青年原发性恶性骨巨细胞瘤Ⅲ级病灶内切除与整块切除治疗的对比研究

Control Study of The Youth With The Third Grade Primary Malignant Giant Cell Tumor of Bone After Intralesional Excision Or En Bloc Resection

目的：研究青年原发性恶性骨巨细胞瘤Ⅲ级病灶内切除与整块切除治疗行走恢复及复发的情况。方法：将研究对象青年原发性恶性骨巨细胞瘤患者按照治疗方式分为两组：A组是整块切除治疗，B组进行病灶内切除治疗。比较青年患者的行走恢复及复发情况。结果：病灶内切除治疗的青年恶性肿瘤患者的各项指标差于整块切除治疗的青年患者，结果具有统计学意义（x^2=4．31；P〈0．05）。结论：青年原发性恶性骨巨细胞瘤Ⅲ级患者最佳的方式是进行整块切除治疗。
