Relationship between breast arterial calcification and coronary artery disease by invasive coronary angiography in postmenopausal women.

PURPOSE: To evaluate the relationship between the presence of BAC and coronary artery disease (CAD) by invasive coronary angiography (ICA) in postmenopausal women. METHODS: In this cross-sectional study, postmenopausal women (age ≥ 45 years) with history of CAD, who underwent both ICA and digitized mammography, within six months of each other, were enrolled. Women who underwent prior percutaneous coronary intervention, or exhibited grade D breast density (BI-RADS®) or breast cancer upon mammography were excluded. Digital mammograms were identified in the electronic medical record system and reviewed for the presence of BAC, without knowledge of the ICA results by two experienced physicians. The ICA results were obtained from the electronic medical record, and categorized as follows: 1-single-vessel disease; 2-two-vessel disease; and 3-multivessel disease (≥3vessels). For statistical analysis Student t test, Gamma distribution, Chi-square test and logistic regression (odds ratio,OR) were used. RESULTS: Of the 183 postmenopausal women evaluated, 39 (21.3 %) had BAC. Women with BAC were older and had a longer time since menopause when compared to women without BAC (68.2 ± 9.6 × 59.6 ± 10.0 years of age and 19 ± 10.1 × 13.5 ± 8.2 years, respectively) (p < 0.0.0001). Among the clinical and cardiovascular characteristics evaluated, only the incidence of smoking was higher in women with BAC (p = 0.007). There was no difference in the number of affected vessels upon ICA in women with or without BAC (p = 0.683). In multivariate analysis, after adjustment for age, time since menopause and smoking, the presence of BAC was not associated with a significant risk of observing a greater number of affected vessels upon ICA (OR1.07; 95 %CI 0.41-2.76, p = 0.609). CONCLUSIONS: The presence of BAC was not associated with the severity of CAD in postmenopausal women.

Association Between Metabolic Syndrome and Immunohistochemical Profile at Breast Cancer Diagnosis in Postmenopausal Women.

BACKGROUND: The aim of this study was to evaluate the association between metabolic syndrome (MetS) and the immunohistochemical profile of breast cancer (BC) in postmenopausal women. METHODS: This cross-sectional cohort study included 189 women, aged 45 to 75years and amenorrhea >12 months, with newly diagnosed BC and no previous cancer treatment. Clinical, anthropometric and biochemical data were collected, as well as data on BC hormone status (estrogen receptor, ER; progesterone receptor, PR; human epidermal growth factor receptor-2, HER-2), and epithelial proliferative activity (Ki-67). Tumors were divided into 5 subtypes:luminal A, luminal B HER-2 negative, luminal B HER-2 positive, non-luminal HER-2, and triple negative. Women with three or more of the following criteria were diagnosed with MetS: waist circumference ≥88cm; triglycerides ≥150mg/dL; HDL-cholesterol <50mg/dL; blood pressure ≥130/85mmHg; glucose ≥100mg/dL. RESULTS: Sixty-three (33.3%) of the 189 patients had MetS at the time of diagnosis. Women with MetS had a higher frequency of tumors ≤ 2cm than women without MetS (49.2% vs. 31.8%) (P = .038). There were no differences in histological grade, staging, or axillary lymph node metastasis (P > .05). The proportion of PR-positive (P = .006), HER-2-negative (P = .034), and luminal B HER-2-negative (P = .038) tumors was higher among patients with MetS compared to women without MetS (79.4% vs. 61.8%, 89.9% vs. 78.6% and 44.5% vs. 27.8%, respectively). Multivariate analysis adjusted for age, time since menopause and BMI showed a higher risk for luminal B HER-2-negative tumors among women with MetS (OR 2.00, 95% CI 1.03-3.89), obese patients (OR 2.03, 95% CI 1.06-3.90), and women with abdominal obesity (OR 1.96, 95% CI 1.01-4.03). CONCLUSION: In postmenopausal women with newly diagnosed BC, the presence of MetS was associated with smaller tumor size, PR-positive and HER-2-negative status, and the luminal B tumor subtype.

