复习１４例复发恶性骨肿瘤的临床、病理、Ｘ线资料。男１０例，女４例，年龄平均２７．８岁，骨肉瘤５例，骨巨细胞瘤３例，恶性纤维组织细胞瘤２例，软骨肉瘤３例，恶性骨母细胞瘤１例，通过分析发现复发的原因为：手术不彻底，术中没有按无瘤操作，手术前后没有及时、正确应用各种辅助治疗，复发常表现为：原手术部位疼痛或出现肿块，Ｘ线片示病变范围增大，瘤骨或瘤软骨形成或出现软组织肿块，ＥＳＲ和ＡＬＰ升高，复发后肿瘤的组织学类型无变化，但细胞的增殖能力较前增强，复发后若位于可完整切除的骨骼或周围软组织未受侵袭，可行保肢术；反之需行截肢或关节离断术。
Review the clinical, pathological and X-ray findings of 14 patients with recurrent malignant bone tumors. There were 10 males and 4 females with an average age of 27.8 years, 5 osteosarcomas, 3 giant cell tumors of bone, 2 malignant fibrous histiocytoma, 3 chondrosarcomas, and 1 malignant osteoblastoma. The reasons for the recurrence were: incomplete surgery, no tumor-free operation during surgery, no timely and correct application of various adjuvant treatments before and after surgery, and recurrence often manifested as pain or masses at the original surgical site, and X-ray films showed an increase in the extent of lesions. Large, tumor or cartilage cartilage formation or soft tissue mass, increased ESR and ALP, no change in the histological type of tumor after recurrence, but the cell’s proliferative capacity is stronger than before, if it is located in the bone or surrounding soft tissue can be completely resected after recurrence. Uninvasive, viable limb salvage surgery; otherwise need to amputation or joint dissect.
