title: Evaluation of Cyfra 21-1 as a marker for lung cancer.
abstract: The sensitivity and specificity of Cyfra 21-1 as marker for lung cancer was evaluated in comparison with carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC) and neuron-specific enolase (NSE). Patients with histologically verified lung cancer and different groups without lung cancer were investigated. Sensitivity of Cyfra 21-1 (cut-off level 2.9 micrograms/l) was 40% for non-small cell lung cancer (NSCLC), 60% for rare histological types and 21% for small cell lung cancer (SCLC). In NSCLC sensitivity of Cyfra 21-1 was 35% for squamous cell carcinoma and 41% for adenomous carcinoma. The highest sensitivity for CEA was 45% in NSCLC, with 57% in the subtype of adenomous cell carcinoma; for SCC 30% was achieved in squamous cell carcinoma and for NSE 66% sensitivity was reached in SCLC. In our patients Cyfra 21-1 and CEA appeared equally useful for evaluating patients with NSCLC.
