本文回顾分析1960～1976年治疗的61例梨状窝癌,其中男50例,女11例;平均年龄60岁,最小43岁,最大82岁;96.7%病例在诊断时已属晚期,即Ⅲ期21例,Ⅳ期38例,约75%病例有颈淋巴结转移,仅2例为Ⅱ期,故预后差:病理类型均是鳞癌。用~(137)铯或~(60)钴远距放射治疗,剂量为6040～7100rad,分30～43次在43～50天内完成;颈下段区域则在5周内给予5000rad。单纯高剂量放疗,原发灶控制率是:T_254.5%(6/11),T_3 43.3%(13/30),T_4无效(0/14);颈淋巴结控制率是:N_1 60%(6/10),N_2～N3 13.8%(4/29)。在原发灶肿瘤未能控制的37例中,有19例
This paper retrospectively analyzed 61 cases of pear-shaped nest cancer treated from 1960 to 1976, including 50 males and 11 females, with an average age of 60 years and a minimum of 43 years and a maximum of 82 years. 96.7% of cases were already diagnosed with advanced stage III 21 cases of stage, 38 cases of stage Ⅳ, about 75% cases of cervical lymph node metastasis, only 2 cases of stage Ⅱ, so the prognosis is poor: the pathological types are squamous cell carcinoma. With ~ (137) cesium or ~ (60) cobalt long-range radiation therapy, the dose of 6040 ~ 7100rad, 30 to 43 times in 43 to 50 days to complete the lower cervical region was given within 5 weeks 5000rad. The control rate of primary tumor was T_254.5% (6/11), T_3 43.3% (13/30), T_4 ineffective (0/14). The control rate of neck lymph node was: N_1 60% (6 / 10), N_2 ~ N3 13.8% (4/29). Of the 37 patients with primary tumor that failed to be controlled, 19 were present
