Hematopoietic stem cell transplantation (HSCT) can cure malignant and nonmalignant hematological disorders. From 1983 to 2022, Taiwan performed more than 10,000 HSCT transplants. The Taiwan Blood and Marrow Transplantation Registry collects clinical information to gather everyone's experience and promote the advances of HSCT in Taiwan to gather everyone's experience and promote advances of HSCT in Taiwan. Compared with matched sibling donors, transplants from matched unrelated donors exhibited a trend of superior survival. In Taiwan, transplant donors showed remarkable growth from unrelated (24.8%) and haploidentical (10.5%) donors. The number of older patients (17.4%; aged ≥61 years) who underwent transplantation has increased markedly. This review summarizes several significant developments in HSCT treatment in Taiwan. First, the use of Anti-thymocyte globulin (ATG) and intravenous busulfan regimens were important risk factors for predicting hepatic sinusoidal obstruction syndrome. Second, a new, machine learning-based risk prediction scoring system for posttransplantation lymphoproliferative disorder has identified five risk factors: aplastic anemia, partially mismatched related donors, fludarabine use, ATG use, and acute skin graft-versus-host disease. Third, although the incidence of idiopathic pneumonia syndrome was low (1.1%), its mortality rate was high (58.1%). Fourth, difficult-to-treat mantle cell and T-cell lymphomas treated with autologous HSCT during earlier remission had higher survival rates. Fifth, treatment of incurable multiple myeloma with autologous HSCT showed a median progression-free survival and overall survival of 46.5 and 70.4 months, respectively. Sixth, different haploidentical transplantation strategies were compared. Seventh, caution should be taken in administering allogeneic HSCT treatment in older patients with myeloid leukemia with a Charlson Comorbidity Index ≥3 because of a higher risk of nonrelapse mortality.

Background: Allo-HSCT is a curative therapy for patients with transfusion-dependent thalassemia (TDT). The high incidence of transplant-related complications is becoming an obstacle to safe and effective unrelated donor (URD) transplantation.
Methods: In this retrospective study, we reported the survival outcomes and complications of transplantation in thalassemia patients using a novel regimen consisting of pre-transplantation immunosuppression (PTIS) and modified myeloablative conditioning based on intravenous busulfan, cyclophosphamide, fludarabine, and rabbit anti-human thymocyte immunoglobulin.

Purpose: Graft-versus-host disease (GVHD) is a common complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). GVHD may affect several organs, including ocular manifestations, ranging from dry eye syndrome to sight-threatening corneal ulceration or perforation. Limited information is available about characteristics and treatments of ocular GVHD and its relation to general prognosis.

Fatty acid oxidation is of uncertain importance in most stem cells. We show by C-palmitate tracing and metabolomic analysis that hematopoietic stem/progenitor cells (HSPCs) engage in long-chain fatty acid oxidation that depends upon carnitine palmitoyltransferase 1a (CPT1a) and hydroxyacyl-CoA dehydrogenase (HADHA) enzymes. CPT1a or HADHA deficiency had little or no effect on HSPCs or hematopoiesis in young adult mice.

Objectives: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment for hematological diseases, with success rates improving due to advancements in conditioning regimens and new anti-graft versus host disease (GVHD) drugs. Ruxolitinib, an oral selective Janus kinase (JAK) 1 and 2 inhibitor has been used to mitigate the effects of various inflammatory and myeloproliferative syndromes, given the JAK kinase pathway's central role in cytokine signaling during inflammatory and immune processes. In this study we aimed to assess ruxolitinib's efficacy in patients with chronic GVHD (cGVHD).

Background: The management of relapsed acute lymphoblastic leukemia (ALL) after hematopoietic stem cell transplantation (HSCT) has evolved significantly. Initially, treatment options were limited to palliative care, salvage chemotherapy, and second HSCT. Currently, the focus has shifted to innovative immunotherapies, particularly CAR T-cell therapy.
