Abstract: OBJECTIVE: To investigate incidence characteristics and trends of stomach cancer in the Nanshan District of Shenzhen city from 2011 to 2019, and to provide bases for prevention and control strategies of gastric cancer. METHODS: Based on the data of stomach cancer which were collected by the Shenzhen Chronic Disease Prevention and Management Office,the incidence and age-standardized rates (ASR) of stomach cancers were calculated. The annual percent change (APC) was used to evaluate the trend of stomach cancer in the District. RESULTS: From 2011 to 2019,there were 498 new cases of stomach cancer. The incidence rate was 7.21×10^-5,the ASR China was 1.399×10^-4,and the ASR world was 1.518×10^-4. The incidence rate of male was 8.35×10^-5,the age-standardized incidence rates for standard Chinese population and for world population were 1.809×10^-4 and 2.090×10^-4,respectively. The incidence rate of female was 5.99×10^-5, the age-standardized incidence rates for standard Chinese population and for world population were 11.71/10⁵ and 1.316×10^-4,respectively. The incidence for male was significantly higher. In terms of age distribution,the incidence began to rise rapidly after the age of 45 and reached a peak at the age group of 80-85 years old, when the incidence was 9.087×10^-4. Over time,the incidence of stomach cancer was stable. CONCLUSION: The incidence of stomach cancer in the Nanshan District of Shenzhen City was stable. The data indicate that strengthening prevention and control on stomach cancer in high-risk male groups over 45 years old is needed.
