MRI在喉癌术前分期中的临床应用价值

目的:探讨MRI在喉癌术前诊断、分期中的临床应用价值。方法:对114例行电子喉镜检查并经病理学证实为喉癌的患者行术前MRI扫描,根据图像资料判断肿瘤侵及范围及判断有无淋巴结转移;同时进行术前分期、分型,并与术后病理分期、分型对照研究。结果:术前MRI T1期27例,其中25例经病理证实为T1期,2例为T2期,准确率为92.6%;术前MRI T2期39例,其中经病理证实35例为T2期,3例T1期,1例T3期,准确率为89.7%;术前MRI T3期29例,其中经病理证实25例为T3期,4例T2期,准确率为86.2%;术前MRI T4期17例,其中经病理证实15例为T4期,2例T3期,准确率为88.2%;MRI术前T分期总准确率为87.7%。N1期准确率为81.8%,N2期准确率为94.1%。结论:MRI图像能很好地显示喉癌肿块的侵及范围及淋巴结转移等,对喉癌的术前分期、分型及制定合理的手术方案具有指导意义。

The Clinical Application Value of MRI in the Preoperative Staging of Laryngeal Carcinoma

Objective:To investigate the clinical value of pretreatment surgical magnetic resonance images (MRI) in the preoperative staging of laryngeal carcinoma.Methods:1 14 patients with laryngeal carcinoma diagnosed by electrical laryngoscope were studied by pretreatment surgical MRI examinatio. According to the images the tumor and lymphadenopathy were investigated, and the classification and staging of tumor were compared with pathological results.Results:27 cases of T1 were confirmed by MRI, in which 25 cases were confirmed by pathology; 2 cases were T2, and the accuracy of T1 staging was 92.6%; 39 cases of T2 were confirmed by MRI, in which 35 cases were confirmed by pathology, 3 cases were T1, 1 case was T3, and the accuracy of T2 staging was 89.7%; 29 cases of T3 were confirmed by MRI, in which 25 cases were confirmed by pathology, 4 cases were T2, and the accuracy of T3 staging was 86.2%; 1 7 cases of T4 were confirmed by MRI, in which 1 5 cases were confirmed by pathology, 2 cases were T3, and the accuracy of T4 staging was 88.2%, and the accuracy of T staging was 87.7%. In preoperative N staging, N1 was 81.8%, while N2 was 94.1%.Conclusion:MRI can display tumor infiltration and lymph node metastasi, which could be considered as a helpful diagnostic method that can contribute to the preoperative staging of laryngeal tumor and further clinical decision made in these patients.
