目的： 分析长骨骨巨细胞瘤相关复发因素， 为其临床治疗及降低复发率提供参考依据． 方法： 分析２１例长骨复发性骨巨细胞瘤一般资料、影像学检查资料、首次手术方式、肿瘤所在部位、病理骨折与否、Ｊａｆｆｅ＇ｓ 病理分级、Ｃａｍ ｐａｎｉｃｃｉ＇ｓ放射线分级等， 总结相关的复发因素． 结果： 本组４１例肿瘤中复发者２１例． ２１例中Ｊａｆｆｅ＇ｓ病理诊断与首次比较， １７例无变化； 按Ｃａｍ ｐａｎｉｃｃｉ＇ｓ放射诊断标准， 首次１９例为Ⅱ， Ⅲ级． １２例位于胫骨近端； １１例首次术前即伴局部病理性骨折， 占５２．４％ ． 所有病例均被施予单纯瘤内刮除术， ７例肿瘤残腔经烧灼等辅助处理． 结论： 长骨骨巨细胞瘤复发相关因素复杂多样， 肿瘤复发与Ｊａｆｆｅ＇ｓ 病理分级无明显相关； 但Ｃａｍ ｐａｎｉｃｃｉ＇ｓ分级越高， 则复发率越高； 局部病理性骨折是导致复发的重要原因； 单纯瘤内刮除术可致较高比例的肿瘤复发， 而相关的烧灼瘤壁等辅助治疗措施， 不能替代彻底的肿瘤切除术．
Objective: To analyze the related recurrence factors of giant cell tumor of long bone and provide reference for clinical treatment and reduce the recurrence rate. Methods: Analysis of 21 cases of recurrent giant bone cell tumors of the bone, general information, imaging examination data, first surgical methods, location of the tumor, pathological fractures, Jaffe’s pathological grade, Campecine’s radiographic grading, etc. Recurrence factors. 3. Results: There were 21 cases of recurrence in 41 cases in this group. In 21 cases, Jaffe’s pathological diagnosis was compared with the first time. There was no change in 17 cases. According to Camp panicci’s diagnostic criteria, the first 19 cases were grade II and III. Twelve cases were located in the proximal humerus; 11 cases had local pathological fracture before surgery for the first time, accounting for 52.4%. All cases were treated with simple intralesional curettage, and 7 cases were treated with cauterization. Conclusions: The factors associated with the recurrence of giant cell tumors of the long bone are complex and diverse, and there is no significant correlation between tumor recurrence and Jaffe’s pathological grade, but the higher the Campanic’s grade, the higher the recurrence rate; Local pathological fractures are important causes of recurrence. Intralesional curettage results in a higher proportion of tumor recurrences, and associated adjuvant measures such as cauterizing tumor walls are not a substitute for thorough tumor resection.
