基于磁共振鼻咽癌咽旁间隙侵犯与预后关系的探讨

[目的]探讨基于磁共振鼻咽癌咽旁间隙受侵对预后的影响。[方法]185例M0期鼻咽癌患者,按咽旁间隙的侵犯程度进行划分,无咽旁侵犯记为0级,有咽旁侵犯而无颈动脉鞘区侵犯记为1级,有颈动脉鞘区侵犯记为2级。Kaplan-Meier法计算生存率,Cox模型进行预后多因素分析。[结果]咽旁间隙受侵与颅底骨质破坏有明显相关性（r=0.15,P=0.041）。多因素分析显示咽旁受侵不是独立的预后因素,但颈动脉鞘区受侵是影响鼻咽癌总生存、无远处转移的独立预后因素。[结论]单纯的咽旁受侵不影响预后,颈动脉鞘区受侵是独立预后因素。

Prognostic Influence of Parapharyngeal Space Involvement in Nasopharyngeal Carcinoma Based on MRI

[Purpose] To investigate the prognostic influence of parapharyngeal space involvement in nasopharyngeal carcinoma based on magnetic resonance imaging (MRI). [Methods] One hundred and eighty-five cases with nasopharyngeal carcinoma M0 stage, tumor extension to parapharyngeal space was staged according to the degree of the parapharyngeal space extension: patients without parapharyngeal involvement recorded as grade 0, with parapharyngeal involvement but without area of carotid sheath invasion recorded as grad...
