Abstract:
Objective To study the clinical value of measurement of serum neuron specific enolase (NSE) and gastrin for lung cancer. Methods serum NSE and gastrin were measured with ABC ELISA and Radioimmunoassay in 30 healthy subjects(C),25 patients with benign pulmonary diseases (BPD),55 patients with non small cell lung cancer (NSCLC) and 15 patients with small cell lung cancer (SCLC).Reaults The serum concentrations of NSE and gastrin had significant difference in the four groups ( P 0 001).The sensitivity,specificity and accuracy of NSE for SCLC were 80,88 and 86%,gastrin for NSCLC were 69,65 and 60%,respectively.After the patients with lung cancer were treated,serum levels of NSE and gastrin were significantly decreased in SCLC ( P 0 001),but levels of gastrin were decreased in NSCLC only ( P 0 001). Conclusion NSE should be used in adjuvant diagnosing,preoperative histological typing and therapy monitoring for SCLC,and gastrin for NSCLC.
