Abstract
Objective To analyze the incidence and changing trends of malignant tumors in Jiangyou city from 2018 to 2022.Methods Using the incidence data of malignant tumors in Jiangyou city from 2018 to 2022,indicators such as annual incidence rate,age-specific incidence rate,composition ratio,and incidence rank-ing of malignant tumors were calculated respectively.Results From 2018 to 2022,the average annual crude incidence rate of malignant tumors was 439.00/100 000,and the standardized incidence rate was 371.72/100 000.The average annual incidence rate of malignant tumors in males was significantly higher than that in fe-males,with a statistically significant difference(χ2=94.413,P<0.001).From 2018 to 2022,the incidence rates of malignant tumors increased to varying degrees in the total population(χ2trend=42.913,P<0.001),males(χ2trend=12.222,P<0.001),and females(χ2trend=41.325,P<0.001),and decreased after 2021;however,the incidence rate in males remained at a relatively high level.The incidence rates of malignant tumors in-creased with age in males(χ2trend=1 907.160,P<0.001),females(χ2trend=880.351,P<0.001),and the total population(χ2trend=2 371.567,P<0.001).From 2018 to 2022,the top five malignant tumors in terms of inci-dence ranking were lung cancer,colorectal cancer,liver cancer,gastric cancer,and esophageal cancer,account-ing for 63.04%of the total incidence.The incidence rates of lung cancer,colorectal cancer,liver cancer,gastric cancer,esophageal cancer,breast cancer,prostate cancer,and cervical cancer increased with age in males,fe-males,and the total population(P<0.05).Conclusion From 2018 to 2022,the incidence rate of malignant tumors in Jiangyou showed an upward trend.Among them,lung cancer,colorectal cancer,liver cancer,gastric cancer,and esophageal cancer had relatively high incidence rates.The population aged over 40 years is a high-risk group,especially males,who require focused attention and prevention.关键词