Evaluation of metabolic syndrome and obesity in breast cancer survivors undergoing interdisciplinary approach: a prospective cohort study

Objective: The purpose of this study was to evaluate the occurrence of the metabolic syndrome and obesity during the first year after the diagnosis of breast cancer in women undergoing interdisciplinary approach. Methods: In this prospective study, 81 women (age ≥45 years) with recent histological diagnosis of breast cancer, no established cardiovascular disease, who attended at a single specialized center with an interdisciplinary approach (medical, nutritionist, and psychological) were included. Results: Women with metabolic syndrome were considered to have three or more diagnostic criteria: waist circumference >88 cm, triglycerides ≥150 mg/dL, high-density lipoprotein <50 mg/dL, blood pressure ≥130/85 mmHg, and glucose ≥100 mg/dL. Obesity was considered when body mass index >30 kg/m2 and abdominal obesity with waist circumference >88 cm. The evaluations were carried out at three time points: first cancer visit (T0m), 6 months (T6m), and 12 months (T12m). For statistical analysis, the McNemar test was used to compare these time points and the chi-square test was used for trends. The mean age of the patients was 58.4±10.7 years, and 83.3% of them were in the postmenopausal stage. There were no differences in the metabolic syndrome, body mass index, and waist circumference assessments at the indicated time points. When comparing the individual quantitative criteria for metabolic syndrome, there was a statistically significant difference in the values of triglycerides and blood glucose. At times T0m, T6m, and T12m, an increase in the mean triglyceride values was observed, 121, 139.4, and 148.46 mg/dL (p=0.003) and a reduction in the mean glucose values, 106.6, 100.46, and 98.96 mg/dL (p=0.004), respectively. Conclusion: Women with breast cancer subjected to interdisciplinary evaluation did not show an increase in the occurrence of metabolic syndrome and obesity during the first year following their cancer diagnosis.

Evaluation of sexual dysfunction in Brazilian women with breast cancer: partial results

Objective: To assess the pattern of sexual performance in women treated for breast cancer. Methods: This is a cross-sectional study on women treated for breast cancer. Inclusion criteria: to have undergone the first-line therapy for cancer and the cancer not being classified as stage IV. Data on cancer were collected by the analysis of medical records. For the evaluation of sexual performance, women were submitted to individual interviews, with the application of the Quociente Sexual ­ Versão Feminina (QS­F) questionnaire. Sexual performance was classified as: bad, unfavorable, regular, good, and excellent. The diagnosis of sexual dysfunction was established to women with score ≤ 60. For descriptive analyses, absolute (n) and relative (%) frequencies were performed, and for the comparison between the quantitative variables the Student's t-test was used. Results: 31 women with a mean age of 55.2 years were included, 35% were classified as clinical stage II, 84% underwent conservative surgery, 65% underwent chemotherapy, and 80% used endocrinotherapy. Regarding sexual performance, 62% spontaneously think about sex, 35% are always interested in sex, and 51.7% have some degree of pain during intercourse. After calculating the score, it was concluded that 6.5% had bad sexual performance; 19.4%, unfavorable; 19.4%, regular; 41.9%, good; and 12.8%, excellent. The mean score was 58.7 points (standard deviation = 21.4, median of 64, minimum of 16, and maximum of 90 points), and 45.2% of women were diagnosed with sexual dysfunction. The provided treatments and the length of follow-up did not have a significant correlation with sexual performance. Conclusion: Most women treated for breast cancer had sexual performance classified as "good and excellent," although a significant percentage had a diagnosis of sexual dysfunction.

High risk for cardiovascular disease in postmenopausal breast cancer survivors.

