Abstract:

Objective To investigate the role of plasma thioredoxin reductase(TR) in monitoring the efficacy of chemotherapy in lung cancer. Methods Totally,482 lung cancer patients were classified into 2 groups according to the efficacy of chemotherapy,which were unbenefited group(211 cases) and benefited group(271 cases). TR,carcinoembryonic antigen(CEA),squamous cell carcinoma antigen(SCC-Ag),cytokeratin 19 fragment(CYFRA 21-1),neuron-specific enolase(NSE) and gastrin-releasing peptide precursor(ProGRP) levels were determined. Receiver operating characteristic(ROC) curve was used to evaluate the roles of single and combined determinations of each indicator in judging the efficacy of chemotherapy. Results TR,CEA and NSE levels in unbenefited group were higher than those in benefited group(P<0.05),and there was no statistical significance in SCC-Ag,CYFRA 21-1 and ProGRP levels between the 2 groups(P>0.05). The positive rate of TR in unbenefited group was 56.40%,which was higher than that in benefited group(13.16%)(P<0.05). ROC curve analysis showed that the areas under curves(AUC) of TR,CEA,CYFRA 21-1,SCC-Ag,NSE and ProGRP single determinations to judge the efficacy of chemotherapy were 0.759,0.667,0.579,0.530,0.619 and 0.544,respectively. The AUC of combined determinations of TR+CEA,TR+CEA+CYFRA 21-1,TR+CEA+CYFRA 21-1+NSE and TR+CEA+CYFRA 21-1+NSE+ProGRP were 0.757,0.749,0.752 and 0.788,respectively. TR did not correlate with CEA,NSE,SCC-Ag,CYFRA 21-1 and ProGRP(r=0.05,0.02,-0.15,0.05 and 0.10,P>0.05). Conclusions TR may serve as a biomarker for monitoring lung cancer curative effect.
