【摘要】：目的探討鼻咽癌咽后淋巴結(jié)轉(zhuǎn)移的最大短徑診斷標(biāo)準(zhǔn)。方法回顧性分析817例初診鼻咽癌患者的影像資料和臨床資料。將有咽后淋巴結(jié)轉(zhuǎn)移的患者按淋巴結(jié)的最大短徑分組,分別以5mm和6mm為標(biāo)準(zhǔn)。分析以5mm和6mm為標(biāo)準(zhǔn)的2組間的總體生存率(OS),無遠(yuǎn)處轉(zhuǎn)移生存率(DMFS)和無局部復(fù)發(fā)生存率(LRFS)的差異性。結(jié)果當(dāng)以5mm為標(biāo)準(zhǔn)時(shí),兩組OS、DMFS、LRFS差異均無統(tǒng)計(jì)學(xué)意義(P均0.05);當(dāng)以6mm為標(biāo)準(zhǔn)時(shí),OS和DMFS的差異具有統(tǒng)計(jì)學(xué)意義(OS:P0.001;DMFS:P=0.001),LRFS的差異無統(tǒng)計(jì)學(xué)意義(P=0.380)。多因素分析顯示咽后淋巴結(jié)轉(zhuǎn)移的OS、DMFS、LRFS均不是鼻咽癌的獨(dú)立預(yù)后因素。結(jié)論以≥6mm為診斷鼻咽癌咽后淋巴結(jié)轉(zhuǎn)移的標(biāo)準(zhǔn)更為合理。
[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，
