摘要: 目的 描述中国肿瘤登记地区2008-2012年脑及神经系统肿瘤发病与死亡水平。方法 对全国135个肿瘤登记处的数据进行汇总,计算脑及神经系统肿瘤的发病率与死亡率。结果 2008-2012年全国肿瘤登记地区脑及神经系统肿瘤发病率为6.21/10万,中国人口标化率(以下简称中标率)为3.93/10万,世界人口标化率(以下简称世标率)为3.87/10万,占全部恶性肿瘤发病的2.19%,位居全部恶性肿瘤发病的第11位。男性发病率为9.45/10万(中标率为6.31/10万),女性发病率2.88/10万(中标率1.72/10万)。城市和农村地区,脑及神经系统肿瘤发病率分别为7.59/10万和4.07/10万(发病中标率分别为4.60/10万和2.78/10万)。2008-2012年,全国肿瘤登记地区脑及神经系统肿瘤死亡率为2.48/10万(中标率和世标率都为1.40/10万),在各种恶性肿瘤死亡原因中排列第12位。男性的死亡率为3.71/10万,女性为1.21/10万。城市和农村地区脑及神经系统肿瘤死亡率分别为2.91/10万和1.81/10万(中标死亡率分别为1.53/10万和1.16/10万)。结论 脑及神经系统肿瘤是危害中国居民主要恶性肿瘤之一,城市发病率高于农村,男性高于女性。应加强脑及神经系统肿瘤的预防与控制工作。Abstract: Objective To describe the incidence and mortality rates of brain and nervous system cancer in 135 cancer registration areas of China from 2008 to 2012. Methods The pooled data from 135 cancer registration areas in China from 2008 to 2012 were collected, and the incidence and mortality rates of brain and nervous system cancer were calculated. Results The overall incidence rate of brain and nervous system cancer in 135 registration areas was 6.21/100 000, and age-standardized rate by Chinese standard population (ASR China) and age-standardized rate by Segi's world population(ASR world) were 3.93/100 000 and 3.87/100 000 respectively, accounting for 2.19% of whole cancer and being ranked as the eleventh common cancer in China. The crude cancer incidence of brain and nervous system and ASR China were 9.45/100 000 and 6.31/100 000 for males compared with 2.88/100 000 and 1.72/100 000 for females, respectively. The brain and nervous system cancer incidence and ASR China were 7.59/100 000 and 4.60/100 000 in urban areas, while 4.07/100 000 and 2.78/100 000 in rural areas, respectively. The crude mortality in China was 2.48/100 000 (male 3.71/100 000, female 1.21/100 000), age-standardized mortality by Chinese standard population and by world standard population were both 1.40/100 000,and being ranked as the twelfth among the causes of death of various common cancer in China. The crude cancer mortality of brain and nervous system and ASR China were 2.91/100 000 and 1.53/100 000 in urban areas compared with 1.81/100 000 and 1.16/100 000 in rural areas, respectively. Conclusions Brain and nervous system cancer is one of the most common life-threatening cancers in China. The incidence rate of brain and nervous system cancer in urban areas is higher than that in rural areas of China, which is also higher in males than in females. The prevention and control for brain and nervous system cancer must be strengthened.
