虽然计算机断层扫描和磁共振成像有助于识别头颈部癌症的转移疾病，但在评估淋巴结病方面仍然存在不足。这项研究是为了评估用于检测颈淋巴转移的放射学标准的准确性。对36例鳞状细胞癌患者颈淋巴清扫的957个淋巴结的形态特征进行了显微镜观察。发现大量直径小于10 mm的恶性结节，结外扩散也发生在相当大比例的小结节中。由于目前评估颈部淋巴结状况的放射学标准主要基于大小，研究结果表明，在检测转移性疾病的能力方面存在重大限制。新的方法，以改善头颈癌的分期进行了讨论。
Although computed tomography and magnetic resonance imaging have contributed to the ability to identify metastatic disease in head and neck cancer, inadequacies in evaluating lymphadenopathy still exist. This study was undertaken to estimate the accuracy of radiological criteria used to detect cervical lymph node metastases. The morphological characteristics of 957 lymph nodes from 36 neck dissections from patients with squamous cell cancer were examined microscopically. A large number of malignant nodes were found to have diameters of less than 10 mm, Extranodal spread also occurred in a substantial percentage of smaller nodes. Because the present radiological criteria for assessing cervical lymph node status are based largely on size, findings indicate major limitations in the capabilities of detecting metastatic disease. New modalities to improve the staging of head and neck cancer are discussed.
