Abstract:
Objective To study the clinical significance of neuron specific enolase (NSE),carcinoembryonic antigen(CEA) and carcinoma associated antigen(CA125) in diagnosis,evaluation of therapy and monitoring metastasis and recurrence of lung cancer.Methods The levels of NSE,CEA and CA125 were detected in the sera from 30 healthy controls,48 patients with benign diseases,50 patients with non-small cell lung cancer(NSCLC) and 14 patients with small cell lung cancer(SCLC) by using microparticle enzyme linked immunoassay and bioantibodies sandwich one step assay by using streptavidin technique,respectively.Results The levels of NSE and CEA in the sera of patients with NSCLC and SCLC were significantly higher than those of healthy controls and patients with benign diseases (both P0 05).The levels of NSE CEA and CA125 decreased after the treatment and increased greatly with the metastasis and recurrence of the cancer.After the combination of NSE and CEA and CA125,the sensitivity significantly increased,but no difference was found in the specifity.Conclusion Measuring serum levels of NSE,CEA and CA125 are very useful in diagnosis,evaluation of therapy and monitoring of metastasis and recurrence of lung cancer.
