Core Tip

Core Tip: Pancreatic tumors had different clinicopathological characteristics by anatomic location in the pancreas. We first investigated the different outcomes and characteristics between mucinous adenocarcinoma in the pancreatic head and body/tail using a variety of analytical methods. In conclusion, adenocarcinoma located at the pancreatic head tended to be characterized by longer survival and more favorable characteristics.
