2003-2007年中国肿瘤登记地区白血病发病与死亡分析

目的:描述中国肿瘤登记地区2003-2007年白血病的发病与死亡水平,并进行国际间比较.方法:对全国32个肿瘤登记地区的数据进行汇总,计算白血病的发病率和死亡率.结果:全国肿瘤登记地区白血病发病率为5.17/10万,城市地区高于农村地区;在恶性肿瘤新发病例构成中位居第13位,占全部恶性肿瘤的1.94％；髓样白血病发病率高于淋巴样白血病.32个肿瘤登记地区白血病死亡率为3.94/10万,白血病死亡位于死因的第9位,占全部恶性肿瘤死亡的2.29％.与1970年和1990年的数据比较,白血病死亡位次有明显下降,但粗死亡率仍然呈上升趋势.中国男、女性白血病发病率在统计的184个国家中均位居第87位.结论:白血病是危害中国居民的主要恶性肿瘤之一.

Analysis of incidence and mortality of leukemia in registration areas of China from 2003 to 2007

Objective: To describe the incidence and mortality rates of leukemia in cancer registration areas of China from 2003 to 2007 and explore the international variation. Methods: The pooled data from 32 cancer registries in China from 2003 to 2007 were collected, and the incidence and mortality rates of leukemia were calculated. Results: The overall incidence rate of leukemia in 32 registration areas was 5.17/100 000, constituting 1.94% of all tumors and ranked as the thirteen common cancer in China. The incidence rate of leukemia in urban areas was higher than that in rural areas. The incidence rate of myeloid leukemia was higher than that of lymphoid leukemia. The overall mortality rate of leukemia in 32 registration areas was 3.94/100 000, and leukemia ranked as the ninth most common cancer and constituted 2.29% of all malignant tumors. Compared with the data of 1970 and 1990, the ranking of leukemia dropped, but the crude mortality rate was still increased. The incidence rates of leukemia ranked 87th both in males and females in China among 184 countries. Conclusion: Leukemia is one of the most common life-threatening cancers in China.
