基于美国肿瘤放射治疗协会颈部淋巴结分区标准的转移性淋巴结影像分析

Imaging analysis of cervical lymph node metastasis based on the Radiation Therapy Oncology Group Guidelines

目的 :探讨基于美国肿瘤放射治疗协会(RTOG)颈部淋巴结分区标准的转移性淋巴结分布与原发恶性肿瘤的相关性,为临床治疗及预后评估提供依据。方法:回顾性分析经手术病理证实的154例原发肿瘤颈部淋巴结转移患者的影像资料,分析颈部转移性淋巴结的分布特点及其与原发肿瘤的相关性。结果:颈部转移性淋巴结的分布特点与其原发肿瘤的来源有明显相关性。多数头颈部原发恶性肿瘤可发生颈部淋巴结转移,其中以Ⅱb区最常见,Ⅱa区、Ⅲ区也是常见的转移部位,Ⅰ区受累少见。结论:颈部转移性淋巴结分区与其原发恶性肿瘤的淋巴引流部位密切相关。RTOG颈部淋巴结分区对判断颈部转移性淋巴结原发恶性肿瘤来源有重要参考价值。

Objective:To investigate the correlation between metastatic lymph node distribution and primary malignant tumor based on the Radiation Therapy Oncology Group(RTOG) cervical lymph node zoning criteria,aiming to improve the diagnostic accuracy of the disease.Methods:Imaging data of 154 patients with cervical metastatic lymph nodes of the neoplasm proved by surgery and pathology were reviewed retrospectively.The relationship between the distribution of cervical lymph node metastasis and the location of the primary tumor was analyzed.Results:There was an obvious relationship between the distribution of cervical lymph node metastasis and the location of the primary tumor.The lymph nodes in Ⅱb area were the most commonly involved,followed by Ⅱ a,Ⅲ area,Ⅰ area less lymph node involvement.Conclusions:Distribution of cervical lymph node metastasis is related to lymphatic drainage pathways of the primary tumor.Distribution of cervical lymph node metastasis based on Radiation Therapy Oncology Group Guidelines plays a valuable role in evaluating the origin of the primary tumor.
