscência em relação à sutura intradérmica, com resultados estéticos equivalentes.

Sedentary Behavior and Alcohol Consumption Increase Breast Cancer Risk Regardless of Menopausal Status: A Case-Control Study.

Identification of modifiable risk factors for breast cancer is critical for primary prevention of the disease. The aim of this study was to evaluate how certain lifestyle variables modify the chances of developing breast cancer based on menopausal status. A case-control study was performed in a group of 542 women, 197 who were diagnosed with breast cancer and 344 control individuals. The groups were matched by age, body mass index, and menopausal status. Participants were evaluated for level of physical activity, alcohol consumption, smoking habit, weight, height, and waist circumference (WC). A multivariate logistic regression model was used to estimate odds ratios and 95% confidence intervals (95% CI). Regular consumption of alcoholic beverages (2.91, 95% CI 1.58-5.38 and 1.86, 95% CI 1.15-3.03) and sedentary behavior (2.08; 95% CI 1.12-3.85 and 1.81; 95% CI 1.12-2.94) were associated with breast cancer risk in pre- and postmenopausal women, respectively. High WC (3.31, 95% CI 1.45-7.55) was associated with an increased risk of developing breast cancer in premenopausal women. While in postmenopausal women, current smoking (2.43, 95% CI 1.01-5.83) or previous history of smoking (1.90; 95% CI 1.14-3.14) increased the chances of developing breast cancer. Sedentary behavior and current consumption of alcoholic beverages were more likely to increase the risk of developing breast cancer regardless of menopausal status.
