We aimed to investigate the predisposing factor for lymph node metastasis and examine the influence of thickness for lymph node recurrence in oral tongue cancer.
We analysed 254 patients with early oral tongue cancer (T1-2N0) who were treated with brachytherapy from 1967 through 1985.
T category (p = 0.005), and thickness (p = 0.04) were identified as a significant predisposing factors for neck failure. 50%, 40% and 30% were the incidences of lymph node metastasis for patients with thickness of tumor more than 11 mm, 6-10 mm and 5 mm or less. Furthermore, T category (largest diameter of lesion) correlates strongly to thickness of tumor.
Although it is not an independent factor, thickness is a significant predisposing factor for lymph node metastasis.
我们旨在研究口腔舌癌淋巴结转移的易感因素，并探讨肿瘤厚度对淋巴结复发的影响。
我们分析了1967年至1985年间接受近距离放射治疗的254例早期口腔舌癌（T1-2N0）患者。
T分类（p = 0.005）和肿瘤厚度（p = 0.04）被确定为颈部治疗失败的重要易感因素。肿瘤厚度超过11mm、6-10mm和5mm及以下的患者，其淋巴结转移发生率分别为50%、40%和30%。此外，T分类（病变最大直径）与肿瘤厚度密切相关。
虽然肿瘤厚度不是一个独立因素，但它是淋巴结转移的重要易感因素。
