骨肉瘤截肢后的复发率各家报告不同,低的为3-4%,高的达16%,后者可能将局部复发与残端骨转移混淆。作者报告截肢或关节离断处理的248例高度恶性(3-4级)的骨肉瘤,有13例(5.2%)局部复发。复发时间自术后2月～7年,平均12个月。复发可广泛侵犯骨与软组织,或仅局限于骨或软组织,后者用X 线照片不易诊断。对局部复发的肿瘤尽可能用手术处理,放射疗法可减轻症状,但预后不良。本组死亡11例,复发后生存时间平均8个月。复发的原因可能是:截肢平面距肿瘤太近;肿瘤
The recurrence rate of osteosarcoma after amputation was reported by different people, with a low of 3-4% and a high of 16%. The latter may confuse local recurrence with stump bone metastases. The authors reported 248 high-grade (grade 3-4) osteosarcomas treated with amputation or disarticulation, and 13 (5.2%) had local recurrence. The recurrence time was from 2 months to 7 years after surgery, with an average of 12 months. Recurrence can be widespread violations of bone and soft tissue, or limited to bone or soft tissue, the latter easy to diagnose with X-ray photographs. For locally reoccurring tumors, surgical treatment should be used as much as possible. Radiation therapy can relieve symptoms but has a poor prognosis. Eleven patients died in this group, and the average survival time after relapse was 8 months. The reason for the recurrence may be: the amputee plane is too close to the tumor; tumor
