Abstract:
Objective To analyse the value of serum alpha fetoprotein(AFP),keratin antigen 21-1(CY-FRA21-1)and neuron specific enolase(NSE)in the diagnosis and prognosis of lung cancer.Methods A total of 89 patients with primary lung cancer were selected as the primary lung cancer group from June 2014 to June 2016.The other 59 cases of benign lung disease were selected as the benign lung disease group,and 63 cases of healthy physical examination were collected as normal group.The content of AFP,CYFRA21-1 and NSE were detected by electrochemiluminescence assay.Results Before treatment,the levels of AFP,CYFRA21-1 and NSE in the benign lung disease group and the primary lung cancer group were significantly higher than those in the normal group,those in the primary lung cancer group were significantly higher than those in the benign lung disease group(P<0.05).The levels of AFP,CYFRA21-1 and NSE in patients with stage Ⅲ aand Ⅲ b-Ⅳ were significantly higher than those in patients with stage Ⅰ - Ⅱ,and those in Ⅲ b- Ⅳ stage were signifi-cantly higher than those in Ⅲ astage(P<0.05).The sensitivity,specificity,accuracy of two joint tests were significantly higher than those of the single test,those of the three joint tests were significantly higher than those of the single test and the two combined tests,and the differences were statistically significant(P<0.05).The AFP,CYFRA21-1 and NSE of the patients in the ineffective group were significantly higher than those in the effective group,and the differences were statistically significant(P<0.05).Conclusion Tumor markers AFP,YFRA21-1 and NSE are of great value in the diagnosis and treatment of lung cancer,joint detec-tion could improve the positive rate and accuracy of diagnosis.
