Outcome of Aggressive Fibromatosis Treated with Radiation Therapy

Abstract

Introduction The purpose of this study is to report the clinical course and outcome in 7 patients with aggressive fibromatosis. Material and Methods Between the years 2000 and 2003, 7 patients who were treated with combined modalities were evaluated retrospectively. Patients' demographic information, including age and gender, tumour characteristics, surgical resection, and the use of radiotherapy were recorded and evaluated. Results The mean patient age was 34 years. The median time to follow-up was 15.5 months. Resection was performed with positive surgical margins in three cases. Three patients were evaluated as inoperable and one patient was treated with debulking surgery. All patients received radiation therapy with a median dose of 51 Gy. At followup, three patients had no evidence of disease, three patients were alive with disease, and one patient died 15 days after radiotherapy. Conclusion Local control is the primary problem in aggressive fibromatosis. There is no appropriate treatment for aggressive fibromatosis and the type of treatment depends on tumour characteristics and location as well as patient characteristics.
