目的评价PET显像与CT/MRI和临床触诊比较在舌癌颈部淋巴结转移判定中的应用价值.方法 38例舌癌患者在术前两周分别进行FDG PET与CT/MRI检查,分别获取PET、CT/MRI和临床触诊的淋巴结状况并以病理结果为金标准分析三种方法在敏感性、特异性及准确率方面的差异.结果 PET在判定淋巴结转移的敏感性上比CT/MRJ和临床触诊分别高11.1%(83.3%vs 72.2%,P=0.423)和16.6%(83.3%vs 66.7%,P=0.248);特异性比CT/MRI和临床触诊分别高5%(80%vs 75%,P=0.703)和15%(80%vs 65%,P=0.288).PET、CT/MRI和临床触诊的准确率分别是81.6%,73.7%和65.8%.结论 PET在舌癌颈部淋巴结转移判定中的敏感性、特异性及准确率方面略好于CT/MRI和临床触诊.虽然结果无统计学上的差异,我们仍认为PET作为舌癌淋巴结转移判定中的一种辅助方法有重要的作用.

Objective To assess the value of PET in the identification of cervical nodal metastases of tongue cancer in comparison with CT/MRI and clinical palpation. Methods Thirty-eight patients with tongue cancer underwent PET and CT/MRI within 2 weeks before surgery. The results of PET, CT/MRI, and clinical palpation were interpreted separately to assess the regional lymph node status, using histopathological analysis as the golden standard. The differences in the sensitivity, specificity and accuracy among the imaging modalities and clinical palpation were analyzed. Results The sensitivity of PET for nodal metastasis identification was 11.1% higher than that of CT/MRI (83.3% vs 72.2%, P=0.423) and 16.6% higher than that of clinical palpation (83.3% vs 66.7%, P=0.248). The specificity of PET was 5% higher than that of CT/MRI (80% vs 75%, P=0.703) and 15% higher than that of clinical palpation (80% vs 65%, P=0.288). The accuracy of PET, CT/MRI, and clinical palpation in identifying cervical nodal metastases was 81.6%, 73.7% and 65.8%, respectively. Conclusion The sensitivity, specificity and accuracy of PET for detecting cervical nodal metastases are greater than those of CT/MRI and clinical palpation. Although the results failed to show statistically significant differences, we still recommend that PET be used as a supplementary modality for identifying nodal metastases of tongue cancer.
