Background: Aggressive non-Hodgkin lymphomas with secondary central nervous system (CNS) involvement bear a dismal prognosis. Optimal treatment remains so far unclear, and effective treatment options remain an unmet clinical need. Remission rates are in general low, resulting in rapid relapses and palliative care in the majority of patients. High-intensity treatment combining effective CNS-directed chemoimmunotherapy with autologous stem cell transplantation was shown in a recent phase 2 trial to induce durable remissions. Here, we report the outcome of the first real-world patient cohort treated according to the published protocol. Methods: We retrospectively identified 17 HIV-negative lymphoma patients with secondary CNS involvement, either at first diagnosis or at relapse of lymphoma, treated according to the study protocol published by Ferreri et al. [J Clin Oncol. 2015] at two university medical centers in Germany. Treatment consisted of four cycles of chemoimmunotherapy with a consolidating autologous stem cell transplantation. Adverse events and overall outcome were assessed. Results: Five patients had CNS involvement at first diagnosis and 12 patients at relapse of lymphoma. A complete response was achieved in 9 patients. Median survival was 11 months. Five patients died of septic complications and 4 patients succumbed to progression or relapse of disease. Conclusions: The outcome of our real-world cohort emphasizes the possible toxic character of the treatment protocol by Ferreri et al. [J Clin Oncol. 2015]. Further improvement in treatment regimens is still an unmet need.
