Investigation progress of molecular biomarkers from body fluids in early gastric cancer / 中国肿瘤临床

ABSTRACT

The mechanism of gastric cancer (GC) remains unclear. The diagnosis and treatment of GC undergo rapid development, but the prognosis of the patients remains dismal. The key procedure to improve overall survival is early detection and treatment. However, classic tumor markers have several limitations in clinical practice because of their low sensitivity and specificity. Given the expansion of high throughput technologies, investigators have attained considerable progress in obtaining the benefits of molecular biomarkers through genomics and proteomics analysis. These findings provide new directions for the diagnosis and treatment of early-stage GC. Markers from body fluids, which can be easily obtained , are increasingly gaining attention. This article summarizes the progress of the investigation of molecular biomarkers in early GC using body fluids.
