Abstract
Introduction: The aim of this meta-analysis was to further explore whether the relapse, 5-year survival and metastasis the same or not between limb-salvage and amputation in the treatment of patients with limited stage Enneking‡U pathologic fracture osteosarcoma. Materials and Methods: An electronic search of the Medline, EMBASE and CNKI was done on October 2014. The clinical studies about amputation or limb-salvage surgery in the treatment of patients with limited stage Enneking‡U pathologic fracture osteosarcoma were searched and reviewed. The effect size of relapse, 5-year survival and metastasis between the amputation and limb-salvage surgery were pooled by stata11.0 software (Stata Corporation, College Station, TX, USA, https://www.stata.com;) using random or fixed effect model. The funnel plot and Egger's line regression test were used for evaluation of publication bias. Results: A total of 89 studies were identified and seven articles with 200 cases in the limb-salvage surgery group and 84 subjects in the amputation group were finally included in the meta-analysis. The pooled data indicated that no statistical different of risk for developing relapse between limb-salvage and amputation was found relative risk (RR) =1.40, 95% confidence interval (CI): 0.71-2.79, (P = 0.33). The 5-year survival rate of patients underwent limb-salvage surgery was smaller than patients received amputation RR = 1.86, 95%CI: 1.19-2.89, (P = 0.01); the metastasis rate of patients underwent limb-salvage surgery was significant decreased compared with patients received amputation RR = 0.56, 95% CI: 0.34-0.94, (P = 0.03). No publication bias was existed in this meta-analysis. Conclusion: Limb-salvage surgery does not increased the risk of relapse compared with amputation in the treatment of patients with limited stage Enneking‡U pathologic fracture osteosarcoma.
