Elimination of Established Risk-Factors in Primary Central Nervous System Lymphoma - Impact of High-Dose Chemotherapy Followed by Autologous Stem-Cell Transplantaion - a Multicenter Retrospective Analysis

Abstract Abstract 3089 Introduction: High-dose chemotherapy (HDT) and autologous stem-cell transplantation (ASCT) demonstrated high efficacy in the treatment of newly-diagnosed primary CNS lymphoma (PCNSL) in eligible patients (pts). Prognosis of PCNSL is associated with several clinical and histopathological risk factors (RF). Early complete response (CR) during chemotherapy (CHT) was recently reported to be an additional independent prognostic factor in pts undergoing polychemotherapy without HDT+ASCT. In this analysis, we examined the extent to which known RF determined survival in pts who were treated with HDT-ASCT. We additionally investigated the impact of HDT-ASCT specific factors (e…
