Epidemiological characteristics and trends of cancer deaths among the residents in Huixian of Henan,2004-2020
Objective To explore the epidemiological characteristics and trends of cancer deaths among the residents in Huixian,so as to provide evidence for cancer prevention and control strategies.Methods The cancer mortality data were collected among the residents in Huixian from 2004-2020,and the mortality rate,standardization mortality,rank and composition of death causes were calculated;a log-linear equation was established to calculate average annual percent change(AAPC)and analyze the trend of cancer mortality.Results From 2004 to 2020,a total of 20 838 residents in Huixian died of cancer,with an average annual crude mortality rate of 145.16/105 and a standardized mortality rate of 139.32/105,ranked second in the death causes.The crude and standardized mortality rates of cancer in males were 180.06/105 and 165.10/105 respectively,and that in females was 109.65/105 and 100.27/105 respectively;the top five causes of death of cancer were esophageal cancer,gastric cancer,liver cancer,lung cancer and colorectal cancer,accounting for 82.08％of the total cancer deaths.The standardized mortality rate of cancer decreased from 2004-2020(APCC=-2.97％,t=-6.323,P＜0.05).The average annual declining rates for esophageal cancer,gastric cancer,and liver cancer were 5.90％,4.72％,and 3.50％respectively(t-values were-9.332,-8.321 and-6.971,respectively,and all P＜0.05),the average annual increasing rate for lung cancer,colorectal cancer and brain cancer were 2.29％,1.99％,and 7.20％respectively(t-values were 4.086,2.642 and 3.970,respectively,and all P＜0.05).The first cause of cancer deaths was different in different age groups,which was leukemia for 0-＜15 year-old group,liver cancer for 15-＜45 year-old group and esophageal cancer for the group aged 45 years or older.Conclusions Although the mortality rate of cancer among the residents in Huixian city showed a decreasing trend from 2004 to 2020,it remains the leading cause of death for the residents in Huixian city.It needs to strengthen the prevention and treatment of esophageal and gastric cancer and focus on lung cancer,colorectal cancer,brain cancer,etc.Different measures for the prevention and treatment of cancer should be taken for different age groups.
