以前,肢体骨肉瘤和软组织肉瘤的预后是很差的,常需行截肢术。近年肢体肉瘤的治疗有了很大进展。软组织肉瘤术后五年存活率达70～80%,骨肉瘤达50～60%;而且有些病例可保留肢体,局部复发率与截肢者相近,小于10%。这些进展与病理学、放射诊断、化疗、放疗等方面的进展有关。例如病理分类进一步完善。放射诊断方面,CAT(计算机体层 X 线照相)的应用,对肺转移瘤的发现率较 X线胸片、X 线体层照相分别提高30%和10%。CAT 扫描能确定肿瘤的三维空间
Previously, the prognosis of limb osteosarcoma and soft tissue sarcoma was very poor, and amputation was often required. In recent years, the treatment of limb sarcoma has made great progress. The five-year survival rate of soft tissue sarcoma is 70-80%, and osteosarcoma is 50-60%. In some cases, limbs can be preserved. The local recurrence rate is similar to that of amputees and less than 10%. These advances are related to progress in pathology, radiation diagnosis, chemotherapy, and radiotherapy. For example, pathological classification is further improved. In radiological diagnosis, the use of CAT (computerized tomography) has increased the detection rate of lung metastases by 30% and 10% compared with X-ray and X-ray. CAT scan can determine the three-dimensional space of tumor
