Abstract:
Objective To investigate the diagnostic value of combined detection of serum gastrin-releasing peptide precursor (ProGRP),neuron specific enolization enzyme(NSE)and carcinoembryonicantigen(CEA)in small cell lung cancer(SCLC). Methods 471 patients with lung tumor from department of respiratory medicine and thoracic surgery and 162 healthy people from medical examination center were studied.Serum levels of ProGRP,NSE and CEA were detected by using electrochemi-cal luminescence method.ROC curves were drawn and the area under the curve (AUC)was calculated.Results The levels of ProGRP and NSE were significantly higher in patients with SCLC than those in NSCLC,lung benign disease group and normal control group (P <0.01).The levels of CEA were significantly higher in SCLC than those in patients with lung be-nign disease group and normal control group (P <0.05).The AUC of ProGRP,NSE and CEA in the diagnosis of SCLC were 0.933,0.777 and 0.554,respectively.The sensitivity of ProGRP,NSE and CEA in the diagnosis of SCLC were 82.6%,60.4%,41.6% and the specificity were 95.2%,83.3% and 71.7% respectively.The sensitivity of combined detec-tion of ProGRP,NSE and CEA was 91.3% and the specificity was 65.3%.Conclusion The serum ProGRP detection has a higher diagnostic value for SCLC.The combined detection of ProGRP,NSE and CEA is useful in the early diagnosis of SCLC.
