时间间隔对肝动脉化疗栓塞术序贯微波消融治疗肝细胞癌的影响

  目的  分析时间间隔对经肝动脉化疗栓塞术（transarterial chemoembolization，TACE）后序贯微波消融（MWA）治疗肝细胞癌（hepatocellular carcinoma，HCC）的影响。  方法  回顾性分析2016年2月至2018年12月在昆明市第三人民医院接受TACE和MWA后复发的71例HCC患者，32例在TACE术后4周内序贯MWA治疗（序贯治疗组），39例在TACE术4周后接受延迟MWA治疗（延迟治疗组）。观察2组的生存期和无进展生存期，采用Kaplan-Meier法绘制生存曲线，使用多元Cox比例风险回归评估分析预后因素，对比2组的不良反应。  结果  序贯治疗组和延迟治疗组的中位生存期分别为35.3个月、29.1个月，序贯治疗组的无进展生存期为27个月，延迟治疗组的无进展生存期为13.8个月。序贯治疗组有更好的生存期（HR，0.601；95%CI 0.378～0.796；P = 0.037）和更长的无进展生存期（HR，0.779；95%CI 0.415～0.821；P = 0.004）。最大肿瘤直径、肿瘤个数和时间间隔是影响生存期和无进展生存期的因素，Child-Pugh分级是影响生存期的因素，但不会影响无进展生存期。  结论   在4周内实施TACE序贯MWA比超过4周实施延迟MWA治疗肝细胞癌，有更好的中位生存期和无进展生存期，且不增加不良反应。

Effect of Time Interval on the Outcome with Transarterial Chemoembolization Followed Microwave Ablation with Hepatocellular Carcinoma

  Objective   To analyse the effect of time interval on the outcome of microwave ablation （MWA）treatment of hepatocellular carcinoma （HCC） after transarterial chemoembolization （TACE）.   Methods  A retrospective analysis of recurrent 71 HCC patients after receiving TACE and MWA at the 3rd People’s Hospital of Kunming from February 2016 to December 2018; with 32 patients received sequential MWA treatment within 4 weeks after TACE （sequential Treatment group）, and 39 patients received delayed MWA treatment （delayed Treatment group） 4 weeks after the completion of TACE, the overall survival （OS） and progression-free survival （PFS） of two groups were observed. Survival curve was plotted using Kaplan-Meier, the multiple Cox proportional hazard regression was used to analyze prognostic factors, compare adverse reactions between the two groups.   Results  The median OS of the sequential group and the delayed group were 35.3 months and 29.1 months, respectively. PFS in the sequential group was 27 months, and 13.8 months in the delayed group. The sequential group had better overall survival OS （HR, 0.601; 95%CI, 0.378-0.796; P = 0.037） and longer PFS （HR, 0.779; 95%CI, 0.415-0.821; P = 0.004）. Maximum tumor diameter, number of tumors, and time interval are factors that affect OS and PFS. Child-Pugh classification is a factor that affects OS but does not affect PFS.   Conclusion  TACE plus sequential MWA within 4 weeks was more effective for treatment HCC than delayed MWA, and does not increase adverse reactions.
