Multiple EWSR1-WT1 and WT1-EWSR1 copies in two cases of desmoplastic round cell tumor..     ///    Our study demonstrated that an integrated molecular cytogenetic approach identified EWSR1-WT1 cooperating molecular events and genetic markers for prognosis.     ///    "Common genomic events (i.e., trisomy 3 and extra EWSR1-WT1 and WT1-EWSR1 copies) probably contributed to disease pathogenesis and/or evolution of DSRCT.
