Objective This study aimed to examine temporal trends in all cancer-eliminated life expectancy and potential years of life lost (PYLL) in Kunshan city, Jiangsu province, between 1981 and 2015. Methods Data were collected from the vital records of Kunshan city. Cancer-eliminated life expectancy and PYLL were calculated by sex,and the Chinese population from the year 2000 was used to calculate age-standardized PYLL. Estimated annual percentage changes (APC) and 95% confidence intervals (CI) were used to examine temporal trends in increased cancer-eliminated life expectancy. Results Between 1981 and 2015,there was a significant decrease in age-standardized PYLL among males (APC=-2.31%, 95% CI:-2.51% to-2.11%) and females (APC=-1.91%, 95% CI:-2.26% to-1.56%). However, an increase was found in cancer-eliminated life expectancy in males and females, from 3.23 to 4.72 years in males(APC=2.42%,95% CI:1.64% to 3.20%)and from 1.10 to 2.94 years in females(APC=3.91%, 95% CI: 1.78% to 6.04%). Conclusion An overall decrease in age-standardized PYLL was observed when all cancers were considered,and an increase in cancer-eliminated life expectancy was found, suggesting that premature deaths due to cancers were reduced gradually. However, the negative effects of cancer on the health of the whole population have not been fully alleviated.

Objective To explore the temporal trend of cancer death rates in different age and the influencing factors in Kunshan,Jiangsu province,1981 to 2015.Methods Data were derived from cancer rcgistry and vital registration system.The Chinese age structure in 2000 was used to calculate age-standardized death rates (ASR),and annual percentage changes (APC) and 95% confidence interval (Cl) were used to estimate the temporal trend of cancer death rates.Difference decomposition method was applied to analyze the contribution of demographic and non-demographic factors for the change of cancer mortality.Results Between 1981 and 2015,the age standardized all cancers death rate decreased from 162.49 to 93.74 per 100,000 (APC=-l.6%,95% CI:-1.8%--1.5%).However,the ASR for those aged 70 years or above was stable over time (APC=0.2%,95% CI:-0.2%-0.5%),whereas aged 30-69 years was decreased from 240.01 in 1981 to 93.28 in 2015 (APC=-2.8%,95% CI:-3.0%--2.6%).In addition,the proportion of leading cancers were changed obviously.The proportion of lung cancer increased from 1981 to 2015,while gastric cancer,liver cancer,esophageal cancer and colorectal cancer decreased.Compared with the crude cancer mortality in 1993,the effect of the demographic and non-demographic factors to the increased death rate in 2015 were 308.93% and-208.93%,respectively.Conclusion The ASR death rate of all cancers was decreasing,and the rate in those aged 30 to 69 years decreased significantly,whereas stable in those aged 70 years or above.The effect of demographic characteristics on cancer mortality was significantly greater than that of non-demographic characteristics.
