鼻腔非霍奇金淋巴瘤的CT诊断及临床预后

Non-Hodgkin s Lymphoma of Nasal Cavity:CT Diagnosis and Clinical Prognosis

摘要: 目的　探讨鼻腔NHL的CT影像学特征及预后。方法　回顾性分析我院 4 6例经病理证实为鼻腔NHL的CT影像, 纳入单因素Cox模型分析, 并对这些因素进行K M曲线和log rank test进行统计学推断。结果　 1、CT表现 :①位于鼻腔前部 4 0例, 占 86 .96 % (T/NK细胞型 34例, B细胞型 6例 )和鼻腔后部 6例, 占 13.0 4 %, 其中伴面部皮肤改变 2 0例 ;②浸润型 2 3例, 易侵犯邻近组织 2 0例 ;③骨质破坏呈虫蚀样或筛孔状改变 7例, 仅占 15 .2 2 %。 2、单因素分析示病灶形态、骨质改变和邻近器官受侵与生存率有关 (P <0 .0 5 )。 1、3、5年总生存率分别为 91.3%, 6 5 %和 5 2 .2 %。结论　CT征象不仅在原发鼻腔NHL中诊断有重要价值, 而且还能依据CT征象判断与预后的关系

Abstract: Objective To discuss the CT findings of non-Hodgkin s lymphoma (NHL) of nasal cavity and its prognosis. Methods The CT findings of 46 patients with nasal NHL comfirmed histopathology were respectively analysed. These data were brought into univariable Cox model system, then plotted K-M curves and finally performed statiscally analyses with log-rank-test. Results 1 CT findings showed as follow: ① 40 cases (T-cell 34, B-cell 6) located in anterior part of nasal cavity and 6 cases (T-cell 5,B-cell 1) in poste...
