BACKGROUND: SOX10 is a newer Schwannian and melanocytic marker that has generated great interest for its relative sensitivity and specificity in the diagnosis of neural crest-derived tumors. Previous studies with SOX10 have shown positive immunohistochemical expression in cutaneous eccrine glands and negative expression in eccrine ducts, apocrine glands, and hair follicles. Thus, we hypothesized that some sweat gland tumors of presumed eccrine origin would be positive for SOX10, whereas apocrine-derived sweat gland tumors would not...

Pancreatic cancer is considered one of the most lethal cancers being the fourth leading cause of cancer deaths in adults in the United States because of the lack of early signs and symptoms and the lack of early detection. Pancreatic ductal adenocarcinoma (PDAC) is the most common histological type among pancreatic cancers, representing 80%-90% of all solid tumors of the pancreas. The majority of PDAC develops from three precursor lesions: pancreatic intraepithelial neoplasia, intraductual papillary mucinous neoplasm and mucinous cystic neoplasm...

BACKGROUND: Due to increased rates of curative tumor resections exceeding 60% after FOLFIRINOX-treatment, neoadjuvant therapy/NTx is increasingly recognized as an effective therapy option for downstaging borderline or locally advanced pancreatic ductal adenocarcinoma/PDAC. Yet, the effects of NTx on the common histopathological features of PDAC have not been systematically analysed. Therefore, the aim of the current study was to assess the impact of NTx on relevant histopathological features of PDAC...

OBJECTIVE: To investigate the relationship between CT imaging findings and DPC4 gene expression and determine the prognostic value of DPC4 gene expression to predict overall survival in patients with pancreatic ductal adenocarcinoma. METHODS: Between January and December 2011, we retrospectively analyzed 163 pancreatic ductal adenocarcinomas in 163 patients who had undergone surgical resection (mean age=61.8 years; range=35-81 years). We divided the study patients into 2 groups according to DPC4 gene expression: DPC4-expression or DPC4-non-expression group...

In the present study, to investigate the potential molecular mechanism of pancreatic ductal adenocarcinoma (PDAC), mRNA and miRNA expression profiles were integrated for systematic analysis. Results showed that a total of 76 common differentially expressed genes (DEGs) were identified from 2 mRNA expression profiles that contained 39 tumor and 15 normal samples. Notably, the tumor and normal samples were able to be clearly classified into 4 groups based on the DEGs. mRNA‑miRNA regulation network analysis indicated that 22 out of the 76 DEGs including MUC4, RRM2 and CCL2 are regulated by 5 reported miRNAs...

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignant tumors of the digestive system, but the mechanisms of its development and progression are unclear. Inflammation is thought to be fundamental to pancreatic cancer development and caffeic acid phenethyl ester (CAPE) is an active component of honey bee resin or propolis with anti-inflammatory and anticancer activities. We investigated the inhibitory effects of CAPE on cell growth and migration induced by human neutrophil elastase (HNE) and report that HNE induced cancer cell migration at low doses and growth at higher doses...

The spectrum of genomic alterations in ductal carcinoma in situ (DCIS) is relatively unexplored, but is likely to provide useful insights into its biology, its progression to invasive carcinoma and the risk of recurrence. DCIS (n=20) with a range of phenotypes was assessed by massively parallel sequencing for mutations and copy number alterations and variants validated by Sanger sequencing. PIK3CA mutations were identified in 11/20 (55%), TP53 mutations in 6/20 (30%), and GATA3 mutations in 9/20 (45%). Screening an additional 91 cases for GATA3 mutations identified a final frequency of 27% (30/111), with a high proportion of missense variants (8/30)...

Intrahepatic cholangiocarcinomas were classified into two types based on their microscopic appearance. Tumors with histologic similarities to hilar cholangiocarcinomas (predominantly ductal adenocarcinomas with minor tubular components, if present, restricted to the invasive front) were defined as the perihilar type, whereas the others were classified as peripheral cholangiocarcinomas. Among the 47 cases examined in the present study, 26 (55%) were classified as the perihilar type, whereas 21 (45%) were the peripheral type...

OBJECTIVE: To describe accurately the pattern, timing, and predictors of disease recurrence after a potentially curative resection for pancreatic ductal adenocarcinoma (PDAC). SUMMARY BACKGROUND DATA: After surgery for PDAC, most patients will develop disease recurrence. Understanding the patterns and timing of disease failure can help guide improvements in therapy. METHODS: Patients who underwent pancreatectomy for PDAC at the Johns Hopkins Hospital between 2000 and 2010 were included...

