Regimen, Rubenstein, et al. 2013 (CALGB 50202)
Level of Evidence: Phase II
Induction phase
- Methotrexate (MTX) 8000 mg/m2 IV once over 4 hours on day 1
- Given for a total of 7 doses.
- Folinic acid (Leucovorin) 100 mg/m2 IV every 6 hours, start on day 2, continue until MTX level <0.05
- Rituximab (Rituxan) 375 mg/m2 IV once on day 3
- Rituximab omitted for T-cell PCNSL and given for a total of 6 doses in all others.
- Temozolomide (Temodar) 150 mg/m2 PO once per day on days 7 to 11 (odd cycles only)
14-day cycles x 8 cycles
Patients achieving CR or CRu were given one additional cycle of methotrexate & temozolomide, followed by consolidation therapy:
Consolidation
- Etoposide (Vepesid) 40 mg/kg IV continuous infusion over 96 hours, days 1 to 4
- Cytarabine (Cytosar) 2 gm/m2 IV Q12H over 2 hours × 8 doses, days 1 to 4
One course

Relapsed/refractory
High-dose Methotrexate (MTX) & Ifosfamide
Regimen
Level of Evidence: Retrospective
- Methotrexate (MTX) 4000 mg/m2 IV over 4 hours once on day 1
- Ifosfamide (Ifex) 1500-2000 mg/m2 IV over 3 hours once daily on days 3 to 5
- Mesna (Mesnex) for prophylaxis of hemorrhagic cystitis
- Folinic acid (Leucovorin) rescue starting 24 hours after start of methotrexate infusion
- Sodium bicarbonate via IV fluid or PO routes used for urine alkalinization to maintain urine pH of at least 8
- Check methotrexate levels 24, 48, and 72 hours after completion of methotrexate infusion.
Methotrexate (MTX) dose adjusted for creatinine clearances <100 mL/min according to the following formula:
- Dose of methotrexate = (creatinine clearance/100) x 4000 mg/m2; the paper did not specify what method was used for calculating creatinine clearance. Patients with creatinine clearance <50 mL/min were excluded from the study.
up to 8 cycles (reference did not list timing/criteria to be used for next cycle of therapy)
