Abstract
The Center for International Blood and Marrow Transplant Research (CIBMTR) is a research collaboration between the National Marrow Donor Program (NMDP)/Be The Match and the Medical College of Wisconsin (MCW). The CIBMTR collaborates with the global scientific community to advance hematopoietic cell transplantation (HCT) and cellular therapy worldwide to increase survival and enrich quality of life for patients. The observation research program within CIBMTR is organized into 15 working committees. This review is aiming to highlight the observational research studies published by the CIBMTR Lymphoma Working committee over the last five years (2013-18) and to summarize how these studies have impacted the field by helping inform clinical practice in scenarios where prospective data from high quality randomized trials were not available or where owing to the rarity of a particular transplant indication such data were unlikely to be generated, outside the setting of a large observational research database. The salient findings reviewed include; (a) studies supporting role of autologous HCT in diffuse large B-cell lymphoma (DLBCL) patients with sensitive relapse of disease within one year of diagnosis, (b) role of autologous HCT vs allogeneic HCT in follicular lymphoma patients with early therapy failure, (c) prognostic scoring system development for classical Hodgkin lymphoma and DLBCL patients with prior autograft failure, (d) defining the role of alternative donor transplantation in lymphomas, (e) evaluating appropriate conditioning regimens for HCT in lymphoma, and (f) outcomes of HCT in rare lymphoid malignancies.
