[目的]评价食管癌高发区早诊早治项目筛查人群食管癌及癌前病变的患病情况。[方法]在四川省食管癌高发地区,采取整群随机抽样的方法选择至少一个乡或村作为筛查对象,对40~69岁人群采取内镜下碘染色及指示性活检技术进行筛查,并行病理学诊断。[结果]全省合计筛查11021人,筛查率100.19%;重度异形增生/原位癌及以上病人检出168例,检出率为1.53%;其中食管癌61例,检出率为0.55%。全省早诊率67.86%;治疗率67.26%。[结论]在食管癌高发区人群中存在着一定数量的无明显临床症状的癌前病变及早期食管癌患者,对该部分高危人群进行食管癌普查并进行癌症综合知识宣传,提高其防癌意识,是提高早期食管癌检出率,做好食管癌二级预防工作的关键。
[Objective] To evaluate the prevalence of esophageal cancer and precancerous lesions in early screening and early diagnosis of esophageal cancer in high incidence areas. [Methods] In the high risk area of esophageal cancer in Sichuan Province, at least one township or village was selected as the screening target by cluster random sampling method. The endoscopic iodine staining and the indicator biopsy technique were used to screen the 40 ~ 69 age group. Parallel pathological diagnosis. [Results] The total number of screening in the province was 11021, with a screening rate of 100.19%. 168 cases with severe dysplasia / carcinoma in situ and 168 cases with the detection rate of 1.53%. Among them, 61 cases of esophageal cancer were detected with a detection rate of 0.55 %. The province’s diagnosis rate of 67.86%; treatment rate of 67.26%. [Conclusion] There are a certain number of patients with precancerous lesions and early esophageal cancer without significant clinical symptoms in the population with high incidence of esophageal cancer. The esophageal cancer screening and propaganda of comprehensive cancer knowledge are carried out to improve the awareness of cancer prevention , Is to improve the detection rate of early esophageal cancer, esophageal cancer do secondary prevention work.
