ABSTRACT
BACKGROUND@#The incidence and mortality of lung cancer often rank first in all malignant tumors. DNA methylation, as one of epigenetics, often participates in the development and progression of tumors. CDO1 as a tumor suppressor gene always undergoes methylation changes early in tumor development. Therefore, this study aims to discuss the value of CDO1 methylation in the early diagnosis of lung cancer.@*METHODS@#Peripheral blood samples were collected from tumor patients and healthy people. Detection of the methylation level of CDO1 in plasma by sulfite modification and quantitative real-time PCR.@*RESULTS@#The level of gene methylation in peripheral blood of lung cancer patients was significantly higher than that of benign lung disease patients and healthy people. The methylation level of CDO1 was significantly different in the stratified comparison of gender, lymph node metastasis and tumor-node-metastasis (TNM) stage (P<0.05). The sensitivity and specificity of CDO1 were 52.2% and 78.6%, respectively. The overall accuracy of the diagnosis was significantly higher than that of the clinical tumor markers, and the sensitivity of CDO1 to stage I and II patients was the highest (40.8%, 47.1%). In addition, CDO1 could effectively increase the sensitivity of diagnosis in multiple joint examinations.@*CONCLUSIONS@#Detecting the methylation level of CDO1 has a potentially huge advantage for the early diagnosis of lung cancer.
