Abstract:The incidence of local recurrence after wide local excision and radiation of soft tissue sarcoma (STS) ranges from 5% to 20%.The optimal management of locally recurrent STS must be individualized. Approaches for retreatment include wide local re-excision followed by a variety of radiation which include external-beam radiation, brachytherapy and intraoperative electron radiotherapy. Following retreatment, the likelihood of ultimate local control ranges from 37% to 100%. However, each radiation technique could produce severe side effects, and so for selected patients, repeat irradiation may be unnecessary.
