Neuron-specific enolase in the diagnosis and therapy monitoring of lung cancer: a comparison with CEA, TPA, ferritin and calcitonin.
The significance of neuron-specific enolase (NSE) in the diagnosis and treatment monitoring of lung cancer was investigated in comparison with such established tumour markers as carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA), ferritin and calcitonin. We determined the serum concentrations of these tumour markers in 25 patients with small cell lung cancer (SCLC), 30 patients with non small cell lung cancer (NSCLC), and 38 patients with benign pulmonary diseases (BPD). In 14 patients with lung cancer, it was possible to follow up the behaviour of the tumour markers under treatment for up to 16 months. Calcitonin proved to have a surprisingly low sensitivity for SCLC. The utility of TPA and of ferritin was restricted, although the sensitivity was comparably high, by the high rate of false positive results. For NSCLC, CEA proved to be the best tumour marker. At present, NSE appears to be the tumour marker with the greatest specificity and sensitivity for SCLC. Its determination in the diagnosis, treatment and follow-up of SCLC makes good sense.
