OBJECTIVETo explore 5-year survival rate, local recurrence and metastasis rate of limb salvage and amputation for patients with local Enneking II osteosarcoma by Meta-analysis.

METHODSFrom January 1, 1970 to December 1, 2015, Subject term and keywords about limb salvage and amputation for local Enneking II osteosarcoma with pathological fracture were searched from Cochrane, PubMed, Ovid, Spinger Link, Embase, CNKI and WanFang database foundation. Literature confirm with inclusion criteria were choose and quality evaluation were performed. RevMan 5.0 software from Cochrane collaboration was used to perform Meta-analysis. Local recurrence, 5-year survival rate and odds ratio of transfer risk were compared between limb salvage and amputation group.

RESULTSTen literatures confirm with inclusion criteria were included, and total sample size was 453. There were 315 patients in limb salvage group and 138 patients in amputation group. Five-year survival rate in amputation group was lower than that of limb salvage group [OR=2.88, 95%CI(1.40, 5.93)], however metastasis rate in limb salvage was less than that of amputation group [OR=0.43, 95%CI(0.20, 0.94)];there were no significant differences in local recurrence between two groups [OR=1.47, 95%CI (0.73, 2.97)]. Functional rehabilitation in limb salvage group was better than that of amputation group by MSTS systematic review.

CONCLUSIONSLimb salvage as an alternative in treating local Enneking II osteosarcoma with pathological fracture does not greatly increase risk of local recurrence or 5-year overall survival rate compared with amputation group, and has a lower risk of metastatic occurrence.
