Pancreatic Cancer Symptoms and Presentation
Primary Symptoms
- Abdominal pain, often radiating to the back, is one of the three main symptoms and can become persistent as the disease progresses 1, 2
- Weight loss, severe and rapid, is common and usually associated with unresectability 1, 2
- Jaundice, painless, often occurs with tumors in the head of the pancreas due to bile duct obstruction 3, 4, 5
- New-onset diabetes, about 5% of pancreatic cancer patients develop diabetes mellitus within two years before diagnosis, making recent-onset diabetes in older patients a potential warning sign 1, 2
- Nausea and vomiting are common symptoms that may occur due to tumor effects or as part of general disease progression 1, 6
- Anorexia and malaise, loss of appetite and general feeling of unwellness, are frequently reported 1, 2
- Steatorrhea, fatty stools, due to exocrine pancreatic insufficiency 3, 4, 5
- Early satiety, feeling full quickly when eating, particularly in cases with gastric outlet/duodenal obstruction 6, 7
Symptom Presentation Based on Tumor Location
- Head of pancreas tumors (60-70% of cases) are more likely to cause early jaundice due to bile duct compression 3, 4
- Body and tail tumors (20-25% of cases) are usually diagnosed at more advanced stages 3, 4
- Jaundice typically only occurs with metastatic disease to the liver in body and tail tumors 6
Late-Stage Symptoms and Signs of Unresectability
- Persistent back pain suggests retroperitoneal infiltration 1
- Marked and rapid weight loss indicates aggressive disease 1
- Palpable and fixed epigastric mass is a sign of locally advanced disease 1
- Ascites, fluid accumulation in the abdomen, is a symptom of advanced disease 6, 7
- Enlarged supraclavicular lymph node (Virchow's node) indicates metastatic spread 1
- Migratory thrombophlebitis, though rare as a first symptom, is associated with pancreatic cancer 6, 7, 8
