To investigate the level of the core knowledge and related factors of cancer prevention and treatment among residents in the upper gastrointestinal cancer screening areas of Sichuan Province in 2018. From April to May 2018, a total of 1 386 residents from Chaotian District of Guangyuan, Enyang District of Bazhong, Nanjiang County of Bazhong, Cangxi County of Guangyuan, Shehong County of Suining, Yilong County of Nanchong, Xichong County of Nanchong and Xuanhan County of Dazhou were recruited in this study. A questionnaire survey was conducted to collect basic demographic characteristics and the knowledge of cancer prevention and treatment. The level of the core knowledge of cancer prevention and treatment of different population was analyzed. A multivariate linear regression model was performed to analyze the related factors. In total, 80.9% (1 120) of all subjects was 25-64 years old and 48.0% (665) were male. The total number of questions answered by the subjects was 18 018, of which 12 147 were known, and the overall awareness rate among the respondents was 67.42%. The female respondents, respondentsaged 65 years old and over, with junior college education or above, and worked in government institutions had a good performance of the core knowledge (0.05), about 70.11% (6 571/9 373), 69.23% (387/559), 76.05% (6 327/8 320), and 77.09% (5 602/7 267) respectively. The results of multivariate linear regression showed that the older the age [β=0.871 (95: 0.623-1.119)], the higher the educational level [β=0.741 (95: 0.540-0.943)], the more questions respondents could know; compared with the workers in government organization and institution, workers in enterprise [β=-2.913 (95:-3.499--2.327)], farming workers [β=-0.635 (95:-1.175--0.095)] and other occupation people [β=-1.126 (95:-1.663--0.589)] could know fewer questions. In 2018, the level of the core knowledge of cancer prevention and treatment among residents in upper gastrointestinal cancer screening areas of Sichuan Province was relatively high. Age, education level and occupation were relevant factors.
