Overview

Symptoms of pancreatic cancer include jaundice, light-colored stools or dark urine, pain in the upper/middle abdomen and back, weight loss, loss of appetite and fatigue.

History and Symptoms

• Pancreatic cancer symptoms depend on the site of the tumor within the pancreas and the degree of tumor involvement.
• In the early stages of pancreatic cancer there are not many noticeable symptoms. As the cancer grows, symptoms may include the following:

• Jaundice
• Light-colored stools or dark urine
• Pain in the upper or middle abdomen and back
• Unexplained weight loss
• Anorexia
• Fatigue

• Functional Pancreatic Neuroendocrine Tumors and their Characteristics are mentioned in the following table:

Functional Pancreatic Neuroendocrine Tumors and their Characteristics
Tumor type and syndrome	Location in pancreas	Signs and symptoms	Circulating biomarkers
Insulinoma (Whipple’s triad)	Head, body, tail (evenly distributed)	Hypoglycemia, dizziness, sweating, tachycardia, tremulousness, confusion, seizure	CgA and CgB, insulin inappropriate for blood glucose level, proinsulin, C-peptide
Gastrinoma (Zollinger–Ellison)	Gastrinoma triangle Often extrapancreatic (duodenal); can be found anywhere in gland	Gastric acid hypersecretion, peptic ulcer, diarrhea, esophagitis, epigastric pain	CgA, gastrin, PP (35%)
VIPoma (Verner– Morrison syndrome, WDHA)	Distal pancreas (body and tail) Often spread outside pancreas	Watery diarrhea, hypokalemia, achlorhydria (or acidosis)	CgA, VIP
Glucagonoma	Body and tail of pancreas Often large and spread outside pancreas	Diabetes (hyperglycemia), necrolytic migratory erythema, stomatitis, glossitis, angular cheilitis	CgA, glucagon, glycentin
Somatostatinoma	Pancreatoduodenal groove, ampullary, periampullary	Gallstones, diabetes (hyperglycemia), steatorrhea	CgA, somatostatin
Ppoma	Head of pancreas	None	CgA, PP
