Abstract: Objective The Objective of this study was to understand the trend and age change of gastric cancer in China,and to provide evidence for the prevention and control of gastric cancer.Methods Based on 22 registries with continuous data,the incidence data of gastric cancer from 2000 to 2015 were collated,and the incidence trend analysis was performed using Joinpoint software.The average age of onset between 2000 and 2015,the standardized age-specific incidence composition in 2000 and 2015 were analyzed.The birth cohort was constructed and the incidence and age-specific incidence were also calculated.Results From 2000 to 2015,the incidence of standardized gastric cancer in 22 cancer registration regions in China showed a downward trend,with an average annual decrease of 3.0%(-3.5%~-2.4%).The age of this disease onset in the population showed an increasing trend,after the population structure standardization,except for rural areas,this trend disappeared.The age of this disease onset in rural areas was raised,and the proportion of older patients was also increased.Conclusion The incidence of gastric cancer is declining,and the average age of onset shows an increasing trend.
