Abstract
OBJECTIVE: The incidence of gastric cancer is declining in parts of Asia including China. This study was designed to investigate the incidence and mortality trend of gastric cancer in different regions and ethnic groups in Xining of Qinghai-Tibet Plateau. METHODS: Data of gastric cancer from January 2009 to December 2016 were collected from Disease Control Center in Xining for repeated cross-sectional study. PRIMARY OUTCOME MEASURES: Gastric cancer. PARTICIPANTS: Xining resident population with pathological diagnosis of gastric cancer. MAIN OUTCOME MEASURE: Age, gender composition ratio, morbidity, mortality and trends. RESULTS: There were 4822 new cases of gastric cancer from 2009 to 2016, including 3583 males and 1239 females; 2290 cases were in villages and 2532 in towns. Male incidence rate (38.37/100,000) was higher than female (13.35/100,000). The incidence in rural areas (39.29/100,000) was higher than in urban areas (20.59/100,000). During 2009-2016, there were 2109 gastric cancer deaths in Xining, 1543 in males and 566 in females. There were 1185 cases in villages and 924 in cities. Male mortality (16.64/100,000) was higher than female (6.42/100,000). The mortality rate in rural areas (20.40/100,000) was higher than in urban areas (7.62/100,000). CONCLUSION: Overall morbidity and mortality rates of gastric cancer are on the rise in Xining. Male morbidity and mortality rates are higher than female ones, and rural areas are higher than urban areas. AJTR
