消化道肿瘤一般多见于食道癌、胃癌与结直肠癌,近10年研究数据显示,胃癌已经成为全世界高发的恶性肿瘤,而食道癌、结直肠癌的全球发病率均呈上升趋势~([1-3]),其中食道癌患者的5年存活率低于10%,为预后最差的消化道肿瘤。食道肿瘤早期症状不明显,确诊率低,对消化系统破坏严重,患者生存质量较差,病变组织耐药性高,因此对高危人群进行早期筛查是提高早期病变发生率的重要手段,而特异性生物学标志
Gastrointestinal cancer generally more common in esophageal cancer, gastric cancer and colorectal cancer, nearly 10 years of research data show that gastric cancer has become a worldwide incidence of malignant tumors, while the global incidence of esophageal cancer, colorectal cancer are on the rise ~ ([ 1-3]), in which patients with esophageal cancer 5-year survival rate of less than 10%, the worst prognosis of gastrointestinal tumors. Early symptoms of esophageal cancer is not obvious, the diagnosis of low rates of serious damage to the digestive system, the poor quality of life of patients with high tissue resistance, so early screening of high-risk groups is an important means to improve the incidence of early lesions, and specific Sexual biology logo
