In the STS cohort, BRAF V600E mutations were identified in patients diagnosed with sarcoma NOS (n=4), angiosarcoma (n=2), solitary fibrous tumor (n=1), desmoid fibromatosis (n=1), round cell sarcoma NOS (n=1), embryonal rhabdomyosarcoma (n=1), and undifferentiated pleomorphic sarcoma (n=1). This evidence concerns the gene BRAF and solitary fibrous tumor.
