中国2003—2007年喉癌发病率和死亡率分析

Incidence and mortality of larynx cancer in China during 2003-2007

目的研究中国喉癌发病与死亡的流行状况。方法2003--2007年喉癌发病与死亡数据来源于全国32个肿瘤登记地区，并经全国肿瘤登记中心审核、整理和统计分析，计算粗率、中国和世界标化率及变化趋势。结果2003--2007年中国喉癌粗发病率为2．04／10万，粗死亡率为1．06／10万，均为男性高于女性，城市高于农村；在32个登记地区中发病中标率最高是广东省中山市（2．08／10万），死亡中标率最高是河北省涉县（1．58／10万）；2003--2007年全国喉癌发病率和死亡率变动不大。结论中国喉癌发病率、死亡率处于较低水平，但应采取综合措施，防止喉癌发病率和死亡率上升。

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 were 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.
