【摘要】：【目的】探索2004-2011年广东省四会市肝癌发病的空间分布模式,为四会市肝癌防控工作提供理论依据。【方法】利用Sa TScan 9.4.4计算时空扫描统计量,对2004-2011年四会市各乡镇肝癌的发病率进行空间分析,并结合地理信息系统(Arc GIS 10.2)实现分析结果的可视化。【结果】2004-2011年广东省四会市肝癌累计发病1252例,发病率总体呈上升趋势,波动范围为32.67/10万~41.14/10万。空间扫描发现肝癌发病存在聚集性,结果显示总人群肝癌发病率高发性聚集区主要位于四会市南部及东南部地区,包括东城街道、大沙镇和龙甫镇(似然比LLR=6.34,P=0.019,相对危险度RR=1.31);低聚集区集中于中部偏北地区,包括罗源镇、地豆镇和江谷镇(LLR=8.66,P=0.001,RR=0.67)。男性扫描结果与总人群聚集结果一致,高发聚集区包括东城街道等3个地区(LLR=5.83,P=0.025,RR=1.33);低发聚集区包括罗源镇等3个地区(LLR=7.65,P=0.004,RR=0.65);女性扫描结果显示一个高聚集区,共包括大沙镇、东城、城中和贞山街道以及龙甫镇(LLR=5.18,P=0.043,RR=1.41)。【结论】四会市肝癌发病呈持续上升趋势,并存在明显的空间聚集性,提示应进一步探索相关地区肝癌的危险因素,加强其肝癌防治。
[Abstract]:[objective] to explore the spatial distribution pattern of liver cancer in Sihui City, Guangdong Province from 2004 to 2011, and to provide a theoretical basis for the prevention and control of liver cancer in Sihui City. [methods] the space-time scanning statistics were calculated by using sa TScan 9.4.4. The incidence of liver cancer in various towns of Sihui City from 2004 to 2011 was analyzed in space, and the results were visualized by Arc GIS 10.2. [results] 1252 cases of liver cancer occurred in Sihui City, Guangdong Province, from 2004 to 2011, and the incidence rate showed an overall upward trend. The range is 32.67 / 100, 000, 411.4 / 100, 000. Spatial scanning showed that the incidence of liver cancer was clustered. The results showed that the high incidence of liver cancer in the general population was mainly located in the south and southeast of Sihui city, including the streets of Dongcheng. Dasha Town and Longfu Town (likelihood ratio of LLRN 6.34PU 0.019, relative risk RRN 1.31), low concentration areas are concentrated in north-central areas, including Luoyuan Town, Didou Town and Jianggu Town (LLRRM8.66 PU 0.001 RRR0.67). The results of male scans were consistent with those of the general crowd. The high incidence areas included three areas, including the Dongcheng Street (LLRX 5.83), the low incidence areas included Luoyuan Town (LLRR 7.65, P0. 004), and the female scan showed a high concentration area, including Dasha Town, East City, and so on. [conclusion] the incidence of liver cancer in Sihui City is on the rise, and there is obvious spatial aggregation. It is suggested that the risk factors of liver cancer should be further explored and the prevention and treatment of liver cancer should be strengthened.
