Abstract excerpt

Cytokeratin 19 is a subunit of cytokeratin intermediate filament expressed in simple epithelia and their malignant counterparts. Therefore, it is expressed by respiratory epithelium cells and has been detected in lung cancer specimens. An immunoradiometric assay was used to detect a fragment of the cytokeratin 19, referred to as CYFRA 21-1, in the serum of 165 patients with histologically proved lung cancer (128...
