Bilateral Renal Auto-Transplantation for Retroperitoneal Sarcomas: Is It Underutilized?. Curr Oncol. 2023;30(8):7620-7626. Published 2023 Aug 14. doi:10.3390/curroncol30080552https://hdl.handle.net/1805/38609Sarcomas are a rare tumor of mesenchymal origin. The liposarcoma is the most common sarcoma of the retroperitoneum. Liposarcomas are typically low grade, and present at an advanced stage and a large size. We report a case of a large retroperitoneal liposarcoma, approximately 50 kg, encasing both kidneys, which was managed via a two-stage resection and staged renal auto-transplantation into the intra-peritoneal pelvis. The patient maintained normal renal function throughout, and remains disease free two years post-resection. Renal auto-transplantation with pelvic placement may facilitate improved margin-free resection. Renal relocation may allow the use of curative-intent ablative therapies such as radiofrequency ablation and radiation in cases of retroperitoneal recurrence.en-USAttribution 4.0 InternationalTransplantationAuto-transplantationRetroperitoneal sarcomaSarcomaCancerArticle
