Trend of nasopharyngeal carcinoma mortality and years of life lost in China and Its Provinces from 2005 to 2020
Menée en Chine sur la période 2005-2020, cette étude analyse l'évolution de la mortalité par carcinome du rhinopharynx et des années de vie perdues en lien avec la maladie
To examine the trends of nasopharyngeal carcinoma (NPC) mortality and years of life lost (YLL) in China and its provinces from 2005 to 2020, our study used data from China National Mortality Surveillance System (NMSS) to estimate the number and rate of mortality and YLL of NPC by age and sex. We calculated average annual percent change (AAPC) to describe the trend of NPC mortality and YLL over time. We also analyzed the proportion of NPC deaths in all cancer deaths and explored the drivers of change in NPC deaths by decomposition analysis. The age-standardized mortality rate (ASMR) of NPC in China had a significant downward trend from 2.0/100,000 in 2005 to 1.4/100,000 in 2020 (AAPC = -2.4, P<0.05). Age-standardized YLL rate also showed the similar trends (AAPC = -2.8, P<0.05). Southern provinces including Guangdong (163.9/100,000), Guangxi (130.5/100,000), and Hainan (105.6/100,000) had the highest YLL rate in 2020. The mortality and YLL rate increased with age and males were higher than females. From 2005 to 2020, the proportion of NPC deaths in all cancer deaths remained stable at around 1.0% in China. The total number of deaths of NPC increased by 7.3%, of which age-specific mortality, population growth, and population aging accounted for -46.2%, 8.5% and 45.0%, respectively. NPC remains a significant public health issue in China southern provinces and tailored prevention and control strategies should be strengthened to reduce the burden of premature mortality of NPC in high risk areas.
