Cholangiocarcinoma (CCA) is a serious public health problem in the Northeast of Thailand. CCA is considered to be an incurable and rapidly lethal disease. Knowledge of the distribution of CCA patients is necessary for management strategies.
This study aimed to utilize the Geographic Information System and Google EarthTM for distribution mapping of cholangiocarcinoma in Satuek District, Buriram, Thailand, during a 5-year period (2008-2012).
In this retrospective study data were collected and reviewed from the OPD cards, definitive cases of CCA were patients who were treated in Satuek hospital and were diagnosed with CCA or ICD-10 code C22.1. CCA cases were used to analyze and calculate with ArcGIS 9.2, all of data were imported into Google Earth using the online web page www.earthpoint.us. Data were displayed at village points.
A total of 53 cases were diagnosed and identified as CCA. The incidence was 53.57 per 100,000 population (65.5 for males and 30.8 for females) and the majority of CCA cases were in stages IV and IIA. The average age was 67 years old. The highest attack rate was observed in Thung Wang sub-district (161.4 per 100,000 population). The map display at village points for CCA patients based on Google Earth gave a clear visual deistribution.
CCA is still a major problem in Satuek district, Buriram province of Thailand. The Google Earth production process is very simple and easy to learn. It is suitable for the use in further development of CCA management strategies.
胆管癌（CCA）是泰国东北部一个严重的公共卫生问题。CCA被认为是一种无法治愈且致死率高的疾病。了解CCA患者的分布情况对于管理策略至关重要。
本研究旨在利用地理信息系统和谷歌地球（Google EarthTM）绘制泰国武里南府沙图克区5年期间（2008 - 2012年）胆管癌的分布图。
在这项回顾性研究中，数据收集自门诊病历卡并进行审核，CCA确诊病例为在沙图克医院接受治疗且被诊断为CCA或国际疾病分类第十版（ICD - 10）编码为C22.1的患者。使用ArcGIS 9.2对CCA病例进行分析和计算，所有数据通过在线网页www.earthpoint.us导入谷歌地球。数据显示在村庄点上。
共诊断出53例CCA病例。发病率为每10万人53.57例（男性为65.5例，女性为30.8例），大多数CCA病例处于IV期和IIA期。平均年龄为67岁。通旺分区的发病率最高（每10万人161.4例）。基于谷歌地球的CCA患者村庄点地图展示呈现出清晰的可视化分布。
在泰国武里南府沙图克区，CCA仍然是一个主要问题。谷歌地球制作过程非常简单且易于学习。它适用于CCA管理策略进一步发展中的应用。