OBJECTIVE: Breast cancer patients have a higher mortality risk of cardiovascular disease (CVD) than women from the general population. CVD risk may increase significantly in postmenopausal women with early-stage breast cancer. The aim of this study was to evaluate risk factors for CVD in postmenopausal breast cancer survivors. METHODS: In this cross-sectional study, 96 postmenopausal breast cancer survivors were compared with 192 postmenopausal women. The main group included women with amenorrhea >12 months, aged ≥45 years, with breast cancer, and without established CVD. The control group fulfilled the same criteria, but did not have breast cancer. Groups were matched by age, time since menopause, and body mass index, in a ratio of 1 case to 2 controls (1:2). Women with three or more of the following criteria were diagnosed with metabolic syndrome: waist circumference >88 cm; triglycerides ≥150 mg/dL; high-density lipoprotein cholesterol <50 mg/dL; blood pressure ≥130/85 mm Hg; and glucose ≥100 mg/dL. Immunoassays were used (enzyme-linked immunosorbent assay test) for measurement of plasma heat shock proteins (HSP) 60 and 70 concentrations. Atherosclerotic disease was determined by intima-media thickness (>1 mm) of the carotid arteries and/or the presence of atheromatous plaque assessed by carotid artery ultrasound (scanner duplex). RESULTS: Breast cancer patients had higher HSP60 levels and lower HSP70 levels than controls (P < 0.05). Analysis showed that the odds of developing metabolic syndrome (odds ratio [OR] = 4.21, 95% CI, 2.28-7.76), atheromatous plaque (OR = 2.61, 95% CI, 1.19-5.72), diabetes (OR = 4.42; 95% CI, 1.86-10.49), hypertriglyceridemia (OR = 2.32, 95% CI, 1.33-4.0), and increased waist circumference (OR = 11.22, 95% CI, 4.0-31.65) was significantly higher in women treated for cancer than in women without breast cancer. CONCLUSIONS: Postmenopausal breast cancer survivors had a stronger association with risk factors for cardiovascular disease than postmenopausal women without breast cancer.

Risk of metabolic syndrome in postmenopausal breast cancer survivors.

OBJECTIVE: The aim of this study was to assess the risk of metabolic syndrome (MetS) in postmenopausal breast cancer survivors as compared with postmenopausal women without breast cancer. METHODS: In this cross-sectional study, 104 postmenopausal breast cancer survivors were compared with 208 postmenopausal women (controls) attending a university hospital. Eligibility criteria included the following: amenorrhea longer than 12 months and aged 45 years or older, treated for breast cancer, and metastasis-free for at least 5 years. The control group consisted of women with amenorrhea longer than 12 months and aged 45 years or older and without breast cancer, matched by age and menopause status (in a proportion of 1:2 as sample calculation). Clinical and anthropometric data were collected. Biochemical parameters, including total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, glucose, and C-reactive protein, were measured. Women showing three or more diagnostic criteria were diagnosed as having MetS: waist circumference of 88 cm or larger, blood pressure of 130/85 mm Hg or higher, triglycerides level of 150 mg/dL or higher, high-density lipoprotein cholesterol level lower than 50 mg/dL, and glucose level of 100 mg/dL or higher. For statistical analysis, Student's t test, χ2 test, and logistic regression (odds ratio [OR]) were used. RESULTS: The mean (SD) age of breast cancer survivors was 60.6 (8.6) years, with a mean (SD) follow-up of 9.4 (4.4) years. A higher percentage of breast cancer survivors (46.2%) were obese as compared with controls (32.7%; P < 0.05), and a smaller percentage showed optimal values for low-density lipoprotein cholesterol, glucose, and C-reactive protein versus controls (P < 0.05). MetS was diagnosed in 50% of breast cancer survivors and in 37.5% of control group women (P < 0.05). Among the MetS diagnostic criteria, the most prevalent was abdominal obesity (waist circumference >88 cm), affecting 62.5% and 67.8% of the participants, respectively. In the control group, breast cancer survivors had a higher risk for MetS (OR, 1.66; 95% CI, 1.04-2.68), dysglycemia (OR, 1.05; 95% CI, 1.09-3.03), and hypertension (OR, 1.71; 95% CI, 1.02-2.89). CONCLUSIONS: Postmenopausal breast cancer survivors present a higher risk of developing MetS as compared with women without breast cancer.

