大多数鼻咽癌(NPC)对放疗敏感,原发病灶治疗后常消失,但随着诊疗技术的提高,对NPC的范围有更加精确的评价。作者自1982年以来对NPC患者首用放疗,治疗后CT扫描随访发现在作60Gy放疗后NPC并不总是消失,甚至在鼻内窥镜和纤维镜下未见残余肿瘤者,CT扫描亦有肿瘤残留征象。在1985年2月和1990年1月对这些残余肿瘤患者经下颌骨、翼突进路行根治术。5例NPC患者中男4例女1例,年龄40～68岁,临床分期T_2N_(2C)2例,T_3N_02例,T_3N_(2C)1例,病理分型鳞癌4例,囊性腺样癌1例。并以此术式作了1例鼻咽部到咽旁
Most nasopharyngeal carcinomas (NPCs) are sensitive to radiotherapy, and the primary lesions often disappear after treatment. However, with the improvement of diagnosis and treatment techniques, there is a more accurate assessment of the scope of NPC. The authors have used radiotherapy for NPC patients for the first time since 1982. Follow-up CT scans after treatment found that NPC did not always disappear after 60 Gy radiotherapy. No residual tumors were seen under nasal endoscope and fiberscope. CT scans were also available. Residual tumor sign. In February 1985 and January 1990, patients with these residual tumors underwent radical resection of the mandible and pterygoid approach. Among the 5 NPC patients, 4 were male and 1 female, aged 40-68 years. Clinical staging T_2N_(2C) 2 cases, T_3N_02 cases, T_3N_(2C) 1 case, pathological type 4 squamous cell carcinoma, cystic adenoid carcinoma 1 example. A case of nasopharyngeal to the pharyngeal was made with this operation
