Mortality Trends of Stomach Cancer in Qidong City, 1972—2016

Abstract

Objective To investigate the mortality trends of stomach cancer from 1972 to 2016 in Qidong, Jiangsu Province. Methods We collected and analyzed the mortality of stomach cancer in Qidong from 1972 to 2016 by gender and age from the cancer registry data. Statistics parameter included crude mortality rate(CR), China age-standardized rate(CASR), World age-standardized rate(WASR), truncated rate 35-64 year old, cumulative rate 0-74 year old, cumulative risk and annual percentage change(APC). Results There were 15863 stomach cancer deaths, accounting for 16.04% of all cancer deaths. The CR, CASR and WASR were 31.37/105, 21.66/105 and 21.39/105, respectively. The truncated rate 35-64 year old, cumulative rate 0-74 year old and cumulative risk were 28.86/105, 2.54% and 2.51%, respectively. CR, CASR and WASR were 40.53/105, 28.52/105 and 30.13/105 for 10 114 male cancer deaths and 22.45/105, 15.21/105 and 13.92/105 for 5749 female cancer deaths, respectively. The age-specific mortality curve showed that the mortality rate increased with age, and the peak age groups of male and female mortality were both the ≥80-year-old group, which were 365.44/105 and 185.26/105, respectively. The 45-year APC values of CR, CASR and WASR for gastric cancer were 0.55% (male: 0.56%, female: 0.50%), -2.08% (male: -2.29%, female: -1.91%) and -2.12% (male: -2.23%, female: -2.02%) (all P < 0.05). Conclusion Although the standardized mortality of gastric cancer in Qidong from 1972 to 2016 is gradually decreasing, the crude mortality is increasing. Effective prevention and control measures should be adopted according to local conditions.
