DNA Methylation Combined With Artificial Intelligence Imaging to Identify Lung Nodules

DNA Methylation Combined With Artificial Intelligence Imaging for Early Benign and Malignant Differentiation of Lung Nodules:an Observational,Single-center Clinical Trial(MAGIC Study)

Lung cancer is the leading cause of cancer deaths,and the key to reducing mortality in lung cancer patients is early diagnosis and treatment.Currently,peripheral blood DNA methylation is a novel in vitro molecular marker for tumors.Meanwhile artificial intelligence diagnostic system can further improve the diagnostic ability.The purpose of this study is to apply the overall DNA methylation level (i.e.,methylation profile) and the altered methylation degree of specific genes as tumor diagnostic indexes,and combined with the artificial intelligence imaging technology for the early and accurate diagnosis of lung cancer,to achieve the early detection,diagnosis,and treatment of lung cancer,and to effectively reduce the mortality rate of lung cancer.
