While surgery currently remains the only potentially curative treatment available for pancreatic cancer, only 20% to 30% of patients have resectable disease at diagnosis. Recently, with the introduction of intensive chemotherapy regimens such as oxaliplatin, irinotecan, fluorouracil plus leucovorin (FOLFIRINOX) and gemcitabine plus nab-paclitaxel, for the treatment of unresectable pancreatic cancer, the antitumor activity and overall survival in patients with pancreatic cancer have dramatically improved. These advances in intensive chemotherapy have led to the possibility of conversion of unresectable disease to resectable disease, and it has been reported that more than 20% of pancreatic cancer patients with unresectable locally advanced disease at diagnosis undergo successful conversion surgery after FOLFIRINOX therapy...

Pancreatic ductal adenocarcinoma (PDAC) is a particularly deadly disease. Chronic conditions, including obesity and type-2 diabetes are risk factors, thus making PDAC amenable to preventive strategies. We aimed to characterize the chemo-preventive effects of metformin, a widely used anti-diabetic drug, on PDAC development using the KrasG12D mouse model subjected to a diet high in fats and calories (HFCD). LSL-KrasG12D/+ ;p48-Cre (KC) mice were given control diet (CD), HFCD, or HFCD with 5 mg/ml metformin in drinking water for 3 or 9 months...

Curative resection is necessary to survival in pancreatic cancer, however after surgery, pathologic examination sometimes diagnoses the remains of cancer at the resected stump. Therefore, it is necessary to evaluate the stump by intraoperative rapid pathological examination. 5-aminolevulinic acid(5-ALA)is an endogenous natural amino acid and precursor of the heme pathway. 5-ALA is metabolized and accumulated as protoporphyrin IX(Pp IX)that is photosensitive substance. 5-ALA mediated photodynamic diagnosis(PDD)(ALA-PDD)has high diagnostic ability...

A 74-year-old man was referred to our hospital for further investigation of a cystic lesion in the pancreatic body, which had been detected by ultrasonography at a local hospital. He was diagnosed as intraductal papillary mucinous neoplasm(IPMN) and further preoperative examinations were conducted. Upper gastrointestinal endoscopy demonstrated a type 0-II c tumor of the greater curvature in the upper third of the stomach. Endoscopic ultrasonography showed no sign of submucosal invasion. Endoscopic submucosal dissection(ESD)was carried out and pathological examination of a specimen revealed well differentiated adenocarcinoma with submucosal invasion, which fulfilled the indication for additional gastrectomy with lymph node dissection...

A 70's man underwent subtotal stomach preserving pancreatoduodenectomy(SSPPD)for pancreatic head cancer. The pathological diagnosis was adenosquamous carcinoma(ASC)of the pancreas. Two months after surgery, a recurrent tumor in the remnant pancreas was confirmed with a CT scan and suspected to be ASC by endoscopic ultrasound-guided fine needle aspiration(EUS-FNA). As the recurrent lesion was limited in the pancreas, total remnant pancreatectomy(TP)was performed 4 months after SSPPD. The final pathological diagnosis was ASC...

There is a clear consensus regarding the combined resection of organs with cancer invasion, patients with colon cancer. However, there are very few reports to our knowledge regarding the use of pancreato-duodenectomy(PD)for colon cancer patients with cancer invasion in the duodenum. We here report a colon cancer patient in whom we performed PD and right hemicolectomy, who showed favorable results with no recurrence. The patient was a 69-year-old woman. Her chief complaint was hypogastric pain. Her previous doctor performed colonoscopy and a colonoscopic biopsy, and detected a type 2 lesion, throughout the entire circumference of the transverse colon near the liver, and she was diagnosed with adenocarcinoma...

A polysaccharide with a molecular weight of 13,029 Da was isolated from Momordica charantia (MCP) fruit and purified by ion-exchange and size-exclusion chromatography. The isolated polysaccharide MCPIIa contained L-Rha, D-GalA, D-Gal, D-Xyl, L-Ara in a molar ratio of 12:3.05:19.89:5.95:56. IR spectrum and NMR studies indicated that the MCPIIa sugar units were linked, via β-glycosidic bonds, to a large number of arabinofuranose, glucuronic acid, and xylopyranosyl residues. In addition, the hypoglycemic effect of MCPIIa was investigated in streptozotocin (STZ)-induced diabetic mice...

