Serum tumor markers and molecular biological diagnosis in pancreatic cancer.

Abstract excerpt

Recent studies on genetic abnormalities in pancreatic ductal cancer have led to the investigation of tumor markers and genetic markers in both serum and pancreatic juice (PJ). Serum type 1 chain carbohydrate antigens such as CA19-9 are positive in nearly 80% of patients with pancreatic cancer (PCa), of which most are in advanced stage, whereas false-positive rates are relatively high at 20%-30% in benign...
