Background
There is a dearth of accurate information about patterns of mortality of lymphoid neoplasms and temporal trends in China. In this nationwide mortality study, we aimed to assess the mortality of lymphoma and myeloma in 2017 and the changes in the trend from 2004 to 2016.
Methods
Death certificate data obtained from the Chinese Center for Disease Control and Prevention’s disease surveillance points system (CDC-DSP) and population data from the National Bureau of Statistics of China were used in this study. We described the mortality of lymphoma and myeloma in 2017 by age group, sex, residence, and region and evaluated the temporal trend from 2004 to 2016 using joinpoint regression.
Results
An estimated 52,000 deaths associated with lymphoma and myeloma occurred in 2017. The age-standardized mortality rate China (ASMRC) and age-standardized mortality rate worldwide (ASMRW) per 100,000 were 3.74 and 2.60, respectively. Males had higher ASMRC than females (4.54 vs. 2.91 per 100,000). The ASMRC in urban areas was significantly higher than that in rural areas (4.35 vs. 3.47 per 100,000). The age-specific mortality rate showed an upward trend with age and reached a maximum in the age group of over 85 years. In terms of regional variation, Eastern China had the highest mortality rate (3.43/100,000), followed by Central China (3.10/100,000) and Western China (3.02/100,000). The mortality rates of lymphoma and myeloma increased annually by 4.5% during the period 2004–2016, with a significant rapid upward trend in rural areas since 2007.
Conclusions
The mortality of lymphoma and myeloma increased in China from 2004 to 2017. The rapid increase in disease burden in rural areas highlights new challenges for disease prevention and control strategies.
