Researchers find potential new target against colorectal cancer
Jul. 21, 2022—by Bill Snyder Researchers at Vanderbilt University Medical Center have discovered a potential new target in the fight against colorectal cancer, the nation’s third most common malignancy and, next to lung cancer, the second leading cancer killer. This month in the journal Gastroenterology, R. Daniel Beauchamp, MD, Anna Means, PhD, and colleagues report that a...
Difficulty swallowing linked to chronic opioid use: study
Jul. 21, 2022—Vanderbilt researchers found that chronic use of opioid painkillers like hydrocodone and oxycodone significantly increases the risk of dysphagia, or difficulty swallowing.
Study reveals how gastric cancer forms, suggests preventive treatment
Jun. 23, 2022—Eunyoung Choi, PhD, assistant professor of Surgery, and colleagues identified for the first time that Trop2+/CD133+/CD166+ dysplastic stem cells are a key source of clonal evolution of dysplasia to multiple types of gastric cancer.
Study finds genetic factor undermines H. pylori treatment
Aug. 4, 2021—Helicobacter pylori, a stomach-dwelling bacterium, is a strong risk factor for gastric cancer, peptic ulcers and other debilitating gastrointestinal disorders. Yet efforts to eradicate it using a combination of antibiotics and proton pump inhibitors (PPIs), which suppress gastric acid production, often fail.
