对尤文氏瘤的治疗,过去都单独使用外科手术或放疗,或二者合用,所得5年生存率,各家报导介于5～45%之间。治疗失败的主要原因在于无法控制早期就存在的,全身性亚临床转移,治疗中合并加用化疗理应有所裨益。MD.Anderson医院自1948～1975年底,共收治76例早期尤文氏瘤。根据年代的推移和治疗手段的改变,可依次序划分为四组分析,即: 第Ⅰ组为1948～1964年所治的25例,单用放疗,使用250KV和/或钴60照射患瘤全骨,剂量达4100～6000拉得,27～41d完成,全量最后的15～20%缩小射野,集中照射肿瘤部位。第Ⅱ组为1964～1969年间治疗的15例,单用钴
For the treatment of Ewing’s tumor, surgical or radiotherapy alone or in combination with the two was used in the past. The 5-year survival rate was reported to be between 5 and 45%. The main reason for treatment failure lies in the inability to control the existence of systemic subclinical metastases in the early stages, and the addition of chemotherapy in combination with therapy should be beneficial. MD.Anderson Hospital had treated 76 cases of early Ewing’s tumor from the end of 1948-1975. According to the passage of time and the change of treatment methods, it can be divided into four groups of analysis, namely: the first group is 25 cases treated from 1948 to 1964, single-use radiotherapy, using 250KV and/or cobalt 60 irradiation to cure the tumor Bone, the dose of 4100 ~ 6000 pull, 27 ~ 41d to complete the entire 15 ~ 20% of the final reduction of the field, focused on the tumor site. Group II is 15 cases treated between 1964 and 1969. Cobalt alone
