Examining the link between donor telomere length and outcomes in acute leukemia patients after stem cell transplantation

The First Affiliated Hospital, Zhejiang University School of Medicine

Observational Zhejiang University · NCT06076226

This study is trying to see if the length of telomeres in blood from stem cell donors can affect how well patients with acute leukemia do after their transplant.

What this trial studies

This observational study analyzes the relationship between donor leukocyte telomere length and the prognosis of patients with acute leukemia who have undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT). It includes patients aged 5 years and older who achieved complete remission and full donor chimerism post-transplant. The study assesses donor blood samples for telomere length prior to granulocyte colony-stimulating factor mobilization. The research is conducted at two major hospitals in China, ensuring ethical compliance and informed consent.

Who should consider this trial

Good fit: Ideal candidates are patients aged 5 years and older with acute leukemia who have undergone their first allo-HSCT and achieved complete remission.

Not a fit: Patients with non-acute leukemia diagnoses or those who did not achieve full donor chimerism after transplantation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how donor characteristics influence patient outcomes, potentially leading to improved transplant strategies.

How similar studies have performed: While similar studies have explored donor characteristics in transplantation, this specific focus on telomere length in acute leukemia is relatively novel.
