title: The radiotherapeutic management of chordoid sarcoma.
abstract: Chordoid sarcoma is a rare neoplasm, with only 13 cases reported. In the past, the treatment of choice was excision or amputation, with radiation therapy reserved for metastases. This case report demonstrates the persistent nature and indolent course the tumor may have and its good response to high-dose irradiation. External beam irradiation, both photons and electrons, intraoperative radiation therapy, and 192-iridium implantation have all been successfully utilized for treatment of multiple recurrences in this patient. Doses of 6,000 cGy or greater were necessary to control the tumor in our patient, and this dose is recommended as adjuvant treatment following conservative (gross) tumor removal.
