The present study compared the efficacy of ultrasound elastography (UE), magnetic resonance imaging (MRI) and the combination of the two methods (UE+MRI) in the differential diagnosis of benign and malignant breast tumors. In total, 86 patients with breast masses were recruited and evaluated by UE, MRI and UE+MRI. Strain ratios of UE were calculated for the breast mass and adjacent normal tissues. In addition, the receiver operating characteristic (ROC) curve was obtained, while the sensitivity and specificity were calculated to determine the optimal cut-off point for the differential diagnosis...

The accuracy of next-generation sequencing (NGS) for detecting tumor-specific mutations in plasma DNA is hindered by errors introduced during PCR/sequencing, base substitutions caused by DNA damage, and pre-existing mutations in normal cells that are present at a low frequency. Here, we performed NGS of genes related to pancreatic cancer (comprising 2.8 kb of genomic DNA) in plasma DNA (average 4.5 ng) using molecular barcodes. The average number of sequenced molecules was 900, and the sequencing depth per molecule was 100 or more...

RATIONALE: Intraductal papillary mucinous neoplasms of the pancreas (IPMNs) are benign cystic tumors with a relevant risk of malignant transformation over time. Currently, follow-up after surgical resection of benign IPMNs remains controversial. PATIENT CONCERNS: This is a case report of a 68-year-old male who underwent pancreatic head resection for a multicystic side-branch IPMN with low-grade epithelial dysplasia in March 2009 at the Katharinenhospital Stuttgart, Germany...

A previously healthy 52-year-old man was referred to our hospital for further evaluation of main pancreatic duct dilatation. The preoperative work-up was consistent with intraductal papillary mucinous carcinoma (IPMC) derived from a mixed type intraductal papillary mucinous neoplasm (IPMN), because multilocular cysts with enhancing thickened pancreatic head walls and dilated pancreatic ducts lined with dysplastic mucinous epithelium, with papillary proliferation from the pancreatic body to the tail, were observed; in addition, the pancreatic juice cytology was class V, which is suggestive of adenocarcinoma...

The incidence of intraductal papillary mucinous neoplasms (IPMNs) has been increasing over the past decade, mainly owing to increased awareness and the increased use of cross-sectional imaging. The Sendai and Fukuoka consensus guidelines provide us with clinical management guidelines and algorithms; however, the clinical management of IPMNs continues to be challenging. Our incomplete understanding of the natural history of the disease, and the events and pathways that permit progression to adenocarcinoma, result in difficulties predicting which tumors are high risk and will progress to invasive disease...

BACKGROUND: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas comprise a heterogeneous group of intraductal mucin-producing neoplasms representing a typical adenoma-to-carcinoma sequence. The involvement of the main pancreatic duct (MPD) is a feature of paramount importance, directly related to a more aggressive biology and a higher malignancy rate. METHOD: We review and discuss the clinical management of IPMNs with a MPD involvement, recalling the different consensus guidelines and addressing recent controversies in literature, presenting the current clinical practice in Verona Pancreas Institute...

Microcystic, elongated, and fragmented (MELF) glandular features are associated with epithelial-mesenchymal transition, invasion, and progression in endometrioid adenocarcinoma of the uterus. Similar histological features are also observed at the periphery of pancreatic intraductal papillary mucinous neoplasms (IPMNs). However, the clinicopathological significance of MELF-like features-particularly whether they represent regenerative or truly neoplastic conditions-in IPMNs remains unclear. We assessed a total of 152 surgically resected IPMNs...

OBJECTIVES: Reprimo gene is a cytoplasmic protein belonging to a family of molecules controlled by p53 that inhibits cell cycle progression. Ectopic expression of Reprimo results in cell cycle arrest at the G2 phase. The aim of this study was to investigate the impact of Reprimo expression on tumorigenesis of intraductal papillary mucinous neoplasm (IPMN). METHODS: Thirty-seven surgical cases of IPMN were collected retrospectively. Twenty-eight patients had benign IPMNs (low-grade dysplasia, n = 18; intermediate-grade dysplasia, n = 10), and the remaining 9 had malignant IPMNs (high-grade dysplasia, n = 4; invasive carcinoma, n = 5)...

