Abstract:
Objective To analyze the mortality trend of malignant tumors and the early death and life reduction levels of residents in Lanzhou from 2014 to 2022,so as to provide a basis for the prevention and control of malignant tumors.Methods The mortality data of malignant tumors of residents in Lanzhou from 2014 to 2022 were collected,and the crude mortality rate,standardized mortality rate,early death probability,potential life loss years(PYLL),life reduction rate(PYLLR)and annual percentage of change(APC)were used to analyze the mortality trend of malignant tumors and early death and life reduction.Results From 2014 to 2022,the cumulative number of deaths from malignant tumors in Lanzhou residents was 21192,with an average crude mortality rate of 62.74/100000 and an annual standardized mortality rate of 55.30/100000.The mortality rate of malignant tumors in the three age groups of 0~14 years,15~64 years old and≥65 years old showed that the mortality rate was higher with the older age,and the mortality rate increased sharply in the≥65－year－old population,and the mortality rate of each age group showed a decreasing trend year by year,and it was statistically significant(P<0.05).The top 7 were lung cancer,gastric cancer,liver cancer,colorectal cancer,pancreatic cancer,esophageal cancer and breast cancer,except for breast cancer,the crude mortality rate of other diseases was higher in men than in women,and the difference in crude mortality between men and women was statistically significant(all P<0.01).From 2014 to 2022,the probability of early death of malignant tumors among residents aged 30~69 in Lanzhou was 2.94%,and its APC was －8.04%(P<0.05).From 2014 to 2022,the probability of premature death caused by lung cancer,gastric cancer,colorectal cancer,esophageal cancer and breast cancer among residents aged 30~69 in Lanzhou showed a downward trend,and the APCs were － 6.22%,－15.94%,－4.56%,－16.99%and －12.54%(P<0.05).The analysis of early death and life loss showed that the PYLL caused by malignant tumors accumulated 234141 person－years,of which 128727 person－years were male and 105413 person－years were female.The APC of PYLL was －5.92%(P<0.05).PYLLR was 6.97‰,7.47‰ for men and 6.45‰ for women.The APC of PYLLR was －6.71%(P<0.05).The trends of PYLL and PYLLR in men and women were statistically significant(P<0.05).Conclusion From 2014 to 2022,the probability of early death and disease burden of malignant tumors in Lanzhou showed a downward trend year by year.Lung cancer,gastric cancer,liver cancer and colorectal cancer are the main malignant tumors in Lanzhou City,which should be prevented and treated with priority,and the screening and detection of malignant tumors in the elderly population should be strengthened to reduce the burden of malignant tumors.
