Purpose
To evaluate the role of mtDNA in breast cancer.Methods
We carried out an investigation into the mtDNA major control region or D-loop region and an essential and the largest mtDNA protein-coding gene, NADH dehydrogenase subunit 5 (ND5), together with a mitochondrial haplogroup analysis in 64 patients with breast cancer (BC) and 54 patients with benign breast disease (BBD) as controls.Results
Mutations in D-loop region were found in 10/64 or 15.6% of patients with BC and 14/54 or 25.9% of patients with BBD, while mutations in ND5 were detected in 6/64 or 9.4% of patients with BC and 5/54 or 9.3% of patients with BBD. In addition, in patients with BBD, mtDNA mutations were more likely to rise in D-loop region and the mutations were more likely to be heteroplasmic. However, in patients with BC, those with metastatic feature were less likely to carry mutations in D-loop region. Finally, we found haplogroup M has an increased risk of breast cancer compared with haplogroup N.Conclusion
mtDNA mutation may play a role in early stage of tumorigenesis, and mitochondrial haplogroup can also modulate breast cancer occurrence. 相似文献2.

Aims/hypothesis
Evidence is emerging of an association between breast cancer and diabetes; however, it is uncertain whether diabetes incidence is increased in postmenopausal breast cancer survivors compared with women without breast cancer. The objective of this study was to determine whether postmenopausal women who develop breast cancer have a higher incidence of diabetes than those who do not develop breast cancer.Methods
We used population-based data from Ontario, Canada to compare the incidence of diabetes among women with breast cancer, aged 55 years or older, from 1996 to 2008, with that of age-matched women without breast cancer. We used Cox proportional hazard models to estimate the effect of breast cancer on the cause-specific hazard of developing diabetes overall and in the subgroup of women who received adjuvant chemotherapy.Results
Of 24,976 breast cancer survivors and 124,880 controls, 9.7% developed diabetes over a mean follow-up of 5.8 years. The risk of diabetes among breast cancer survivors compared with women without breast cancer began to increase 2 years after diagnosis (HR 1.07 [95% CI, 1.02, 1.12]), and rose to an HR of 1.21 (95% CI, 1.09, 1.35) after 10 years. Among those who received adjuvant chemotherapy (n?=?4,404), risk was highest in the first 2 years after diagnosis (HR 1.24 [95% CI 1.12, 1.38]) and then declined.Conclusions/interpretation
We found a modest increase in the incidence of diabetes among postmenopausal breast cancer survivors that varied over time. In most women the risk began to increase 2 years after cancer diagnosis but the highest risk was in the first 2 years in those who received adjuvant therapy. Our study suggests that greater diabetes screening and prevention strategies among breast cancer survivors may be warranted. 相似文献4.

Purpose
Melanoma-associated antigens-A (MAGE-A) family is a group of well-characterized cancer/testis antigens (CTA), because they are strictly tumor specific and are shared by many kinds of tumors. However, the expression pattern of MAGE-A10 and MAGE-A11 in breast cancer patients is still unclear. The purpose of our study is to investigate the expression pattern and prognostic significance of MAGE-A10 and MAGE-A11 in breast cancer patients. 相似文献5.

Purpose
The clinical significance of bilateral breast cancer is unclear and its influence on prognosis is controversial. We compared the characteristics and prognosis of bilateral breast cancer and unilateral breast cancer.Methods
Our study included 4,183 patients with breast cancer who were treated at Sun Yat-sen University Cancer Center between January 1, 2000, and December 31, 2007. Bilateral breast cancer was categorized as synchronous (within 3?months) or metachronous (diagnosed after 3?months of first cancer). SPSS was used for data analysis.Results
106 (2.5%) and 31 (0.7%) patients were diagnosed with metachronous and synchronous bilateral cancer. Women with bilateral cancer had more frequent postmenopause, HER-2 negativity, and advanced disease than in patients with unilateral cancer. Young age at diagnosis, invasive lobular carcinoma, ER/PR negativity, HER-2 positivity, radiation, large tumor size (T?>?5?cm), and stage III disease of the first cancer were risk factors for contralateral cancer. The 5-year disease-free survival and overall survival rates were 76 and 83% for unilateral cancer, while 32 and 72% for bilateral cancer (P?=?0.000 for both).Conclusions
Bilateral cancer was associated with shorter disease-free survival and overall survival than unilateral cancer. The prognosis of metachronous bilateral cancer, especially those diagnosed within 2?years after the first cancer was significantly worse than synchronous bilateral cancer. 相似文献7.

Purpose
Carriers of BRCA1/2 mutations are at high lifetime risk of breast cancer (BC); however, the BC onset broadly vary in individual patients. Recently, polyglutamine (poly-Q) repeat length polymorphism of the amplified in breast cancer 1 (AIB1) gene was analyzed as a risk factor influencing BC onset in BRCA1/2 mutation carriers with contradictory results. 相似文献10.

Purpose
Women with breast cancer that initially involves local lymph nodes have a higher risk for local recurrence or developing metastases. Recent data suggest that germline polymorphism is a significant, previously unrecognized factor in breast cancer progression and metastasis. We assessed the influence of 16 selected common germline polymorphisms in disease-free survival and overall survival among 216 women diagnosed with lymph node-positive breast cancer. 相似文献11.

