Recurrent hemangiopericytoma and brachytherapy

Abstract

A 42-year-old woman had two recurrences following excision of a hemangiopericytoma of the left orbit. A third local excision was followed by postoperative brachytherapy (55 Gy in 100 hours). One year later there is no sign of recurrence and the side-effects are minimal.

Endovascular Preoperative Embolization of Orbital Hemangiopericytoma With n-Butyl Cyanoacrylate Glue

“…11,12 Other reports have described the use of preoperative radiation, 8 adjunctive proton beam therapy, 13 and adjunctive brachytherapy for primary and/or recurrent hemangiopericytomas. 14 As intraoperative hemorrhage can be a risk in these cases, 6,7 some reports have discussed the use of preoperative embolization. Methods for embolization have included polyvinyl alcohol, Onyx (eV3-Covidian, Irvine, CA), and particulate embospheres (150–300 μm).…”

New combined treatment of surgery, radiotherapy, and reconstruction in head and neck rhabdomyosarcoma in children: The amore protocol

“…Exenteration of the eye and severe facial mutilation could be avoided. Based on the promising results of 17 patients with orbital tumors, [28][29][30] a new method of combined surgery, brachytherapy, and reconstruction was developed for children with recurrent or residual RMS in the head and neck after chemotherapy, called the AMORE protocol. All selected patients had advanced disease, and without additional surgery and/or radiotherapy, survival was expected to be less than 3 months.…”

A case of orbital hemangiopericytoma in a dog

“…In both humans and the dog, wide surgical excision without rupture of the tumor’s capsule (if present) or with a clear margin free of neoplastic cells is obligatory if recurrence is to be avoided. Although HP is a radiation‐resistant tumor, several studies in the human 34–36 and veterinary 37 literature present the efficacy of high‐dose radiotherapy in cases of incomplete excision or local recurrences.…”
