Abstract
The American Society for Transplantation and Cellular Therapy (ASTCT) published its guidelines on indications for autologous and allogeneic hematopoietic cell transplantation (HCT) and immune effector cell therapy (IECT) in 2020. Since then we have witnessed rapid advancements in the field of IECT, resulting in several new chimeric antigen receptor T-cell (CAR-T) products and disease indications being approved by the U.S. Food and Drug Administration (FDA). To keep abreast of these practice changes, the ASTCT Committee on Practice Guidelines commissioned a focused update covering CAR-T therapy indications. This brief manuscript presents updated ASTCT recommendations on indications for CAR-T therapy. Only FDA approved indications for CAR-T were recommended and categorized as "standard of care" (S), where indication is well defined and supported by evidence. The ASTCT will continue to periodically review these guidelines and update them as new evidence becomes available.

Abstract
New options for medical therapy and risk scoring systems containing molecular data are leading to increased complexity in the management of patients with myelofibrosis. To inform patients' optimal care, we updated the 2015 guidelines on indications for and management of allogeneic haematopoietic stem-cell transplantation (HSCT) with the support of the European Society for Blood and Marrow Transplantation (EBMT) and European LeukemiaNet (ELN). New recommendations were produced using a consensus-building methodology after a comprehensive review of articles released from January, 2015 to December, 2022. Seven domains and 18 key questions were selected through a series of questionnaires using a Delphi process. Key recommendations in this update include: patients with primary myelofibrosis and an intermediate-2 or high-risk Dynamic International Prognostic Scoring System score, or a high-risk Mutation-Enhanced International Prognostic Score Systems (MIPSS70 or MIPSS70-plus) score, or a low-risk or intermediate-risk Myelofibrosis Transplant Scoring System score should be considered candidates for allogeneic HSCT. All patients who are candidates for allogeneic HSCT with splenomegaly greater than 5 cm below the left costal margin or splenomegaly-related symptoms should receive a spleen-directed treatment, ideally with a JAK-inhibitor; HLA-matched sibling donors remain the preferred donor source to date. Reduced intensity conditioning and myeloablative conditioning are both valid options for patients with myelofibrosis. Regular post-transplantation driver mutation monitoring is recommended to detect and treat early relapse with donor lymphocyte infusion. In a disease where evidence-based guidance is scarce, these recommendations might help clinicians and patients in shared decision making.

American Society for Transplantation and Cellular Therapy Guidelines for Fellowship Training in Hematopoietic Cell Transplantation and Immune Effector Cell Therapy
Jain, T., Knight, T., Alencar, M. C., Davis, L., Rao, K., Im, A., Malone, A. K., For The American Society For, Transplantation, Cellular Therapy Committee On, Education
Transplantation and cellular therapy. 2021
Abstract
The rapidly advancing field of hematopoietic cell transplantation (HCT) as well as the advent of immune effector cell therapy (IEC) has resulted in an increasing number of patients undergoing these therapies and a greater level of expertise required to manage them. Previous guidelines for the training of HCT physicians were last published in 2012. In recognition of the expanding knowledge base and increasing skill set essential to the delivery of these treatment modalities, the American Society for Transplantation and Cellular Therapy Committee on Education has updated these guidelines to reflect nearly a decade of new knowledge in the field of HCT, as well as the evolution of IEC from an experimental modality to a widely utilized and mainstream therapy. The resulting document reflects the Committee on Education's recommended educational structure for programs engaged in the training, evaluation, and mentorship of HCT/IEC trainees.

Hematopoietic Cell Transplantation in the Treatment of Newly Diagnosed Adult Acute Myeloid Leukemia: An Evidence-Based Review from the American Society of Transplantation and Cellular Therapy
Dholaria, B., Savani, B. N., Hamilton, B. K., Oran, B., Liu, H. D., Tallman, M. S., Ciurea, S. O., Holtzman, N. G., Ii, G. L. P., Devine, S. M., et al
Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation. 2020
Abstract
The role of hematopoietic cell transplantation (HCT) in the management of newly diagnosed adult acute myeloid leukemia (AML) is reviewed and critically evaluated in this evidence-based review. An AML expert panel, consistent of both transplant and non-transplant experts was invited to develop clinically relevant frequently asked questions covering disease- and HCT-related topics. A systematic literature review was conducted to generate core recommendations that were graded based on the quality and strength of underlying evidence based on the standardized criteria established by American Society of Transplantation and Cellular Therapy Steering Committee for evidence-based reviews. Allogeneic HCT offers a survival benefit in patients with intermediate and high-risk AML and is currently a part of standard clinical care. We recommend the preferential use of myeloablative conditioning in eligible patients. A haploidentical related donor marrow graft is preferred over a cord blood unit in the absence of a fully HLA-matched donor. The evolving role of allogeneic HCT in the context of measurable residual disease monitoring and recent therapeutic advances in AML with regards to maintenance therapy after HCT are also discussed.

Abstract
Axicabtagene ciloleucel (YESCARTA(R), Kite Pharma, a Gilead Company) and tisagenlecleucel (KYMRIAH(R), Novartis Pharmaceuticals Corp.) are two CD19-directed chimeric antigen receptor T cell (CD19 CAR T) products that are currently approved by the U.S. Food and Drug Administration, the European Medicines Agency, Health Canada, Ministry of Health, Labor and Welfare (Japan) and Therapeutic Goods Administration (Australia) for treatment of specific subtypes of relapsed/ refractory aggressive B cell non-Hodgkin lymphoma (NHL). While this approval has been transformative in the use of cellular immunotherapy in lymphoma, there are concerns regarding appropriate utilization of this novel therapy, as well as short- and long-term toxicities. To address these issues, representatives of American Society of Transplantation and Cellular Therapy (ASTCT) convened to recognize and address key issues surrounding the clinical application of CD19 CAR T cell therapy in B cell lymphomas, in collaboration with worldwide experts and members of International Society of Cell and Gene Therapy (ISCT), American Society of Hematology (ASH), Foundation for the Accreditation of Cellular Therapy (FACT) and European Society for Blood and Marrow Transplantation (EBMT). The aim of this article is to provide consensus opinion from experts in the fields of hematopoietic cell transplantation, cellular immunotherapy, and lymphoma regarding key clinical questions pertinent to the utilization of CD19 CAR T for the treatment of NHL. As the clinical practice using CAR T cells grows worldwide, we anticipate that this guidance will be relevant for hematology/oncology physicians who care for patients with lymphomas.
