Abstract:
Objective To investigate the clinical value of tissue polypeptide specific antigen(TPS),neuron-specific enolase(NSE),carcinoembryonie antigen(CEA)and CA125 in serum of small cell lung cancer(SCLC)patients and its significance in diagnosis and disease monitoring.Methods Serum leveh of TPS was detected using ELISA and serum levels of NSE,CA125 and CEA was detected using ECLin 27 1 SCLC patients.80 pulmonary benign disease patients and 224 normal healthy people.Diagnostic values of these tumor markers were analyzed by receiver operative characteristic(ROC)curve.Results The levels of TPS,NSE,CA125 and CEA iu the serum of SCLC group were signifieanfly higher than those in pulmonary benign disease and healthy group(Z＞1.90,P＜0.01).The levels of TPS and NSE in the serum of extensive stage small cell lung cancer(ESCLC)patients were significantly higher than those in limited stage small cell lung cancer(LSCLC)(Z=2.69,2.27,P=0.009,0.02 respectively).,The level of TPS and NSE showed statistical significance among SCLC patients with different prognosis after therapy(Z=4.06,3.11.P=0.001,0.007 respectively).The TPS+NSE showed the highest sensitivity of 86.7%,and the specificity,PPV and NPV were 75.0%,81.0% and 82.2%,respectively.Conclusions Serum levels of TPS,NSE,CA125 and CEA are useful for SCLC diagnosis.TPS+NSE shows the highest clinical values in SCLC diagnosis and prognosis.
