摘要:
目的 评价二乙基亚硝胺(DEN)口服诱导的大鼠肝癌模型的病理学特性及其在经导管动脉化疗栓塞术(TACE)中的应用价值。方法 60只Sprague-Dawley(SD)大鼠口服0.01% DEN诱导原位肝癌,分为肿瘤模型组(n=40)和TACE应用组(n=20)。肿瘤模型组大鼠自诱导后第6周开始每周行肝脏MRI检查,肝脏出现0.2 cm、0.5 cm结节时分别随机处死5只大鼠,行肝脏大体观、苏木精-伊红(HE)及Masson染色检查;其余大鼠继续每周行肝脏MR及每2周肺部CT检查,观察肿瘤生长、转移,并记录大鼠生存时间。TACE应用组大鼠采用开腹经胃十二指肠动脉逆行插管行介入操作,记录技术成功率和死亡率;术后3 d、7 d分别处死大鼠,检测肿瘤坏死。结果 肿瘤模型组大鼠肿瘤结节直径达0.2 cm的中位诱导时间为8(7,10)周,肝脏体积增大,肿瘤呈灰白色微小结节;HE染色显示肝实质炎性细胞浸润,部分假小叶形成,肿瘤细胞核肥大深染;Masson染色显示少量胶原纤维。肿瘤结节直径达0.5 cm的中位诱导时间为11(10,12)周,肝脏体积缩小,表面有大量结节;HE染色可见假小叶形成;Masson染色显示胶原纤维增多。部分大鼠出现肝外转移。中位生存时间为诱导后13(8,20)周。TACE应用组大鼠经DSA证实肿瘤为富血供;TACE技术成功为11/16,手术相关死亡为3/16;术后3 d、7 d肿瘤坏死率分别为(48.16±2.65)%、(50.36±2.92)%。 结论 DEN诱导的大鼠原位肝癌较好地模仿了人类肝癌组织病理学特性,可用于TACE操作,是一种理想的介入治疗动物模型。
