Importance: Pancreatic mucinous cystic neoplasms (MCNs) harbor malignant potential, and current guidelines recommend resection. However, data are limited on preoperative risk factors for malignancy (adenocarcinoma or high-grade dysplasia) occurring in the setting of an MCN. Objectives: To examine the preoperative risk factors for malignancy in resected MCNs and to assess outcomes of MCN-associated adenocarcinoma. Design, Setting, and Participants: Patients who underwent pancreatic resection of MCNs at the 8 academic centers of the Central Pancreas Consortium from January 1, 2000, through December 31, 2014, were retrospectively identified...

INTRODUCTION: In a distal pancreatectomy combined with a distal gastrectomy, the splenic artery and vein must be conserved. However, it is not easy in pure laparoscopic surgery. We performed a hand-assisted laparoscopic spleen-preserving distal pancreatectomy (HALS-SPDP) combined with a laparoscopic distal gastrectomy (LDG) for the treatment of a pancreatic neuroendocrine tumor (NET) with early gastric cancer. PRESENTATION OF CASE: A 67-year-old male was hospitalized with no complaint...

Pancreatic cancer is a highly lethal malignancy which tends to present with late stage disease. To date, identification of oncogenic drivers and aberrations has not led to effective targeted therapy. Approximately 5-15% of pancreatic cancer has an inheritable component. In fact, pancreatic adenocarcinoma is now recognized as a BRCA1/2-related cancer. Germline BRCA1/2 mutations can be found in up to 3.6-7% of unselected pancreatic cancer patients although the rates are significantly higher amongst patients with Ashkenazi Jewish ancestry...

BACKGROUND: Although serum carbohydrate antigen 19-9 (CA19-9), s-pancreas antigen-1 (SPan-1), and duke pancreatic monoclonal antigen type 2 (DUPAN-II) are commonly utilized tumor markers in pancreatic ductal adenocarcinoma (PDAC), it is still unclear which is the most useful for predicting prognosis after surgical resection. Here, we aimed to compare the prognostic impact of pre- and post-operative serum CA19-9, SPan-1, and DUPAN-II levels in patients with resectable PDAC. METHODS: Pre-operative CA19-9, SPan-1, and DUPAN-II levels were analyzed to compare their prognostic values for resectable PDAC in 198 patients whose pre-operative tumor markers were available...

OBJECTIVE: A history of periodontal disease and the presence of circulating antibodies to selected oral pathogens have been associated with increased risk of pancreatic cancer; however, direct relationships of oral microbes with pancreatic cancer have not been evaluated in prospective studies. We examine the relationship of oral microbiota with subsequent risk of pancreatic cancer in a large nested case-control study. DESIGN: We selected 361 incident adenocarcinoma of pancreas and 371 matched controls from two prospective cohort studies, the American Cancer Society Cancer Prevention Study II and the National Cancer Institute Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial...

BACKGROUND: Pancreatic ductal adenocarcinoma is a highly aggressive disease with 5-year overall survival not exceeding 5%. In the Czech Republic, the incidence of this tumor has been increasing; according to recent statistics, the Czech Republic is already number one worldwide in the occurrence of this malignancy. Delayed diagnosis due to asymptomatic course of the disease in the early stages is characteristic for this disease. AIM: The objective of this article is to give an overview of the most important factors, which according to current knowledge of pancreatic adenocarcinoma have a prognostic and predictive potential...

Importance: Patients with periampullary adenocarcinomas have widely variable survival. These cancers are traditionally categorized by their anatomic location of origin, namely, the duodenum, ampulla, distal common bile duct (CBD), or head of the pancreas. However, they can be alternatively subdivided histopathologically into intestinal or pancreaticobiliary (PB) types, which may more accurately estimate prognosis. Objectives: To identify factors associated with survival in patients with periampullary adenocarcinomas and to compare survival between those having intestinal-type or PB-type cancers originating from the duodenum, ampulla, or distal CBD with those having pancreatic ductal adenocarcinoma (PDAC)...

PURPOSE: The relationship between tumor metabolism and stage, subcutaneous and visceral fat thickness, and their glucose metabolism and overall survival in patients recently diagnosed with pancreatic carcinoma was assessed. METHODS: Thirty-eight consecutive patients were studied. Subcutaneous fat thickness (SFT), visceral fat thickness (VFT), and their corresponding FDG SUVmean, as well as SUVmean and SUVmax values of the primary tumor (PT) were derived from FDG-PET CT imaging...

INTRODUCTION: In pancreatic ductal adenocarcinoma (PDA), surgical resection is the only curative treatment, but due to its late clinical presentation only 15-25% patients are candidates for curative resection. The aim of this prospective, single-center study is to determine the diagnostic utility of preoperative PET-CT for early detection of PDA and early panIN lesions. METHODS: We studied the histopathological features of PDA and different panIN lesions in 139 surgical samples from patients undergoing pancreatic resection (from 2010-2014), comparing these results with preoperative PET-CT and MDCT study...

Pancreatic ductal adenocarcinoma (PDAC) ranks fourth among cancer-related deaths. The nucleoside analog gemcitabine has been the cornerstone of adjuvant chemotherapy in PDAC for decades. However, gemcitabine resistance develops within weeks of chemotherapy initiation, which might be intrinsic to cancer cells and influenced by tumor microenvironment. Recently, pancreatic stellate cells (PSCs) have greatly increased our attention on tumor microenvironment-mediated drug resistance. Periostin is exclusively overexpressed in PSCs and the stroma of PDAC creating a tumor-supportive microenvironment in the pancreas...
