Objective: Analyze the cancer screening status of the cancer screening program in urban areas in Shaanxi province in 2019-2020. Methods: The early diagnosis and early treatment project for urban cancers carried out high-risk population screening for 5 types of high-incidence malignant tumors (breast cancer, lung cancer, upper gastrointestinal cancer, liver cancer, and colorectal cancer) in urban areas. Three prefecture-level cities in Shaanxi province with a population of over 1 million (Xi'an, Baoji, and Shangluo) were selected, and 4 communities with a relatively good working foundation were selected in each city. The general population aged 45-74 years was surveyed on the principles of informed consent and voluntariness, and high-risk groups identified through the questionnaire were further subjected to free endoscopy, ultrasound, CT, and other clinical screenings. The high-risk rates, screening compliance rates, and positive detection rates of the above 5 types of malignant tumors were analyzed. Results: A total of 19 632 people completed the survey effectively, with the proportion of male participants (40.0%) lower than that of females (60.0%). A total of 10 102 high-risk groups were identified, with an initial screening high-risk rate of 51.5%, and the high-risk rates for the 5 types of cancers were 24.1% for breast cancer, 28.6% for lung cancer, 9.1% for upper gastrointestinal cancer, 4.0% for liver cancer, and 20.0% for colorectal cancer. Among the 14 960 person-time initially assessed as high-risk, 5 129 person-time received clinical screening, with a screening compliance rate of 34.3%. The number of people receiving clinical screening and the screening compliance rates for the 5 types of cancers were 1 192 (41.9%) for breast cancer, 2 081 (37.1%) for lung cancer, 574 (32.0%) for upper gastrointestinal cancer, 404 (51.3%) for liver cancer, and 878 (22.3%) for colorectal cancer, with positive detection numbers and rates of 179 (15.0%) for breast, 289 (13.9%) for lung, 9 (1.6%) for upper gastrointestinal, 14 (3.5%) for suspected liver, and 67 (7.6%) for colorectal, respectively. Conclusion: The cancer screening status of the cancer screening program in urban areas in Shaanxi province is beneficial for the detection of precancerous lesions and early cancer patients, and improving the early diagnosis and treatment rate of patients, but the public participation rate is not high, and the project management model and technical plan need to be further improved.
目的： 分析陕西省2019—2020年城市癌症早诊早治项目的筛查情况。 方法： 城市癌症早诊早治项目针对城市地区5类高发恶性肿瘤（乳腺癌、肺癌、上消化道癌、肝癌、结直肠癌）开展高危人群筛查。选择陕西省3个人口超过100万的地级市（西安市、宝鸡市、商洛市），各选择工作基础较好的4个社区，面向年龄45～74岁一般人群，在知情同意、自愿的原则下进行相关恶性肿瘤流行病学问卷调查，对问卷评估出的高风险人群再进行免费内镜、超声、CT等临床筛查。分析以上5种恶性肿瘤的高风险率、筛查依从率及阳性检出率。 结果： 共19 632人有效完成调查，男性参与筛查的比例（40.0%）低于女性（60.0%）。共评估出高危人群10 102人，初筛高风险率51.5%，5类癌种的高风险率分别为乳腺癌24.1%、肺癌28.6%、上消化道癌9.1%、肝癌4.0%、结直肠癌20.0%。初筛被评估为高危人群的14 960人次中，共5 129人次接受临床筛查，筛查依从率为34.3%。5类癌种接受临床筛查的人次和筛查依从率分别为乳腺癌1 192人次（41.9%）、肺癌2 081人次（37.1%）、上消化道癌574人次（32.0%）、肝癌404人次（51.3%）、结直肠癌878人次（22.3%），阳性检出人次和检出率分别为乳腺179人次（15.0%）、肺289人次（13.9%）、上消化道9人次（1.6%）、肝14人次（3.5%）、结直肠67人次（7.6%）。 结论： 陕西省城市癌症早诊早治项目有利于发现癌前病变和早癌患者，提高患者早诊早治率，但群众参与率不高，需进一步完善项目管理模式与技术方案。.
