Intraductal papillary mucinous neoplasms (IPMNs) are deadly exocrine mucinous tumors. Currently the molecular features and diagnostic markers of IPMNs are not well understood. In this study, we performed microRNA (miRNA) profiling assays to study the potential roles of miRNAs in IPMNs using 78 cases of IPMN patients and controls. When comparing the miRNA expression between IPMN patient samples and controls, we found that miR-210, miR-223, miR-221, miR-155 and miR-187 were differentially expressed in normal pancreas and IPMNs...

Malignant neoplasms represent the second most common cause of death in men and women in the Czech Republic after cardiovascular diseases. The incidence, prevalence and mortality is recorded in the Czech National Cancer Registry. The most recent data available is from 2013, in this year there were 81 541 patients newly diagnosed with cancer and 26 944 people died of cancer. From a long-term perspective, the incidence of neoplasms is increasing and the mortality is decreasing. In the Institute of Forensic Medicine in Brno there were 480 cases of newly reported malignant tumors during the period 2010-2015, which were not known before the autopsy...

PURPOSE: Recently, cholangioscopy using narrow band imaging (NBI) has been used as a diagnostic modality for better visualization in hepatobiliary malignancies; however, there are few reports on it. Our aim is to evaluate the effectiveness of cholangioscopy using NBI in hepatobiliary malignancies. METHODS: Between January 2007 and December 2016, 152 cholangioscopies using percutaneous approach were conducted in total 123 patients. Among these, 36 patients were suspicious of hepatobiliary malignancies...

The diffuse neuroendocrine system continues to be an enigmatic topic of study in pathology due to its controversial embryologic origins, biology and a variety of tumors engendered. Originally thought to be localized to the classic neuroendocrine organs (pituitary, thyroid, pancreas and adrenal medulla), the neuroendocrine cells are now known to be distributed in every organ system of the body. A number of human diseases have been linked to aberrations in the functioning of the neuroendocrine cells. Neoplasms of the neuroendocrine system can thus occur in myriad primary sites and range in behavior from benign to lethal...

RATIONALE: Pancreatic acinar cell carcinoma (ACC) is a rare malignant tumor of exocrine pancreas. It is typically a well-marginated large solid mass arising in a certain aspect of the pancreas. Diffuse involvement of ACC in the pancreas is very rare, and may simulate pancreatitis in radiological findings. We report 2 cases of ACC presenting as diffuse enlargement of the pancreas due to tumor involvement without formation of a distinct mass. PATIENT CONCERNS: The patients consisted of a 41-year-old man with weight loss and a 77-year-old man who was asymptomatic...

Background/Aims: Recent studies have revealed that contrast-enhanced harmonic endoscopic ultrasonography (CEH-EUS) is beneficial in the differential diagnosis of malignant neoplasms of the pancreas and gallbladder from benign masses, in terms of the evaluation of microvasculature and real-time perfusion. In this study, we aimed to prove the clinical value of CEH-EUS in the differential diagnosis of pancreatic and gallbladder masses by direct comparison with that of conventional EUS. Methods: We reviewed the sonographic images and medical information of 471 patients who underwent conventional EUS and CEH-EUS for the diagnosis of pancreatic and gallbladder masses at a single medical center (Severance Hospital, Seoul, Korea) between March 2010 and March 2016...

A 56-year-old man presented with a chest computed tomography (CT) finding of a right upper lobe nodule, which was diagnosed using brush cytology as adenocarcinoma stage IB (cT2aN0M0). Repeat CT scan for preoperative evaluation revealed a small, slightly hypodense spot in the pancreatic body, which was diagnosed as pancreatic metastasis from lung cancer using endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB). Because of the presence of distant metastasis, surgical resection was deferred and chemotherapy was chosen instead...

BACKGROUND: Medullary thyroid carcinoma (MTC) is a rare disease. Treatment options for recurrent disease are limited. Somatostatin analogues might have a role as anticancer agents agents in MTC, although the evidence is inconclusive. PATIENT FINDINGS: A 64-year old male was diagnosed with MTC in January 2010. Total thyroidectomy with neck dissection (stage IVA, pT2pN1bM0, R1) was performed, followed by adjuvant locoregional radiotherapy. Two years later, the patient developed recurrent metastatic disease evidenced by elevated carcinoembryonic antigen (CEA) and calcitonin levels, and a positive uptake (Octreoscan®) in the right adrenal gland and pancreatic head...

