Pancreatic adenocarcinoma may account for more than 80% of all pancreatic neoplasms. Occasionally, other rare tumors such as lymphoma, metastatic tumor, and solid pseudopapillary neoplasm can be considered in the differential diagnosis. We report the case of an 82-year-old man with a pancreatic solid mass. This case suggests that endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) w...
CONTEXT EUS with fine-needle aspiration and cyst fluid analysis is routinely used to evaluate pancreatic cysts; however, the clinical course of these lesions is often not well defined. OBJECTIVE Our study evaluated whether EUS imaging, cyst fluid CEA, and cytology combined with cyst fluid genetic analyses for allelic imbalance and genetic mutations can be used to better predict the malignant ...
PURPOSE Hemostatic activation is common in pancreatic cancer and may be linked to angiogenesis and venous thromboembolism. We investigated expression of tissue factor (TF), the prime initiator of coagulation, in noninvasive and invasive pancreatic neoplasia. We correlated TF expression with vascular endothelial growth factor (VEGF) expression, microvessel density, and venous thromboembolism in ...
A subset of pancreatic cystic neoplasms are regarded as precursor lesions of pancreatic cancer, but only a minority of all pancreatic cystic neoplasms will undergo malignant transformation. MicroRNAs are increasingly recognized as molecular targets in carcinogenesis. Previously, a 9-microRNA (miR) signature was suggested to discriminate between high risk and low risk pancreatic cystic neoplasm....
