梨状窝的鳞癌治愈率低。其临床症状出现较晚,且易发生区域淋巴结转移。本文旨在探讨其存活期和疾病分期及治疗方法的相互关系,以便选择最有效的疗法。作者对102例梨状窝鳞癌中资料完整的87例进行分析。全部病例至少随访5年。平均年龄59岁,男性84%,女性16%。按AJCC(1978)分期:Ⅳ期46例,Ⅲ期28例,Ⅱ期12例,Ⅰ期1例。原发灶分期是T_16例,T_2 29例.T_3 48例.T_44例。初诊65例(750%)临床颈淋巴结转移,其中N_1 21例,N_2 27例,N_3 17例。
The cure rate of squamous cell carcinoma in the pear-shaped fossa is low. The clinical symptoms appear later and regional lymph node metastases are prone to occur. This article aims to explore the interrelationship between survival, disease stage, and treatment methods in order to select the most effective therapy. The authors analyzed the complete data of 87 cases of squamous cell carcinoma of the piriform fossa. All cases were followed for at least 5 years. The average age is 59 years, 84% for men and 16% for women. According to the AJCC (1978) stage, there were 46 cases of stage IV, 28 cases of stage III, 12 cases of stage II, and 1 case of stage I. The primary tumor stage was T_16 cases, T_2 29 cases, T_3 48 cases, T_44 cases. Of the newly diagnosed patients, 65 (750%) had clinical cervical lymph node metastases, of which 21 were N_1, 27 were N_2, and 17 were N_3.
