title: [Improving local control in patients with aggressive fibromatosis by combined surgery and radiotherapy].
abstract: BACKGROUND
  The purpose of this retrospective analysis is to evaluate whether the combination of surgery and radiation therapy in patients with aggressive fibromatosis influences the therapeutic outcome.
  
  
  METHODS
  Clinical, radiological and pathological results of 23 consecutive cases with histologically proven aggressive fibromatosis were retrospectively analyzed. The median follow-up was 59 months.
  
  
  RESULTS
  Twelve patients received surgery alone for their first treatment, 10 patients had a combination of surgery and radiotherapy and 1 patient had radiochemotherapy. Of 23 patients 14 (63%) had one or more local recurrences and 9 (39%) were recurrence-free. The patients received a total of 50 treatments: 29/50 (58%) treatments were followed by a local recurrence and 21/50 (42%) were without relapse. Twenty-nine treatments with local recurrence consisted of 25/29 (86%) surgical treatments, 3/29 (10%) combinations of surgery and radiation therapy, and 1/29 (3%) radiochemotherapy. Of the patients who had only surgery for their first treatment, after one year 8 of 12 (66%) and after 5 years all patients had a local recurrence. In the group with surgery and radiotherapy, there was no recurrence after 1 year and 1 recurrence after 5 years (p = 0.0001).
  
  
  CONCLUSIONS
  We recommend a complete tumor resection, without mutilating the patient. Radiation therapy in combination with surgery in contrast to surgery alone is an efficient treatment option for reducing local recurrence.
