用化学疗法治疗骨肉瘤大大改变了该病的预后。此外,肢体挽救手术亦使肢体的功能得以保存。由于对不同的组织学类型需采用不同的方法来治疗,故骨肉瘤的分类就显得愈为重要(见表1) Raymond等提出一种分类方法,旨在强调该肿瘤的常见组织成分(见表2) 骨肉瘤可有不同的X线表现,呈完全性溶骨性改变的可能为毛细血管扩张型骨肉瘤,但从放射学上不能与具典型组织学改变的溶骨性骨肉瘤相区别。放射学诊断取决于异常的骨反应,即病变是否均匀、规则,界限清晰抑或缺乏边界,皮质反应的性质,病变周围有否软组织肿块等诸多因素。
Treatment of osteosarcoma with chemotherapy significantly changes the prognosis of the disease. In addition, limb salvage surgery also preserves the function of the limb. Since different histological types need to be treated in different ways, the more important it is to classify osteosarcomas (see Table 1) Raymond et al. propose a classification method designed to emphasize the common tissue components of the tumour (see table). 2) Osteosarcoma may have different X-ray appearances. The complete osteolytic change may be telangiectasia osteosarcoma, but it cannot be radiologically distinguished from osteolytic osteosarcoma with typical histological changes. Radiological diagnosis depends on an abnormal bone reaction, that is, whether the lesion is uniform, regular, the boundary is clear or lack of borders, the nature of the cortical response, there are many factors such as soft tissue mass around the lesion.
