In patients who have central nervous system (CNS) involvement or who are at higher risk for CNS relapse, intrathecal chemotherapy is usually given in five doses. The regimen is a combination of cytarabine (50 mg), methotrexate (15 mg), and hydrocortisone (30 mg), given weekly for 5 weeks. For prophylaxis, one dose is given during induction, and four doses are given during consolidation. [42]
