Abstract:
Objective To analyze the mortality of upper gastrointestinal cancer in Cixian County, Hebei Province, China, over the past 33 years, and provide evidence for the prevention and treatment of such cancer.
Methods According to the cancer registration regulations, changes in the mortality of upper gastrointestinal cancer were collected, sorted and evaluated, and the trends in the mortality of upper gastrointestinal cancer were analyzed using the cancer registration data accumulated by the Cixian cancer Registration Office between January 1, 1983, and December 31, 2015. The percentage changes in crude mortality, standardized mortality in China, and the standardized worldwide mortality were calculated. The annual percent change of mortality was estimated using a linear regression model of the adjustment rate.
Results Over the 33-year period in Cixian County, the average crude mortality of upper gastrointestinal cancer was 119.31/100, 000, including 149.21/100, 000 for males and 88.40/100, 000 for females. The standardized mortality rate in China was 160.85/100, 000, including 227.00/100, 000 males and 108.07/100, 000 females. The worldwide standardized mortality rate was 162.39/100, 000, including 228.52/100, 000 males and 109.30/100, 000 females.
Conclusions The mortality of upper gastrointestinal cancer displayed a decreasing trend, but it still had the highest mortality rate of malignant tumors in Cixian County. Age-specific mortalities were increasing along with the rise of age.
