Clinical value of combined detection of of SCC and CEA in the diagnosis of lung cancer / 国际检验医学杂志

ABSTRACT

Objective To explore the clinical value of combined detection of SCC and CEA in the diagnosis of lung cancer.Methods 382 cases from January 2015 to April 2016 in the respiratory department of our hospital were selected in this survey.Among which 172 cases with lung cancer,110cases with benign lung diseases and 100 healthy person.The CEA and SCC content in serum of all these cases were determined by chemical chemiluminescence,and the diagnostic efficacy of lung cancer by CEA or SCC alone and CEA and SCC combined examination was compared.Results In lung cancer group,the serum levels of CEA and SCC content were significantly higher than those of the normal control group and lung benign disease group(P＜0.05),and benign lung disease group were significantly higher than that of the normal control group(P＜0.05).and compared with squamous cell carcinoma and small cell lung cancer,CEA has the highest content in adenocarcinoma(P＜0.05).Meanwhile,the content of SCC in squamous cell carcinoma was obviously higher than that of small cell lung cancer and adenocarcinoma(P＜0.05),The sensitivity of CEA was significantly higher than that of SCC(P＜0.05),and the sensitivity and negative predictive value in combined detection group was significantly higher than that of CEA or SCC(P＜0.05).Conclusion SCC and CEA could be used to identify different types of lung cancer,and the combination of the two methods could improve the positive diagnosis rate,facilitate the early detection of lung cancer,early treatment,has the promotion value.
