该研究旨在明确鼻咽癌(NPC)转移淋巴结囊性变(CLNM)的发生率和其对预后的意义。对257例NPC患者进行回顾,分析CLNM在MRI或CT的表现。数据采用Kaplan-Meier法进行统计学分析。结果:111(43.2%)例患者出现CLNM。总体而言,CLNM患者疾病别生存率(DSS)更低(P<0.001),总生存率(OS)更低(P<0.001)。基于淋巴结状态分析,N2患者CLNM常常出现更高的远处转移率(P=0.007)、更低
This study aimed to clarify the incidence of lymph node cystic degeneration (NPC) of nasopharyngeal carcinoma (NPC) and its significance for prognosis. 257 NPC patients were reviewed, CLNM in the performance of MRI or CT. Data were analyzed by Kaplan-Meier method. Results: CLNM occurred in 111 (43.2%) patients. Overall, disease-free survival (DSS) was lower in patients with CLNM (P <0.001) and overall survival (OS) was lower (P <0.001). Based on the analysis of lymph node status, CLNM in patients with N2 often showed higher distant metastases (P = 0.007), lower
