【摘要】：目的探讨经颈超声测量鼻咽癌原发肿瘤体积与颈淋巴结转移率及大小的关系。资料与方法 91例鼻咽癌患者首次放疗前行二维超声检查,测量肿瘤及淋巴结大小,比较不同体积肿瘤的颈淋巴结转移率及肿瘤大小与淋巴结大小的关系。结果 91例鼻咽癌患者中,颈淋巴结转移61例,原发肿瘤体积≤10 cm3、11~30 cm3、31~50 cm3和≥51 cm3者的颈淋巴结转移率分别为44.4%、78.1%、82.4%、66.7%,各组间比较差异有统计学意义(χ2=9.82,P0.05);其中颈淋巴结最大径≥2 cm者在不同体积组分别占16.7%、80.0%、78.6%和50.0%,颈淋巴结最大径2 cm者分别占83.3%、20.0%、21.4%和50.0%,两者在不同体积组间转移率差异有统计学意义(χ2=16.20,P0.01)。结论鼻咽癌原发肿瘤体积与颈淋巴结转移率及大小密切相关,经颈超声测量鼻咽癌原发肿瘤体积简便易行,可以为研究鼻咽癌转移和预后规律提供重要线索。
[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，
