Exocrine and endocrine malignancies of the pancreas

1. Big picture

Pancreatic malignancies are divided into two major groups:

1. Exocrine pancreatic malignancies Mostly pancreatic ductal adenocarcinoma, the classic “pancreatic cancer.” It is aggressive, often diagnosed late, and surgery is possible only in a minority of patients.

2. Endocrine pancreatic malignancies Pancreatic neuroendocrine tumours, also called pancreatic NETs or islet cell tumours. They may be functional and produce hormones, or non-functional and present as a mass/metastasis.

The surgical exam question is:
