目的:了解湖南省慢性淋巴细胞白血病(CLL)分布规律及流行病学特征。方法:按照国家肿瘤登记中心指定的审核方法和评价标准，共纳入24个肿瘤登记处上报的慢性淋巴细胞白血病登记数据。通过回顾性分析的研究方法，将入选的登记处数据按照年份、行政分区、城乡、性别、年龄分别计算发病率和死亡率并进行分析。结果:湖南省2014年—2015年新诊断CLL患者有104例，年均发病率为0.39/10万。2014年及2015年发病率分别为0.39/10万、0.39/10万；株洲市年均发病率为0.8/10万，在各地级市中发病率最高，长沙市开福区年均发病率为1.65/10万，在各区级行政区划中最高；城市发病率高于农村(城市vs农村，n P＝0.006)；男女性别发病率比为1.7∶1；患病病例主要集中在61~70岁人群，占患病病例总数的33.65%(35/104)；2014年—2015年CLL死亡患者有64例，年均死亡率为0.24/10万，2014年死亡率及2015年死亡率分别为0.22/10万、0.26/10万；衡阳市年均死亡率为0.53/10万，在各地级市中死亡率最高，长沙市芙蓉区年均死亡率为0.74/10万，在各区级行政区划中最高；城市死亡率高于农村，但差异无统计学意义(n P＝0.169)；男女性别死亡率比为1.4∶1；死亡病例主要集中在71~80岁人群，占死亡病例总数的29.69%(19/64)。n 结论:湖南省CLL发病率远低于欧美人群，主要发生在中老年人群，男性多见，城市发病率高于乡村，株洲市发病率最高。死亡CLL患者集中于中老年人群，男性较多；城市死亡率略高于农村；衡阳市死亡率最高。“,”Objective:To understand the distribution and epidemiological characteristics of chronic lymphocytic leukemia (CLL) in Hunan Province.Methods:According to the audit methods and evaluation criteria specified by the National Cancer Registration Center, the registration data of CLL reported by 24 tumor registries was included. Through the research method of retrospective analysis, the selected registry data was calculated and analyzed according to the year, administrative division, urban and rural areas, gender and age.Results:A total of 104 newly diagnosed CLL patients were diagnosed in Hunan Province from 2014 to 2015, with an average annual morbidity of 0.39/100, 000. The morbidity in 2014 and 2015 was 0.39/100, 000 and 0.39/100, 000, respectively. The annual average morbidity in Zhuzhou was 0.8/100, 000, which was the highest among municipalities. The annual average morbidity in Kaifu District of Changsha was 1.65/100, 000, which was the highest among district-level administrative divisions. The morbidity of urban was higher than that of rural (Urban vs Rural, n P=0.006). The male to female morbidity was 1.7∶1. The cases were mainly concentrated in the 61-70-year-old population, accounting for 33.65% of all cases (35/104). There were 64 patients died of CLL in Hunan Province from 2014 to 2015, and the average annual mortality was 0.24/100, 000. The mortality in 2014 and 2015 was 0.22/100, 000 and 0.26/100, 000, respectively. The average annual mortality in Hengyang was 0.53/100, 000, which was the highest among municipalities. The average annual mortality in Furong District of Changsha was 0.74/100, 000, which was the highest among district-level administrative divisions. The mortality of urban was higher than that of rural but with no significant difference (n P=0.006). The male to female mortality rate was 1.4∶1. The deaths were mainly concentrated in the 71-80-year-old population, accounting for 29.69% of all deaths (19/64).n Conclusions:The morbidity of CLL in Hunan Province is much lower than that of European and American populations, and it mainly occurs in the elderly people. It is more common in men. The morbidity of urban is higher than that of rural and morbidity in Zhuzhou is the highest. The death of CLL patients was mainly in middle-aged and elderly population, with more males. The mortality of urban is slightly higher than that of rural and the mortality in Hengyang is the highest.
