Added text to state that a phase II feasibility study used chemotherapy induction with methotrexate, temozolomide, and rituximab plus consolidation with etoposide and high-dose cytarabine; with a median follow-up of 4.9 years, this phase II Cancer and Leukemia Group B (CALGB) trial of 44 patients reported a complete radiographic response in 66% of the patients, a 2-year progression-free survival of 57%, and an estimated overall survival of 65% at 4 years (cited Rubenstein et al. as reference 34 and level of evidence 3iiiDiv). Also added that a randomized, prospective trial by the CALGB will compare this nonstandard induction regimen versus the same induction chemotherapy with myeloablative peripheral stem cell transplantation.
