目的:比较原位微波消融与假体置换两种手术方法治疗四肢骨肿瘤的临床效果。方法:2008年1月至2012年2月,分别采用原位微波消融或肿瘤假体置换手术治疗四肢肿瘤40例,手术后1年,从肿瘤学、手术并发症、肢体功能三个方面进行对比。结果:平均随访26.5个月,微波消融组4例(4/30),假体置换组2例(2/10)死亡;肺转移2例,全部为假体置换组;复发5例,全部为微波消融组。微波消融组手术并发症发生率为15例,肿瘤假体置换组为2例。Enneking功能评分微波消融组12~28分,平均23分;假体置换组分17~29分,平均26分。结论:术后1年结果比较,两种治疗方法的总体生存率达到85%,均是可接受的保肢手术方法;微波消融组手术并发症高于假体置换组;假体置换组肢体功能优于微波消融组。
Objective: To compare the clinical effects of in situ microwave ablation and prosthesis replacement for the treatment of limb bone tumors. Methods: From January 2008 to February 2012, 40 cases of limbal tumors were treated with microwave ablation or tumor prosthesis replacement respectively. One year after operation, the comparison was made on three aspects of oncology, surgical complications and limb function . Results: After a mean follow-up of 26.5 months, there were 4 cases (4/30) in the microwave ablation group and 2 cases (2/10) died in the replacement group. Two cases were lung metastases, all of which were prosthesis replacement group. Microwave ablation group. The incidence of surgical complications in microwave ablation group was 15 cases and in 2 cases of tumor prosthesis replacement group. Enneking function score microwave ablation group 12 to 28 points, an average of 23 points; prosthetic replacement components 17 to 29 points, an average of 26 points. Conclusion: Compared with the results of one year after operation, the overall survival rate of both treatment methods is 85%, which is an acceptable method of limb salvage surgery. The complications of microwave ablation group are higher than that of prosthesis replacement group. Better than microwave ablation group.
