江苏省启东县是我国及世界上人类原发性肝癌高发地区之一。为了从多种途径探索人类肝癌的致癌因素,我们对启东的几种动物肝癌进行了调查,发现启东县的鸭子肝癌比较多,其流行情况和启东县人类肝癌在地理分布上有相似之处,这一情况对人类肝癌病因的深入研究可能有所启示。现将启东县鸭子肝癌的流行情况、病理形态和病因的初步分析报告如下。 Qidong County, Jiangsu Province is one of the regions with high prevalence of human primary liver cancer in China and the world. In order to explore the carcinogenic factors of human liver cancer from various sources, we investigated several animal liver cancers in Qidong County and found that there were many duck liver cancers in Qidong County. The epidemic situation was similar to that of human liver cancer in Qidong County. This situation may have implications for the in-depth study of the cause of human liver cancer. The preliminary analysis of the prevalence, pathology and etiology of liver cancer in ducks in Qidong County is reported below.