MEN1-associated pancreatic neuroendocrine tumors (pNETs) may potentially express distinct hormones, but the mechanism has not been elucidated. Transcription factors such as MafA and Pdx1 have been identified to lead to beta cell differentiation, while Arx and Brn4 to alpha cell differentiation in developing pancreas. We hypothesized those transcription factors are important to produce specific hormones in pNETs, similarly to developing pancreas, and examined the expression of transcription factors in a case of MEN1 who showed immunohistological coexistence of several hormone-producing pNETs including insulinoma...

Remarkably, majority of the cancer deaths are due to metastasis, not because of primary tumors. Metastasis is one of the important hallmarks of cancer. During metastasis invasion of primary tumor cells from the site of origin to a new organ occurs. Metastasis associated proteins (MTAs) are a small family of transcriptional coregulators that are closely associated with tumor metastasis. These proteins are integral components of nuclear remodeling and deacetylation complex (NuRD). By virtue of being integral components of NuRD, these proteins regulate the gene expression by altering the epigenetic changes such as acetylation and methylation on the target gene chromatin...

Pancreatic ductal adenocarcinoma (PDAC) is a very aggressive tumor with a five-year survival of less than 6%. Chronic pancreatitis (CP), an inflammatory process in of the pancreas, is a strong risk factor for PDAC. Several genetic polymorphisms have been discovered as susceptibility loci for both CP and PDAC. Since CP and PDAC share consistent number of epidemiologic risk factors, the aim of this study was to investigate whether specific CP risk loci also contribute to PDAC susceptibility. We selected five common SNPs (rs11988997, rs379742, rs10273639 rs2995271 and rs12688220) that were identified as susceptibility markers for CP and analyzed them in 2,914 PDAC cases, 356 CP cases and 5,596 controls retrospectively collected in the context of the international PANDoRA consortium...

Carcinosarcomas are rare biphasic neoplasms with distinct malignant epithelial and mesenchymal components. Most commonly, carcinosarcomas arise in the uterus as malignant mixed müllerian tumors, but also infrequently appear in other organs such as the ovaries and breast, the prostate and urinary tract, the lungs, or in the gastrointestinal system, among others. Pancreatic carcinosarcomas are exceedingly rare; only a few cases are reported in the English literature. Their pathogenesis remains to be fully clarified...

Multiple endocrine neoplasia type 1 and 2 are hereditary cancer syndromes. They are characterized by the occurrence of many benign and malignant tumor types, in MEN1 parathyroid tumors, pituitary tumors, and pancreas tumors, in MEN2 medullary thyroid carcinoma, pheochromocytoma, and parathyroid tumors. The autosomal dominant inherited tumor syndromes are caused by mutations in the MEN1 gene, a tumor suppressor gene, and mutations in the RET gene, an activated oncogene, in MEN2. The clinical expression of the different tumors can vary within and between families, with a good genotype-phenotype correlation in MEN2...

Solid pseudopapillary neoplasm of the pancreas is one of the rarest forms of pancreatic neoplasm. It was also known as Franz's tumor or Hamoudi tumor until WHO labeled it as solid pseudopapillary tumor (SPT) in 1996. It typically affects young non-Caucasian females in their second or third decade of life. Treatment involves complete excision of the tumor which results in complete cure in majority of the cases. We present here a report of 11-year-old girl with SPT and also do a review of literature for this rare tumor...

Interferon regulatory factor 6 ( IRF6) acts as a tumor suppressor and controls cell differentiation in ectodermal and craniofacial tissues by regulating expression of target genes. Haploinsufficiency of IRF6 causes Van der Woude and popliteal pterygium syndrome, 2 syndromic forms of cleft lip and palate. Around 85% of patients with Van der Woude express pits on the lower lip that continuously or intermittently drain saliva, and patients with the common cleft lip and palate have a higher prevalence of dental caries and gingivitis...
