胃癌是世界上第4大常见的恶性肿瘤,死亡率在恶性肿瘤中位居第2[1]。胃癌的预后与肿瘤的分期密切相关,早期胃癌患者5年生存率超过90%,而进展期胃癌伴转移者5年生存率不足10%[2]。早发现、早诊断、早治疗是提高胃癌生存率的关键。目前临床上确诊胃癌的金标准为胃镜活检,该方法不适合作为筛选普查的手段,血清肿瘤标志物的检测由于其简单快捷、经济无创可用于胃癌早期筛选
Gastric cancer is the fourth most common malignancy in the world, and its mortality rate ranks the second among malignant tumors [1]. The prognosis of gastric cancer is closely related to the stage of the tumor. The 5-year survival rate of patients with early gastric cancer is more than 90%, while the 5-year survival rate of patients with advanced gastric cancer is less than 10% [2]. Early detection, early diagnosis and early treatment is the key to improve the survival rate of gastric cancer. Currently the gold standard for clinically diagnosed gastric cancer is gastroscopy biopsy, which is not suitable as a screening screening method. The detection of serum tumor markers can be used for early screening of gastric cancer due to its simple and quick, economical and noninvasive method
