Using imaging and blood tests to predict transplant failure after stem cell transplants

Official title: Imaging and Blood Biomarkers to Predict Graft Failure after HSCT

Funded at Emory University · NIH-10672998 · Data updated 2026-11-12

This study is looking at new ways to spot early signs of graft failure in patients who have had a stem cell transplant, using special imaging and blood tests to help doctors catch problems sooner and provide better care, especially for those getting cord blood or family donor transplants.

Who could benefit from this research

Could help

Ideal candidates for this research are patients receiving cord blood or haplo-identical HSCT who are at high risk for graft failure.

Less likely to help

Patients who are not undergoing HSCT or those who have already experienced graft failure may not benefit from this research.

What this research studies

This research investigates how novel imaging techniques and blood biomarkers can help detect early signs of graft failure in patients who have undergone allogeneic hematopoietic stem cell transplantation (HSCT). By identifying subclinical engraftment, the study aims to expedite diagnosis and potential rescue through re-transplantation. The approach includes using (18)F-fluorothymidine (FLT) PET/CT imaging and measuring thymidine kinase 1 (TK1) levels in the blood to monitor cellular recovery. This could lead to timely interventions for patients at high risk of graft failure, particularly those receiving cord blood or haplo-identical transplants.

Why it matters

Potential benefit: If successful, this research could significantly improve the early detection of graft failure, leading to better outcomes for patients undergoing stem cell transplants.

How similar studies have gone: Previous studies have shown promising results with similar imaging and biomarker approaches, indicating potential for success in this research.
