０引言骨巨细胞瘤（ＧＣＴ）是有较强局部侵袭性的原发性骨肿瘤．局部病灶刮除，５００ｇ／Ｌ氯化锌溶液烧灼瘤腔壁＋植骨治疗，术后仍有一定的复发率，Ｊａｆｆｅ病理分级对其复发与否无预后指导意义．近来研究表明，肿瘤的发生及生物学特性与其增殖和调亡有密切关系［１，２?
0 Introduction Giant cell tumor of the bone (GCT) is a strongly localized invasive primary bone tumor. Local lesion curettage, 500g/L zinc chloride solution burn cavity wall + bone graft treatment, there is still a certain recurrence rate after operation, Jaffe pathological grade has no prognostic significance for its recurrence or not. Recent studies have shown that the occurrence and biological characteristics of tumors are closely related to their proliferation and apoptosis [1, 2?
