Key clinical point: High-dose cytarabine (HDAC)-based pre-autologous stem cell transplantation (ASCT) induction regimens were not associated with improved survival but led to higher overall response rates (ORR) and lower rates of early relapses in ASCT-eligible patients with mantle cell lymphoma (MCL).
Major finding: Patients receiving rituximab + HDAC (R-HDAC)-based regimens vs rituximab + cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) had significantly higher ORR (85.9% vs 65.7%; P = .007), lower 24-month progression rates (61.9% vs 80.4%; P = .043), and lower mortality (43.9% vs 68.6%; P = .004). However, the 2-year overall survival rates were similar between the R-HADC + ASCT and R-CHOP + ASCT groups (88.7% and 78.8%, respectively; P = .289).
Study details: This retrospective single-center study included 165 ASCT-eligible adult patients with MCL, of whom 136 patients received pre-ASCT induction immunochemotherapy with R-CHOP-like or regimens based on R-HDAC and 50 patients received consolidation with high-dose therapy and ASCT.
Disclosures: This study did not receive any specific funding. The authors declared no conflicts of interest.
