title: Clinical relevance of tumour markers CA 19-9 and CA-50 in sera from patients with pancreatic duct carcinoma.
abstract: Serum levels of the tumour antigens CA 19-9 and CA-50 and their relation to the extent of the disease were studied in 97 patients with carcinoma of the pancreas. Of 13 patients with normal serum concentrations of CA 19-9, 11 (84.6%) had irresectable disease, whereas 87.5% of the patients with resectable disease expressed antigen levels above cut-off. Following attempted radical surgery, preoperatively elevated serum levels decreased in eight patients (50%). Unchanged and high levels were associated with residual disease and early death. Clinical signs of recurrence were preceded by elevated serum levels of both tumour antigens.
