摘要: 背景 磁共振波谱成像(MRS)可无创性分析活体组织多种代谢物的改变,对肿瘤性质的诊断、病理分级以及预后评估具有很大的临床价值,近年来已逐步应用于神经胶质瘤与脑转移瘤的鉴别诊断,但国内外文献报道的研究结论并不一致。目的 采用Meta分析的方法探讨MRS鉴别神经胶质瘤与脑转移瘤的临床价值。方法 计算机检索Cochrane Library、PubMed、EMBase、EMCC、OVID、中国知网、维普中文期刊数据库和万方数据知识服务平台等数据库关于MRS鉴别神经胶质瘤(神经胶质瘤组)与脑转移瘤(脑转移瘤组)的文献;检索时间为建库至2018年2月。两名研究者独立提取资料数据和评价纳入文献,依据纽卡斯尔-渥太华量表(NOS)评价纳入文献的质量。采用Stata 12.0软件进行Meta分析。结果 纳入14篇文献,460例患者。Meta分析结果显示,瘤周区,神经胶质瘤组N-乙酰天门冬氨酸(NAA)/肌酐(Cr)、NAA/胆碱(Cho)低于脑转移瘤组〔标准化均数差(SMD)=-0.59,95%CI(-0.96,-0.22),P=0.002;SMD=-1.90,95%CI(-3.30,-0.51),P=0.007〕,Cho/NAA、Cho/Cr高于脑转移瘤组〔SMD=1.51,95%CI(0.95,2.07),P<0.001;SMD=1.42,95%CI(0.84,2.00),P<0.001〕。瘤体区,神经胶质瘤组与脑转移瘤组NAA/Cr、NAA/Cho、Cho/Cr比较,差异均无统计学意义〔SMD=-0.28,95%CI(-0.67,0.10),P=0.153;SMD=-0.47,95%CI(-1.80,0.86),P=0.488;SMD=0.38,95%CI(-0.10,0.86),P=0.117〕;神经胶质瘤组Cho/NAA高于脑转移瘤组〔SMD=0.47,95%CI(0.16,0.78),P=0.003〕。结论 瘤周区,神经胶质瘤NAA/Cr、NAA/Cho低于脑转移瘤,Cho/NAA、Cho/Cr高于脑转移瘤;瘤体区,神经胶质瘤Cho/NAA高于脑转移瘤。通过MRS对比分析瘤周NAA/Cr、NAA/Cho、Cho/NAA和Cho/Cr,对神经胶质瘤与脑转移瘤的鉴别具有重要的临床价值。

Abstract: Background Magnetic resonance spectroscopy (MRS) imaging can non-invasively analyze the changes of various metabolites in living tissue,and has great clinical value for the diagnosis,pathological grading and prognosis evaluation of tumor properties.In recent years,it has been gradually applied to differential diagnosis of glioma and brain metastatic tumor,but the research conclusions reported in domestic and foreign literatures are inconsistent.Objective To evaluate the clinical value of MRS in differentiating gliomas from brain metastases using meta-analysis methods.Methods Digital knowledge service platforms,such as Cochrane Library,PubMed,EMBase,EMCC,OVID,CNKI,VIP and Wanfang Data Knowledge Service Platform were searched for relevant articles of MRS in differentiating glioma (glioma group) from brain metastases (brain metastases group) published in English and Chinese up to February 2018.Two researchers independently extracted data and assessed the relevant system evaluation literature according to diagnostic Newcastle-Ottawa Scale (NOS) tool.Meta analysis was performed by using Stata 12.0 software.Results Fourteen articles and 460 patients were included.The results of meta-analysis showed that in the around tumor,the NAA/Cr and NAA/Cho in the glioma group were lower than those in the brain metastases group 〔SMD=-0.59,95%CI(-0.96,-0.22),P=0.002;SMD=-1.90,95%CI(-3.30,-0.51),P=0.007〕,and Cho/NAA and Cho/Cr were higher than those of brain metastases group 〔SMD=1.51,95%CI(0.95,2.07),P<0.001;SMD=1.42,95%CI(0.84,2.00),P<0.001〕.In the tumor area,there were no statistically significant differences in NAA/Cr,NAA/Cho,Cho/Cr between glioma group and brain metastases group 〔SMD=-0.28,95%CI(-0.67,0.10),P=0.153;SMD=-0.47,95%CI(-1.80,0.86),P=0.488;SMD=0.38,95%CI(-0.10,0.86),P=0.117〕.Cho/NAA in glioma group was higher than that in brain metastases group 〔SMD=0.47,95%CI(0.16,0.78),P=0.003〕.Conclusion In the around tumor,the NAA/Cr,NAA/Cho in the glioma are lower than those in brain metastases,and Cho/NAA,Cho/Cr in the glioma are higher than those in brain metastases.In the tumor area,the Cho/NAA in the glioma is higher than that in brain metastases.It has important clinical value for the differentiation of glioma and brain metastases by contrasting analysis of the ratio of NAA/Cr,NAA/Cho,Cho/NAA and Cho/Cr in the peritumoral area through MRS.
