肝细胞癌(Hepatocellular carcinoma,HCC)(简称肝癌)是世界第五大常见肿瘤,位列世界第三位的癌症死亡原因[1]。在我国肝癌的死亡率位居恶性肿瘤中死亡率的第二位。目前已知乙(Hepatitis B Virus, HBV)、丙(Hepatitis C Virus, HCV)型肝炎病毒感染、酗酒、暴露于黄曲霉素是HCC发病的高危因素。但其主要死亡原因归咎于肝内转移(包括门静脉癌栓(PVTT)和肝内播散)。预防肝癌的死亡主要是阻止其发生侵袭、转移。肝癌的侵袭转移是多基因、多步骤、多阶段的过程且这些基因之间的关系密切相连。
HCC有一个显著的流行病学特点:肿瘤发生率的性别差异现象。男性的肝癌发病率普遍高于女性。地域的不同,男女的发病率也不同,在2:1-4:1之间,伴肝硬化的HCC男女发病率之比更是达到11:1。性别差异可能影响肝癌的发生发展。本课题组已建立二乙基亚硝胺(diethylnitrosamine, DEN)联合N-亚硝基吗啉(N-nitrosomorpholine, NMOR)诱发大鼠肝癌模型为典型炎症相关性肝癌模型。并且证实HCC发病率的性别差异现象,提示雌激素通过雌激素受...
【英文摘要】
Hepatocellular carcinoma (HCC) ranks as the fifth most common cancer around theworld and it is one of the major health problems worldwide. Also, HCC accounts for thethird leading cause of cancer-related deaths worldwide and the second in china. Whatwe know is that some factors are associated with an increased risk of development ofthe cancer, such as hepatitis B virus (HBV), hepatitis C virus (HCV), alcoholic abuse,and aflatoxin. But the major reason may be attributed to intra-hepatic metastasis thatinclude...
