BACKGROUND: Invasive apocrine adenocarcinoma (AAC) of breast is a rare histopathological subtype of breast carcinomas. We aim to investigate the different characteristics and prognostic outcomes between AAC and invasive ductal carcinoma (IDC) of breast cancer. RESULTS: AAC patients presented with older ages, more aggressive behaviors, lower ER and PR proportions, higher HER2 amplification rates and less application of breast-conserving therapy and adjuvant chemotherapy compared to IDC patients...

Machine learning systems have recently received increased attention for their broad applications in several fields. In this study, we show for the first time that histological types of breast tumors can be classified using subtle morphological differences of microenvironmental myoepithelial cell nuclei without any direct information about neoplastic tumor cells. We quantitatively measured 11661 nuclei on the four histological types: normal cases, usual ductal hyperplasia and low/high grade ductal carcinoma in situ (DCIS)...

Pseudogenes have been reported to exhibit functional roles. Amplification or overexpression of CDC28 protein kinase regulatory subunit 1B (CKS1B) was found in various human cancers. But it was known little about CKS1B pseudogene 7 (CKS1BP7), a pseudogene sharing considerable sequence identity with CKS1B. The aim of this study was to evaluate copy number alterations (CNAs) of CKS1BP7 and address its potential roles in breast cancer. We detected copy numbers of CKS1BP7 and insulin-like growth factor 1 receptor (IGF1R) using quantitative multi-gene fluorescence in situ hybridization (QM-FISH) technique, compared their status in both invasive carcinoma and ductal carcinoma in situ (DCIS) components within the same tumors, and investigated the associations of CNAs with tumor features and patients outcomes...

GOAL: This research aims to validate a new biomarker of breast cancer by introducing electromechanical coupling factor of breast tissue samples as a possible additional indicator of breast cancer. Since collagen fibril exhibits a structural organization that gives rise to a piezoelectric effect, the difference in collagen density between normal and cancerous tissue can be captured by identifying the corresponding electromechanical coupling factor. METHODS: The design of a portable diagnostic tool and a microelectromechanical systems(MEMS)- based biochip, which is integrated with a piezoresistive sensing layer for measuring the reaction force as well as a microheater for temperature control, is introduced...

Small invasion into ductal carcinoma in situ (DCIS) can easily be overlooked in resected breast specimens. To disclose useful markers predictive of invasive foci within preoperatively diagnosed DCIS lesions, a retrospective histopathological comparison was made between postoperatively diagnosed invasive ductal carcinoma with a predominant intraductal component (IDCPIC) (n=43) and pure DCIS (n=82). Through a multivariate logistic regression analysis model, 5 variables (DCIS grade, "tumor thickness", extent of retraction cleft, presence of lymph node metastasis, and HER2 score) were found to be significantly associated with the presence of invasive foci within DCIS; with a cutoff point of 0...

Breast cancers are the most common cancers in women. However, breast cancer occurring in a pectoralis major myocutaneous flap is extremely rare. This article describes a case of breast cancer occurring in such a flap used for reconstruction of the tongue in a 72-year-old woman. Follow-up computed tomogram depicted a slowly growing mass in the flap. Thirty-nine months postoperatively, a fine-needle aspiration biopsy specimen taken from the lesion suggested glandular carcinoma. The patient was diagnosed with breast cancer in the neck area of the flap and tumor excision was performed...

Here we report the identification and characterization of a novel high molecular weight isoform of tropomyosin, Tpm4.1, expressed from the human TPM4 gene. Tpm4.1 expression is down-regulated in a subset of breast cancer cells compared with untransformed MCF10A breast epithelial cells and in highly metastatic breast cancer cell lines derived from poorly metastatic MDA-MD-231 cells. In addition, patients with invasive ductal breast carcinoma show decreased TPM4 expression compared with patients with ductal breast carcinoma in situ, and low TPM4 expression is associated with poor prognosis...

Breast cancers are solid tumors frequently characterized by regions with low oxygen concentrations. Cellular adaptations to hypoxia are mainly determined by "hypoxia inducible factors" that mediate transcriptional modifications involved in drug resistance and tumor progression leading to metastasis and relapse occurrence. In this study, we investigated the prognostic value of hypoxia-related gene expression in breast cancer. A systematic review was conducted to select a set of 45 genes involved in hypoxia signaling pathways and breast tumor progression...

PURPOSE: To explore the correlation between tumor-infiltrating immune cell subsets and breast cancer prognosis. MATERIALS AND METHODS: Specimens of 102 patients with invasive ductal carcinoma of the breast were analyzed for immune-related markers (CD8, CD20, FOXP3 and CD68). The number of positive cells in the 3 most highly stained intratumoral stroma areas of the primary tumor was counted. The mean number was calculated and used to divide patients into 2 groups for each marker (CD8-high/CD8-low, CD20-high/CD20-low, FOXP3-high/FOXP3-low, and CD68-high/CD68-low)...

Breast carcinomas have been classified from the molecular point of view into four major groups (Luminal A, Luminal B, HER2 and triple negative). However, these groups are not homogeneous and there is a need to establish subcategories that can be identified by immunohistochemistry (IHC), to better predict prognosis and carry out treatments that are more effective. This study was conducted in 354 patients diagnosed with invasive ductal breast carci- noma. The expression of 22 molecules was analyzed by tissue matrices and the results obtained were compared with molecular classes defined by IHC, according to the expression of estrogen receptor (ER), progesterone receptor (PR) and HER2, and the overall survival...

BACKGROUND: T regulatory cells (Tregs) are known to negatively control immune response. The frequency of these cells was inversely correlated with clinical outcomes of breast cancer. CD19(+)CD24(hi)CD38(hi) cells also play a critical role in inflammation and autoimmune disease. However, their function in tumor immune response is less studied. In this study we aimed to determine the role of CD19(+)CD24(hi)CD38(hi) cells and some other clinicopathological variables in increasing the proportion of Tregs in breast cancer patients...

Although most human cancers display a single histology, there are unusual cases where two or more distinct tissue types present within a primary tumor. One such example is metaplastic breast carcinoma, a rare but aggressive cancer with a heterogenous histology, including squamous, chondroid, and spindle cells. Metaplastic carcinomas often contain an admixed conventional ductal invasive or in situ mammary carcinoma component, and are typically triple-negative for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 (HER-2) amplification/overexpression...