We examined the immunologic effects of allogeneic hematopoietic stem cell transplantation (HSCT) in the treatment of pancreatic ductal adenocarcinoma, a deadly disease with a median survival of 24 months for resected tumors and a 5-year survival rate of 6%. After adjuvant chemotherapy, 2 patients with resected pancreatic ductal adenocarcinoma underwent HSCT with HLA-identical sibling donors. Comparable patients who underwent radical surgery, but did not have a donor, served as controls (n=6). Both patients developed humoral and cellular (ie, HLA-A*01:01-restricted) immune responses directed against 2 novel tumor-associated antigens (TAAs), INO80E and UCLH3 after HSCT...

OBJECTIVES: Axillary ultrasound with fine needle aspiration (AXUSFNA) in early-stage breast cancer has required reappraisal. ACOSOG Z-0011 and after mapping of the axilla: radiotherapy or surgery have shown that women with limited nodal disease at sentinel lymph node biopsy got no survival advantage with completion axillary node dissection. We hypothesize that AXUSFNA may be sufficiently accurate for staging for some patients and sentinel lymph node biopsy need not be performed. We define the false negative rate (FNR) of AXUSFNA in different subsets of patients...

Invasive biliary tract carcinomas are usually tubular adenocaricnomas with abundant desmoplastic reactions and frequent ductal and periductal invasion at the time of the diagnosis. Recently, several intraductal neoplasms of the bile duct, particularly at a pre-invasive stage, have been recognized. They include intraductal papillary neoplasm of the bile duct (IPNB), biliary intraepithelial neoplasm (BilIN), and others, such as intraductal tubulopapillary neoplasm (ITPN) of the bile duct. IPNBs are grossly visible predominantly intraductal-growing papillary neoplasms covered by well-differentiated neoplastic epithelium with fine fibrovascular cores in the dilated bile ducts...

PURPOSE: To determine the levels of aromatase in atypical ductal hyperplasia (ADH) lesions, tissue surrounding the ADH, and in dense and non-dense normal breast tissue. We postulated that excess aromatase in breast tissue might, through production of increased estrogen, drive the carcinogenic process. Estrogens and their metabolites are thought to contribute to the development of breast cancer through estrogen receptor-mediated mechanisms and genotoxic effects of estrogen metabolites...

Balloon-assisted endoscopic retrograde cholangiopancreatoscopy (ERCP) in Roux-en-Y gastric bypass (RYGB) patients is technically challenging due to anatomic and accessory constraints, thus success rates are modest. Transgastric ERCP (TG-ERCP) offers a viable alternative. We aimed to systematically review the literature on TG-ERCP in RYGB patients to better define the technical approaches, success rates, and adverse events of this procedure. A computer-assisted search of the Embase and PubMed databases was performed to identify studies that focused on the techniques and clinical outcomes of TG-ERCP...

BACKGROUND: Sentinel lymph node biopsy (SLNB) should be performed in patients with ductal carcinoma in situ (DCIS) undergoing mastectomy. Yet, the same logic is controversial in the setting of prophylactic mastectomy. METHODS: Surgeons were surveyed as to their practices. Statistical analyses were performed to identify associated factors. RESULTS: 238 surgeons responded to the survey. 73.1% of respondents stated they would always perform SLNB in the setting of mastectomy for DCIS, but only 6...

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal disease for a multitude of reasons including very late diagnosis. This in part is due to the lack of understanding of the biological behavior of PDAC and the ineffective screening for this disease. Significant efforts have been dedicated to finding the appropriate serum and imaging biomarkers to help early detection and predict response to treatment of PDAC. Carbohydrate antigen 19-9 (CA 19-9) has been the most validated serum marker and has the highest positive predictive value as a stand-alone marker...

Formalin-fixed paraffin-embedded (FFPE) specimens, when used in conjunction with patient clinical data history, represent an invaluable resource for molecular studies of cancer. Even though nucleic acids extracted from archived FFPE tissues are degraded, their molecular analysis has become possible. In this study, we optimized a laboratory-based next-generation sequencing barcoded cDNA library preparation protocol for analysis of small RNAs recovered from archived FFPE tissues. Using matched fresh and FFPE specimens, we evaluated the robustness and reproducibility of our optimized approach, as well as its applicability to archived clinical specimens stored for up to 35 years...
