Cousin vs. Sibling Donors in Haplo-HSCT
16. juni 2026 opdateret af: The First Affiliated Hospital of Soochow University
Comparison of Outcomes of Haploidentical Hematopoietic Stem Cell Transplantation From Cousin Donors Versus Sibling Donors in Patients With Hematological Malignancies: A Target Trial Emulation Study
This observational study aims to emulate a hypothetical pragmatic, multicenter, non-blinded clinical trial enrolling adult patients undergoing haploidentical hematopoietic stem cell transplantation (haplo-HSCT) with grafts derived from either cousin or sibiling donors.
The main research question is whether cousin donor-derived haplo-HSCT is associated with inferior clinical outcomes relative to sibling donor-derived haplo-HSCT.
Study participants consist of adult patients diagnosed with hematological malignancies who underwent cousin or sibiling haplo-HSCT between 2017 and 2024, and all eligible recipients will receive regular follow-up assessments.

Studiebefolkning
This multicenter, retrospective observational study included adult patients with hematological malignancies undergoing their first haploidentical hematopoietic stem cell transplantation at four clinical centers between 2017 to 2024.
Eligible patients were identified through retrospective clinical records and stratified by donor kinship recorded at transplant, classified as either cousin or sibling donor graft recipients.
Beskrivelse
Inclusion Criteria:
- Adult patients diagnosed with hematological malignancies, including acute leukemia (AL), chronic myeloid leukemia (CML), myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN), and non-Hodgkin lymphoma (NHL)
- Receipt of first haploidentical hematopoietic stem cell transplantation between 2017 and 2024
- Documented exact date of transplantation available in medical charts
- Verifiable donor kinship classified as either cousin or sibiling
- Complete longitudinal follow-up data accessible for outcome assessment
Exclusion Criteria:
- Prior receipt of any form of hematopoietic stem cell transplantation
- An age difference of more than 18 years between the donor and recipient
- Failure of successful infusion of donor-derived hematopoietic stem cells following conditioning regimen
