中国鼻咽癌流行概况

Nasopharynx Cancer Epidemiology in China

通过国际癌症研究所(IARC)发布的全球鼻咽癌数据库,获取中国及世界部分其它地区或国家的鼻咽癌发病、死亡数据库,分析比较中国与全球不同地区的鼻咽癌流行情况,了解中国与全球其他地区的鼻咽癌负担情况。研究发现,中国鼻咽癌分别占全球鼻咽癌发病和死亡的38.29%和40.14%,发病率和死亡率高于世界平均水平(1.2/10万,0.7/10万),分别位列发病和死亡顺位的第18位和23位,且男性高于女性。中国的鼻咽癌发病以青壮年人口为主,死亡以中老年人口为主,但发病率和死亡率都是在老年人口(65岁以上)相对较高。鼻咽癌预后相对较差,生存率相对较低,我国鼻咽癌负担相对较重,应该在该人群中积极开展鼻咽癌筛查和诊治工作,同时鉴于鼻咽癌的地域性发病差异,应该在我国两广地区加强鼻咽癌的防控工作。

Analysis and comparison of the nasopharynx cancer burden in China and other regions of the world with using incidence and mortality rates,which obtain from the global cancer database published by the International Agency for Research on Cancer（IARC）. It was found that both nasopharynx cancer incidence and mortality in China account for 38.29% and 40.14% of global nasopharynx cancer,respectively,with a high level of incidence and mortality（1.9/105 and 1.2/105）,which ranked as 18 and 23 in the word,respectively. Incidence and mortality of nasopharynx cancer are higher for male than for female. The number of new cases of nasopharynx cancer in China is relatively large in the young and middle aged,and the number of deaths is relatively large in the middle-aged and aged,but the incidence and mortality of nasopharynx cancer are both relatively high in old group over 65 years of age. The burden of nasopharynx is relatively large in China,with a relatively bad prognosis and a low level of survival rate,and this suggested that the screening should start actively among the high risk group of nasopharynx cancer,especially in Guangdong and Guangxi province in China.
