据各家报导骨肉瘤存活率只有10-20％。本文就骨肉瘤多种形式治疗的活检前及术前照射作了介绍。并就免疫学方面作了粗略的讨论。 1971年5月-1976月1月期间,作者对6例发生在长管骨的骨肉瘤患者采用了活检前、术前照射以及手术与化疗联合方法。其中5例作了活检前的照射,全部病例均接受了术前照射。活检前照射之剂量有4例给1,000拉得,1例1,500拉得;术前照射有3例给了3000拉得,1例3,200拉得,2例4,500拉得。随病理确诊之后,术前照射对于肿瘤均给予宽大的边缘,除病例5之外都没有作全骨照射。大
According to reports, the survival rate of osteosarcoma is only 10-20%. This article describes the preoperative and preoperative irradiation of various forms of osteosarcoma treatment. And made a cursory discussion on immunology. Between May 1971 and January 1976, the authors used biopsy, preoperative irradiation, and a combination of surgery and chemotherapy for 6 patients with osteosarcoma who developed long tubular bones. Among them, 5 cases were irradiated before biopsy, and all cases received preoperative irradiation. Prior to biopsy, 4 doses were given to 1,000 pulls and 1 to 1,500 pulls; 3 were given 3000 pulls before surgery, 3,200 pulled in 1 case, and 4,500 pulled in 2 cases. After diagnosis with pathology, the preoperative irradiation gave a wide margin to the tumor, and no whole bone irradiation was performed except case 5. Big
