下咽癌病灶解剖部位与肿瘤复发,特别是颈部复发有着密切关系。回顾1975～1986年间外科治疗的169例下咽癌资料,病人随访至少3 年或直至死亡。下咽分为咽后壁(PW)、环后区(PC)、梨状窝外侧壁(LP)及梨状窝内侧壁(MP)四部分,后者包括边缘区域(杓会皱襞、披裂、会厌咽皱襞)。169例病人就诊时颈淋巴结肿大者占67％,LP病人76例(45％),MP病人71例(42％),PW21例(12％)及PC1例(1％)。Ⅱ期患者17例(10％),Ⅲ期42例(25％),Ⅳ期110例 The anatomical site of hypopharyngeal cancer lesions has a close relationship with tumor recurrence, especially neck recurrence. Review 169 cases of hypopharyngeal cancer surgically treated between 1975 and 1986. Patients were followed for at least 3 years or until death. The hypopharynx is divided into the posterior pharyngeal wall (PW), the posterior ring area (PC), the lateral wall of the sacral fossa (LP), and the inner side wall (MP) of the pyriform sinus (MP). The latter includes the marginal area. The epiglottis pharynx. Of the 169 patients, 67% had cervical lymphadenopathy, 76 had LP (45%), 71 had MP (42%), 21 had PW (12%), and 1 had had PC (1%). 17 patients (10%) in stage II patients, 42 patients (25%) in stage III, 110 patients in stage IV
