High-Altitude Hematology Observation-Stem Cell Transplantation (HALO-SCT)

The High-Altitude Hematology Observation-Stem Cell Transplantation (HALO-SCT) study is the first prospective real-world cohort of hematologic diseases and transplantation in the Qinghai-Tibet Plateau. Patients undergoing hematopoietic stem cell transplantation (HSCT) at Qinghai University Affiliated Hospital, together with their donors, are systematically enrolled. The registry collects demographic, diagnostic, treatment, prognosis, and medical expense information, as well as biospecimens for future analyses. Historical data are incorporated, and prospective data collection is ongoing with long-term follow-up planned. The registry is designed as a sustainable research infrastructure to provide comprehensive data on disease incidence, treatment patterns, outcomes, and resource utilization in a high-altitude setting.

The Kinetics Profiling of Immune Reconstitution and Clinical Outcomes

Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic malignancy with poor prognosis. Allogeneic hematopoietic stem cell transplantation (HSCT) remains the only potentially curative treatment. Immune reconstitution (IR) is critical for improving HSCT efficacy and quality of life among survivors, yet its dynamic impact on survival and complications like chronic graft-versus-host disease (cGVHD) in CMML is poorly defined. This study aimed to investigate the dynamics of IR following HSCT in patients with CMML and evaluate its impact on post-transplant clinical outcomes.
