Item Ablative Therapy in Non-HCC Liver Malignancy(MDPI, 2023-02-14) Robinson, Tyler P.; Pebror, Travis; Krosin, Matthew E.; Koniaris, Leonidas G.; Surgery, School of MedicineSurgical extirpation of liver tumors remains a proven approach in the management of metastatic tumors to the liver, particularly those of colorectal origin. Ablative, non-resective therapies are an increasingly attractive primary therapy for liver tumors as they are generally better tolerated and result in far less morbidity and mortality. Ablative therapies preserve greater normal liver parenchyma allowing better post-treatment liver function and are particularly appropriate for treating subsequent liver-specific tumor recurrence. This article reviews the current status of ablative therapies for non-hepatocellular liver tumors with a discussion of many of the clinically available approaches.Item Bilateral Renal Auto-Transplantation for Retroperitoneal Sarcomas: Is It Underutilized?(MDPI, 2023-08-14) Robinson, Tyler P.; Milgrom, Daniel P.; Nagaraju, Santosh; Goggins, William C.; Samy, Kannan P.; Koniaris, Leonidas G.; Surgery, School of MedicineSarcomas 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.
