骨巨细胞瘤(GCT)是一种常见的骨肿瘤,我国GCT发病率占原发性骨肿瘤的20%,而西方国家只占5%。其有较强的局部侵蚀性,不良预后主要为局部复发,少数可发生肺转移。GCT的不良预后有很多不确定性,组织学分级没有评价意义[1]。其预后评价具有特殊性,现将近年的相关研究综述如下。一、 Giant cell tumor of bone (GCT) is a common bone tumor, the incidence of GCT in China accounted for 20% of primary bone tumors, while only 5% in Western countries. It has a strong local erosion, poor prognosis mainly for local recurrence, a few may occur lung metastases. There are many uncertainties in the adverse prognosis of GCT, histological grade did not evaluate the significance of [1]. The prognosis evaluation has its own particularity. Now the related research in recent years is summarized as follows. one,
