摘 要:目的:评价生物反应调节剂(BRM)经肝动脉化疗栓塞术(TACE)治疗ACI大鼠肝细胞癌的疗效。方法:在30只雄性ACI大鼠肝包膜下植入Morris Hepatom 3924A肝癌瘤块(2 mm3),移植术后13天行MRI检查,测量肿瘤体积V1;第14天时,经腹部切开术及胃十二指肠动脉逆行插管而采取以下3种介入治疗方案:①A组,0.1 mg丝裂霉素、0.1 ml碘油、7.5μg TNFα和5×103IU IL-2(n=10);②B组,0.1 mg丝裂霉素、0.1 ml碘油、0.05 mg链球菌提取物(OK-432)和5×103IU IL-2(n=10);③C组(对照组),0.1 mg丝裂霉素、0.1 ml碘油(n=10);13天后再次行MRI检查以确定肿瘤体积V2变化。比较肝肿瘤体积生长率V2/V1。结果:肿瘤治疗前和治疗后体积分别为A组0.0377 cm3和0.2752 cm3;B组0.0344 cm3和0.2233 cm3;C组0.0380 cm3和0.3398 cm3。介入治疗后肿瘤体积与治疗前肿瘤体积之比(V2/V1)分别为A组7.31、B组6.53、C组9.14。与对照组相比,采取A组的治疗方案能抑制肝肿瘤体积的生长(P=0.042),采取B组的治疗方案能明显抑制肿瘤的生长(P=0.004)。结论:采取免疫化疗栓塞术能有效抑制ACI大鼠肝细胞癌的生长。Objective: To assess the value of biological response modifiers (BRM) such as tumor necrosis factor (TNFa) and OK 432 in transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) in ACI rats. Methods:A solid Morris Hepatoma 3924A (2 mm^3 ) was implanted into the liver of 30 male ACI rats. After laparotomy and retrograde placement of a microcatheter into the gastroduodenal artery, the following agents were injected into the hepatic artery (14 days after implantation):(A) Mitomycin (0.1 mg) + Lipiodol (0. 1 ml) + TNα(7.5μg) + IL-2 (5×10^3) (n=10); (B) Mitomycin (0. 1mg) + Lipiodol (0. 1 ml) ( OK-432 (0.05mg) + IL-2 (5×10^3) (n=10); (C) Mitomycin (0. 1mg) + Lipiodol (0. 1 ml) (n= 10,control group). The tumor volumes before treatment (V1) and after treatment (V2) were determined by MRI and the tumor growth ratio (V2/V1) was calculated. Results:The mean tumor volumes of V1 and V2 were 0.0377 cm^3 and 0.2752 cm^3 in group A,0.0344 cm^3 and 0.2233 cm^3 in group B,0.0380 cm^3 and 0.3398 cm^3 in group C,respectively. The resulting mean ratios (V2/V1) were 7. 31 in group A,6.53 in group B and 9.14 in group C, respectively. Compared with group C (control group) ,groups A and B both showed significant inhibition of tumor growth within the period of observation (P= 0.042 and 0.004, respectively). Conclusion.. The growth of HCC can be obviously inhibited by utilizing the combined transarterial immuno chemoembolization therapy in ACI rats.
