Fifty-six patients with laryngeal cancer were examined. The rate of correct diagnosis of clinical staging was 64.3%. Whereas the rate of correct diagnosis of staging by CT was markedly improved, 89.3%. In particular, CT facilitated correct diagnosis of T4. Supraglottic T3 cancer is diagnosed on the basis of deep infiltration or fixation of the hemi-larynx. Disappearance of the pre-epiglottic space or ulcer formation was recognized as a CT finding of deep infiltration. Disappearance of the paraglottic space and dislocation of the arytenoid cartilage were used as the standard for CT findings of laryngeal T3 cancer. CT allowed diagnosis to be made in 84.4% of cases which were pathologically determined to be T4. It can be said that CT is a very effective method for staging diagnosis in patients with laryngeal cancer. Fifty-seven patients with hypopharyngeal cancer and cancer of the cervical esophagus were also examined. When 40 post-surgical patients were compared according to pathological classification of T, the rate of correct diagnosis of clinical staging was 77.5% while that of staging diagnosis by CT was 82.5%. The rate of correct diagnosis by postoperative CT was 80.0% compared with the pathological determination of depth of invasion. The diagnosis of depth of invasion by CT on initial examination is thus an effective means for the determination of prognosis.
对56例喉癌患者进行了检查。临床分期的正确诊断率为64.3%。而CT分期的正确诊断率显著提高，为89.3%。特别是，CT有助于T4的正确诊断。声门上T3癌是根据半喉的深度浸润或固定来诊断的。会厌前间隙消失或溃疡形成被认为是深度浸润的CT表现。声门旁间隙消失和杓状软骨脱位被用作喉T3癌CT表现的标准。CT对病理诊断为T4的病例的诊断率为84.4%。可以说，CT是喉癌患者分期诊断的一种非常有效的方法。还对57例下咽癌和颈段食管癌患者进行了检查。当根据T的病理分类对40例术后患者进行比较时，临床分期的正确诊断率为77.5%，而CT分期诊断率为82.5%。与病理确定的浸润深度相比，术后CT的正确诊断率为80.0%。因此，初次检查时CT对浸润深度的诊断是判断预后的有效手段。
