Abstract

8021 Background: Transformation of untreated indolent B-cell lymphoma (Tr-iNHL) is associated with poor outcomes. Current practices are extrapolated from prospective studies of de novo large B-cell lymphoma (DLBCL) or small retrospective studies. High dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) is used as consolidation in first remission (CR1) in some centers but the evidence-base is weak. Methods: CLL/SLL, MCL as primary diseases and non-DLBCL transformations were excluded. Propensity score analysis (PSM) using the “greedy match” algorithm was used to match the baseline covariates to adjust for potential selection bias. Landmark analysis was performed with time ..
