RET fusions were identified in three patients in the STS cohort – sarcoma NOS (n=2) and undifferentiated pleomorphic sarcoma (n=1) –, one patient in the bone sarcoma cohort (osteosarcoma), and one patient in the uterine sarcoma cohort (leiomyosarcoma). This evidence concerns the gene RET and undifferentiated pleomorphic sarcoma.