Breast carcinoma is the most frequent tumor in the female population. Many factors can influence the risk of breast cancer; some of them, such as old age and breast cancer 1/2 (BRCA1/BRCA2) gene mutations, are associated with a fourfold increase in risk. A previous diagnosis of atypical ductal or lobular hyperplasia or having a first-degree relative with a carcinoma are factors associated with a two- to fourfold increase in risk. A relative risk between 1 and 2 is associated with longer exposure to endogenous hormones as a result of early menarche, late menopause and obesity, or with recent and prolonged use of hormone replacement therapy (HRT) or with behavioural factors such as high alcohol and fat intake. Is it possible to modify breast cancer risk in postmenopausal women? Risk factors related to lifestyle can be changed, even if it is not clear whether modifying these behavioural factors during the postmenopausal period will influence the overall breast cancer risk. For instance, the influence of exogenous hormones throughout life (both oral contraceptives and HRT) should be evaluated according to the individual risk-benefit ratio. The problem is even more complex for women who carry genetic mutations and for those who have close relatives with breast cancer, who may be candidates for risk reduction strategies. Prophylactic bilateral mastectomy is still controversial, but is frequently offered to or requested by this group of women and may be indicated in BRCA1/BRCA2 carriers. Chemoprevention with tamoxifen and with the new selective estrogen receptor modulators, namely raloxifene, is very promising and deserves a thorough discussion for all high-risk women. 相似文献

Lifestyle interventions for cardiovascular risk reduction in women with breast cancer 总被引:1,自引:0,他引:1
Purpose
The purpose of this paper is to identify risk factors for cardiovascular disease in women with breast cancer and review healthy lifestyle behaviors as essential risk reduction strategies.Findings
Women with breast cancer account for 22% of the 12 million cancer survivors. Women diagnosed with breast cancer often present with modifiable and non-modifiable cardiovascular risk factors and/or pre-existing co-morbid illness. Any one or a combination of these factors may increase the risk of cardiovascular disease. There is strong evidence that healthy eating and routine physical activity can reduce cardiovascular disease. Exercise improves cardiovascular fitness, body composition and quality of life in breast cancer survivors and observational studies suggest a survival benefit.Clinical Implications:
Lifestyle interventions including a healthy diet, regular physical activity, weight management and smoking cessation should be integrated into a survivorship care plan to reduce cardiovascular disease risk and promote better health for women with breast cancer. 相似文献16.

Purpose
Epidemiological studies indicated that type 2 diabetes mellitus may increase breast cancer risk and mortality. The aim of this retrospective cohort study was to examine the effect of diabetes on the clinical course and the prognosis of early stage breast cancer in relation to tumour and patient characteristics.Methods
The cohort analyzed in this study consisted of 4,056 patients with invasive primary breast cancer. We compared overall survival, distant metastasis-free survival and local recurrence free survival between breast cancer patients with and without diabetes.Results
In our cohort 276 breast cancer patients (6.8%) were affected by diabetes compared to 3,780 patients (93.2%) without diabetes. Women with diabetes were significantly older, had larger tumours, and a higher rate of lymph node involvement. After a follow-up period of 5?years, stratification for age and adjustment for other prognostic factors, overall mortality following breast cancer was significantly higher in diabetic breast cancer patients (hazard ratio, HR 1.92; 95% confidence interval, CI 1.49?C2.48). We found no significant differences in distant metastasis-free survival and local recurrence free survival between the two groups, but we found a slightly significant higher rate of distant metastasis in the group of patients with diabetes and oestrogen receptor negative tumours (HR 2.28; CI 1.31?C3.97).Conclusion
In this study, patients with diabetes and oestrogen receptor negative breast cancer had a more than 2-fold higher risk for distant metastasis compared to patients without diabetes. Diabetes was also associated with an almost 2-fold increase in mortality within the 5?years follow-up period. 相似文献17.

Purpose
The BRCA1-associated RING domain (BARD1) gene has been identified as a high-penetrance gene for breast cancer, whose germline and somatic mutations were reported in both non-BRCA1/2 hereditary site-specific and sporadic breast cancer cases. Some association studies suggested that the BRAD1 Cys557Ser variant might be associated with increased risk of breast cancer, but the results remain conflicting rather than conclusive. In order to derive a more precise estimation of the relationship, this meta-analysis was performed. 相似文献18.

Background
Breast cancer screening with magnetic resonance imaging (MRI) may be a useful adjunct to screening mammography in high-risk women, but MRI uptake may be increasing rapidly among low- and average-risk women for whom benefits are unestablished. Comparatively little is known about use of screening MRI in community practice.Objective
To assess relative utilization of MRI among women who do and do not meet professional society guidelines for supplemental screening, and describe utilization according to breast cancer risk indications.Design
Prospective cohort study conducted between 2007 and 2014.Participants
In five regional imaging registries participating in the Breast Cancer Surveillance Consortium (BCSC), 348,955 women received a screening mammogram, of whom 1499 underwent screening MRI.Main measures
Lifetime breast cancer risk (< 20% or ≥ 20%) estimated by family history of two or more first-degree relatives, and Gail model risk estimates. Breast Imaging Reporting and Data System breast density and benign breast diseases also were assessed. Relative risks (RR) for undergoing screening MRI were estimated using Poisson regression.Key results
Among women with < 20% lifetime risk, which does not meet professional guidelines for supplementary MRI screening, and no first-degree breast cancer family history, screening MRI utilization was elevated among those with extremely dense breasts [RR 2.2; 95% confidence interval (CI) 1.7–2.8] relative to those with scattered fibroglandular densities and among women with atypia (RR 7.4; 95% CI 3.9–14.3.) or lobular carcinoma in situ (RR 33.1; 95% CI 18.0–60.9) relative to women with non-proliferative disease. Approximately 82.9% (95% CI 80.8%–84.7%) of screening MRIs occurred among women who did not meet professional guidelines and 35.5% (95% CI 33.1–37.9%) among women considered at low-to-average breast cancer risk.Conclusion
Utilization of screening MRI in community settings is not consistent with current professional guidelines and the goal of delivery of high-value care.19.
