Multiple Choice

Pancreatic ductal adenocarcinoma is most commonly located in which region of the pancreas, and what complication is it frequently associated with?

Pancreatic ductal adenocarcinoma most often arises in the head of the pancreas, and its proximity to the distal common bile duct means it commonly blocks bile flow. This leads to obstructive jaundice, a classic presenting feature when the tumor is in the head. Tumors in the body or tail tend to present differently, often with weight loss or abdominal pain, and are less likely to cause biliary obstruction. Islet cell tumors are a different, neuroendocrine category with distinct clinical patterns. So the combination of a head-location with biliary obstruction best fits the typical behavior of pancreatic ductal adenocarcinoma.
