Role of brachytherapy in the management of desmoid tumors.

ABSTRACT

From 1977 to 1982, fourteen patients with desmoid tumors underwent surgery and brachytherapy. Surgery ranged from biopsy to complete or partial excision of the tumor. Most of these patients had locally advanced tumor or positive margins. A high recurrence rate is expected in such a group if treated by surgery alone. In twelve out of fourteen patients the treatment was considered curative when all disease sites could be encompassed. In the remaining two patients the treatment was considered palliative because the tumor encroaching on to the spinal cord was left untreated. Ten out of twelve curatively treated patients have remained free of recurrence at a minimum of 2 year follow-up. Five of them were followed from 4-6 years. In the palliatively treated group, one patient is alive with active disease at 18 months. Three patients developed complications with wound healing. This experience suggests that surgery and brachytherapy treatment for desmoid tumor results in higher local control than expected from surgery alone in this selected group of patients.
