Neurofibromatosis in children with rhabdomyosarcoma: A report from the intergroup Rhabdomyosarcoma Study IV

We identified all children enrolled in the Intergroup Rhabdomyosarcoma Study Group-IV with neurofibromatosis type I (NF1) and rhabdomyosarcoma. Among 1025 eligible patients, 5 (0.5%) had NF1. Three children had relapses, two of whom died of progressive disease. Patients with NF1 and rhabdomyosarcoma should be treated with intensive contemporary therapy protocols.
