Abstract:
Objective To evaluate the clinical value and relationship between the serum levels of the Pro-gastrin-releasing peptide 31-98 (ProGRP) , neuron-specific enolase NSE and the different pathohistology types of lung cancer. Methods 353 lung cancer patients were divided into two groups according to pathohistology types: SCLC group( n = 96), NSCLC group( n = 257). 90 lung benign lesion were taken as control group. ProGRP and neu-ron specific enolase in all patients were detected by ELISA. The levels of the ProGRP, NSE and the clinical value were compared among lung cancer,lung benign lesion patients and the different pathohistology types of lung cancer patients . Results The levels of the ProGRP and NSE of SCLC and NSCLC group were higher obviously than that of lung benign lesion( P <0.01 ). In SCLC diagnosis, the sensitivity, specificity, Youden index and Kappa value of the ProGRP and NSE were O. 7708,0. 9444,0. 7153,0.7111 and 0. 7604,0. 8778 ,0. 6382 ,0. 6355 in the monomial de-tection ; Those indexes above were 0.7604,0. 9667,0.7271 and 0. 7221 in combined assay of ProGRP + NSE( on se-quence test) ; and were O. 8229,0.9000,0. 7229 and 0. 7209 in combined assay of ProGRP + NSE( on parallell test). In NSCLC diagnosis,the above indexes were all lower. Conclusions in SCLC diagnosis,the detection of the serum ProGRP is superior to the detection of NSE, the combined assay of ProGRP + NSE (on parallell test) and Pro-GRP + NSE( on sequence test) are superior to the monomial detection of the ProGRP or NSE,and the combined as-say of ProGRP + NSE(on parallell test) is superiro to ProGRP + NSE(on sequence test) ; The diagnosis value of the monomial arid united detection of ProGRP and NSE to NSCLC is not as expected.
