[Determination of carcinoembryonic antigen in lung cancer using an immunoenzyme assay].

Abstract

Elevation of the carcinoembryonal antigen concentration in patients with pulmonary carcinoma is directly dependent on the tumor process dissemination. Measurements of mucinous cancer-associated antigen, neurospecific enolase, CA-125 improve the reliability of enzyme immunoassays of tumor markers of lung cancer. Measurements of carcinoembryonic antigen over the course of treatment may become a valuable test permitting an objective assessment of the treatment efficacy.
