A valuable diagnostic aid and important prognostic parameter in alveolar rhabdomyosarcoma is the identification of PAX3-FOXO1 [t(2;13)(q35;q14)] or PAX7-FOXO1 [t(1;13)(p36;q14)] rearrangements.     ///    Both PAX3- and PAX7-FOXO1 alveolar rhabdomyosarcomas were identified in these patients.    ///    "In children, PAX7-FOXO1 alveolar rhabdomyosarcoma is associated with a significantly longer event-free survival.
