Abstract
Introduction: Aggressive fibromatosis is a benign but locally aggressive process. It arises from musculo-aponeurotic tissues, and invades locally without respect for tissue planes, surrounding vessels and nerves, which makes treatment of local recurrences difficult.
Aims: Our aim is to review our experience in the management of aggressive fibromatosis, focussing on the cases of multiple recurrences, as well as to evaluate the need for disabling surgery.
Material and methods: We present the series of 33 patients (15 male and 18 female) diagnosed of aggressive fibromatosis treated between 1993 and 2003; the follow-up period was no less than two years. The locations were shoulder girdle (8), lower extremity (8), upper extremity (6), gluteus (5), paravertebral (4) and thorax (2). There were 6 cases with 3 or more episodes of local recurrences; in these cases, depending on location and size, and considering high surgical morbidity, associations of radiotherapy, chemotherapy and hormone therapy were given, avoiding disabling surgery.
Results: With an average follow-up of 32 months (25 to 50), there were no deaths and, in the 6 cases of multiple recurrences, there were no amputations. The control MRI demonstrated stability of the process in 5 out of 6 cases, and minimum growth without clinical correlation in the other one. In the other 27 cases, there were 14.8% surgical treated local recurrences, with no need for amputation.
Conclusion: We consider that cases of multiple recurrences of aggressive fibromatosis benefit from adjuvant treatment (radiotherapy, chemotherapy and hormone therapy), avoiding disabling surgery, which is unnecessary following our criteria. This requires strict clinical and radiological control.
