Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RATIONALE: Learning about the effect of excess iron in the liver of patients undergoing donor stem cell transplant may help doctors plan treatment.

PURPOSE: This study is investigating the effects of iron overload in patients undergoing donor stem cell transplant.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVES:

Primary

* Determine the impact of pre-transplant iron overload (defined as liver iron concentration \[LIC\] above normal \[\> 1.8 mg/g\] on an MRI of the liver measuring tissue proton transverse relaxation rates \[R2 MRI\]) on the probability of 1-year overall survival of patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT).

Secondary

* Determine the impact of pre-transplant iron overload on the composite endpoint of non-relapse mortality and complications (e.g., serious infections, hepatic veno-occlusive disease, or organ failure) within 1 year after allogeneic HSCT.
* Determine the impact of pre-transplant iron overload on the 1-year cumulative incidence of acute or chronic graft-vs-host disease in patients with acute leukemia or myelodysplastic syndromes undergoing allogeneic HSCT.
* Determine the impact of pre-transplant iron overload on the 1-year probability of overall survival and non-relapse mortality in patients undergoing allogeneic HSCT.
* Determine the prevalence of pre-transplant iron overload in adult patients undergoing allogeneic HSCT.
* Determine the correlation between pre-transplant ferritin levels and LIC on R2 MRI.
* Compare the longitudinal measures of serum ferritin levels after allogeneic HSCT in patients with iron overload vs those without iron overload.
* Estimate the cumulative incidence of iron overload at 1 year after allogeneic HSCT.

OUTLINE: Patients undergo blood sample collection to measure serum ferritin levels at baseline (pre-transplant) and then at 3, 6, 9, and 12 months after transplant. Patients with serum ferritin \> 500 ng/mL also undergo an R2 MRI at baseline (pre-transplant) and at 12 months after transplant to determine liver iron concentration. Patients with serum ferritin \> 500 ng/mL at 12 months after transplant also undergo an R2 MRI.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Without Iron Overload

Patients entering study without pre-HSCT iron-overload. Iron overload will be defined as liver ion concentration (LIC above normal (\>1.8 mg/g) on R2 magnetic resonance imaging (MRI) of the liver.

magnetic resonance imaging

Intervention Type PROCEDURE

MRI of the liver will be performed within 30 days prior to HSCT (day 0) and can be done during receipt of conditioning regimen chemotherapy and/or radiation therapy. MRI will also be performed in selected patients at 1 year post-HSCT. This MRI will be done within ± 30 days of their 1-year post-transplant followup date.

The R2 MRI is a specific MRI technique and cannot be used for the purpose of general diagnostic imaging. In our study, this modality is being used specifically for the estimation of LIC.

Serum ferritin

Intervention Type PROCEDURE

Blood samples will be taken pre-transplant, 3, 6, 9 and 12 months post-transplant

With Iron-Overload

Patients entering study with pre-HSCT iron-overload. Iron overload will be defined as liver ion concentration (LIC above normal (\>1.8 mg/g) on R2 magnetic resonance imaging (MRI) of the liver.
