[A Case of Recurrent Ovarian Fibrosarcoma Resected by Pancreaticoduodenectomy]

A 66-year-old woman presented to the Department of Gynecology in our institution in 2005 with peritoneal recurrence of ovarian fibrosarcoma. Originally, combined modality therapy including repeated surgical resection and somatic chemotherapy was performed. A peritoneal recurrence was found near the pancreatic head. She was referred to our department in October 2015, and underwent pancreaticoduodenectomy. The tumor was severely adhesive to the portal vein and combined portal venous resection was performed. Histological examination of tumor specimens revealed tumor invasion to the adjacent pancreatic parenchyma and portal vein. No evidence of recurrence was detected after a follow-up of 8 months. We suggest that in cases with peritoneal recurrence of ovarian tumors, radical resection might be considered, taking into account the biologic behavior of the tumor.
