作者选用了原发或复发并且尚无临床或X 线照片证明有远处转移的软组织肉瘤进行放疗的病例,共51例。均未进行根治性切除术,术后仍残存瘤块。年龄4-96岁,男30例,女21例,纤维肉瘤8例,脂肪肉瘤7例。除少数外,治疗是180-200cGy/次,5次/周,总剂量6400—6600cGy,不同分割的剂量当量用Orton 和Ellis 的公式计算。51例中37例(72%)进行了5年以上随访,44例随访4年。11例无瘤存活。28例局部控制失败,其中20例伴有远处转移。10例只有远处转移,2例死于间发病。五年存活率25.1%,局部控制率33%。当剂量相当于或超过6400cGy、200
The authors selected primary or recurrent cases and had no clinical or radiographic evidence of distant metastatic soft tissue sarcomas for radiotherapy in 51 cases. No radical resection was performed, and tumors remained after surgery. Age 4-96 years old, 30 males and 21 females, 8 cases of fibrosarcoma, 7 cases of liposarcoma. Except for a few, the treatment was 180-200 cGy/time, 5 times/week, and the total dose was 6400-6600 cGy. The dose equivalents of different segments were calculated using the formula of Orton and Ellis. Of the 51 patients, 37 (72%) were followed for more than 5 years and 44 were followed for 4 years. 11 cases survived without tumor. 28 cases of local control failed, of which 20 cases had distant metastases. Only distant metastases occurred in 10 cases, and 2 cases died of interictal disease. The five-year survival rate is 25.1%, and the local control rate is 33%. When the dose is equal to or more than 6400cGy, 200
