UNASSIGNED: The objective of the study was to analyze a group of @entity1 with low grade @entity421 treated with limb salvage surgery and reconstructed with bone allograft. A retrospective review from our oncologic data base between 1980 and 2010 was done and all @entity1 with diagnosis of low grade @entity421 , treated with limb salvage surgery and reconstructed with allograft were included. Twenty-two @entity1 were included for the analysis. The mean age was 32    11 years (10-59) y the mean follow-up 93    69 months (8-237). Ten year overall survival of the series was 91% (95% CI: 79-100). Four @entity1 developed local recurrence, 2 of them histological classified after the resection dedifferentiated @entity421 . Two @entity1 developed distant recurrence, being the lung the only site of @entity3 . Ten year limb salvage reconstruction survival was 65% (95% CI: 44-86). Long term survival rate in low grade @entity421 is over 90%. Surgical resection wide margin should be the elective treatment and biological limb salvage reconstruction is a good alternative.