A 60-year-old man was admitted for a liver mass(S3), which rapidly increased in size during intraductal papillary mucinous neoplasm(IPMN)follow-up. Although EOB-MRIwas performed, the mass could not be accurately diagnosed as hepatic cancer. Thus, we performed a lateral segmentectomy. In the resected specimen, a solid tumor mass was clearly bound in segment 3 of the liver. Since histopathology revealed no malignant cells and many IgG4-positive cells, we confirmed the diagnosis as IgG4-related inflammatory pseudotumor of the liver...

The classification of histological phenotypes was originally conceived for pancreatic intraductal papillary mucinous neoplasms. Recently, it has been introduced for extrahepatic cholangiocarcinoma. The aim of the present study was to clarify the associations between histological phenotype and clinicopathological features of extrahepatic cholangiocarcinoma, using 99 cases of surgically-resected extrahepatic cholangiocarcinoma. All cases were divided into one of two histological phenotypes: Biliary-type (BT; 56 cases, 56...

A 68-year-old woman was referred to our hospital for the treatment of bile duct stone, pancreatic tumor, and pancreatic cysts. First, bile duct stone was removed using endoscopic retrograde cholangiopancreatography. By abdominal contrast-enhanced computed tomography, a 12-mm diameter tumor was found in the pancreatic body. The tumor was isodense compared with the surrounding pancreatic parenchyma in the non-contrast phase and poorly enhanced in the arterial phase; it exhibited gradual enhancement from the portal vein phase to the late phase...

Mass forming chronic pancreatitis is very rare. Diagnosis could be done by the pathologic findings of focal inflammatory fibrosis without evidence of tumor in pancreas. A 34-year-old man presented with right upper abdominal pain for a few weeks and slightly elevated bilirubin level on clinical findings. Radiological findings of multidetector-row computed tomography, magnetic resonance (MR) imaging with MR cholangiopancreatography and endoscopic ultrasonography revealed focal branch pancreatic duct dilatation with surrounding delayed enhancing solid component at uncinate process and head of pancreas, suggesting branch duct type intraductal papillary mucinous neoplasm...

BACKGROUND: Exosomes are nanovesicles that have been shown to mediate carcinogenesis in pancreatic ductal adenocarcinoma (PDAC). Given the direct communication of pancreatic duct fluid with the tumor and its relative accessibility, we aimed to determine the feasibility of isolating and characterizing exosomes from pancreatic duct fluid. METHODS: Pancreatic duct fluid was collected from 26 patients with PDAC (n = 13), intraductal papillary mucinous neoplasm (IPMN) (n = 8) and other benign pancreatic diseases (n = 5) at resection...

The patients of pancreatic cystic neoplasms diagnosed and treated are increasing over the past decade. Recent and long-tern risk and benefit should be well balanced when considering treatment, follow the principle of patient-benefit. For low malignancy potential neoplasm like serous cystic tumor or branch duct intraductal papillary mucinous neoplasm, surgical indication should be reserved to those with obvious malignant potential.Decreasing perioperative mortality and morbidity should be emphasized. Comprehensive studies are needed to validate the efficacy of new diagnostic and treatment technique before applied to clinical...

Pancreatic cancer (PC) is the seventh most common cause of cancer-related deaths worldwide that kills more than 300,000 people every year. Prognosis of PC is very poor with a five-year survival rate about 5%. The most common and highly observed type of PC is pancreatic ductal adenocarcinoma (PDAC). It is preceded by the progression of precursor lesions such as Pancreatic Intraepithelial Neoplasia (PanIN), Intraductal Papillary Neoplasm (IPMN) and Mucinous Cystic Neoplasm (MCN). PanIN is the most common among these premalignant lesions...
