2000～2004年广东省中山市恶性肿瘤发病地区差异

Regional Difference of Cancer Incidence in 2000 ～2004 in Zhongshan City,Guangdong Province

[目的]分析广东省中山市2000～2004年恶性肿瘤发病地区差异。[方法]收集、整理中山市肿瘤登记处2000～2004年恶性肿瘤的发病资料,统计分析不同地区恶性肿瘤的发病数、粗率、中国和世界人口标化率、构成比和年龄别发病率等指标。[结果]中山市2000～2004年恶性肿瘤发病男性主要以东区、石岐区为代表的中部地区和以黄圃、小榄镇为代表的北部地区发病水平较高,女性主要以东区、石岐区为代表的中部地区发病水平较高,而神湾、坦州、横栏和民众等沙田地区男女发病水平均较低。男性恶性肿瘤世界人口标化发病率最高地区(黄圃镇250.26/10万)是最低地区(横栏镇131.07/10万)的1.91倍,女性最高(石岐区177.79/10万)是最低地区(坦州镇76.67/10万)的2.32倍。此外,不同镇区高发恶性肿瘤也明显不同。[结论]2000～2004年中山市恶性肿瘤发病存在着明显的地区差异,提示中山市不同地区恶性肿瘤危害程度和发病因素不同,应针对性的开展恶性肿瘤防治工作。

[Purpose] To analyze the regional difference of cancer incidence from 2000 to 2004 in Zhongshan city.[Methods] Cancer incidence data of Zhongshan city in 2000～2004 from Zhongshan Cancer Registry were collected and collated.The numbers of new cases,incidence rate,agestandardized rates and age-specific incidence rate were calculated and analyzed.[Results] The areas with higher cancer incidence for male in 2000～2004 in Zhongshan were central region such as Dongqu and Shiqi districts and northern region such as Huangpu and Xiaolan town,and for that female were the central region such as Dongqu and Shiqi districts.The areas with lower incidence were tidal flat areas such as Shengwan,Tanzhou,Henglan and Mingzhong towns for both gender.The male highest cancer world standardized incidence rate（Huangpu town,250.26/105） was 1.91 times of lowest（Henglan town,131.07/105）,and the female highest cancer incidence rate（Shiqi district,177.79/105） was 2.32 times of lowest（Tanzhou town,76.67/105） in 2000～2004 in Zhongshan.Moreover,cancers with high incidence rates were quite different in different areas of Zhongshan during the period.[Conclusions] There are significant regional differences of cancer incidence in Zhongshan in 2000～2004.It suggests that cancer hazard and causes varied in different Zhongshan areas,hence cancer prevention and control should be carried out accordingly.
