A prophylactic tyrosine kinase inhibitor strategy based on measurable residual disease pre-transplantation for Ph acute lymphoblastic leukemia undergoing allogeneic hematopoietic stem cell transplantation: A prospective multicenter cohort study.

Relapse is the major cause of treatment failure in Philadelphia chromosome-positive (Ph) acute lymphoblastic leukemia (ALL) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study aimed to evaluate the effect of a prophylactic tyrosine kinase inhibitor (TKI) strategy on relapse in this population. Patients were assigned to prophylactic or control groups based on measurable residual disease (MRD) pre-transplantation.

Adoptive therapy with cytomegalovirus-specific cytotoxic T lymphocytes for refractory cytomegalovirus DNAemia and disease after allogeneic haematopoietic stem cell transplantation.

Cytomegalovirus (CMV) DNAemia and disease are common complications in patients undergoing allogeneic haematopoietic stem cell transplantation (allo-HSCT). Few studies have compared the efficacy and safety of the HSCT donor and third-party CMV-specific cytotoxic T lymphocytes (CMV-CTLs) in the treatment of CMV DNAemia and disease. In this study, we retrospectively compared the efficacy and safety of HSCT donor and third-party CMV-CTLs in patients with refractory CMV DNAemia or disease after allo-HSCT at our centre from January 2017 to September 2021.

Sorafenib maintenance after allogeneic haemopoietic stem-cell transplantation in patients with FLT3-ITD acute myeloid leukaemia: long-term follow-up of an open-label, multicentre, randomised, phase 3 trial.

Background: Our open-label, multicentre, randomised, phase 3 trial showed that sorafenib maintenance after haematopoietic stem-cell transplantation (HSCT) improved overall survival and reduced relapse for patients with FLT3 internal tandem duplication (FLT3-ITD) acute myeloid leukaemia undergoing allogeneic HSCT. Here, we present a post-hoc analysis on the 5-year follow-up data of this trial.

Methods: This phase 3 trial, done in seven hospitals in China, included patients with FLT3-ITD acute myeloid leukaemia undergoing allogeneic HSCT, who were aged 18-60 years, had an Eastern Cooperative Oncology Group performance status of 0-2, had composite complete remission before and after transplantation, and had haematopoietic recovery within 60 days after transplantation.
