Incidence and mortality of nasopharyngeal carcinoma in China, 2014 / 中华肿瘤杂志

ABSTRACT

Objective@#To estimate the incidence and mortality of nasopharyngeal carcinoma in China based on cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR).@*Methods@#449 cancer registries submitted nasopharyngeal carcinoma incidence and deaths occurred in 2014 to NCCR. After evaluating the data quality, 339 registries′ data were accepted for analysis and stratified by area (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of nasopharyngeal carcinoma were estimated. Chinese population census in 2000 and Segi′s population were used for age-standardized incidence and mortality rates.@*Results@#The estimates of new nasopharyngeal carcinoma incident cases and deaths were 44.6 thousands and 24.2 thousands, respectively. The crude incidence rate was 3.26/100 000 (Male 4.51/100 000, Female 1.94/100 000). Age-standardized incidence rates by Chinese standard population (ASIRC, 2000) and by world standard population (ASIRW) were 2.48/100 000 and 2.33/100 000, respectively. Male to female ratio was 2.32∶1. The ASIRC in urban and rural areas were all 2.48/100 000. The crude mortality rate of nasopharyngeal carcinoma was 1.77/100 000 (Male 2.55/100 000, Female 0.95/100 000). Age-standardized mortality rates by Chinese standard population (ASMRC, 2000) and by world standard population(ASMRW) were 1.23/100 000 and 1.20/100 000, respectively. The ASMRC in urban and rural areas were all 1.23/100 000. The cumulative incidence and mortality rates(0-74 years old)were 0.25% and 0.14%, respectively.@*Conclusions@#Incidence and mortality of nasopharyngeal carcinoma in China in 2014 were at high levels in the world. Corresponding prevention and control measures should be established according to the epidemic characteristics and risk factors of nasopharyngeal carcinoma.
