To further explore the expression of BLK and LCK in DSRCT, we used publicly available microarray data from 137 patients with fusion-positive sarcomas [33], including DSRCT (n = 28), alveolar rhabdomyosarcoma (ARMS; n = 23), alveolar soft part sarcoma (ASPS; n = 12), Ewing sarcoma (ES; n = 28), and synovial sarcoma (SS; n = 46). The gene discussed is LCK; the disease is synovial sarcoma.
