At some tertiary breast care centers, where many patients are referred from other institutions, it is routine to repeat testing for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2/neu) in excision specimens if these tests were performed on the preceding biopsy at the referring facility. The goal of this study is to assess the value of this practice. We documented results from ER, PR, and HER2 testing in 541 consecutive invasive breast cancers excised over a 2...

Secretory carcinomas of the breast are rare tumors with distinct histologic features, recurrent t(12;15)(p13;q25) translocation resulting in ETV6-NTRK3 gene fusion and indolent clinical behavior. Mammary analog secretory carcinomas arising in other sites are histopathologically similar to the breast tumors and also harbor ETV6-NTRK3 fusions. Breast secretory carcinomas are often triple (estrogen and progesterone receptor, HER2) negative with a basal-like immunophenotype. However, genomic studies are lacking, and whether these tumors share genetic features with other basal and/or triple negative breast cancers is unknown...

According to the St. Gallen 2011 consensus, proper qualification of breast cancer patients for treatment requires taking into consideration the division into biological types of neoplasms. The goal of this work was to assess the prevalence of all biological types of breast cancer in the population of Kuyavian-Pomeranian province. We determined the influence of particular types of neoplasms on the degree of disease progression and the choice of therapeutic management. The study was conducted on a group of 2653 patients treated surgically due to malignant breast tumors in the Oncology Centre in Bydgoszcz...

BACKGROUND: Terminal duct lobular unit (TDLU) involution is a physiological process of breast tissue aging characterized by a reduction in the epithelial component. In studies of women with benign breast disease, researchers have found that age-matched women with lower levels of TDLU involution are at increased risk of developing breast cancer. We previously showed that breast cancer cases with core basal phenotype (CBP; estrogen receptor negative [ER(-)], progesterone receptor-negative [PR(-)], human epidermal growth factor receptor 2-negative [HER2(-)], cytokeratins (CK 5 or CK5/6)-positive [CK5/6(+)] and/or epidermal growth factor receptor-positive [EGFR(+)]) tumors had significantly reduced TDLU involution compared with cases with luminal A (ER(+) and/or PR(+), HER2(-), CK5/6(-), EGFR(-)) tumors from a population-based case-control study in Poland...

PURPOSE: It is well-known that tumor phenotype may change during the progression of breast cancer (BC). The purpose in this study was to compare the discordance in estrogen receptor (ER), progesterone receptor (PgR) and human epidermal growth factor receptor 2 (HER2) between primary and recurrent/metastatic lesions (RML) and also to evaluate the prognostic significance of change in tumor phenotype on survival in patients with metastatic BC. METHODS: The medical records of 6638 patients with BC from two breast centers treated between 1992 and 2015 were retrospectively analyzed...

Total choline (tCho) was documented as a biomarker for breast cancer diagnosis by in vivo MRS. To understand the molecular mechanisms behind elevated tCho in breast cancer, an association of tCho with β-catenin and cyclin D1 was evaluated. Hundred fractions from 20 malignant, 10 benign and 20 non-involved breast tissues were isolated. Cytosolic and nuclear expressions of β-catenin and cyclin D1 were estimated using ELISA. Higher tCho was seen in malignant compared to benign tissues. Malignant tissues showed higher cytosolic and nuclear β-catenin expressions than benign and non-involved tissues...

Background: Preclinical evidence indicates that increased insulin-like growth factor receptor-1 (IGF1R) signaling interferes with the action of trastuzumab suggesting a possible mechanism of trastuzumab resistance. Thus, we evaluated IGF1R prevalence, relationship with demographic data, and association with disease-free survival (DFS) of patients randomized to chemotherapy alone (Arm A) or chemotherapy with sequential (Arm B) or concurrent trastuzumab (Arm C) in the prospective phase III HER2(+) adjuvant N9831 trial...

Donita Africander, Karl-Heinz Storbeck
It is well-known that breast cancer is hormone-dependent and that steroid hormones exert their mitogenic effects by binding to estrogen, progesterone and androgen receptors. Vital to our understanding and treatment of this malignancy, is the local metabolism of steroid hormones in breast cancer tissue. This review summarises our current knowledge on steroid producing pathways in the adrenal, ovary and breast, while focussing on the availability of specific circulating hormone precursors and steroidogenic enzymes involved in the local synthesis and metabolism of steroid hormones in the breast...

PURPOSE: Endocrine therapies, including tamoxifen or aromatase inhibitors, are indispensable for the treatment of patients with estrogen receptor (ER)- and/or progesterone-positive breast cancer. Whereas tamoxifen displays partial ER agonistic effects in bone, aromatase inhibitors increase bone resorption and fracture risk. The Wnt inhibitors dickkopf-1 (DKK-1) and sclerostin negatively impact bone formation and are considered targets for the treatment of bone disorders. However, the effect of endocrine therapies on serum DKK-1 and sclerostin levels in patients with primary breast cancer remains elusive...

Breast cancer (BC) biology is of outmost importance for its therapeutic management and for establishing patients' outcome. Breast cancer has been divided in subtypes depending on the presence of hormone receptors (HRs) for estrogen and progesterone and human epidermal growth factor receptor 2 (HER2) gene amplification. Recently, a distinct subcategory has been analyzed from the group of HER2-enriched BC with positive HR, namely HER2 positive with high levels of hormone receptor expression, suggestively named "triple positive" breast cancer...

Triple-negative breast cancer (TNBC) indicates a subset of breast carcinomas that does not express estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2). According to the literature, TNBCs are aggressive tumors, characterized by a high incidence of recurrence and a high risk of disease progression. Lactoferrin (LF) is a single-chain, iron-binding glycoprotein of ~700 amino acids, which is involved in a wide range of biological activities, including iron-trafficking and carcinogenesis...

All patients with early breast cancer should be classified by subgroup through testing estrogen receptor, progesterone receptor, and HER2 status, with or without Ki-67 proliferation percentage. Genomic expression profiling aids clinical decision-making in most patients, because most are estrogen receptor-positive. The commercially available classifiers are prognostic for distant recurrence in node-negative and also node-positive patients. Patients at genomically low risk have excellent 5-year outcomes with endocrine therapy alone...

The beneficial versus detrimental roles of estrogen plus progesterone (E+P) in breast cancer remains controversial. Here we report a beneficial mechanism of E+P treatment in breast cancer cells driven by transcriptional upregulation of the NFκB modulator NEMO, which in turn promotes expression of the tumor suppressor protein PML. E+P treatment of patient-derived epithelial cells derived from ductal carcinoma in situ (DCIS) increased secretion of the pro-inflammatory cytokine IL-6. Mechanistic investigations indicated that IL-6 upregulation occurred as a result of transcriptional upregulation of NEMO, the gene for which harbored estrogen receptor (ER) binding sites within its promoter...

Primary breast cancer fairly infrequently occurs in ectopic breast tissue, and primary ectopic breast cancer of the vulva is particularly rare. Only 26 cases have been published in the English-language literature, and there has been no report of primary breast carcinoma of the vulva in Japan. We report a rare case of primary ectopic breast cancer of the vulva that was treated with local excision of the vulva and sentinel lymph node biopsy (SLNB). The patient was a 72-year-old woman who had noticed a right vulvar tumor 10 years earlier...
