    Abstract: 7544 Background: Great heterogeneity in survival exists for patients (pts) newly diagnosed with aggressive BCL. Three scoring systems based on simple clinical parameters (age, lactate dehydrogenase, number/sites of involvement, stage, performance status) are widely used: the international prognostic index (IPI), revised-IPI (R-IPI), and National Comprehensive Cancer Network IPI (NCCN-IPI). We studied BCL pts treated with R-CHOP to determine which scoring systems best identifies subgroups with poor outcomes that might benefit from new approaches. Methods: Individual pt data from 7 multicenter trials (1998-2009) of pts with BCL (86% DLBCL) treated front-line with R-CHOP (or variant) were analyzed to determine whether IPI, R-IPI, or NCCN-IPI best discriminated overall survival (OS). The concordance index (c-index) from a proportional hazards model, stratifying on trial and induction therapy, quantified predictive accuracy of each scoring system. Results: 2561 pts (median age 63 yrs, 56% male) were classified into IPI, R-IPI, and NCCN-IPI risk groups (Table). With a median follow-up of 5 yrs, NCCN-IPI had the greatest absolute difference in OS estimates between the highest and lowest risk groups at 1, 3, and 5 yrs, and best discriminated OS (c-index = 0.631, Table). Conclusions: In an independent and large cohort of pts, NCCN-IPI performs best in risk-stratifying pts with aggressive BCL, readily distinguishing pts at high and low risk for treatment failure using clinical parameters (5-yr OS between 48 and 92%). Improvement over the simpler IPI appears incremental, and IPI may remain a valuable alternative. Work integrating molecular features of the tumor into the (NCCN-) IPI is in progress to define high risk groups where targeted novel approaches are needed most. [Table: see text]

    First-line therapy of T-cell lymphoma: Allogeneic or autologous transplantation for consolidation—Final results of the AATT study.
    American Society of Clinical Oncology (ASCO) ; 2019

    Abstract: 7503 Background: In patients (pts) with peripheral T-cell lymphoma (PTCL) results of first-line therapy remain poor; guidelines recommend consolidation with autologous transplantation (autoSCT) in transplant-eligible pts. AATT (Autologous or Allogeneic Transplantation in T-cell lymphoma) sought to improve first-line therapy and compared alloSCT with autoSCT. Methods: This was a prospective randomized trial comparing autoSCT with alloSCT in younger pts (18-60 yrs) with newly diagnosed PTCL who had achieved CR, PR, or SD after 4 courses of CHOEP and 1 course of DHAP. Pts were to receive BEAM followed by autoSCT or myeloablative conditioning (fludarabine, busulfan, cyclophosphamide) followed by alloSCT from a matched related or unrelated donor. Primary endpoint was 3-year event-free survival (EFS). The study was stopped prematurely after a pre-planned interim analysis (JCO 33, 2015, suppl 8507a). Results: 103 pts randomized upfront to autoSCT (n=54) or alloSCT (n=49) formed the full analysis set. Median age was 50 years, 63% were male. 36 pts (35%) could not proceed to transplantation mostly due to early progression. Median observation time for EFS was 42 months. 3-year EFS and overall survival (OS) did not significantly differ between alloSCT and autoSCT (EFS: 43% (95% CI29-57%) vs. 38% (25-52%), p=0.58, OS: 57% (43-71%) vs. 70% (57-82%) (p=0.41). Comparing pts who actually received autoSCT (n=41) or alloSCT (n=26) EFS, PFS, and OS also showed no significant difference. No patient relapsed but eight pts (31%) died of treatment-related mortality (TRM) after alloSCT compared to 13 relapses (36%) but no TRM observed after autoSCT. Comparison of pts with aaIPI 2/3 vs. 0/1 showed significant differences for all endpoints. Conclusions: AlloSCT or autoSCT given to consolidate response in pts with PTCL showed no significant survival differences. While exerting a strong GvL-effect alloSCT resulted in substantial TRM. For younger pts with PTCL autoSCT remains the preferred consolidation, in particular, because pts. relapsing after autoSCT can be successfully salvaged with alloSCT.
