Epidemiological analysis of cancer deaths in Shouguang city from 2018 to 2022
Objective To analyze malignant tumor death data in Shouguang city of Shandong province from 2018 to 2022,and to grasp its trend.Methods The data on malignant tumor deaths of residents in Shouguang city,Shandong province from 2018 to 2022 was collected to calculate crude mortality,standardized mortality and composition ratio,and to analyze the trend of malignant tumor changes.Results A total of 41 049 deaths were recorded among residents of Shouguang city,Shandong province in 2018 to 2022,with a mortality rate of 730.18/105.Cardiovascular and cerebrovascular diseases ranked first in the list of causes of death,malignant tumors ranked second,and respiratory diseases ranked third.There was a statistically significant difference in the comparison of male and female crude mortality rates in all years(x2 was 165.50,157.58,143.22,123.84,147.20,respectively,P＜0.01).Lung cancer ranked first in the death order for both males and females.Crude mortality rates for lung,stomach,liver,colorectal,esophageal,leukemia,and bladder cancers were higher for men than for women(x2 was 486.73,269.51,196.57,13.64,132.32,6.90,64.96,P＜0.01).The crude mor-tality rate for pancreatic cancer was slightly higher in men than in women(x2 was 3.84,P＜0.05).The crude mortality rates of bladder,esophagus,stomach,liver,and lung cancers in men were 6.03,3.23,2.61,2.24,and 2.06 times higher than those in women,respectively.With the increase of age,the mortality of male and female malignant tumors showed an obvious upward trend.The difference in the standardized mortality rate between men and women in the＜50 age group was not statistically significant(x2 was 0.28,0.4,1.61,2.22,0.91,3.19,0.5,0.09,1.47,respectively,all P＞0.01),and the difference in the standardized mortality rate between men and women in the＞50 age group was statistically significant(x2was 31.4,59.46,142.11,244.96,339.92,231.94,148.93,85.29,respectively,all P＜0.01).There were 9 940 deaths from malignant tumors in the age group＞50 years,constituting a ratio of 94.07％.The mortality rate of ma-lignant tumors in Shouguang City was in the order of city center,southern,western,northern,and eastern regions from low to high,and the differences between the city center and the 4 regions were all statistically significant(x2 was 146.08,174.66,271.95,and 418.15,respectively,P＜0.01).Conclusion From 2018 to 2022,the crude death rate of malig-nant tumors in Shouguang residents fluctuated slightly,and the standardized death rate decreased,males had a higher mor-tality rate than females.It is necessary to focus on the northern and eastern regions and men over 50 years old.
