Intraoperative electron radiation therapy in retroperitoneal sarcoma

We conducted a retrospective evaluation of 156 patients (56% recurrent status) with retroperitoneal sarcomas treated by surgery, IORT +/- EBRT. The combination approach was feasible and resulted in good LC and OS in this unfavourable cohort. Incomplete resection and recurrent status resulted in clearly inferior outcome. Reasonable efforts should be made already during primary treatment to prevent the onset of a local recurrence.
