雷帕霉素联合索拉非尼在超米兰标准肝移植肝细胞癌复发患者中的疗效观察

Therapeutic effect of rapamycin combined with sorafenib in hepatocellular carcinoma patients with tumor recurrence after liver transplantation beyond Milan criteria

目的观察雷帕霉素联合索拉非尼在超米兰标准的肝细胞癌肝移植术后复发患者中的疗效。方法回顾性分析2012年2月1日至2015年8月31日期间于天津市第一中心医院行经典非转流原位肝移植术且术后发生肿瘤复发的超米兰标准的41例肝细胞癌患者的临床资料,根据不同治疗方案分为局部治疗组(21例)和综合治疗组(20例),局部治疗包括手术切除、射频消融、经肝动脉介入化疗栓塞及放射性^(131)I粒子植入,综合治疗是指在局部治疗基础上加用雷帕霉素联合索拉非尼。结果局部治疗组治疗后疾病稳定12例、疾病进展9例,综合治疗组治疗后部分缓解2例、疾病稳定10例、疾病进展8例。局部治疗组和综合治疗组肿瘤复发后中位生存时间分别为9个月和12个月,复发后1年生存率分别为14%和55%,复发后2年生存率分别为0和15%,综合治疗组的生存曲线显示明显优于局部治疗组(P<0.01)。结论对超米兰标准肝细胞癌肝移植术后肿瘤复发患者采用雷帕霉素联合索拉非尼综合性治疗可显著提高复发患者的生存时间。

Objective To observe efficacy of rapamycin combined with sorafenib in hepatocellular carcinoma （HCC） patients with tumor recurrence after liver transplantation beyond Milan criteria. Methods Forty-one beyond Milan criteria HCC patients who underwent the classic orthotopic liver transplantation without bypass and the tumor postoperatively recurred in the Tianjin First Center Hospital from February 1, 2012 to August 31, 2015 were collected retrospectively, then were divided into a local treatment group （n=21） and a comprehensive treatment group （n=20）. The local treatment included the surgical resection, radiofrequency ablation, transcatheter arterial chemoembolization, radioactive seed implantation, etc.. The comprehensive treatment was on the basis of the local treatment plus rapamycin in combination with sorafenib. Results There were 12 patients with stable disease and 9 patients with progressive disease in the local treatment group. There were 12 patients with partial response, 10 patients with stable disease and 8 patients with progressive disease in the comprehensive group. In the local treatment group and the comprehensive treatment group, the median survival time were 9 months and 12 months, and the 1-year and 2-year survival rates after the recurrence were 14% versus 55%, 0 versus 15%, respectively. The survival of the comprehensive treatment group was significantly better than that of the local treatment group （P〈0.01）. Conclusion Combination of rapamycin and sorafenib in HCC patients with tumor recurrence after liver transplantation beyond Milan criteria can significantly improve survival time of patient with recurrence.
