老年人喉癌侵犯范围的CT和MRI评价

Assessing invasive extent laryngeal carcinoma of the aged patients with CT and MRI

目的 探讨 CT、MRI对喉癌侵犯范围及术前分期的价值。方法 回顾性分析 2 6例喉癌病人的 CT、MRI表现 ,根据 CT、MRI征象判断肿瘤的侵犯范围及术前分期 ,并将此结果与手术病理结果相对照。结果 CT、MRI判断肿瘤侵犯邻近部位或结构的敏感性分别为 94.5% (1 2 1 /1 2 8)、94.0 % (79/ 84) ,阳性预测正确率分别为 85.3% (1 2 1 / 1 4 2 )、86.9% (79.91 ) ,假阴性率分别为 5.4% (7/ 1 2 8)、5.9% (5/ 84)。术前 CT、MRI对原发肿瘤分期的准确性分别为 80 .0 % (1 2 / 1 5)、85.7% (6/ 7)。结论 CT、MRI能较准确地反映喉癌的侵犯范围及术前分期 ,这对于喉癌的临床治疗有很大帮助。

Objective To explore the value of CT and MRI on invasive range and preoperative staging of the laryngeal carcinoma in the aged patients.Methods CT and MRI information of 26 cases with laryngeal catcinoma was analyzed retrospectively. The tumor invasive extent and staging with CT and MRI were compared with operation-pathologic results.ResultsThe sensitivity, positive predictive value and the accuracy of tumor staging of CT and MRI in assessing invasion of latyngeal catcinoma were higher 〔94.5% (121/128) vs 94.0% (79/84) and 85.3% (121/142) vs 86.9% (79/91) and 80.0% (12/15) vs 85.7% (6/7), respectively〕.But 5.4% (7/128) and 5.9% (5/84) invasion were missed with CT and MRI.Conclusions CT and MRI are useful in assessing invasive range and preoperative staging of latyngeal catcinoma, and it is helpful to clinical treatment of this disease.
