Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who are both donors and recipients of allogeneic HSCT.

Probably not a fit

Patients receiving autologous stem cell transplants will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study investigates the effects of donor clonal hematopoiesis on the long-term outcomes of recipients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). It involves both prospective and retrospective data collection from donors and recipients at Queen Mary Hospital in Hong Kong. The study will analyze genetic profiles through next-generation sequencing to determine the association between donor gene mutations and recipient outcomes, including graft function and disease relapse. Data will be collected at various time points, including before and after transplantation.

Why it matters

Potential benefit: If successful, this study could improve understanding of how donor genetic factors influence transplant outcomes, potentially leading to better patient management.

How similar studies have gone: While studies on donor genetic factors in HSCT are ongoing, this specific focus on donor clonal hematopoiesis is relatively novel.
