PURPOSE: Mortality reduction attributable to organized breast screening is modest. Screening may be less effective at detecting more aggressive cancers at an earlier stage. This study was conducted to determine the relative efficacy of screening mammography to detect cancers at an earlier stage by molecular phenotype. METHODS: We identified 2882 women with primary invasive breast cancer diagnosed between January 1, 2008 and December 31, 2012 and who had a mammogram through the Ontario Breast Screening Program in the 28 months before diagnosis...

BACKGROUND: Recent investigations have indicated that hormone therapy may increase the risk of breast cancer (BC), and the addition of synthetic progestins may play a critical role in this. Several studies have pointed out the important role of progesterone receptor membrane component 1 (PGRMC1) in the development of BC, especially with hormone therapy using progestins. Although the deregulation of microRNA-181a (miR-181a) is often associated with human BC, the effect of miR-181a on PGRMC1 expression during hormone therapy has not been investigated...

Interleukin-10 (IL-10), interleukin-17A (IL-17A) and transforming growth factor α (TGF-α) have been implicated in the progression of breast cancer. However, the diagnostic and prognostic roles of these cytokines in ductal carcinoma remain unclear. The present study therefore aimed to determine the serum levels of IL-10, IL-17 and TGF-α in subjects with benign and malignant breast diseases and to evaluate the clinical significance of these cytokines in ductal carcinoma. Pre-operative serum samples were collected from 378 patients with breast disease and 70 healthy subjects...

Androgen receptor (AR) expression is an emerging prognostic marker that has been observed in 25% to 75% of triple negative breast cancers (TNBCs) that lack estrogen receptor, progesterone receptor and HER2 overexpression. TNBCs are treated with AR-targeted therapies and standardized evaluation of AR expression may help guide patient management. Basal-like TNBCs are a subgroup of TNBCs defined by positive immunoreactivity for CK5/6 or EGFR that carry a worse prognosis. However, it's unclear whether basal-like TNBCs have a different rate of AR positivity or if AR expression is predictive of disease free survival in this patient group...

Breast cancer is the most common malignancy affecting women, but the heterogeneity of the condition is a significant obstacle to effective treatment. Triple negative breast cancers (TNBCs) do not express HER2 or the receptors for estrogen or progesterone, and so often have a poor prognosis. Tumor-infiltrating T cells have been well-characterized in TNBC, and increased numbers are associated with better outcomes; however, the potential roles of B cells and plasma cells have been large. Here, we conducted a retrospective correlative study on the expression of B cell/plasma cell-related genes, and the abundance and localization of B cells and plasma cells within TNBCs, and clinical outcome...

Aim: Routine assessment of cell proliferation is recommended in the pathologic evaluation for all breast cancers. Considering the poor reproducibility and interobserver variability in mitotic counts, Ki-67 is an easily available and reliable substitute for mitotic counts and has been shown to have a significant relationship with the histologic grade of malignancy and the mitotic activity of tumors. Our study aimed at exploring Ki-67 expression and studying its correlation with other established prognostic parameters...

OBJECTIVES: Human papilloma virus (HPV) has been implicated in several types of epithelial cancer. The role of HPV in breast carcinogenesis has been a matter of debate fueled by conflicting reports in recent years. The aim of this study is to identify the prevalence of breast and cervical HPV infection in cancer patients by using a modern microarray approach. MATERIALS AND METHODS: In the present prospective study, 201 breast cancer patients were included. For each patient a detailed medical history was taken and during the operation, under sterile conditions, samples were collected, from the tumour, the healthy adjacent breast tissue and any positive sentinel lymph nodes...

A 34-year-old primigravid woman presents for a routine prenatal visit at 18 weeks of gestation with a breast lump. On examination, she has a painless, firm breast mass measuring 3-4 cm in diameter with overlying skin dimpling. A diagnostic mammogram shows findings suspicious for malignancy (Breast Imaging Reporting and Data System [BI-RADS] 4), and core biopsy demonstrates an invasive ductal carcinoma with both estrogen and progesterone receptor-positive staining. The patient asks: "How will this affect my pregnancy, and what is the safest course of action?"...

INTRODUCTION: Hormone receptor and human epidermal growth factor receptor 2 (HER2) status is important for breast cancer (BC) treatment. Previous studies have shown that the long-term treatment outcomes of BC are significantly impaired by the development of subsequent malignancies. Therefore, in the present study, we evaluated the effect of hormone receptor/HER2 status on subsequent malignancies in breast cancer survivors. METHODS AND MATERIALS: The Surveillance, Epidemiology, and End Results*Stat database (8...

Male breast cancer (MBC) accounts for approximately 1% of all breast cancers, limiting the data characterizing clinicopathologic features and treatment outcomes in patients with MBC. This paucity of data has led to most of our treatment guidance being extrapolated from patients with female breast cancer (FBC). From 1998 to 2012, data were captured using the National Cancer Database to identify patients with nonmetastatic MBC (n = 23 305) and FBC (n = 2 678 061). Tumor and clinicopathologic features were obtained and compared...

Hereditary breast cancers in BRCA1-mutation carriers are mostly estrogen receptor alpha (ERα) and progesterone receptor (PR) negative, however, hormone depletion via bilateral oophorectomy does result in a marked reduction of breast cancer risk, suggesting that BRCA1-associated breast tumorigenesis is dependent on hormone signaling. We used genetically engineered mouse models to dissect the individual influences of ERα and PR signaling in the development of BRCA1-deficient breast cancer. In line with the human data, BRCA1-deficient mouse mammary tumors are ERα-negative and bilateral ovariectomy leads to abrogation of mammary tumor development...

Overexpression of anti-apoptotic proteins belonging to the B cell lymphoma (Bcl)-2 family is observed in numerous cancer types and has been postulated to promote cancer cell survival and chemotherapy resistance. Bcl-extra large (xL) /myeloid cell leukemia sequence (Mcl)-1 was demonstrated to be expressed at relatively high levels in clinically aggressive basal-like cancers and inhibiting Bcl-xL overexpression could potentially provoke cell death. A molecule able to target Bcl-xL /Mcl-1, JY-1-106, is herein under investigation...

BACKGROUND/AIM: Sentinel lymph node biopsy (SLNB) has replaced axillary lymph node dissection (ALND) for axillary staging in patients with early-stage breast cancer. The need for therapeutic ALND is the subject of ongoing debate especially after the publication of the ACOSOG Z0011 trial. In a retrospective trial with univariate and multivariate analyses, factors predictive of sentinel lymph node involvement should be analyzed in order to define tumor characteristics of breast cancer patients, where SLNB should not be spared to receive important indicators for adjuvant treatment decisions (e...

Triple Negative Breast Cancer (TNBC) is a highly heterogeneous subtype of breast cancer that lacks the expression of oestrogen receptors, progesterone receptors and human epidermal growth factor receptor 2. Although TNBC is sensitive to chemotherapy, the overall outcomes of TNBC are worse than for other breast cancers, and TNBC is still one of the most fatal diseases for women. With the discovery of antigens specifically expressed in TNBC cells and the developing technology of monoclonal antibodies, chimeric antigen receptors and cancer vaccines, immunotherapy is emerging as a novel promising option for TNBC...
