Objective: To summarize the endoscopic screening findings in high-risk population of esophageal and gastriccarcinoma and analyze influential factors related to screening.
Methods: In seven selected cities and counties withhigh incidences of esophageal carcinoma, people at age of 40-69 were set as the target population. Those withgastroscopy contradictions were excluded, and all who were voluntary and willing to comply with the medicalrequirements were subjected to endoscopic screening and histological examination for esophageal, gastric cardiaand gastric carcinoma in accordance with national technical manual for early detection and treatment of cancer.
Results: In three years, 36,154 people were screened, and 16,847 (46.60%) cases were found to have precancerouslesions. A total of 875 cases were found to have cancers (2.42%), and among them 739 cases had early stagewith an early diagnosis rate is 84.5%. Some 715 patients underwent prompt treatment and the success rate was81.8%.
Conclusions: In a high-risk population of esophageal and gastric carcinoma, it is feasible to implementearly detection and treatment by endoscopic screening. Screening can identify potential invasive carcinoma,early stage carcinoma and precancerous lesions, improving efficacy through early detection and treatment. Theexploratory analysis of related influential factors will help broad implementation of early detection and treatmentfor esophageal and gastric carcinoma.
