Comparison of Liver diseases between Japan and China using Screenig of Ultrasonography

肝细胞癌（HCC）是亚洲的高发人群。为了降低本病的死亡率，日本推荐早期进行超声筛查诊断，但在中国还没有。本研究是暨南医学院与北京医科大学在高危人群中的联合研究，旨在通过超声筛查发现HCC。北京市市民体检18604例，高危组11284例，对照组4526例，随访组2254例。高危组10例（0.86%），门诊组97例（0.96%），对照组未见HCC发生。这些结果与日本的结果一致。超声引导穿刺55例以上进行病理诊断。在肝硬化慢性肝损害随访研究中，HCC发生率为1.2%（10/844例）。目前国内尚未建立HCC的早期诊断方法，本研究将为开展其他或更深入的研究提供依据。

Hepatocellular carcinoma (HCC) is known to be suffered high population in Asia. To reduce the death of this disease, early diagnosis by ultrasonic screening is recommended in Japan, but still not in China. This study is designed for ultrasonic screening to find HCC,as the co-research between Jichi Medical School and Beijing Medical University in high risk group. 18604 examinations were at the citizen in Beijing, the 11284 in high risk group, 4526 in control group, 2254 in follow up group. The HCC were found 10 cases (0.86%) in high risk group and 97cases (0.96%) in the out patient group, but not found in control group. These results were consistent with those in Japan. Ultrasonic guided puncture were in over 55 cases to identify the pathological diagnosis. The 1.2% (10/844 cases) of HCC were found in follow up study in chronic liver damage of liver cirrhosis. To establish of early diagnosis in HCC is yielded in China, and this study will be effective to make other or more advanced researches.
