  • Title: The prognostic value of the tumour markers CA 195 and CEA in patients with adenocarcinoma of the pancreas.
    Author: Taylor OM, Cooper EH, Benson EA, McMahon MJ.
    Journal: Eur J Surg Oncol; 1992 Oct; 18(5):508-13. PubMed ID: 1426303.
    Abstract:
    The serum levels of CA 195 were determined in 52 patients with histologically proven pancreatic carcinoma and compared with carcino-embryonic antigen (CEA), serum bilirubin and albumin. CA 195 levels were raised above the upper limit of 20 U/ml in 42 cases, giving a sensitivity of 80% for the detection of pancreatic carcinoma, whereas CEA was raised in only 55%. The levels of CA 195 and CEA were significantly higher in patients with metastatic disease, but potentially curable cases were not discriminated. Bilirubin and albumin levels were not significantly related to either the presence of metastases or the levels of the tumour markers. At the time of initial presentation, levels of both tumour markers correlated with the eventual duration of survival, but bilirubin and albumin did not. Significant increases in CEA and CA 195 were found in sequential blood samples, as the disease progressed. Neither CA 195 nor CEA was of sufficient sensitivity to be of value for screening, but both give an indication of the presence of metastases and of the subsequent duration of survival. CA 195 appeared to be more sensitive and might help to assess progress of the disease.
