The signs of this rare bile-duct cancer typically go unnoticed at first. Here’s what to know.

A recent study has linked inflammation-driven carcinogenesis in the colon to loss of an important signaling protein called SMAD4.
Sirtex Medical Ltd. has renewed a grant award to Dan Brown, MD, professor of Radiology and Radiological Sciences and chief of Interventional Oncology, and his Vanderbilt Health colleagues, for a research program designed to treat patients with liver tumors that cannot be addressed with surgery.
Richard Peek, MD, director of the Vanderbilt Digestive Disease Research Center (VDDRC) and chief of the Division of Gastroenterology, Hepatology and Nutrition, has been appointed to serve on the advisory council of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
Calcium plays key roles in cellular signaling, proliferation and death. Previous studies exploring the relationship between dietary calcium intake and colorectal cancer have had contradictory results, perhaps due to no consideration of variation in calcium reabsorption by the kidney.
The targeted anti-cancer therapies cetuximab and panitumumab are mainstays of treatment for advanced colorectal cancer, the second leading cause of cancer-related deaths in the United States. However, many patients have tumors with genetic mutations that make them resistant to these anti-epidermal growth factor receptor (EGFR) monoclonal antibodies, or the cancers develop resistance during treatment.
In a study published in the journal Scientific Reports, Alexander Zaika, Ph.D. and coworkers show that DNA damage in the esophageal cells caused by acidic bile reflux (BA/A) activates enzymes called NADPH oxidases in the mitochondria, the cell’s power house, to release highly reactive-oxygen species (ROS).
Pancreatic ductal carcinoma (PDAC) is one of the most lethal types of cancer, with new therapeutic options needed. Sergey Novitskiy, M.D., Ph.D., and colleagues investigated the immune response during the development of aggressive PDAC in an animal model of the disease.
Dietary intake of polyunsaturated fatty acids (PUFAs) has been associated with risk of colorectal cancer, with omega-6 PUFAs increasing and omega-3 PUFAs decreasing risk. Most studies, however, have relied on questionnaires to assess consumption of fatty acids, and results have been inconsistent. Harvey Murff, M.D., and colleagues have studied a blood-based biomarker of PUFA intake. […]
Gastric cancer – a leading cause of cancer-related deaths worldwide – is commonly diagnosed at a late stage when most patients have a poor prognosis. Wael El-Rifai, M.D., Ph.D., and colleagues are exploring the molecular alterations that drive gastric carcinogenesis, to improve early detection, treatment and prevention. They previously showed that knocking out (eliminating) the […]
