摘要 目的 研究评价^(99m)Tc-MIBI SPECT术前诊断肺癌及纵隔转移淋巴结的价值。方法 随机选取本院胸外科l997年3月~2000年12月间初诊“肺部阴影待查”患者100例,术前常规检查并加行^(99m)Tc-MIBI SPECT检查。男80例,女20例,平均年龄57.61±10.99岁。肺癌手术中规范清扫纵隔各组淋巴结,光学显微镜观察。计算核素断层显像之诊断敏感性,特异性,准确性,阳性预测值,阴性预测值,阳性拟然比、阴性拟然比等指标。对转移淋巴结假阴性显像,配对进行淋巴结图像分析,获取各切片转移癌细胞的面积值(μm^2)及其面积百分比。结果(1)^(99m)Tc-MIBI SPECT对支气管肺癌的诊断评价:敏感性(93.67%),特异性(61.90%),准确性(87.00%),阳性预测值(90.24%),阴性预测值(72.22%),阳性拟然比(2.47)及阴性拟然比(0.10)。(2)^(99m)Tc-MIBI SPECT对纵隔转移淋巴结的诊断评价:敏感性(85.19%),特异性(93.62%),准确性(90.54%),阳性预测值(85.19%),阴性预测值(93.62%),阳性拟然比(13.28)及阴性拟然比(l3.28)及阴性拟然比(0.16)。(3)淋巴结图像分析显示:淋巴结中转移癌细胞的数量同显像与否既有一定联系又非密切相关,淋巴结癌细胞数量(面积)并不是其显像与否的唯一因素。结论 本组显示了SPECT在肺癌诊断鉴别和纵隔转移淋巴结预测上的独特价值。 ve To evaluate the value of ^(99m)Tc-MIBISPECT in diagnosis of lung cancer and in pre-operative prediction ofmediastinal metastatic lymph nodes.To explore the pathologic baseof Technetium-99m-MIBI SPECT in diagnosing lung cancer andmediastinal metasatic lymph node.Methods 100 patients(80men,20 women;mean age 57061 yr)diagnosed'lung fieldshadow' were enrolled in this study. After the chest image of ^(99m)Tc-MIBI SPECTW,every patient underwent the operation, including the lung focus and mediastinal lymph nodes resection.The pathologicalresults were compared the pre-operative^(99m)Tc-MIBI SPECT image toobtain the statistic quota of diagnostic test.Results Thesensitivity, specificity and accuracy ofv(99m)Tc-MIBI SPECT were93.67%, 6l.90% and 87.00% respectively in lung cancer and85.l9%, 93.62% and 90.54%, respectively in mediastinalmetastatic lymph node. The pathologic study showed that the amountof metastasis in lymph node was related to the result of ^(99m)Tc-MIBISPECT in diagnosing mediastinal metastatic lymph node, but not theexclusive factor. Conclusion The ^(99m)Tc-MIBI SPECT is an usefuland noninvasive method for differentially diagnosing lung cancer andfor predicting mediastinal metastatic lymph node, and will give thesurgeons guidance to resect the mediastinal metasatic lympli nodes.
