What is the Risk of Pancreatic Cancer in Patients with Low-Risk IPMNs?

Low-risk intraductal papillary mucinous neoplasms have an almost 8% chance of progressing to pancreatic cancer within 10 years, whereas higher-risk IPMNs have almost 25% chance, reports a systematic review and meta-analysis in the October issue of Clinical Gastroenterology and Hepatology. Continued long-term surveillance is therefore important for patients with low-risk, as

  • Hemosuccus Pancreaticus Caused by a Pancreatic Tumor

Hemosuccus Pancreaticus Caused by a Pancreatic Tumor

Researchers describe a rare cause of hemosuccus pancreaticus in a patient with pancreatic cancer. The gastrointestinal bleeding was caused by erosion of pancreatic adenocarcinoma into the colon, they show in the April issue of Clinical Gastroenterology and Hepatology. Hemosuccus pancreaticus is defined as hemorrhage from the ampulla of Vater via the pancreatic

  • Why do Pancreatic Tumor Cells Love the Liver?

Why do Pancreatic Tumor Cells Love the Liver?

Pancreatic ductal adenocarcinoma (PDAC) and its precursors secrete high levels of tissue inhibitor of metalloproteinases 1 (TIMP1) into the circulation, which activates hepatic stellate cells (HSCs) in liver. These cells help create a niche that promotes metastasis of pancreatic tumors to liver, researchers report in the November issue of Gastroenterology.

  • Finding Circulating Tumor Cells in Patients With Pancreaticobiliary Cancers

Finding Circulating Tumor Cells in Patients With Pancreaticobiliary Cancers

Circulating tumor cells (CTCs) can be isolated from portal venous blood collected during endoscopic ultrasound (EUS) of patients with pancreaticobiliary cancers, researchers report in the December issue of Gastroenterology. CTCs isolated from peripheral blood of patients with metastatic breast, colorectal, or prostate cancer can be analyzed to predict patient survival. However, blood samples from

  • How Does Smoking Lead to Pancreatic Cancer?

How Does Smoking Lead to Pancreatic Cancer?

Nicotine promotes pancreatic carcinogenesis by disrupting signaling and transcriptional pathways to cause dedifferentiation of acinar cells, researchers report in the November issue of Gastroenterology. One fourth of all deaths from pancreatic ductal adenocarcinoma (PDAC) are associated with tobacco use, and heavy smoking increases risk for PDAC 6-fold. Although smokers develop PDAC

How Can We Prevent Pancreatic Disease?

Tobacco use, obesity, and heavy use of alcohol are the factors most likely to increase risk for pancreatic diseases, researchers report in the October issue of Clinical Gastroenterology and Hepatology. Vegetables and fruit, on the other hand, appear to reduce risk. Strategies to prevent acute pancreatitis, chronic pancreatitis, and pancreatic

Can we Increase Detection of Duct Abnormalities by MRCP?

Administration of secretin improves noninvasive imaging of pancreatic duct abnormalities with higher levels of sensitivity than magnetic resonance cholangiopancreatography (MRCP), researchers report in the September issue of Gastroenterology. Pancreatic imaging is an essential element in evaluation of patients with abdominal pain or suspected pancreatitis. MRCP allows physicians to visualize fluid

  • Can a Vaccine Prevent Pancreatic Cancer Progression?

Can a Vaccine Prevent Pancreatic Cancer Progression?

Researchers have developed immunotherapy to slow progression of early-stage pancreatic tumors in mice. This approach might be developed to prevent progression of premalignant lesions to PDA, researchers report in the June issue of Gastroenterology. Pancreatic ductal adenocarcinoma (PDA) is a difficult cancer to treat because it is usually detected at

  • Cancer Cells in Circulation

Cancer Cells in Circulation

Pancreatic cancer cells can be detected in patients’ circulation before tumors are discovered, researchers report in the March issue of Gastroenterology. Cancer cells have long been believed to acquire metastatic potential after large primary tumors are established. However, many patients undergoing pancreatectomy for chronic pancreatitis are found to have disseminated pancreatic

How Does a High-Fat Diet Contribute to Pancreatic Cancer?

A high-fat diet can promote development of pancreatic cancer, but cyclooxygenase-2 (COX2) inhibitors prevent this process, according to a mouse study published in the December issue of Gastroenterology. The mechanisms appear to involve activation of oncogenic KRAS and upregulation of COX2, which promotes pancreatic inflammation. Increased body mass index and
