Abstract
AbstractChordomas originate from remnant tissue of the notochord during embryonic development, with a relatively low incidence rate. Furthermore, chordomas, being resistant to radiotherapy, are primarily treated by resection; however, in some cases, particularly in those that involve the skull base or upper cervical spine, chordomas are unresectable. In recent years, carbon ion/proton beam therapy has shown significant efficacy in such cases. However, it is not sufficiently curative and is commonly associated with recurrence. Moreover, there is no consensus regarding the treatment of recurrent cases, resulting in several uncertainties pertaining to it. Here, we present the case of a 55-year-old male patient with axial chordoma who experienced recurrence after carbon ion therapy and underwent tumor reduction surgery for a longer life span. Two months postoperatively, dehiscence was found in the posterior pharyngeal wall, probably due to heavy ion therapy. Salvage surgery was performed using an osteocutaneous radial forearm free flap, and the patient's postoperative course was uneventful.