Síndrome metabólica em mulheres na pós-menopausa tratadas de câncer de mama / Metabolic syndrome in postmenopausal breast cancer survivors

OBJETIVO: Avaliar a ocorrência de síndrome metabólica (SM) em mulheres na pós-menopausa tratadas de câncer de mama. MÉTODOS: Estudo clínico, transversal, com 158 mulheres na pós-menopausa (amenorreia >12 meses e idade ≥45 anos) tratadas de câncer de mama e livres de doença há pelo menos cinco anos. Por meio de entrevista foram coletados dados clínicos e avaliados o índice de massa corpórea (IMC) e a circunferência da cintura (CC). Na análise bioquímica foram solicitadas dosagens de colesterol total (CT), HDL, LDL, triglicerídeos (TG), glicemia, insulina e proteína C-reativa (PCR). Foram consideradas com SM as mulheres que apresentaram três ou mais critérios diagnósticos: CC>88 cm; TG≥150 mg/dL; HDL colesterol <50 mg/dL; pressão arterial≥130/85 mmHg; glicemia de jejum≥100 mg/dL. Para análise estatística foram empregados o teste t de Student e o teste do χ2. RESULTADOS: A média de idade das pacientes foi de 63,1±8,6 anos, com tempo médio de seguimento de 9,1±4,0 anos. A SM foi diagnosticada em 48,1% (76/158) e entre os critérios diagnósticos, o mais prevalente foi obesidade abdominal (CC>88 cm) afetando 54,4% (86/158) das mulheres. As pacientes sem SM tiveram maior tempo de seguimento quando comparadas àquelas com SM (p<0,05). Em relação ao IMC atual, aquelas sem SM eram em média sobrepeso e aquelas com SM eram obesas (p<0,05). Entre estas, na comparação entre o IMC no momento do diagnóstico do câncer e o atual foi observado ganho significativo de peso (27,8±5,4 versus 33,4±5,4 kg/m²) (p<0,05). O valor médio de PCR foi superior nas mulheres com SM (p<0.05). Na comparação das características tumorais e tratamentos oncológicos não houve diferença significativa entre as mulheres com e sem SM. CONCLUSÃO: Mulheres na pós-menopausa tratadas de câncer de mama têm elevado risco de desenvolver síndrome metabólica e obesidade central.

PURPOSE: To assess the occurrence of metabolic syndrome (MetS) in postmenopausal breast cancer survivors. METHODS: A total of 158 breast cancer survivors were included in this cross-sectional study. Eligibility criteria were: women with amenorrhea >12 months and age ≥45 years, treated for breast cancer and no metastasis for at least five years. Clinical history and anthropometric indicator data (body mass index (BMI), and waist circumference, (WC) were collected. Biochemical parameters, including total cholesterol, HDL, LDL, triglycerides (TG), glucose and C-reactive protein (CRP), were measured. MetS was diagnosed as the presence of at least three of the following diagnostic criteria: WC>88 cm, blood pressure≥130/85 mmHg, triglycerides≥150 mg/dl, HDL <50 mg/dL,and glucose≥100 mg/dL. The Student's t-test and χ2 test were used for statistical analysis. RESULTS: The mean age of breast cancer survivors was 63.1±8.6 years, with a mean follow-up of 9.1±4.0 years. MetS was diagnosed in 48.1% (76/158) and the most prevalent diagnostic criterion was abdominal obesity (WC>88 cm), affecting 54.4% (86/158) of the women. The patients without MetS had a longer follow-up compared those with MetS (p<0.05). Regarding the current BMI, PN average, those without MetS were overweight, and those with MetS were obese (p<0.05). Among the latter, comparison of BMI at the time of cancer diagnosis and current BMI (27.8±5.4 versus 33.4±5.4 kg/m²) showed a significant weight gain (p<0.05). Mean CRP values were higher in women with MetS (p<0.05). In the comparison of tumor characteristics and cancer treatments there was no difference between groups (p>0.05). CONCLUSION: Postmenopausal breast cancer survivors had a higher risk of developing metabolic syndrome and central obesity.
