[Humanized anti-CD25 monoclonal antibody as a salvage therapy for steroid-refractory acute graft-versus-host disease after hematopoietic stem cell transplantation].

To investigate the efficacy of humanized anti-CD25 monoclonal antibody for steroid-refractory acute graft-versus-host disease (SR-aGVHD) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. A total of 64 patients with SR-aGVHD between June 2019 and October 2020 in Suchow Hopes Hematology Hospital were enrolled in this study. Humanized anti-CD25 monoclonal antibodies 1 mg·kg(-1)·d(-1) were administered on days 1, 3, and 8, and then once per week according to the disease progression.

[Analysis of the efficacy and safety of plerixafor combined with G-CSF in plasma cell disease mobilization].

To analyze the effect and safety of plerixafor combined with G-CSF mobilization in plasma cell disease. The clinical baseline data, success rate of collection, and adverse reactions of consecutive cases of plasma cell disease were analyzed retrospectively, where the patients received plerixafor combined with G-CSF for autologous hematopoietic stem cell mobilization in Peking University People's Hospital from January 2018 to December 2019. Forty-nine patients with plasma disease were included, of which 39 (79.

Both the subtypes of KIT mutation and minimal residual disease are associated with prognosis in core binding factor acute myeloid leukemia: a retrospective clinical cohort study in single center.

Core binding factor acute myeloid leukemia (CBF-AML), including cases with KIT mutation, is currently defined as a low-risk AML. However, some patients have poor response to treatment, and the prognostic significance of KIT mutation is still controversial. This study aimed to explore the prognostic significance of different KIT mutation subtypes and minimal residual disease (MRD) in CBF-AML.

[Analysis of early death factors and prognosis of acute promyelocytic leukemia].

To summarize the clinical characteristics of an early death in patients with de novo acute promyelocytic leukemia (APL) , analyze the risk factors and direct causes of early death, and perform survival analysis. The clinical data of 368 patients with de novo APL in three centers (First Affiliated Hospital of Soochow University, Soochow Guangci Hospital, and Soochow Hopes Hospital of Hematology) during January 2011-December 2017 were retrospectively analyzed. The clinical characteristics of patients who suffered hemorrhagic early death and non-hemorrhagic early death were compared.

The loss or absence of minimal residual disease of <0·1% at any time after two cycles of consolidation chemotherapy in CBFB-MYH11-positive acute myeloid leukaemia indicates poor prognosis.

No consensus has been reached on the relationship between CBFB-MYH11 copies and prognosis. Of 1525 acute myeloid leukemia (AML) patients, 58 with CBFB-MYH11-positive AML (16/58 patients with c-kit mutation) were retrospectively analyzed with a median follow-up duration of 29.8 (range: 4.
