We aimed to use the national cancer registration data in 2011 to estimate the incidence and mortality of laryngeal cancer within China. Methods： Comparable, high-quality data from 177 population-based cancer registries were qualified for analysis. The pooled data were stratified by area, sex and age group. National new cases and deaths of laryngeal cancer were estimated using age-specific rates and national population in 2010. All incidence and death rates were age-standardized to the 2000 Chinese standard population and Segi＇s population, which were expressed per 100,000 populations. Results： All 177 cancer registries covered a total of 175,310,169 population （98,341,507 in urban and 76,968,662 in rural areas）, accounting for 13.01% of the national population. The data quality indicators of proportion of morphological verification （MV%）, percentage of cancer cases identified with death certification only （DCO%） and mortality to incidence ratio （Mr/） were 77.98%, 2.62% and 0.55, respectively. Estimated 20,875 new cases of laryngeal cancer were diagnosed and 11,488 deaths from laryngeal cancer occurred in China in 2011. The crude incidence rate of laryngeal cancer was 1.55/100,000 （2.69/100,000 in males and 0.35/100,000 in females）. Age-standardized incidence rates by Chinese standard population （ASIRC） and by world standard population （ASIRW） were 1.13/100,000 and 1.14/100,000, respectively. Laryngeal cancer is much rarer in females than in males. The incidence rate was higher in urban areas than that in rural areas. The crude mortality rate of laryngeal cancer was 0.85/100,000 （1.42/100,000 in males and 0.25/100,000 in females）. Age-standardized mortality rates by Chinese standard population （ASMRC） and by world standard population （ASMRW） were both 0.61/100,000. The mortality rate in males was much higher than that in females. There was no definite difference in mortality rates of laryngeal cancer between urban and rural areas. Conclusions： Larynx is a specialized area and cancer of larynx significantly affects the quality of life for the patients. Comprehensive measures should be carried out to prevent the ascent of laryngeal cancer.展开更多

The crude incidence and mortality rates of TC were calculated by area(urban/rural), region(eastern, middle, western), gender and age group(0, 1-4, 5-9,…, 85+). China census in 2000 and world Segi's population were applied for age-standardized rates. Joinpoint(Version 4.6.0.0) model was used for time-trend analysis.Results: The crude incidence rate of TC was 7.56/100,000 which ranked the seventh in overall cancers. The agestandardized incidence rates by China population(ASIRC) and by World population(ASIRW) were 6.25/100,000 and 5.52/100,000, respectively. The crude mortality of TC in China was 0.52/100,000. The age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were0.34/100,000 and 0.32/100,000, respectively. Incidence and mortality rates of TC were higher in females than in males and higher in urban areas than in rural areas. Eastern areas had the highest incidence followed by middle and western areas. TC incidence increased dramatically after age of 15 years, then peaked at 14.08/100,000 in the group of 50-54 years and finally decreased sharply after 55 years old. TC mortality increased with age in population,reaching the peak of 5.09/100,000 in sub-population aged 85 years or older. TC incidence increased by 4.73 times from 2.40/100,000 in 2003 to 13.75/100,000 in 2012 with an average annual increase of 20%, while TC mortality only increased slightly around 0.32/100,000 from 0.26/100,000 to 0.36/100,000.Conclusions: Appropriate targeted prevention, early detection and treatment programs can be carried out to curb the rapid growth trend of TC and control the disease burden.展开更多
