Further study details as provided by European Organisation for Research and Treatment of Cancer - EORTC:

Primary Outcome Measures:
  • Local control as assessed by MRI at 3 years

Secondary Outcome Measures:
  • Toxicity as assessed by CTC 2.0
  • Response as assessed by MRI

Enrollment: 44
Study Start Date: November 2001
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine the efficacy of moderate-dose radiotherapy, in terms of local control, in patients with aggressive fibromatoses.
  • Determine the acute and late side-effects of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive radiotherapy 5 days a week for 5.5 weeks for a total of 56 Gy in 28 fractions.

Patients are followed every 3 months for 2 years and then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study within 3 years.


Ages Eligible for Study:   16 Years and older   (Child, Adult, Senior)
