    Numerous drugs can damage the gastrointestinal tract, and improved recognition of drug-induced gastrointestinal tract pathology is needed to improve patient care. The authors of this Review discuss the most common and well-described drug-related clinicopathological conditions of the gastrointestinal tract. Much discussion is dedicated to NSAIDs—the most commonly prescribed drugs and consequently the drugs most commonly associated with gastrointestinal tract toxicity.

    Pancreatic stellate cells are the main mediator of fibrogenesis during chronic pancreatitis, and chronic pancreatitis is a consistent risk factor for pancreatic ductal adenocarcinoma. In this Review, the authors discuss the idea that pancreatic stellate cells have a linking role in the development of pancreatic ductal adenocarcinoma via their ability to communicate with inflammatory cells, acinar cells and pancreatic cancer cells.
