大肝癌58例患者经肝动脉插管化疗栓塞降期治疗体会

目的 探讨大肝癌经肝动脉插管化疗栓塞降期治疗后,实施二期肝切除和肝脏移植手术的可行性.方法 回顾性分析2006年6月至2010年3月58例首次诊断为切除困难的大肝癌患者(直径＞5 cm),实施肝动脉插管化疗栓塞降期治疗后,分别实施肝移植术(36例),二期肝切除(22例).利用Kaplan-Meier法和COX风险比例模型计算累积总体生存率、无瘤生存率和影响预后的因素.结果 58例患者术后中位随访22个月,平均生存时间为(23.57±1.54)个月.肝移植组(36例)1、2、3年总体生存率(OS)、无瘤生存率(RFS)分别是94%、84%、73%和88%、75%、64%.肿瘤平均复发时间为(12.3±6.4)个月(3～23个月).其中28例患者降期至Milan标准,1、2、3年总体生存率和无瘤生存率优于非降期组(OS%%、88%、75%vs 92%、48%、48%P=0.067;RFS95%、95%、79%vs 76%、40%、40%P=0.002).肝切除组1、2、3年总体生存率、无瘤生存率分别为100%、64%、52%和72%、49%、49%,平均复发时间为(9.3±4.5)个月.经TACE肝移植组患者远期预后优于肝切除组(OS,P=0.178;RFS,P=0.139).多因素分析只有病理肿瘤总直径≥7 cm(P=0.002,RR=6.578)、微血管侵犯(P=0.001,RR=5.737)、低分化(P=0.048,RR=4.335)因素与肿瘤复发显著相关.结论 部分大肝癌经肝动脉栓塞化疗治疗降期后可以成功实施根治性肝切除和肝移植,并获得满意的远期预后.

Abstract：

Objective To evaluate the feasibility of sequential liver resection or liver transplantation following downstaging of larger hepatocellular carcinoma (HCC) by transcatheter arterial chemoembolization (TACE). Methods A retrospective study was conducted. And a total of 58 patients with unresectable larger HCC (diameter ＞5 cm) from June 2006 to March 2010 underwent TACE. According the outcomes of TACE, they received liver transplantation ( LT, n = 36) and liver resection ( LR, n = 22) respectively. The overall survival (OS) and recurrence-free survival (RFS) rates were calculated by the Kaplan-Meier method. The multivariate analyses for the influencing factors were evaluated by the Cox proportional hazard model. Results The median follow-up period of 58 cases was 22 months and the median survival time 23.57±1.54 months. The 1 -, 2 - , 3 - year OS and RFS rates after LT was 94%, 84% & 73% and 88% , 75%& 64% respectively. The median recurrence time was 12. 3 ± 6. 4 months ( range: 3 - 23). Twenty-eight patients had adequate downstaging to qualify for LT under the Milan criteria The 1 - , 2 - , 3 - year OS and RFS of the downstaging group was better than those of the non-downstaging group (OS: 96%, 88%, 75%vs92%,48%,48% P=0.067; RFS:95%,95%,79% vs76%,40%, 40% P=0.002). The1-,2 -, 3 -years OS and RFS after LR was 100%, 64% & 52% and 72%, 49% & 49% respectively. The median recurrence time was 9.3 ±4.5 months (range:3 -23). The long-term results of LT group following TACE were better than those of LR group( OS, P =0. 178; RFS, P =0. 139). The multivariate analyses showed that only pathologic total tumor diameter ＞7 cm (P =0. 002, RR =6. 578) , microvascular invasion ( P =0. 001, RR = 5. 737 ) and poor differentiation (P=0.048, RR = 4. 335 ) were significantly correlated with tumor recurrence. Conclusion Sequential liver resection and liver transplantation after downstaging by TACE are feasible for some larger HCCs. And the long-term prognosis is satisfactory.
