Abstract

PURPOSE:

To evaluate local control rates in patients treated with radiotherapy for aggressive fibromatosis.

METHODS AND MATERIALS:

Fifty-three patients with histologically confirmed aggressive fibromatosis were treated with radiotherapy at the University of Florida between march 1975 and June 1992. The minimum length of follow-up was 2 years; 81% of the patients had follow-up for at least 5 years. The lesions arose in an extremity or limb girdle (39 patients), the trunk (10 patients), or the head and neck area (4 patients). Twenty-four patients were treated for gross disease and 29 for presumed microscopic residual disease after one or more operations. Patients were treated with total doses between 35 and 70 Gy; 83% of patients received 50 to 60 Gy.

RESULTS:

Local control was achieved in 23 of 29 patients (79%) treated postoperatively for microscopic residual disease and in 21 of 24 patients (88%) treated for gross disease; gross disease was controlled in all 8 patients with previously untreated lesions and in 13 of 16 patients treated postoperatively for gross residual or recurrent disease. Overall, aggressive fibromatosis was locally controlled in 83% of treated patients. All nine treatment failures occurred in patients with extremity lesions 4 to 68 months after initiation of treatment. Three recurrences were in the irradiated field, two were out of the field, and four were at the field margin. Eight patients were salvaged with surgery alone or combined with postoperative radiotherapy. A functional limb was maintained in 38 of 39 patients with extremity or limb girdle lesions. Pathologic fracture occurred in three patients; two patients required rod fixation for treatment.

CONCLUSIONS:

Radiotherapy is a valuable adjunct to surgery in the management of aggressive fibromatosis and can be used alone in patients with unresectable or inoperable disease.
