The European Organization for Research and Treatment of Cancer 58881 study was designed to test in a prospective multicentric randomized trial the value of high-dose (HD) intravenous (IV) cytarabine (Ara-C) added to HD IV methotrexate (MTX) to reduce the incidence of CNS and systemic relapses in children with increased-risk acute lymphoblastic leukemia (ALL) or stage III and IV lymphoblastic lymphoma treated with a Berlin-Frankfurt-Munster (BFM)-based regimen.
 children with increased-risk acute lymphoblastic leukemia (ALL) or stage III and IV lymphoblastic lymphoma: Subject; children: Subject.Age; reduce the incidence of CNS and systemic relapses: Effect; high-dose (HD) intravenous (IV) cytarabine (Ara-C) added to HD IV methotrexate (MTX): Treatment; high-dose: Treatment.Dosage; intravenous: Treatment.Route; cytarabine: Treatment.Drug; methotrexate: Treatment.Drug; acute lymphoblastic leukemia: Treatment.Disorder; stage III and IV lymphoblastic lymphoma: Treatment.Disorder; cytarabine: Combination.Drug; methotrexate: Combination.Drug
Given event type and trigger, please tell me the arguments of all the listed option. Output format is "name1: role1; name2: role2". 
Event type: potential therapeutic event 
  Option: Treatment.Freq, Subject.Population, Combination.Drug, Subject.Gender, Treatment.Duration, Subject, Effect, Treatment, Treatment.Disorder, Treatment.Time_elapsed, Subject.Disorder, Subject.Race, Treatment.Route, Treatment.Dosage, Subject.Age, Treatment.Drug
