摘要
目的评价ＭＲＩ在喉癌术前Ｔ分期中的价值。方法对５９例喉癌的ＭＲＩ资料进行回顾性分期，并与纤维喉镜及手术病理对照。结果ＭＲＩ对各期喉癌分期的准确性分别是：Ｔ１：９５％（２０／２１），Ｔ２：８８％（１５／１７），Ｔ３：８５％（１１／１３）Ｔ４：１００％（８／８）。纤维喉镜分期的准确性是：Ｔ１：９１％（１９／２１），Ｔ２：８８％（１５／１７），Ｔ３：４７％（８／１３），Ｔ４：１３％（１／８）。结论ＭＲＩ能准确判断会厌前间隙（ＰＥＳ）、喉旁间隙（ＰＧＳ）浸润及软骨破坏，因而可显著提高喉癌术前分期的准确性，对临床治疗方案选择具有重要意义。
Objective To evaluate the value of the preoperative T staging of laryngeal cancer by MRI. Methods The MRI data of 59cases of laryngeal cancer were retrospectively staged, and compared with the findings of laryngoscopy and postsurgical pathologic staging. Results The accuracy of staging in each T stage of laryngeal cancer was: T1:95%(20/21), T2:88%(15/17), T3:85%(11/13) T4:100%(8/8)byMRI ,vsT1:91%(19/21),T2:88%(15/17),T3:47%(8/13),T4:13%(1/8) by laryngoscopy. The total accuracy of MRI vs laryngoscopy was 92% (54/59) vs 73%(43/59). P<0.01. Conclusion MRI can correctly depict the invasion of the preepiglottic space (PES),paraglottic space (PGS) and cartilage by laryngeal cancer and can greatly improve the accuracy of preoperative staging . It was considered that MRI of great importance in determining appropriate therapy for laryngeal cancer.
