In this retrospective study of patients with central nervous system lymphoma, consolidation with autologous stem cell transplantation in the first-line and relapse setting appears to be safe and has potential to reduce risk of relapse in patients with chemotherapy-sensitive disease. Background: Central nervous system (CNS) lymphoma is associated with poor outcomes. Autologous stem cell transplantation (ASCT) has been reported to improve outcomes when used as a consolidation strategy in primary CNS lymphoma (PCNSL) and as a salvage strategy in patients with disease relapse limited to the CNS. Herein, we describe our experience of using ASCT in PCNSL and secondary CNS lymphoma (SCNSL). Patients and Methods: We evaluated clinical outcomes of 18 patients from 2 major academic centers with a median age of 55 (range, 46-72) years. Thirteen patients had PCNSL and 5 patients had SCNSL. Most of the cases were in the first (CR1) or second (CR2) complete remission (CR1 = 7, CR2 = 7) at the time of ASCT. Carmustine with thiotepa (n = 12, 67%) was the most commonly prescribed preparative regimen. Results: The median follow-up from ASCT for surviving patients was 12 (range, 0.9-115) months. The 2-year progression-free survival (PFS) and overall survival (OS) were 74% (95% confidence interval [CI], 48%-99%) and 80% (95% CI, 55%-100%), respectively. Two-year non-relapse mortality was 0%. The 2-year cumulative incidence of relapse/progression was 27% (95% CI, 10%-72%). In subgroup analysis of PCNSL patients, 2-year PFS, OS, and relapse were 71% (95% CI, 38%-100%), 71% (95% CI, 38%-100%), and 29% (95% CI, 9%-92%), respectively. Conclusion: In this retrospective study of patients with CNS lymphoma, consolidation with ASCT after high-dose methotrexate-based chemotherapy is safe and effective in reducing disease relapse.
