Desmoid-Type Fibromatosis: Evolving Treatment Standards.

Desmoid-type fibromatosis is a rare nonmetastasizing neoplasm with variable behavior. Recent discoveries into the biology of this disease hold promise for identifying prognostic and predictive features and novel therapeutic targets. Surgery has been the historical standard of care but carries considerable drawbacks in terms of high local recurrence rates and poor functional outcomes. Improved understanding of the natural history of desmoid-type fibromatosis has resulted in a paradigm shift toward nonoperative management. Effective medical treatment options include nonsteroidal antiinflammatory drugs, hormone therapy, cytotoxic chemotherapy, and targeted agents. A treatment algorithm has been proposed with the objective of optimizing treatment.
