Abstract:
OBJECTIVETo determine the cut-off value of serum neuron-specific enolase (NSE) level for distinguishing small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC).
METHODSSerum NSE levels were measured by enzyme-linked immunosorbent assay in 137 patients with NSCLC or SCLC, and the best cut-off value was analyzed using ROC curve.
RESULTSThe positivity rate of serum NSE was significantly higher in patients with SCLC than in those with NSCLC (P<0.01). The best cut-off value was 15.45 microg/L using ROC curve, which gave a sensitivity of 66.7% and specificity of 65.7%.
CONCLUSIONSerum NSE level may allow simple and cost-effective differentiation of SCLC and NSCLC.
