Retrospective Study to Determine Diagnostic Utility of 6 Commonly Used Lung Cancer Biomarkers Among Han and Uygur Population in Xinjiang Uygur Autonomous Region of People's Republic of China

Abstract: Early diagnosis was the main way to improve the survival rate of lung cancer patients. At present, the methods to diagnose lung cancer were varied, but early diagnosis of lung cancer was still difficult. In experimental and clinical studies, lung cancer related tumor markers were helpful to the early diagnosis of lung cancer. So far, there were many studies about lung cancer related tumor markers in China, but the subjects in these studies were almost the Han population. There were few studies about the Uygur population. Xinjiang was a multi-ethnic region in China, the ratios of Han and Uygur population were 40% and 45%, respectively. Xinjiang also was a high incidence area of lung cancer in China. The purpose of this study was to research the application of 6 tumor markers in Uygur and Han lung cancer patients in XinJiang, China. The study collected 342 cases who were diagnosed as lung cancer in Tumor Hospital Affiliated to XinJiang Medical University from May 2012 to December 2012. Serum concentrations of squamous cell carcinoma (SCC), cytokeratin fragment 19 (CYFRA21-1), carcino-embryonic antigen (CEA), carbohydrate antigen 125 (CA125), precursor of gastrin-releasing peptide (Pro-GRP), and neuron-specific enolase (NSE) were tested for every patient before radiation, chemotherapy, or surgery. The serum concentrations of SCC, CYFRA21-1, CEA, CA125, and Pro-GRP were assayed using the micro-particle luminescence analysis testing by the Abbott ARHCITECT i2000SR immun...
