【摘要】：目的：本研究旨在探討鼻咽癌區(qū)域淋巴結(jié)轉(zhuǎn)移的影像特點,為臨床分期、治療及預后判定提供依據(jù)。 資料與方法：收集2009年1月至2011年6月間1298例經(jīng)病理證實的在廣西醫(yī)科大學第一附屬醫(yī)院放射科行MRI檢查的首診鼻咽癌患者影像資料,并根據(jù)RTOG2006版影像學頸部淋巴結(jié)分區(qū)標準確定淋巴結(jié)位置,分析淋巴結(jié)在各區(qū)分布特點及跳躍性轉(zhuǎn)移情況,同時分析不同T分期各區(qū)淋巴結(jié)轉(zhuǎn)移率及淋巴結(jié)不同直徑之間包膜外侵的差別。 結(jié)果：本組患者中有1067例(82.2%)出現(xiàn)轉(zhuǎn)移淋巴結(jié),各區(qū)分布如下：Ⅰb區(qū)20例(1.5%),Ⅱa區(qū)604例(46.5%),Ⅱb區(qū)883例(68.0%),Ⅲ區(qū)330例(25.4%),Ⅳ區(qū)78例(6.0%),Ⅴa區(qū)162例(12.5%),Ⅴb區(qū)49例(3.8%),咽后967例(74.5%),跳躍性轉(zhuǎn)移9例(0.69%)。各區(qū)共檢出轉(zhuǎn)移淋巴結(jié)2464個,其中包膜外侵1589個(64.52%),包膜外侵比例隨淋巴結(jié)直徑增大而增大(P=0.000)。淋巴結(jié)轉(zhuǎn)移與T分期之間無明確相關(guān)性。 結(jié)論：鼻咽癌區(qū)域淋巴結(jié)轉(zhuǎn)移以Ⅱ區(qū)和咽后淋巴結(jié)最多見；Ⅰ區(qū)轉(zhuǎn)移率極低；跳躍性轉(zhuǎn)移極為少見。淋巴結(jié)包膜外侵比例與最大徑正相關(guān)。T分期和各區(qū)淋巴結(jié)轉(zhuǎn)移之間無相關(guān)性。
[Abstract]:Objective: to investigate the imaging features of regional lymph node metastasis in nasopharyngeal carcinoma (NPC) and to provide evidence for clinical staging, treatment and prognosis. Materials and methods: from January 2009 to June 2011, 1298 patients with nasopharyngeal carcinoma (NPC) who had been examined by MRI in Department of Radiology, first affiliated Hospital of Guangxi Medical University, were collected from January 2009 to June 2011. The location of cervical lymph nodes was determined according to RTOG2006 imaging criteria, and the distribution characteristics of lymph nodes in each region and the status of jumping metastasis were analyzed. At the same time, the difference of lymph node metastasis rate and different diameter of lymph nodes in different T stage was analyzed. Results: there were 1067 cases (82.2%) with metastatic lymph nodes in this group. The distribution was as follows: 20 cases (1.5%) in area 鈪，
