摘　　要：目的:比较PET-CT术前检测食管癌(EC)、非小细胞肺癌(NSCLC)淋巴结转移的准确度,观察其诊断EC、NSCLC淋巴结转移的临床价值。方法:43例EC患者及113例NSCLC患者术前1周接受PET-CT检查,以术后病理检查结果为金标准,计算并对比术前PET-CT诊断EC、NSCLC淋巴结转移的灵敏度、特异性及准确率,分析其临床参考价值。结果:43例EC患者共切取淋巴结350枚(188组),病理诊断检出59枚淋巴结转移(16.86%),113例NSCLC患者共切取淋巴结494枚(215组),病理诊断检出131枚淋巴结转移(26.52%)。术前PET-CT检测EC淋巴结转移的灵敏度、阴性预测值高于NSCLC,差异有统计学意义(P<0.05),术前PET-CT检测EC、NSCLC淋巴结转移的特异性、准确率、阳性预测值比较,差异无统计学意义(P>0.05)。结论:PET-CT术前检测EC、NSCLC淋巴结转移的参考价值均较高,且评估EC淋巴结转移的灵敏度更为理想。Objective：The objective of this study was to compare the accuracy of PET-CT on EC and NSCLC lymphatic metastasis and observe its clinical value in diagnose these lymphatic metastasis.Methods：43 cases of EC patients and 113 NSCLC patients were examined by means of PET-CT one week before operation.The pathological results were considered as the criteria to measure the accuracy.The sensitivity,specificity and accuracy of the preoperative and postoperative PET-CT were calculated and compared.Results：Of 43 EC patients,350（188 groups） lymphatic gland were excised and the pathological results showed that 59 lymphatic metastasis occurred（16.86%）;of 113 NSCLC patients,494（215 groups） lymphatic gland were excised and the pathological results showed that 131 lymphatic metastasis occurred（26.52%）.The test accuracy and negative predictive value of PET-CT on EC before operation were higher than that on NSCLC,and the difference was statistically significant（P〈0.05）.The specificity,positive predicative value and the accuracy of PET-CT on EC and NSCLC were compared and the difference was not statistically significant（P〉0.05）.Conclusions：PET-CT has higher reference value in the test accuracy of EC and NSCLS lymphatic metastasis and the sensitivity on the evaluation of EC lymphatic metastasis is relatively ideal.
