Staging of carcinoma of the base of the tongue according to the system adopted by the American Joint Committee on Cancer relies on clinical examination possibly augmented by multiple biopsies. Palpation of the tongue base can be difficult without anaesthesia due to retching and vomiting. Computed tomography can, however, accurately depict the deep structures of the base of the tongue without discomfort to the patient. It can also demonstrate the nodal stations of the neck. In 12 patients with primary carcinoma of the base of the tongue the clinical staging results were compared with the CT findings. In 10 of the 12 patients there was good correlation between tumour size and location, while only 2 patients showed a 1.0-1.5 cm discrepancy in the size estimate of the primary tumour. A total of 9 enlarged lymph nodes or nodal groups were only found by CT. The majority of positive nodal stations demonstrated only by CT were in the contralateral neck. Computed tomography is a valuable complement when staging tongue base carcinomas, particularly when evaluating the neck for lymph node metastasis.
根据美国癌症联合委员会采用的系统对舌根癌进行分期，主要依靠临床检查，可能还需多次活检辅助。由于恶心和呕吐，在没有麻醉的情况下触诊舌根会很困难。然而，计算机断层扫描（CT）能够准确描绘舌根的深部结构，且不会给患者带来不适。它还能显示颈部的淋巴结站位。对12例原发性舌根癌患者的临床分期结果与CT检查结果进行了比较。12例患者中有10例肿瘤大小和位置的相关性良好，而只有2例患者的原发肿瘤大小估计存在1.0 - 1.5厘米的差异。CT总共发现了9个肿大的淋巴结或淋巴结组。仅通过CT显示的大多数阳性淋巴结站位位于对侧颈部。计算机断层扫描在舌根癌分期时是一种有价值的辅助手段，尤其是在评估颈部有无淋巴结转移时。
