Five years of local control of subscapularis aggressive fibromatosis managed by surgery and imatinib: a case report.

Abstract

INTRODUCTION:

Imatinib, a tyrosine kinase inhibitor, is a major therapeutic option for the management of unresectable aggressive fibromatosis. Unfortunately, for most patients of low or very low average income countries, surgery often is the first treatment option. This is related to unavailability of chemotherapy or targeted therapy, and to a lack of financial resources or surgeons' lack of knowledge of other therapeutic options.

CASE PRESENTATION:

In 2010, a 26-year-old Moroccan man was referred to our oncology and radiotherapy center by his surgeon for the management of a recurrent tumor of his right subscapularis muscle. Before his assessment in our center, two resections were performed by his surgeon after performing an incision biopsy and magnetic resonance imaging. Postoperative magnetic resonance imaging was performed and showed a right axillary nodule size 2.1cm regarding a collection with a residual tumor. We decided to administer imatinib 400mg daily by mouth. Clinical and magnetic resonance imaging evaluation were performed regularly and reported a stable tumor. We reported no adverse side effects to imatinib regarding Common Terminology Criteria for Adverse Events grading.

CONCLUSIONS:

Recurrences are high during aggressive fibromatosis management. Systemic treatment with imatinib for unresectable or recurrent tumors with positive c-KIT could be the best therapeutic option. In our case report, the patient was stabilized with imatinib for 30 months and he had a very good quality of life.
