The objective of the present study is to evaluate the activity and safety of imatinib in patients with aggressive fibromatosis who, after receiving the standard therapy, show an inoperable recurrent tumor or disease not readily controllable by surgery or radiotherapy.

Aggressive Fibromatosis
Desmoid Tumor
Drug: Imatinib
Phase 2

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase II Study to Evaluate Glivec (Imatinib Mesylate) to Induce Progression Arrest in Aggressive Fibromatosis / Desmoid Tumors Not Amenable to Surgical Resection With R0 Intent or Accompanied by Unacceptable Function Loss
