The invasion and metastasis of esophageal carcinoma is associated with several tumor marker on oncogenesi and tumor development,including matrix metalloproteinase,cell adhesion molecules CD44,pituitary-tumour transforming genes.Studies have shown that these tumor markera are over-expression in esophageal carcinoma,which affect the progress and prognosis of esophageal carcinoma,and their specificity and value for clinical application need to be futher studied.

Objective To explore the diagnosis value of expression level of peripheral blood microRNA-21 in early gastric cancer patients. Methods In 52 patients with Tis gastric cancer and 40 healthy subjects, expression levels of microRNA-21 in peripheral blood were quantitatively detected by real-time quantitative PCR(qRT-PCR),and diagnostic value of expression level of microRNA-21 in peripheral blood were evaluated by receiver operator characteristic (ROC) curve. Results Relative quantity expression level of microRNA-21 in peripheral blood in gastric cancer group and healthy subjects group were 2.286±0.592 and 1.318±0.357, and there was statistical significance (U=136.500, P=0.000). ROC curve analysis showed that ROC curve area of expression level of microRNA-21 in peripheral blood in diagnosing gastric cancer was 0.934(95%CI 0.887-0.982, P=0.000), and the best diagnostic boundary point value was 1.912. The sensitivity of expression level of microRNA-21 in peripheral blood in diagnosing gastric cancer was 86.5%, and the specificity was 95.0%. Conclusion Expression level of microRNA-21 in peripheral blood has important diagnostic value in early gastric cancer.
