• Are There Early Signs of Pancreatic Cancer?

Are There Early Signs of Pancreatic Cancer?

Changes in blood glucose and lipid levels occur up to 18 months before a diagnosis of pancreatic cancer, researchers report in the May issue of Gastroenterology. These changes might be used in combination with other risk factors to detect pancreatic cancer at earlier stages. One reason for the high mortality

  • REVIEW: Combining CRISPR-Cas9 and Organoid Technologies to Study Gastrointestinal Diseases

REVIEW: Combining CRISPR-Cas9 and Organoid Technologies to Study Gastrointestinal Diseases

CRISPR-Cas9 technology can be used to engineer organoids for studies of gastrointestinal development and disease pathogenesis. In the February issue of Gastroenterology, Masayuki Fujii et al review derivation of organoids from human gastrointestinal tissues and how CRISPR-Cas9 has advanced studies of the digestive system. CRISPR-Cas9 genome editing technology allows researchers to

  • How Does Cigarette Smoke Promote Pancreatic Tumor Development?

How Does Cigarette Smoke Promote Pancreatic Tumor Development?

Exposure to cigarette smoke activates stem cell features in pancreatic cells, via nicotinic cholinergic receptor signaling to transcription factors that activate expression of stem cell genes, researchers report in the September issue of Gastroenterology. Levels of the stem cell transcriptional regulator PAF1 are increased in pancreatic tumors from humans and

  • Hyperglycemia as a Marker for Early Detection of Pancreatic Cancer

Hyperglycemia as a Marker for Early Detection of Pancreatic Cancer

Patients are hyperglycemic for a mean period of 36 to 30 months before a diagnosis of pancreatic ductal adenocarcinoma (PDAC), researchers report in the August issue of Gastroenterology. This information might be used in strategies for early detection. At the time of PDAC diagnosis, approximately 85% of subjects have hyperglycemia

  • Does Acute Pancreatitis Increase Risk of Pancreatic Cancer?

Does Acute Pancreatitis Increase Risk of Pancreatic Cancer?

Patients hospitalized with acute pancreatitis have a 2-fold increased risk of pancreatic cancer compared with the general population, researchers report in the May issue of Gastroenterology. Acute pancreatitis is a sudden-onset inflammatory disease of the pancreas. Although acute pancreatitis promotes development of pancreatic cancer in mouse models, there have been conflicting findings from epidemiology

  • Review: How Does the Tumor Stroma Contribute to Pancreatic Cancer Progression, and Can We Stop It?

Review: How Does the Tumor Stroma Contribute to Pancreatic Cancer Progression, and Can We Stop It?

Recently developed approaches for reshaping the pancreatic tumor stroma might be used in treatments for pancreatic cancer, according to a review in the March issue of Gastroenterology. The authors discuss relationships among the pancreatic tumor extracellular matrix, the vasculature, the immune system, and metabolism, and how these might be manipulated to stop pancreatic tumor

  • VIDEO: Non-invasive Detection of Early- and Late-Stage PDAC

VIDEO: Non-invasive Detection of Early- and Late-Stage PDAC

Specific patterns of volatile organic compounds (VOCs) in urine samples can identify patients with pancreatic ductal adenocarcinoma (PDAC), researchers report in the February issue of Gastroenterology. The noninvasive technology, based on ion mobility spectrometry, can be used to discriminate between healthy individuals vs individuals with early- or advanced-stage cancer. VOCs are metabolic products of microbes that can

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

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.
