CT对头颈部恶性肿瘤颈淋巴结转移的诊断价值──临床／CT／病理对照研究

Computed Tomography of Cervical Lymph Node Metastasis in the Malignant Tumor of the Head and Neck──A Clinical,Computed Tomographic and Pathologic Correlative Study

对３９例头颈部恶性肿瘤患者的５０例拟行预防性颈淋巴清扫术的颈部，术前应用ＣＴ扫描其颈部前瞻性评估其颈淋巴结内是否有肿瘤转移，并与颈部触诊检查及术后颈清标本的病理检查结果对照。结果表明：ＣＴ对头颈部恶性肿瘤颈淋巴结转移诊断的准确率（９０．００％，４５／５０）显著地高于（Ｐ＜０．００５）触诊检查的结果（６６．００％，３３／５０）。这表明：在诊断头颈部恶性肿瘤颈淋巴结转移方面，颈部ＣＴ扫描比颈部触诊检查更准确、可靠，并能提供更多有关淋巴结的融合、被膜外转移的资料，从而有助于临床医生术前为病人制定出更加准确、合理的治疗方案。

Fifty lesions(from 39 patients with malignant tumor in the head and neck)underwent radical or prophylactic neck dissection and preoperative CT scanning,The cervical palpation,CT diagnosis and pathological finding were correlated.CT accuracy was then compared with clinical accuracy.This research showed the overall accuracy of CT diagnoses to be 90.00% vs 66.00% by clinical palpation,Comparison with clinical accuracy showed the CT scan was more accurate and reliable.CT can provide much more information about cervical lymph node metastasis of malignant tumor in head and neck.
