摘　　要：目的探讨下肢肿瘤切除后使用非骨水泥组配式人工关节重建的初步疗效,分析假体失败的影响因素。方法回顾分析2011年10月—2016年9月使用MEGASYSTEM-C非骨水泥组配式肿瘤型假体系统治疗的150例下肢肿瘤患者临床资料。男88例,女62例;年龄12~81岁,中位年龄24岁。根据世界卫生组织(WHO)骨肿瘤分类:骨原发恶性肿瘤120例,中间型肿瘤27例,转移性肿瘤3例。134例为初次手术,16例为复发后再次手术。87例恶性肿瘤患者手术前后行化疗,无患者行围术期局部放疗。假体重建股骨近端32例,股骨远端83例,胫骨近端35例。记录患者术后随访时间;肿瘤学结果,包括患者生存状况、肿瘤复发状况;假体失败发生情况,包括假体生存率、假体失败情况(失败原因、失败后再治疗方案)等,假体失败原因根据Henderson等定义的分型方式分为5型。采用Kaplan-Meier生存分析及Log-Rank检验分析患者及假体生存率。末次随访时根据肌肉骨骼肿瘤协会(MSTS)评分系统评估患者下肢功能,并比较不同重建部位患者的MSTS评分。结果 150例患者术后均获随访,随访时间5~84个月,中位时间39个月。随访期内患者无瘤存活116例,带瘤存活10例,因肺转移或多发转移死亡24例。120例原发恶性肿瘤患者3、5年生存率分别为83.1%、76.6%;不同重建部位患者生存率比较差异无统计学意义(P=0.851)。7例(4.7%)于术后7~21个月局部复发。150例患者假体3、5年生存率分别为94.4%、92.5%;不同重建部位假体生存率比较差异无统计学意义(P=0.765)。随访期间共24例(16.0%)患者发生26次假体失败,其中1型失败9例、2型1例、3型3例、4型5例、5型8例。末次随访时126例存活患者中120例无假体失败发生。除不同重建部位对4型失败发生率的影响有统计学意义(P=0.029),是否化疗对5型失败发生率的影响有统计学意义(P=0.002)外,其余各型失败发生率与不同重建部位、是�Objective To report the preliminary clinical results and analyze the prognostic factors of prosthetic failures with non-cemented modular prosthetic reconstruction after tumor resection in lower extremities. Methods A clinical data of 150 patients with lower extremity tumors treated with MEGASYSTEM-C non-cemented modular prosthetic reconstruction between October 2011 and September 2016 was retrospectively analyzed. There were 88 males and 62 females, aged from 12 to 81 years, with a median age of 24 years. According to World Health Organization (WHO) classification of bone tumors, 120 cases were primary malignant tumors, 27 cases were intermediate tumors, and 3 cases were metastatic tumors. Among them, 134 cases underwent primary operation and 16 cases underwent reoperation after recurrence. Eighty-seven patients with malignant tumors received chemotherapy before and after operation, and no patient received local radiotherapy during perioperative period. Proximal femur was reconstructed in 32 cases, distal femur in 83 cases, and proximal tibia in 35 cases. The postoperative follow-up time, the results of oncology (survival status and tumor recurrence), and prosthesis failure (prosthesis survival rate, reasons for failure, treatment plan after failure) were recorded. The reason of the prosthesis failure was classified into 5 types according to the classification defined by Henderson et al. Kaplan-Meier survival analysis and Log-Rank test were used to analyze patient and prosthesis survival. Lower extremity function was assessed by using the Musculoskeletal Tumor Society (MSTS) scoring system and MSTS scores were compared for patients with different reconstruction sites. Results All patients were followed up 5-84 months, the median follow-up time was 39 months. During the follow-up period, there were 116 cases of tumor-free survival, 10 cases of tumor-bearing survival, and 24 died of lung metastasis or multiple metastases. The 3-year and 5-year survival rates of 120 patients with primary malignant tumors were 83.1%
