Malignant hemangiopericytoma in the pelvic cavity successfully treated by combined-modality therapy: report of a case.
A 55-year-old Japanese woman underwent extirpation of a malignant hemangiopericytoma in the pelvic cavity, followed by postoperative irradiation. An abdominal computed tomography scan 3 years later revealed a local recurrent tumor, 12 cm in diameter, in the pelvic cavity, for which transarterial embolization was done, followed by excision of the tumor employing Hartmann's procedure. Although an unresectable part of the recurrent tumor remained, postoperative irradiation reduced its size remarkably. The patient is still alive 7 years 2 months after her first operation, but with more recurrent tumors in the abdominal wall and around the bilateral iliac arteries. Because hemangiopericytoma often recurs or metastasizes after a prolonged disease-free interval, close long-term follow-up is necessary after the operation. Combined-modality therapy against the recurrent or unresectable disease may result in a good prognosis.
