The value of tumor markers in monitoring of non-small cell lung cancer / 中华全科医师杂志

ABSTRACT

One hundred and four patients with non-small cell lung cancer (NSCLC) and 17 patients with benign lung lesions were enrolled in the study. Carcinoembryonic antigen ( CEA), neural specific enolaee (NSE) and cytokemtin 19 fragment (CYFRA21-1) in serum were detected by dectruchemiluminescence method before and after operation. The serum levels of three markers in preoperative NSCLC patients were significandy higher than those of benign pulmonary diseases group (t = 7. 930, 5.568, 6. 110, P <0. 05) ; but there were no significant differences between postoperative NSCLC patients and benign disease patients (t = - 0.034, 1. 242, 0.691, P > 0.05 ). There were significant differences in serum levels of CEA, NSE and CYFRA21-1 before and after operation in NSCLC group ( t = 5.419, 4.722, 5.779, P < 0.05 ) ; but not in benign pulmonary disease group ( t = - 1.244, 0.732, 1. 000, P >0.05). This study indicates that detection of serum CEA, NSE and CYFRA21-1 is of monitoring value for treatment of non-small cell lung cancer.
