摘要:
目的 使用Meta分析的方法比较再次肝切除术与射频消融治疗亚洲复发性肝癌患者的安全性与疗效。 方法 系统检索PubMed、中国知网和万方数据库,日期自建库截止至2020年6月15日。由两位评价者独立检索并提取数据,采用RevMan 5.4.1软件进行Meta分析。 结果 共2项随机对照试验和18项回顾性队列研究符合纳入标准,均来自亚洲国家,包含2903例复发性肝癌患者。再次肝切除术组和射频消融组患者围手术期病死率分别为2%和0,围手术期并发症发生率分别为22.4%和3.3%。再次肝切除术组和射频消融组患者术后1、3、5年总生存率分别为92.3%、66.3%、51.1%和91.4%、69.2%、39.9%。两组患者术后1、3、5年无瘤生存率分别为67.9%、48.3%、34.4%和57.5%、27.9%、14.0%。Meta分析结果提示,两组患者的总生存率差异无统计学意义(HR=0.89,95%CI:0.77~1.02,P=0.10),但再次肝切除术组患者的无瘤生存率显著高于射频消融组(HR=0.79,95%CI:0.72~0.87,P<0.001)。 结论 目前证据显示,再次肝切除术治疗复发性肝癌有更高的无瘤生存率,但两组患者的总生存率相似。 -

Abstract:Objective To investigate the safety and efficacy of re-hepatic resection (rHR) versus radiofrequency ablation (RFA) in the treatment of recurrent hepatocellular carcinoma (RHCC) in Asia through a meta-analysis. Methods PubMed, CNKI, and Wanfang Data were searched for related studies published up to June 15, 2020. Two reviewers independently searched for the articles and extracted related data, and RevMan 5.4.1 was used to perform the meta-analysis. Results A total of 2 randomized controlled trials and 18 retrospective cohort studies met the inclusion criteria and involved 2903 patients with RHCC from Asian countries. The mortality rate in the perioperative period was 2% in the rHR group and 0 in the RFA group, and the incidence rate of perioperative complications was 22.4% in the rHR group and 3.3% in the RFA group. The 1-, 3-, and 5-year overall survival rates were 92.3%, 66.3%, and 51.1%, respectively, in the rHR group and 91.4%, 69.2%, and 39.9%, respectively, in the RFA group. The 1-, 3-, and 5-year disease-free survival rates were 67.9%, 48.3%, and 34.4%, respectively, in the rHR group and 57.5%, 27.9%, and 14.0%, respectively, in the RFA group. The Meta-analysis showed that there was no significant difference in overall survival rate between the two groups (hazard ratio [HR]=0.89, 95% confidence interval [CI]: 0.77-1.02, P=0.10), while the rHR group had a significantly higher disease-free survival rate than the RFA group (HR=0.79, 95% CI: 0.72-0.87, P < 0.001). Conclusion Current evidence shows that rHR may help to achieve a higher disease-free survival rate than RFA in the treatment of RHCC, while rHR and RFA have a similar overall survival rate. -
