【摘要】：目的探讨鼻咽癌咽后淋巴结转移的最大短径诊断标准。方法回顾性分析817例初诊鼻咽癌患者的影像资料和临床资料。将有咽后淋巴结转移的患者按淋巴结的最大短径分组,分别以5mm和6mm为标准。分析以5mm和6mm为标准的2组间的总体生存率(OS),无远处转移生存率(DMFS)和无局部复发生存率(LRFS)的差异性。结果当以5mm为标准时,两组OS、DMFS、LRFS差异均无统计学意义(P均0.05);当以6mm为标准时,OS和DMFS的差异具有统计学意义(OS:P0.001;DMFS:P=0.001),LRFS的差异无统计学意义(P=0.380)。多因素分析显示咽后淋巴结转移的OS、DMFS、LRFS均不是鼻咽癌的独立预后因素。结论以≥6mm为诊断鼻咽癌咽后淋巴结转移的标准更为合理。
[Abstract]:Objective to investigate the diagnostic criteria of maximum short diameter metastasis of retropharyngeal lymph nodes in nasopharyngeal carcinoma. Methods the imaging data and clinical data of 817 nasopharyngeal carcinoma patients with retropharyngeal lymph node metastasis were retrospectively analyzed. Maximum short path grouping. The overall survival rate of the two groups with 5mm and 6mm were analyzed. No distant metastasis survival rate (DMFS) and local recurrence free survival rate (LRFSs) were different. The difference of LRFS was not statistically significant (P = 0.05). The difference between OS and DMFS was statistically significant when the standard was 6mm. There was no significant difference in DMF: P0. 001 LRFS. Multivariate analysis showed that there was no significant difference in DMFS in patients with retropharyngeal lymph node metastasis. LRFS is not an independent prognostic factor for nasopharyngeal carcinoma (NPC). Conclusion it is more reasonable to use 鈮，
