Abstract:

Lung cancer is one of the most common malignant worldwide, and one of common cause of camcer-related death, the most which seriously human health threaten. Early diagnosis of lung cancer is crucial to the good prognosis lung cancer, which can reduce the fatality rate significantly. Abnormal expression of markers in early lung cancer has become the most promising scientific exploration in the field of early diagnosis. At present, clinical serological markers of lung cancer include carcinoembryonic antigen (CEA), neuron specific enolization enzyme (NSE) and cytokeratin 19 fragment (CYFRA21-1), carbohydrate antigen 125(CA125), and pro-gastrin-releasing peptide(Pro-GRP). With the rapid development of molecular biology and high-throughput technology platform, new biomarkers, such as heat shock protein 90α (HSP90α), autoantibodies, circulating tumor DNA(ctDNA), microRNA(miRNA), and circulating tumor cells (CTC) are emerging. This paper mainly focuses on the functions and characteristics of new tumor biomarkers in the early diagnosis of lung cancer.

Key words: Lung cancer, Heat shock protein 90α, Autoantibody, Circulating tumor DNA, MicroRNA