Pancreatic incidentalomas are increasingly recognized entities that occur as a fallout of widespread availability of high definition imaging technology. These lesions offer diagnostic dilemmas to both clinicians and radiologists alike. Nevertheless, it is the advancement in diagnostic radiology that comes to the rescue in the management of these not-so-uncommon lesions.

Neuroendocrine tumors of the pancreas (pNETs) are a rare group of neoplasms that originate from the endocrine portion of the pancreas. Tumors that either secrete or do not secrete compounds, resulting in symptoms, can be classified as functioning and non-functioning pNETs, respectively. The prevalence of such tumors has recently increased due to the use of more sensitive imaging techniques, such as multidetector computed tomography, magnetic resonance imaging and endoscopic ultrasound. The biological behavior of pNETs varies widely from indolent, well-differentiated tumors to those that are far more aggressive...

Pancreatic and gastric heterotopia is an uncommon congenital anomaly in which gastric and/or pancreatic tissue is found outside of its anatomic location. In the majority of patients, lesions are found incidentally because they tend to be asymptomatic. However, lesions may become symptomatic when inflammation, obstruction, and bleeding occurs. Depending on tissue size and location they can harvest a landscape of nonspecific symptoms, causing a delay in diagnosis. Heterotopic tissue of either gastric or pancreatic origin have been reported in literature, however the presence of combined gastric and pancreatic heterotopic tissue is exceedingly rare...

Background and Objectives: EUS guided core biopsy was once rarely performed but is now entering mainstream practice. Neuroendocrine tumors often warrant core biopsy as sufficient tissue must be obtained to allow for special staining to ensure a correct diagnosis. Traditionally these lesions were sampled with FNA needles. We performed a retrospective pilot study to evaluate the clinical value and efficacy of the a new EUS core needle biopsy needle as compared to a standard EUS FNA needle in the evaluation of patients with known or suspected neuroendocrine tumors...

Simultaneous presence of pancreatic serous cystic neoplasms and neuroendocrine neoplasms is rare. We present a case with the incidental finding of a duodenal neuroendocrine tumor (NET) with 2 lymph node metastases in a Whipple resection specimen performed to remove a pancreatic cystic neoplasm that postoperatively turned out to represent a serous cystic neoplasm (SCN). The patient was a 75-year-old female. She presented with loss of appetite and weight. Preoperative contrast-enhanced computed tomography scan of the abdomen showed a multicystic lesion in the head of pancreas...

Adenomyoma and adenomyomatous hyperplasia are benign tumor-like lesions that rarely involve the major or minor duodenal papilla. We report the case of a 73-year-old patient who underwent a cephalic duodenopancreatectomy due to clinical and radiological evidence of underlying malignant neoplasm. The histopathology results revealed the unusual association of a major duodenal papilla adenomyoma and an adenomyomatous hyperplasia of the minor papilla. Because of their resemblance to pancreatic malignancy, the diagnosis of these lesions is particularly challenging...

AIMS: External beam radiotherapy (EBRT) is infrequently used to treat gastroenteropancreatic neuroendocrine tumours (GEPNETS), with little published data to date. We carried out a systematic review to assess the activity of EBRT for GEPNETS. MATERIALS AND METHODS: Major databases were searched for papers including at least five patients treated with contemporary EBRT techniques. Eligible studies underwent dual independent review. The primary end points were response rate for lesions treated with definitive intent and recurrence-free survival for primary lesions treated with neoadjuvant or adjuvant intent...

Pancreatic schwannomas are uncommon. About 60% of pancreatic schwannomas develop cystic lesions, and the differential diagnosis from other cystic pancreatic tumors is difficult. A 43-year-old man presented for evaluation of liver dysfunction detected during a medical checkup. Blood testing detected obstructive jaundice. A computed tomography scan revealed a well-defined polycystic tumor of about 5 cm at the pancreatic head. We performed surgical resection to treat the patient's symptoms and facilitate long-term management...

BACKGROUND: Since the 1860's hypercoagulability and malignancy have been linked. However, the impact of different neoplasms on multiple components of the coagulation system remains poorly understood. Thrombelastography (TEG) enables measurement of coagulation incorporating clotting through fibrinolysis. We hypothesize that specific TEG indices are associated with hypercoagulability can be appreciated in patients with adenocarcinoma undergoing pancreatic resection. STUDY DESIGN: Blood samples were obtained in patients undergoing pancreatic resection before surgical incision and assayed with TEG...
