口咽部肿瘤很少局限于一个部位,要确定肿瘤的原发部位常较困难,由于口腔后部之诸结构都属于同一组淋巴引流,且治疗效果相仿,故建议在考虑治疗时,把扁桃体和舌根部鳞癌归于一类。作者们从1969年到1975年治疗145例扁桃体和舌根部鳞癌,五年生存率为42％。以往普遍认为该区域鳞癌处理困难,细胞分化很差,容易转 Oropharyngeal tumors are rarely confined to one site, and it is often difficult to determine the primary site of the tumor. Since the structures of the posterior oral cavity belong to the same group of lymphatic drainage and the therapeutic effects are similar, it is recommended that the tonsils be considered when the treatment is considered.

In the past, it was generally believed that squamous cell carcinoma in this region was difficult to handle, cell differentiation was poor, and it was easy to turn
