Focal pancreatic parenchymal atrophy could be a precursor of pancreatic cancer.

Background/objectives: We previously reported that focal pancreatic parenchymal atrophy (FPPA) indicates high-grade pancreatic intraepithelial neoplasia (HG-PanIN) or carcinoma in situ (CIS). Because HG-PanIN progresses into pancreatic ductal adenocarcinoma (PDAC), the relationship between FPPA and PDAC should be investigated.

Methods: We included 54 patients with PDAC, whose previous computed tomography or magnetic resonance imaging were reviewed.

Analysis of Methylation of Tumor-suppressive miRNAs and Mutations in Pancreatic Juice.

Background/aim: We previously reported the usefulness of detecting aberrant methylation in tumor suppressive microRNAs (miRNAs) in bile and plasma to discriminate pancreaticobiliary cancers from benign pancreaticobiliary diseases. This study analyzed the methylation of miRNAs in pancreatic juice to identify those specific to pancreatic cancer (PC).

Patients And Methods: Pancreatic juice was collected from 20 patients with PC, including eight with intraductal papillary mucinous carcinoma (IPMC), two with low grade-pancreatic intraepithelial neoplasia (LG-PanIN), 32 with LG-intraductal papillary mucinous neoplasm (IPMN), and seven with benign pancreatic lesions.

Endoscopic Nasopancreatic Drainage Contributes to Early Resolution of Postgastrectomy Gastropancreatic Fistula.

A 76-year-old man experienced abdominal pain 43 days after gastric cancer resection. Computed tomography revealed a gastric wall defect extending to the pancreas, and endoscopic retrograde pancreatography revealed a gastropancreatic fistula. Afterward, a nasopancreatic duct drainage tube was inserted.

A Novel Diagnostic Imaging Method for the Early Detection of Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis, with a survival rate of less than 10% [...
