ABSTRACT

Objective To analyze the patterns of incidence and mortality on larynx cancer in China.Methods Data from 32 Cancer Registries in China were examined,sorted,and analyzed by the National Cancer Registry,to obtain the crude,Chinese national and world age- standardized rates (ASR) of incidence and mortality and their trends.Results The crude incidence and mortality rates of larynx cancer wcrc 2.04/105 and 1.06/105 in China during 2003-2007.The rates were higher in males than those in females,and also higher in urban areas than those in rural areas.The highest Chinese ASRs of incidence and mortality of larynx cancer in 32 cancer registries in China were 2.08/105 in Zhongshan city,Guangdong province,and 1.58/105 in She county,Hebei province respectively.The trend of incidence and mortality of larynx cancer was stable from 2003 to 2007.Conclusion Although both the incidence and mortality of larynx cancer in China were still in low level,comprehensive measures should be carried out to prevent the increase on both the incidence and mortality of larynx cancer.
