摘要: | 目的:系统评价口服支链氨基酸对肝细胞癌患者行肝切除术或射频消融(RFA)术后肝细胞癌复发率和白蛋白水平的影响,为其临床应用提供循证参考。方法:计算机检索自建库起至2017年10月PubMed、Embase、CENTRAL、中国期刊全文数据库、维普网中收录的口服支链氨基酸(试验组)对比常规饮食(对照组)对肝细胞癌肝切除术或RFA术后患者肝细胞癌复发率和白蛋白水平影响的随机对照试验(RCT)和临床对照研究,进行资料提取并采用Cochrane系统评价员手册5.2.0和纽卡斯尔-渥太华量进行质量评价后,采用Rev Man 5.2 统计软件对术后1、2、3、4年肝细胞癌复发率及术后6、12个月的白蛋白水平进行Meta分析。结果:共纳入8项研究(6项RCT、2项队列研究),合计515例患者。Meta分析结果显示,两组患者术后1年{肝切除术[RR=0.79,95%CI(0.32,1.96),P=0.61]、RFA术[RR=0.82,95%CI(0.30,2.23),P=0.70]}、2年{肝切除术[RR=0.89,95%CI(0.56,1.41),P=0.62]、RFA术[RR=0.76,95%CI(0.45,1.29),P=0.31]}、3年{肝切除术[RR=0.73,95%CI(0.36,1.48),P=0.38]、RFA术[RR=0.81,95%CI(0.57,1.13),P=0.22]}肝细胞癌复发率比较,差异均无统计学意义;试验组患者术后4年肝细胞癌复发率显著低于对照组[RR=0.72,95%CI(0.58,0.90),P=0.004],但采用肝切除术差异无统计学意义[RR=0.8,95%CI(0.56,1.15),P=0.23],采用RFA术试验组患者肝细胞癌复发率显著低于对照组[RR=0.68,95%CI(0.51,0.90),P=0.007]。两组患者术后6个月[SMD=0.34,95%CI(-0.40,0.89),P=0.46]、12个月{[SMD=0.34,95%CI(-0.04,0.73),P=0.08]时白蛋白水平比较,差异均无统计学意义,其中肝切除术[SMD=0.22,95%CI(-0.31,0.75),P=0.41]、RFA术[SMD=0.53,95%CI(0.01,1.06),P=0.05]}白蛋白水平比较,差异均无统计学意义。结论:手术方式不同,口服支链氨基酸对肝细胞癌复发率的影响不同;口服支链氨基酸可降低RFA术后患者肝细胞癌远期复发率,但对肝切除术患者无明显影响;其对白蛋白的影响尚不明确,需扩大样本量进一步研究。 |
ABSTRACT: | OBJECTIVE: To evaluate the effects of oral branched-chain amino acids on the recurrence rate of hepatocellular carcinoma and albumin level in patients with hepatocellular carcinoma after hepatectomy or radiofrequency ablation (RFA), and to provide evidence-based reference for clinical treatment. METHODS: Retrieved from PubMed, Embase and CENTRAL, CJFD, VIP during database establishment to Oct. 2017, randomized controlled trial (RCT) and randomized controlled study about the effects of oral branched-chain amino acids (trial group) versus routine diet (control group) on the recurrence of hepatocellular carcinoma and albumin level in patients with hepatocellular carcinoma after hepatectomy or RFA were collected. After data extraction and quality evaluation with Cochrane system evaluator manual 5.2.0 and the Newcastle-Ottawa scale (NOS), Meta-analysis was performed for the recurrence rate of hepatocellular carcinoma 1, 2, 3, 4 years after surgery and albumin level 6 and 12 months after surgery by using Rev Man 5.2. RESULTS: A total of 8 studies (6 RCTs, 2 cohort studies) were included, involving 515 patients. Results of Meta-analysis showed that there was no statistical significance in 1-year {hepatectomy [RR=0.79, 95%CI(0.32, 1.96), P=0.61], RFA [RR=0.82, 95%CI(0.30,2.23), P=0.70]}, 2-year {hepatectomy [RR=0.89,95%CI(0.56, 1.41),P=0.62], RFA[RR=0.76, 95%CI(0.45,1.29), P=0.31]} or 3-year {hepatectomy [RR=0.73, 95%CI(0.36, 1.48), P=0.38], RFA [RR=0.81, 95%CI(0.57,1.13), P=0.22]} recurrence rate of hepatocellular carcinoma between 2 groups after surgery. The recurrence rate of hepatocellular carcinoma in trial group was significantly lower than control group [RR=0.72, 95%CI(0.58, 0.90), P=0.004] 4 years after surgery, but there was no statistical significance in the difference of hepatectomy [RR=0.8, 95%CI(0.56,1.15), P=0.23]. The recurrence rate of hepatocellular carcinoma in trial group was significantly lower than control group [RR=0.68, 95%CI(0.51,0.90), P=0.007] after receiving RAF. There was no statistical significance in albumin level between 2 groups 6 months after [SMD=0.34,95%CI(-0.40,0.89), P=0.46] and 12 months after surgery {[SMD=0.34,95%CI(-0.04,0.73), P=0.08], hepatectomy [SMD=0.22,95%CI(-0.31,0.75), P=0.41], RFA [SMD=0.53,95%CI(0.01,1.06), P=0.05]}. CONCLUSIONS: The effects of oral administration of branched-chain amino acids on the recurrence rate of hepatocellular carcinoma are different due to different surgery modes. The oral administration of branched-chain amino acids can reduce the long-term recurrence rate of hepatocellular carcinoma in RFA patients, but had no effect on hepatectomy. The effect of branched-chain amino acids on white protein is not yet clear. It is necessary to expand the sample size for further study. |
