Pediatric ovarian angiosarcoma treated with systemic chemotherapy and cytoreductive surgery with heated intraperitoneal chemotherapy: Case report and review of therapy.

Ovarian angiosarcoma is a rare and aggressive vascular tumor, which has a 5-year overall survival of less than 30% for patients with nonmetastatic disease and almost certain death within 1 year for those with metastasis. Here, we briefly review historical approaches to therapy and present a long-term survivor in the case of an 11-year-old female with metastatic ovarian angiosarcoma. This is the second reported case to utilize heated intraperitoneal chemotherapy in the treatment of this disease. Our patient is currently alive and well 3 years after initial diagnosis, significantly longer than any reported case of advanced-stage ovarian angiosarcoma.
