Successful Re-resection for Locally Recurrent Retroperitoneal Liposarcoma at Four Years After Ex Vivo Tumor Resection and Autotransplantation of the Liver: A Case Report.

Abstract：

:Surgical resection should be considered for isolated locally recurrent retroperitoneal liposarcomas. We experienced a case of successful re-resection for locally recurrent retroperitoneal liposarcomas 4 years after ex vivo tumor resection and autotransplantation of the liver. A 75-year-old man was admitted to our hospital. His diagnosis was local recurrence of liposarcomas. He had previously undergone ex vivo tumor resection and autologous orthotopic liver transplantation for a retroperitoneal tumor 4 years earlier. The resected tumor size was 23.5 × 15.5 × 12.5 cm. The tumor was revealed by means of histopathologic study to be a myxoid liposarcoma. Follow-up computerized tomography showed 2 recurrent tumors in the retropancreatic and para-aortic lesions. Although adhesion was severe within the operative field, we successfully performed complete en bloc re-resection of each recurrent tumor. The operative time was 250 minutes, and blood loss was 300 mL. The resected tumor sizes were 3.9 × 3.2 × 1.5 cm and 4.5 × 3.3 × 3.0 cm. The tumors were revealed by means of histopathologic study to be dedifferentiated liposarcomas. Postoperative complications included intestinal obstruction and colocutaneous fistula formation, both of which were treated surgically. The patient was discharged in an ambulatory state at 80 days after re-resection of the recurrent tumors. At the time of writing, he was alive with no evidence of recurrence, 14 months after re-resection and 62 months after primary ex vivo tumor resection. This is the first case of successful surgical re-resection for locally recurrent liposarcoma after ex vivo tumor resection and autotransplantation of the liver.
