Early diagnosis is the key to improve the prognosis of gastric cancer. How to screen out high-risk subjects of gastric cancer in population is a hot spot. Serum-based early detection of gastric cancer is suitable for high-risk population screening, which is more convenient and safer. This article reviews the diagnostic value of serum biomarkers for gastric cancer, including serum DNA methylation, various RNAs, pepsinogen, gastrin, osteopontin, MG7-Ag and CA724. Until now, there is still lack of ideal biomarkers for gastric cancer, and searching for specific RNAs may be promising for early diagnosis and screening of gastric cancer.
早期诊断是胃癌患者良好预后的关键，如何在人群中筛查胃癌高危者是当前的一个热点。基于血清的胃癌早期诊断检测适用于高风险人群筛查，更加方便、安全。本文介绍了胃癌的血清生物学标志物的研究进展，包括血清DNA甲基化、各种RNA、胃蛋白酶原、胃泌素、骨桥蛋白、MG7-Ag和CA724等血清生物学标志物在胃癌诊断方面的价值，并指出寻找胃癌特异的RNA是比较有前景的早期诊断和筛查方法。
