Infused autograft lymphocyte to monocyte ratio and survival in T-cell lymphomas post-autologous peripheral blood hematopoietic stem cell transplantation.

Abstract

e19500 Background: We recently reported that the infused autograft lymphocyte to monocyte ratio (A-LMR) is a prognostic factor for survival in B-cell lymphomas post-autologous peripheral hematopoietic stem cell transplantation (APHSCT). Thus, we set out to investigate if the A-LMR is also a prognostic factor for survival post-APHSCT in T-cell lymphomas. Methods: From 1998 to 2014, 109 T-cell lymphoma patients that underwent APHSCT were studied. Receiver operating characteristic and area under the curve identified an A-LMR ≥ 1 as the best cut-off value and validated by the k-fold cross-validation. Results: . Multivariate analysis showed A-LMR to be an independent prognostic factor for overall survival (OS) and progression-free survival (PFS). Patients with an A-LMR ≥ 1.0 experienced a superior OS and PFS versus patients with an A-LMR < 1.0 [median OS was not reached vs 17.9 months, 5-year OS rates of 87% (95 CI, 75%-94%) vs 26% (95 CI, 13%-42 %), p < 0.0001, respectively; median PFS was not reached vs 11.9...
