Background:Limb-sparing resection and reconstruction for pelvic sarcomas in multiple small studies have been fraught with complications, reoperations, and impaired patient function. However, the non-oncologic complication and reoperation rates and functional outcomes for patients have never been rigorously compiled, to our knowledge. A systematic review was undertaken to more accurately determine the non-oncologic complication and reoperation rates and functional outcomes for patients after pelvic sarcoma resection and reconstruction.Methods:The review was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed and Cochrane database searches of English-only studies using the terms “pelvis AND sarcoma” and “pelvis AND sarcoma AND surgery” were performed. Study inclusion criteria were ≥10 patients enrolled, at least 12 months of follow-up, utilization of comparable functional outcome measure(s), and the majority of the resections treating primary bone sarcoma.Results:In this study, 2,350 studies were reviewed, of which 22 Level-IV studies with a total of 801 patients met inclusion criteria. Reconstructive techniques varied widely and included allografts, allograft-prosthesis composites, saddle prostheses, custom endoprostheses, and irradiated autografts. Pooled means showed a mean 5-year patient survival of 55%. The mean non-oncologic complication rate was 49%. The mean non-oncologic reoperation rate was 37%. The mean Musculoskeletal Tumor Society score was 65%.Conclusions:The non-oncologic complication and reoperation rates for pelvic reconstructions are remarkably high and 5-year survival is poor. Functional outcomes are acceptable but may not be better than a resection of the same Enneking and Dunham type without reconstruction. Consideration should be given to forgoing pelvic reconstruction, especially in patients with poor overall prognosis. Further studies comparing non-oncologic complication rates, reoperation rates, and functional outcomes in patients with equivalent resections treated with or without reconstruction are needed to further elucidate the utility of pelvic reconstruction.Level of Evidence:Therapeutic Level IV.
