作者选用64例诊断为肉瘤的病例,系每周6.6Gy肿瘤剂量,整个疗程分割4—7次的大分割或低分割方法。全部病例分2组。A组37例,均带有肉眼可见的肿瘤,效果可以直接判断。其中29例是对原发灶治疗,另8例是针对转移灶。B组27例,为软组织肉瘤术后放疗,观察的主要指标为局部复发。60％的病灶在肢体和腰带,60％照射时需包括较小体积的肺,1例照射全脑。大多数病例采用平行对穿野,6例是单野,2例使用楔形板。作者见到,A组12例无效,治疗期间仍有肿瘤生长,12例肿瘤无变化,只有8例获得部分疗效。70％治疗期间有转移,这组平均存活时间为12个月。B组只有
The authors used 64 cases of sarcoma diagnosed, a weekly 6.6Gy tumor dose, the entire course of separation divided 4-7 times the large or low segmentation method. All cases were divided into 2 groups. A group of 37 cases, all with macroscopic tumors, the effect can be directly judged. Of these, 29 were primary lesions and 8 were metastases. In group B, 27 cases were postoperative radiotherapy for soft tissue sarcoma. The main index observed was local recurrence. 60% of the lesions were in the limbs and belts, 60% were irradiated with a smaller volume of lung, and 1 was irradiated with whole brain. In most cases, parallel pairs were used, 6 were single, and 2 were wedge plates. The authors observed that 12 patients in group A were ineffective, and tumors continued to grow during treatment. There were no changes in 12 tumors. Only 8 patients received partial efficacy. There was metastasis during the 70% treatment period, and the average survival time was 12 months in this group. Group B only
