Abstract：Objective To analyze the changes in the incidence trend of malignant lymphoma and the impact of population aging on the incidence trend in Chonqing Municipality so as to put forward suggestions for malignant lymphoma prevention and control. Methods We collected new cases of malignant lymphoma reported by the cancer registration sites in Chongqing Municipality from 2006 to 2014. The indicators of malignant lymphoma such as incidence rate, age-standardized incidence rates by China and World population and annual percent change (APC) were calculated. The difference of incidence trend of malignant lymphoma was identified by curve estimated exponential distribution regression model. Difference decomposition method was used to estimate the contribution rates of population aging and other risk factors influencing the changes in incidence trend of malignant lymphoma. Results The incidence rate of malignant lymphoma in Chonqing Municipality increased from 2.31/100,000 in 2006 to 6.82/100,000 in 2014, and its APC was 9.09%, showing statistically significant differences in the incidence trend (P<0.05). The APCs of age-standardized incidence rates by China and World population were 5.34% and 4.92% respectively, showing no statistically signficant difference (both P>0.05). The rising of incidence rate of malignant lymphoma was affected by the coordination of population aging and other risk factors. The contribution rate of other risk factors was higher than that of population aging (72.45% vs. 27.55%). Conclusions The incidence rates of malignant lymphoma in Chongqing Municipality during 2006-2014 showed an increasing tendency. The rising of incidence rate of malignant lymphoma was influenced by the coordination of population aging and other risk factors. Special attention should be paid to primary prevention of malignant lymphoma.
