Tumor necrosis factor-α-induced protein 8 (TNFAIP8), a transcription factor NF-κB-inducible, antiapoptotic and oncogenic molecule, is associated with prognosis of several human malignancies. However, the relationship between TNFAIP8 and the prognosis of the invasive ductal carcinoma (IDC) of the breast remains unclear. TNFAIP8 expression was evaluated using real-time PCR and Western blot analysis in 20 fresh IDC tissues, and immunohistochemical analysis in 351 paraffin-embedded IDC tissues. Real-time PCR and Western blot analysis demonstrated that both TNFAIP8 mRNA and protein were upregulated in IDC tissues compared with the paired adjacent noncancerous tissues...

Digital whole slide imaging is an increasingly common medium in pathology, with application to education, telemedicine, and rendering second opinions. It has also made it possible to use eye tracking devices to explore the dynamic visual inspection and interpretation of histopathological features of tissue while pathologists review cases. Using whole slide images, the present study examined how a pathologist's diagnosis is influenced by fixed case-level factors, their prior clinical experience, and their patterns of visual inspection...

We have previously shown that Rab17 - a small GTPase associated with epithelial polarity - is specifically suppressed by ERK2 signalling to promote an invasive phenotype. However, the mechanisms through which Rab17 loss permits invasiveness, and the endosomal cargoes that are responsible for mediating this are not known. Using quantitative mass spectrometry-based proteomics, we have found that knockdown of Rab17 leads to highly selective reduction in the cellular levels of a v-SNARE (Vamp8). Moreover, proteomics and immunofluorescence indicate that Vamp-8 is associated with Rab17 at late endosomes...

This review paper analyzed publications of adjuvant tamoxifen and aromatase inhibitor use following surgery for breast ductal carcinoma in situ (DCIS). Key endpoint analyses were risk of invasive and noninvasive malignancies and new contralateral breast cancers. Metaanalysis of three studies showed a relative risk of 0.69 (95% confidence interval, 0.60-0.79, P<0.05) for breast malignancies with tamoxifen treatment in a mixed radiotherapy treatment/naïve cohort. Subgroup analysis of DCIS populations in multiple studies showed a trend to benefit with aromatase inhibitor treatment...

Extramammary Paget's disease (EMPD) is a rare disease which is found in apocrine-rich locations such as anogenital region, axilla and rarely in other sites. Perianal EMPD is often reported as the involvement of perianal skin, but involvement of anal mucosa is very rare. Based on pathogenesis and association with either synchronous or metachronous malignancy, EMPD can be divided into primary and secondary types. Treatment approach for these two types of Paget's disease and their prognosis is different, thus it is important to make the distinction...

Homeobox A11 (HOXA11) is one of the hypermethylated genes in breast cancer and its function in breast tumorigenesis remains elusive. In this study, we analyzed the methylation status of HOXA11 in 264 paired breast cancer and normal tissue as well as in matched serum samples by MethyLight assay. Further, the function of HOXA11 in breast tumorigenesis was analyzed by cell proliferation and migration assays. We found that HOXA11 was hypermethylated in cancer tissues (45.08%), especially in invasive ductal carcinomas (P<0...

NADPH oxidase (NOX) generates reactive oxygen species (ROS) and has been suggested to mediate cell proliferation in some cancers. Here, we show that an increase in the expression of NOX5 long form (NOX5-L) is critical for tumor progression in breast tumor tissues. Immunostaining of clinical samples indicated that NOX5 was overexpressed in 41.1% of breast ductal carcinoma samples. NOX5-L depletion consistently suppressed cell proliferation, invasion, and migration in vitro. Antibody-mediated neutralization of NOX5-L attenuated tumor progression in a mouse xenograft model...

AIMS: The 2013 ASCO/CAP HER2 guidelines recommend testing all invasive breast cancers for HER2, typically with IHC followed by ISH when IHC is equivocal. As well-differentiated breast cancers are rarely HER2 positive, we assessed the value of routine reflex HER2 ISH testing for this subset of breast cancers. METHODS AND RESULTS: We collected HER2 IHC 2+ cases and FISH data from primary breast cancers with well-differentiated tumor types (grade 1 ductal carcinomas, classic lobular carcinomas, tubular, cribriform and pure mucinous carcinomas) at our centre from 2010-2015...

The first patient was a 62-year-old woman who was referred to our hospital with the complaint of a left breast tumor. She was diagnosed with invasive ductal carcinoma(T1N0M0, stage I). The tumor was ER-positive, PgR-negative, and HER2- negative. She was treated with toremifene, letrozole, and anastrozole as neoadjuvant hormone therapy for 4 months, but the tumor increased in size. The clinical response was judged as progressive disease, and a left partial mastectomy and axillary lymph node dissection were performed...

BACKGROUND: Fat transfer is an increasingly popular method for refining postmastectomy breast reconstructions. However, concern persists that fat transfer may promote disease recurrence. Adipocytes are derived from adipose-derived stem cells and express adipocytokines that can facilitate active breast cancer cells in laboratory models. The authors sought to evaluate the association between fat transfer to the reconstructed breast and cancer recurrence in patients diagnosed with local or regional invasive breast cancers...

Adenoid cystic carcinoma of the breast (breast-ACC) is a rare and indolent tumor with a good prognosis despite its triple-negative status. However, we observed different outcomes in the present study. Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, we enrolled a total of 89,937 eligible patients with an estimated 86 breast-ACC cases and 89,851 invasive ductal carcinoma (IDC) patients. In our study, breast-ACC among women presented with a higher proportion of triple-negative breast cancer (TNBC), which was more likely to feature well-differentiated tumors, rare regional lymph node involvement and greater application of breast-conserving surgery (BCS)...

Importance: Compared with white American (WA) women, African American (AA) women have a 2-fold higher incidence of breast cancers that are negative for estrogen receptor, progesterone receptor, and ERBB2 (triple-negative breast cancer [TNBC]). Triple-negative breast cancer, compared with non-TNBC, likely arises from different pathogenetic pathways, and benign breast disease (BBD) predicts future non-TNBC. Objective: To determine whether AA identity remains associated with TNBC for women with a prior diagnosis of BBD...

Importance: New techniques for preoperative localization of nonpalpable breast lesions may decrease the reoperation rate in breast-conserving surgery (BCS) compared with rates after surgery with the standard wire-guided localization. However, a valid reoperation rate for this procedure needs to be established for comparison, as previous studies on this procedure include a variety of malignant and benign breast lesions. Objectives: To determine the reoperation rate after wire-guided BCS in patients with histologically verified nonpalpable invasive breast cancer (IBC) or ductal carcinoma in situ (DCIS) and to examine whether the risk of reoperation is associated with DCIS or histologic type of the IBC...
