BACKGROUND AND OBJECTIVES: When surgery is not adequate or feasible, stereotactic body radiotherapy (SBRT) reirradiation has been used for recurrent @entity5 . We report the outcomes of a series of @entity1 with pelvic recurrences from @entity14 reirradiated with SBRT. METHODS: The Cyberknife(TM) Robotic Stereotactic Radiosurgery system with fiducial based real time tracking was used. @entity1 were followed with imaging of the pelvis. RESULTS: Four @entity1 and 14 @entity1 with 22 lesions were included. The mean dose was 25   Gy in median of five fractions. The mean prescription isodose was 77%, with a median maximum dose of 32.87   Gy. There were two local failures, with a crude local control rate of 89%. The median overall survival was 43 months. One @entity1 had @entity29 and required surgery (Grade IV), two @entity1 had symptomatic @entity16 (1 Grade III) and one @entity1 developed @entity3041 from ureteric @entity82 requiring a stent (Grade III). CONCLUSIONS: Local recurrence in the pelvis after modern combined modality treatment for @entity14 is rare. However it presents a therapeutic dilemma when it occurs; often symptomatic and eventually life threatening. SBRT can be a useful non-surgical modality to control pelvic recurrences after prior radiation for @entity14 . J. Surg. Oncol.    2015 Wiley Periodicals, Inc.
