Tenosynovial giant cell tumor is a rare proliferative tumor that arises from the synovium, bursae, or tendon sheaths due to an overproduction of colony-stimulating factor 1. Historically, treatment options for patients with local or diffuse tenosynovial giant cell tumor have been limited to surgical interventions. However, for some patients, surgical resection could worsen functional limitations and/or morbidity. In August 2019, the FDA approved pexidartinib (TURALIO™, Daiichi Sankyo), the first systemic treatment option for adult patients with symptomatic tenosynovial giant cell tumor associated with severe morbidity or functional limitations that were not amenable to improvement with surgery. Pexidartinib is an oral tyrosine kinase inhibitor with selective inhibition of colony-stimulating factor 1 receptor and is the first systemic therapy to show significant improvement in overall response rates when compared with placebo. Clinicians using pexidartinib should monitor for liver-related adverse events, which may require treatment interruption, dose reduction, or treatment discontinuation. Pexidartinib provides a novel non-surgical treatment option for patients with tenosynovial giant cell tumor that may significantly improve patients’ overall response, range of motion, physical function, tumor volume, and stiffness.
