Serum fragment of cytokeratin subunit 19 measured by CYFRA 21-1 immunoradiometric assay as a marker of lung cancer.
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 prove...
متن کاملCYFRA 21-1, a cytokeratin subunit 19 fragment, in bronchoalveolar lavage fluid from patients with interstitial lung disease.
1. It has been suggested that CYFRA21-1, a cytokeratin subunit 19 fragment, is potentially useful for diagnosis and monitoring of lung carcinoma. However, serum levels of CYFRA21-1 are also increased in a high proportion of patients with interstitial lung disease. In this study we measured CYFRA21-1 levels in bronchoalveolar lavage fluid from 10 normal subjects, 18 patients with idiopathic pulm...
متن کاملSerum cytokeratin 19 fragment in advanced lung cancer: could we eventually have a serum tumor marker?
INTRODUCTION Lung cancer is one of the most lethal malignancies; however, no serum marker has been routinely recommended until now. METHODS THIS IS A PROSPECTIVE CASE CONTROL STUDY INCLUDING TWO GROUPS OF PATIENTS: Group I-patients with advanced lung cancer and Group II-patients with benign lung disease as control. Serum cytokeratin 19 (CK19) fragment levels were measured at baseline by real-...
متن کاملCYFRA 21-1 as a tumour marker for bronchogenic carcinoma.
Despite extensive research, the role of the commonly employed tumour markers in the diagnosis of lung carcinoma is yet to be clarified. The utility of a new marker, CYFRA 21-1, in the preoperative evaluation of patients with bronchogenic carcinoma was investigated. CYFRA 21-1 was determined with a radiometric assay in serum of 280 patients with lung cancer and 208 patients with various nonmalig...
متن کاملCYFRA 21-1 in urine: a diagnostic marker for endometriosis?
Diagnostic workup of endometriosis usually involves laparoscopic inspection and histological examination of biopsies. Unequivocal laboratory parameters for this ailment have not been available in routine diagnostic evaluations thus far. In this study, we examined urine concentrations of cytokeratin 19 (CYFRA 21-1), a structural protein specific for epithelia. We performed immunoassays for CYFRA...
