摘要
目的系统评价18氟-脱氧葡萄糖正电子发射计算机断层成像术(18F-FDGPET-CT)对胃癌术前分期的诊断价值。方法通过检索PubMed、EMbase、Coehrane、CBM和CNKI数据库相关文献.根据QUADAS评价量表对文献质量进行评价,并采用MetaDisc软件对其诊断的敏感性,特异性等进行合并分析和异质性检验。结果15篇文献符合纳入标准,合并分析结果显示,18F-FDGPET—CT对胃癌原发灶诊断的敏感度为0.921(95%CI:0.871—0.956),特异度为0.895(95%CI:0.785—0.960),阳性似然比为5.12(95%CI:2.69~9.73),阴性似然比为0.13(95%CI:0.08—0.20),SROC曲线下面积(AUC)为0.9520;对局部淋巴结转移诊断的敏感度为0.613(95%CI:O.555-0.668),特异度为0.986(95%CI:0.960~0.997),阳性似然比为11.68(95%CI:5.52—24.73),阴性似然比为0.36(95%CI:0.24~0.55),AUC为0.9343;对远处转移灶诊断的敏感度为0.792(95%CI:0.703~0.865),特异度为0.976(95%CI:0.951~0.990),阳性似然比为16.70(95%CI:9.00~39.97),阴性似然比为0.26(95%CI:0.18—0.39),AUC为0.9454。结论。18F-FDGPET-CT应用于胃癌术前分期具有较高的诊断价值。
Objective To comprehensively in preoperative staging. Methods Relevant studies evaluate the diagnostic value of lSF-FDG PET/CT published until March 31st, 2012 were identified in the PubMed, EMBASE, Cochrane, CBM, CNKI databases. The studies were accessed according to QUADAS and the value of sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), AUC were pooled by MetaDisc software. Results Fifteen studies were included. ISF-FI)G PET/CT was able to identify primary tumor with overall sensitivity, specificity, PLR, NLR, and AUC of 0.921(0.871-0.956), 0.895(0.785-0.960), 5.12(2.69-9.73), 0.13(0.08-0.20), 0.9520, respectively. While the diagnostic performance of tSF-FDG PET/CT for regional lymph node status was less reliable, with overall sensitivity, specificity, PLR, NLR, and AUC of 0.613 (0.555-0.668), 0.986(0.960- 0.997 ), 11,68 ( 5.52-24.73 ), 0.36 (0.24-0.55), 0.9343 respectively. As for distant metastases, the diagnostic performance was with overall sensitivity, specificity, PLR, NLR, and AUC of 0.792(0.703- 0.865), 0.976(0.951-0.990), 16.70(9.00-39.97), 0.26(0.18-0.39), 0.9454 respectively. Conclusions ~8F-FDG PET/CT is valuable for preoperative staging of gastric cancer.
