了解拉萨地区医务人员及居民对胃癌内镜筛查的知晓度，评估提高早期胃癌筛查依从性的方法。

采用单中心横断面研究，对拉萨地区医务人员及就诊患者、家属进行问卷调查。

共收集有效医务人员问卷145份，消化内科(28.3%)、其他内科(33.1%)和全科医生(13.1%)为主。消化内科医务人员在早期与进展期胃癌认知(92.3% vs. 65.6%)和推荐45岁以上筛查(100% vs. 90.3%)方面显著高于非消化内科医生(P<0.05)，但对胃癌筛查共识仔细阅读率均低于10%。共收集有效居民问卷125份，藏族占96.8%。胃癌家族史知晓率低(19.2%不了解)；64.0%不了解西藏高发癌种，仅17.6%认为胃癌高发；71.2%不了解幽门螺杆菌与胃癌的相关性，仅27.2%认为胃镜检查对预防胃癌有很大作用；45.6%认为胃癌必有症状、74.4%愿意接受筛查。有家族史组幽门螺杆菌检测率(57.1% vs. 34.0%)和胃镜检查率(57.1% vs. 21.3%)均高于无家族史组，无痛胃镜接受度更高(42.9% vs. 12.8%)。

拉萨地区医务人员对胃癌内镜筛查认知积极，但消化内科专业人员对筛查指南掌握不足，非消化内科人员对早期胃癌概念认知存在不足。居民对胃癌高危因素及早癌筛查认知水平较低，应加强医务人员指南培训，重视非消化内科专业人员教育，结合藏族文化特点开展健康宣教，推动胃癌筛查工作落实。

To investigate the awareness of gastric cancer endoscopic screening among medical staff and residents in Lhasa, Xizang, and to evaluate methods for improving compliance with early gastric cancer screening.

A single-center cross-sectional study was conducted using questionnaires administered to medical staff in Lhasa and patients and their families visiting Lhasa People′s Hospital.

A total of 145 valid questionnaires were collected from medical staff, primarily from gastroenterology (28.3%), other internal medicine departments (33.1%), and general practice (13.1%).The careful reading rate of gastric cancer screening consensus guidelines among gastroenterology staff was below 10%.Gastroenterology staff demonstrated significantly higher awareness than non-gastroenterology staff in distinguishing early from advanced gastric cancer (92.3% vs. 65.6%) and recommending screening for individuals over 45 years (100% vs. 90.3%, P<0.05). A total of 125 valid questionnaires were collected from residents, with Tibetans accounting for 96.8%.Awareness of family gastric cancer history was low (19.2% unaware); 64.0% were unaware of high-incidence cancers in Xizang, with only 17.6% recognizing gastric cancer as high-incidence; 71.2% were unaware of the relationship between Helicobacter pylori and gastric cancer; only 27.2% believed that gastroscopy has a significant role in preventing gastric cancer; 45.6% believed gastric cancer always presents with symptoms; 74.4% were willing to undergo screening.Residents with family history relied more on professional channels (57.1%) and interpersonal networks (42.9%), and showed significantly higher rates of H. pylori testing (57.1% vs. 34.0%) and gastroscopy (57.1% vs. 21.3%) compared to those without family history, with particularly higher acceptance of painless gastroscopy (42.9% vs. 12.8%).

Medical staff in Lhasa demonstrate positive attitudes toward gastric cancer endoscopic screening, but gastroenterology professionals have insufficient mastery of screening guidelines, and non-gastroenterology staff have insufficient understanding of early gastric cancer concepts.Residents have low awareness of gastric cancer risk factors and early cancer screening, but family history significantly improves their screening behavior.Guidelines training for medical staff should be strengthened, with particular emphasis on education for non-gastroenterology professionals, and health education should be conducted in combination with Tibetan cultural characteristics to promote the implementation of gastric cancer screening.
