Ewing肉瘤(尤文肉瘤)是骨科少见的一种高度恶性低分化的小圆细胞原发骨肿瘤。对青少年的危害极大,目前在诊断与治疗上存在不少问题,在治疗方法上有颇多争议。本文通过9例Ewing肉瘤的诊治提出了长管状骨及扁平骨Ewing肉瘤的特征及诊断方法。减少了误诊率;同时对其治疗提出术前全身化疗、术中局部化疗、术后化疗加放疗的综合治疗方案,以减少肿瘤复发及转移机率,为保存患肢功能,提高病人5年存活率,我们认为这是一种治疗Ew-ing氏肉瘤的有效方案。
Ewing sarcoma (Ewing’s sarcoma) is a highly malignant poorly differentiated small round cell primary bone tumor rare in orthopaedics. The harm to adolescents is enormous. At present, there are many problems in diagnosis and treatment, and there are many disputes in the treatment methods. In this paper, the diagnosis and treatment of Ewing sarcoma with long tubular bone and flat bone are presented in the diagnosis and treatment of 9 cases of Ewing sarcoma. Reduce the misdiagnosis rate; At the same time, propose a comprehensive treatment plan of preoperative systemic chemotherapy, intraoperative local chemotherapy, postoperative chemotherapy plus radiotherapy to reduce the probability of tumor recurrence and metastasis, to preserve the limb function and improve the patient’s 5-year survival rate. We think this is an effective treatment for Ew-ing’s sarcoma.
