Mortality and life lost due to lung cancer among Longyou residents / 预防医学

ABSTRACT

Objective To learn the mortality and trend of lung cancer among Longyou residents, and to provide scientific basis for comprehensive prevention and control of lung cancer. Methods Data from the surveillance of lung cancer mortality among Longyou residents from 2010 to 2016 were collected. Crude mortality rate, standardized mortality rate of lung cancer (standardized by the 2010 national census data), potential years of life lost rate (PYLLR) and standard potential years of life lost rate (SPYLLR) were calculated. Descriptive analysis was conducted in the gender, age distribution and potential life loss caused by lung cancer. Results From 2010 to 2016, there were 1555 cases of lung cancer in Longyou County, with a mortality rate of 48.17/100000 and a standardized mortality rate of 38.05/100000, ranking first among the deaths of malignant tumors.The mortality rate of lung cancer increased year by year (P<0.01) .The annual mortality rate of males lung cancer was 72.05/ 100000, higher than that of females (P<0.001) .The mortality rate of males with lung cancer increased year by year (P<0.01), with an average annual growth rate of 4.69％. The annual growth rate of females with lung cancer mortality was 2.49％, but there was no significant increase (P>0.05) .Lung cancer mortality increased with age (P<0.001), of which 1243 cases died of lung cancer, accounting for 79.94％ of total lung cancer deaths. The potential life loss of lung cancer from 2010 to 2016 was 12471 person-years, with PYLLR of 4.41‰and SPYLLR of 3.72‰. The SPYLLR of males with lung cancer was 5.31‰ and that of females was 1.95‰. Conclusion The mortality rate of Lung cancer among residents in Longyou County has been increasing, which mainly endangers people over 60 years old. The mortality rate and PYLLR of males with lung cancer are higher than that of females.
