摘要:
【摘要】 目的 通过模拟原位膀胱癌发生机制构建兔VX2膀胱癌移植瘤动物模型,研究其生物学特性及影像学表现。方法 采用同轴法穿刺接种VX2细胞株于25只新西兰大白兔膀胱,接种术后14、21、28 d分别作CT平扫及增强扫描,评估肿瘤种植及生长情况。取兔膀胱组织标本作大体解剖学及组织病理学检查,同时观察腹腔淋巴结及肝肺转移情况。结果 22只实验兔建模成功,植瘤成瘤率为88.0%(22/25)。植瘤后14、21、28 d瘤体平均长径分别为(1.38±0.20) mm、(2.30±0.08) mm、(3.22±0.24) mm,且瘤体变化差异有显著统计学意义(P<0.01)。VX2移植瘤CT表现为膀胱壁局部不规则增厚或肿块突起,呈均匀强化(14 d)或环型强化(21、28 d),肿瘤腔内呈不同程度充盈缺损。种植瘤大体形态及其影像学特征基本相符,组织病理学表现为血管丰富的低分化鳞状细胞癌,呈浸润性生长,21 d后瘤体中心出现坏死,21、28 d出现肝、肺及腹腔淋巴结转移。结论 本研究成功构建兔VX2膀胱移植瘤模型,基本反映了膀胱癌发生与发展过程,适合CT动态观察及实验研究。
