Central nervous system (CNS) relapse in acute myeloid leukemia (AML) is rare, but prognostically extremely unfavorable and associated with very high mortality rates. Aim of our single-center study was to define risk factors for CNS relapse in patients with FLT3-mutated AML after allogeneic hematopoietic cell transplantation (HCT) and to determine the impact of pre-emptive or salvage therapy with FLT3-inhibitors (FLT3i) on occurrence of CNS relapse and overall prognosis. We analyzed 39 FLT3-mutated AML patients who were treated with intensive induction therapy and consecutively underwent HCT at our institution.

Owing to the rapidly progressing field of CAR-T cell therapy and the lack of generally accepted treatment guidelines, we hypothesized significant differences between centers in the prevention, diagnosis, and management of short- and long-term complications.
Methods: To capture the current CAR-T cell management among German centers to determine the medical need and specific areas for future clinical research, the DAG-HSZT (Deutsche Arbeitsgemeinschaft für Hämatopoetische Stammzelltransplantation und Zelluläre Therapie; German Working Group for Hematopoietic Stem Cell Transplantation and Cellular Therapy) performed a survey among 26 German CAR-T cell centers.
Little is known about the cellular immune response to SARS-CoV-2 vaccination in patients after HSCT and B-NHL with iatrogenic B-cell aplasia. In nonseroconverted HSCT patients, induction of specific T-cell responses was assessed. The majority of allogeneic HSCT patients not showing humoral responses to vaccination also fail to mount antigen-specific T-cell responses.
