【摘要】：目的探討經(jīng)頸超聲測量鼻咽癌原發(fā)腫瘤體積與頸淋巴結(jié)轉(zhuǎn)移率及大小的關(guān)系。資料與方法 91例鼻咽癌患者首次放療前行二維超聲檢查,測量腫瘤及淋巴結(jié)大小,比較不同體積腫瘤的頸淋巴結(jié)轉(zhuǎn)移率及腫瘤大小與淋巴結(jié)大小的關(guān)系。結(jié)果 91例鼻咽癌患者中,頸淋巴結(jié)轉(zhuǎn)移61例,原發(fā)腫瘤體積≤10 cm3、11~30 cm3、31~50 cm3和≥51 cm3者的頸淋巴結(jié)轉(zhuǎn)移率分別為44.4%、78.1%、82.4%、66.7%,各組間比較差異有統(tǒng)計學(xué)意義(χ2=9.82,P0.05);其中頸淋巴結(jié)最大徑≥2 cm者在不同體積組分別占16.7%、80.0%、78.6%和50.0%,頸淋巴結(jié)最大徑2 cm者分別占83.3%、20.0%、21.4%和50.0%,兩者在不同體積組間轉(zhuǎn)移率差異有統(tǒng)計學(xué)意義(χ2=16.20,P0.01)。結(jié)論鼻咽癌原發(fā)腫瘤體積與頸淋巴結(jié)轉(zhuǎn)移率及大小密切相關(guān),經(jīng)頸超聲測量鼻咽癌原發(fā)腫瘤體積簡便易行,可以為研究鼻咽癌轉(zhuǎn)移和預(yù)后規(guī)律提供重要線索。
[Abstract]:Objective to investigate the relationship between primary tumor volume and cervical lymph node metastasis by transcervical ultrasound. Materials and methods 91 patients with nasopharyngeal carcinoma were examined by two dimensional ultrasound before radiotherapy for the first time. The tumor and lymph node size were measured, and the relationship between cervical lymph node metastasis rate and tumor size and lymph node size were compared. Results among 91 patients with nasopharyngeal carcinoma, 61 had cervical lymph node metastasis. The cervical lymph node metastasis rates of patients with primary tumor volume 鈮，
