[Value of neuron specific enolase levels and squamous cell carcinoma antigen in bronchial lavage fluid in patients with lung cancer].

The aim of the study was to assess a value of NSE and SCC Ag level determination in bronchial lavage fluid in patients with lung cancer. It was found out that NSE levels in bronchial lavage fluid were much lower than in serum and did not differentiate patients with small cell lung cancer from patients with non small cell lung cancer and nonmalignant lung diseases. Bronchial lavage SCC Ag levels were significantly higher than serum SCC Ag levels. Although determination of SCC Ag levels in bronchial lavage was also not helpful in differential diagnosis.
