A review of 33 patients with pyriform sinus carcinoma, seen between September 1972 and September 1978, is done. Preoperative irradiation is done in seven patients, resulting in a 28% survival rate. Postoperative irradiation in 14 patients yields a 64% survival rate. The average follow-up is 39.2 months. Survival is unaffected by the factor of geographic center of the tumor origin. Irradiation alone is done, mainly in patients who are inoperable or refuse surgery. There is a poor survival rate.
对1972年9月至1978年9月期间收治的33例梨状窦癌患者进行了回顾性研究。7例患者接受了术前放疗，生存率为28%。14例患者接受了术后放疗，生存率为64%。平均随访时间为39.2个月。肿瘤起源的地理中心因素不影响生存率。主要对无法手术或拒绝手术的患者单独进行放疗，生存率较低。
