Abstract: Objective The aim of this study was to analyze the incidence and mortality of gastric cancer in cancer registration areas of Anhui Province in 2015,and provide basic data for the development of preventive measures for gastric cancer.Methods After quality review,the data of 22 cancer registries were included in the analysis.The incidence and mortality of gastric cancer were calculated according to region(urban and rural)and gender stratification.The Chinese standard population and the segi world population composition in 2000 were used to calculate the Chinese population and World population age-standardized incidence/mortality.Results A total of 9383 new cases of gastric cancer and 6681 deaths were reported in cancer registration areas of Anhui Province.The death-to-incidence ratio(M/I)of gastric cancer in this province was 0.71,the pathological diagnosis rate(MV%)was 64.19,and the recurrence rate of death was 2.59%.The crude incidence rate of gastric cancer in Anhui cancer registration regions in 2015 was 43.85/100 000(60.94/100 000 for men and 25.78/100 000 for women).The population standardization rate in China was 30.99/100 000 and the population standardization rate in the world was 30.86/100 000.The crude incidence rate in urban areas was 35.82/100 000,the standardization rate of the Chinese population was 25.00/100 000;the crude incidence rate in rural areas was 49.79/100 000,the standardization rate of the Chinese population was 35.52/100 000.The crude mortality of gastric cancer in Anhui registered areas in Anhui Province in 2015 was 31.22/100 000(43.74/100 000 for men and 17.99/100 000 for women).The population standardization rate in China was 21.33/100 000 and the population standardization rate in the world was 21.04/100 000.The crude mortality rate in urban areas was 25.55/100 000,and the standardized rate of Chinese population was 17.25/100 000;the crude mortality in rural areas was 20.51/100 000,and the standardized rate of Chinese population was 24.44/100 000.Conclusion The rural population and the male population must be the focus of prevention and treatment of gastric cancer.The early diagnosis and treatment of upper gastrointestinal cancer should be promoted,the detection rate of early gastric cancer should be increased,and the burden of disease caused by the incidence and death of gastric cancer should be reduced.
