Functional outcomes and quality of life in patients with osteosarcoma treated with amputation versus limb-salvage surgery: a systematic review and meta-analysis.

INTRODUCTION

To perform a meta-analysis for comparing the functional outcomes and quality of life (QOL) of osteosarcoma patients receiving amputation or limb-salvage surgeries.

MATERIALS AND METHODS

A search was conducted of the Medline, Cochrane, EMBASE, and Google Scholar on September 30, 2013. Studies were included in the analysis if there were patients who underwent amputation and limb-salvage surgery for osteosarcoma or Ewing's sarcoma, and for whom postoperative functional outcomes and QOL were evaluated. Outcomes were compared between participants who underwent limb-salvage operation and those who underwent amputation. The methodological quality of non-randomized comparative studies was assessed using the Newcastle-Ottawa Scale.

RESULTS

A total of 121 studies were identified and 6 were included in the meta-analysis. Quality assessment indicated that all six studies were of high quality. The mean age of the participants ranged from 17 to 37 years, and among them 118 underwent amputations and 138 underwent limb-salvage procedures. The mean length of follow-up ranged from 28 to 145 months. The meta-analysis indicated that functional outcomes and QOL were similar between patients who underwent amputation and those who underwent a limb-salvage procedure.

CONCLUSIONS

This meta-analysis including six high-quality studies indicates that amputation and limb-salvage surgery provide similar functional outcomes and quality of life for patients with osteosarcomas.
