title: Radiotherapy in the treatment of dermatofibrosarcoma protuberans.
abstract: OBJECTIVE
  To evaluate the role of postoperative radiotherapy (RT) for patients with dermatofibrosarcoma protuberans (DFSP).
  
  
  METHODS
  Ten patients were treated with surgery and postoperative RT and had follow-up from 21 to 185 months. Nine patients had DFSP and 1 patient had a fibrosarcomatous component (DFSP-FS). No patient had gross disease at the time of RT.
  
  
  RESULTS
  Nine patients with DFSP remained disease free after surgery and postoperative RT. The patient with DFSP-FS experienced a local recurrence after surgery, external beam RT, and a brachytherapy boost, and died with disease. There were no severe complications.
  
  
  CONCLUSIONS
  Postoperative RT may reduce the risk of local recurrence in patients with DFSP who have a high risk of residual disease after surgery.
