Brief description

This is a primary malignant neoplasm of the exocrine pancreas. The SOP does not cover benign neoplasms or secondary neoplasms arising from other sources.

The pancreas is composed of: exocrine glands which supply enzymes to the gastrointestinal tract via the pancreatic ducts; and, islands (islets) of endocrine tissue scattered through the pancreas, which secrete hormones (insulin, glucagon, somatostatin) into the blood stream. This SOP only applies to a cancer of the exocrine tissue and not the endocrine tissue.

The diagnostic label should refer to the part of the pancreas affected by the neoplasm, being the head, body or tail of the pancreas.

Confirming the diagnosis

This diagnosis requires histological confirmation from a biopsy or surgical resection of pancreatic tissue. A range of other tests and imaging may be performed.

The relevant medical specialist is a gastroenterologist, general surgeon or oncologist.

# non-SOP condition

Clinical onset

The condition most commonly presents clinically, with symptoms of pain (abdominal or epigastric), jaundice, and weight loss.  A range of other non-specific symptoms may also occur.  Pain is usually of insidious onset and has been present for some time at the time of first presentation.  The condition is occassionally first uncovered as an incidental finding on CT or MRI scan.

Clinical worsening

The only SOP worsening factor is for inability to obtain appropriate clinical management.  The condition often presents late and has a poor prognosis.  Surgical resection is not possible in most cases.
