肝脾联合切除治疗肝癌合并肝硬化脾功能亢进的Meta分析

目的 系统评价肝脾联合切除治疗肝癌伴肝硬化脾功能亢进的安全性和疗效.方法 计算机检索Medline、Embase、Cochrane图书馆、中国生物医学文献数据库、万方数据库中的相关文献,所有检索均截止至2009年8月.由2名评价员筛选和提取资料,并用Minors量表进行质量评估.对符合纳入标准的研究采用RevMan5软件进行统计分析.结果 共纳入5个非随机对照试验,患者总数476例(肝脾联合切除组232例,单纯肝癌切除组244例).结果 显示肝脾联合切除组(HS组)与单纯肝癌切除组(H组)手术病死率和术后并发症发生率比较无统计学差异,OR值(95%CI)分别为0.57(95%CI 0.12～2.66,P=0.47)和0.93(95%CI 0.59～1.46,P=0.75).与H组相比,HS组术后CD4+T细胞比例、CD4+T细胞/CD8+T细胞比值、白细胞和血小板计数均明显上升,其WMD值(95%CI)分别为7.90(7.01～8.79,P＜0.01)、0.75(0.70～0.80,P＜0.01)、5.47(5.13～5.82,P＜0.01)、174.89(116.61～233.18,P＜0.01).术后CD8+T细胞下降,其WMD值(95%CI为-7.66(-8.53～-6.79,P＜0.01).两组术后5年生存率的OR值(95%CI)为1.37(0.86～2.18,P=0.18).结论 根据已有文献,肝脾联合切除术治疗肝癌伴肝硬化脾功能亢进未增加手术病死率及术后并发症发生率,且可显著提高患者术后白细胞和血小板计数,改善机体免疫功能,但目前证据未表明能提高术后5年生存率.

Abstract：

Objective To systematically evaluate the efficacy and safety of combined hepatectomy and splenectomy in hepatocellular carcinoma complicated with hepatic cirrhosis and hypersplenism.Methods Medline (1966-August 2009), Embase (1974-August 2009), Cochrane Library, CBMdisc (1978-August 2009), and Wanfang Database were searched without language limitation. All relevant studies were screened and the data were extracted by two independent reviewers, and the methodological qualities of the included studies were evaluated by the Minors scale. The data were analyzed with the RevMan5 software. Results Five non-randomized comparative studies (NRCs) involving 476 patients (232 in HS group, 244 in control group) were enrolled into the analysis. There was no significant difference in the operative mortalities (OR=0. 57, 95%CI 0. 12-2. 66, P=0. 47) and postoperative morbidities (OR= 0. 93, 95 % CI 0.59- 1.46, P = 0.75) between the two groups. Compared with hepatectomy only, CD4+ T cell (WMD=7.90, 95%CI 7.01-8.79, P＜0.01), CD4+ T cell/CD8+ T cell ratio (WMD=0. 75, 95%CI 0. 70-0.80, P＜0.01), white blood cell count (WMD=5.47, 95%CI 5.13-5.82, P＜0.01) and platelet count (WMD=174.89, 95%CI 116.61-233.18,P＜0.01) were significantly higher, but CD8+ T cell (WMD = - 7.66, 95%CI - 8. 53～ - 6. 79,P＜0. 01) was lower compared with combined hepatectomy and splenectomy. There was no significant difference in the 5-year survival rates (OR= 1.37, 95%CI 0.86-2.18, P=0. 18). Conclusion Combined hepatectomy and splenectomy did not increase the operative mortalities and postoperative morbidities in hepatocellular carcinoma complicated with hepatic cirrhosis and hypersplenism. The white blood cell and platelet counts markedly increased after surgery. There was no evidence to show any improvement in the 5-year survival.
