ON THE LABORATORY DIAGNOSIS OF THE TUMORS OF PANCREATICOBILIARY AREA IN PATIENTS WITH MECHANICAL JAUNDICE

Blood investigation of tumor markers CA-19-9, carcino-embryonic antige n and alpha-fetoprotein was performed in patients with mechanical jaun dice due to tumor involvement of the pancreatobiliary area and a nontu mor process. It was concluded that the use of CA-19-9-marker and carci noembryonic antigen provided a successful differential diagnosis betwe en jaundice resultant from tumor and nontumor diseases. Alpha-fetoprot ein turned to be of no informative value. Analysis of tumor markers co ntents in patients with pancreatobiliary tumors demonstrated the usefu lness of them in the preoperative assessment of surgical intervention practicability.
