PURPOSE: We propose to study a group of @entity1 with primary @entity79 of the pelvis treated with limb salvage surgery and analyze overall survival, local recurrence rates and functional outcomes. METHODS: A retrospective review was performed, and all @entity1 diagnosed with pelvic primary @entity79 between 1990 and 2012 were analyzed. @entity1 treated with limb salvage surgery and with a minimum of 12-month follow-up for @entity1 alive were included. The overall survival and the local recurrence rate were calculated for the assessment of oncological results. The associations with gender, age, histological grade, type of surgery, margins chemotherapy response and use of navigation were examined. RESULTS: Fifty-two @entity1 were included in the study. The mean age was 37  years (range 10-82), and mean follow-up was 44  months (range 8-189). Forty-five (86  %) @entity5 were histologically classified as high-grade @entity242 , four (8  %) as low-grade @entity242 and three (6  %) as dedifferentiated @entity242 . Cancer-specific overall survival was 37.5  % for 5  years and 31  % for 10  years. Local recurrence rate was 30  %. High-grade @entity5 and chemotherapy necrosis below 90  % were negative prognosis factor. @entity260 rate was 34.5  % (n:18), being deep infection the most prevalent (n:13). Reconstruction of the pelvis after an oncology resection for primary @entity530 increased the incidence of complication significantly (p  <  0.001). CONCLUSION: Primary @entity79 involving the pelvis are suggestive of a high-grade @entity5 and present poor oncologic outcomes. Pelvic reconstruction after a limb salvage surgery is associated with a high risk of complication. LEVEL OF EVIDENCE: Case series, Level IV.
