Treatment

Surgical Therapy

Because even benign-appearing solitary fibrous tumors (SFTs) can be locally recurrent and metastatic, wide resection is recommended for both benign and malignant SFTs. Preoperative vascular studies and arterial embolization should be considered because of the known bleeding risk with resection. [5, 15] Careful exclusion of other diagnoses (eg, synovial sarcoma) is important. Because of the favorable outcome with SFTs, it may be possible to avoid limb-threatening and deforming operations. [6]

No evidence suggests that adjuvant chemotherapy is beneficial. If the SFT appears malignant histologically, adjuvant radiation therapy may be considered. Long-term follow-up is recommended because local and distant relapse is possible, even with benign-appearing tumors.
