18F-FDG PET/CT与99Tcm-MDP骨显像诊断肿瘤骨转移价值的Meta分析

目的评价18F-FDG PET/CT与99Tcm-MDP骨显像对肿瘤骨转移早期诊断的价值。方法计算机检索MEDLINE、PubMend、EMbase、Ovid、Cochrane Library数据库,检索时间截至2010年,搜集18F-FDG PET/CT与99Tcm-MDP骨显像诊断恶性肿瘤骨转移的文献。由3位研究者根据纳入与排除标准独立筛选文献、提取资料和评价质量后,采用MetaDisc软件进行Meta分析,计算合并敏感性、特异性、诊断优势比(DOR),并绘制SROC曲线,计算曲线下面积(AUC)与Q*。结果最终纳入5个研究。Meta分析结果显示:18F-FDG PET/CT与99Tcm-MDP骨显像在诊断肿瘤骨转移的敏感性合并分别为0.95[95%CI(0.90,0.97)]和0.77[95%CI(0.71,0.83)],特异性合并分别为0.98[95%CI(0.97,0.99)]和0.90[95%CI(0.88,0.92)],DOR合并分别为602.81[95%CI(214.07,1 697.51)]和41.37[95%CI(8.15,210.05)];SROC AUC与Q*分别为0.984 2、0.901 7和0.945 4、0.833 1。结论应用18F-FDG PET/CT早期诊断肿瘤骨转移明显优于99Tcm-MDP骨显像。

Diagnosis Value of 18FDG-PET/CT and 99Tcm-MDP Bone Scan in Bone Metastases of Tumors: A Meta-analysis

Objective To use meta-analysis method to assess the efficacy of fluorine-18fluorode-oxyglucose positron emission tomography/computed tomography(PET/CT)(18F-FDG-PET/CT) scan and 99Tcm-methylene diphosphonate(99Tcm-MDP) bone scan(BS) on early diagnosis of bone metastases of cancer.Methods Computer-based retrieval was conducted on MEDLINE,PubMed,EMbase,Ovid,and The Cochrane Library(from their establishment to 2010) to search reports about diagnosing bone metastases of cancer with 18FDG-PET/CT and 99Tcm-MDP Bon...
