Tissue polypeptide specific antigen (tps) and cytokeratin 19 fragment (CYFRA 21.1) immunoradiometric assay in non small cell lung cancer evaluation.

The aim of our work was the evaluation of the immunoradiometric assay (IRMA) of two cytokeratinic markers, TPS and CYFRA 21.1, in clinical setting on non small cell lung cancer (NSCLC). Serum samples were obtained from 148 untreated NSCLC patients, 60 patients with non malignant lung diseases and 100 healthy subjects: TPS and CYFRA 21.
