Brief Summary
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors predict whether patients undergoing donor stem cell transplant will develop acute graft-versus-host disease. PURPOSE: This clinical trial is studying T cells to see how well they help in predicting acute graft-versus-host disease in patients undergoing donor stem cell transplant.

Outcome Measures
Primary Outcomes (1)
Percentage of regulatory T-lymphocytes (Tregs) at engraftment
percentage of Treg subsets present in patient's blood before they undergo stem cell transplant
day of stem cell transplant
Secondary Outcomes (1)
Association between Treg subsets and acute graft-vs.-host disease outcomes
at stem cell transplant and at day 28
Study Arms (1)
Allogeneic Stem Cell Transplant Patients
Patients undergoing allogeneic stem cell transplant (SCT). Potential study candidates will be identified by participating physicians.
Interventions
Lymphocyte Analysis: Lymphocyte subset studies will be performed on samples obtained from the patient, donor, or graft. Aliquots will be analyzed using standard flow cytometry.
Identification of gut-homing and skin-homing Treg subsets
Patient samples will receive an alphanumeric code assigned by the principal investigator so that patient and donor identity will be known only to study investigators and research staff. Clinical records on each patient will be reviewed by participating investigators or research staff on a routine basis so that relevant clinical information including survival, malignancy relapse, and GVHD can be included in the patient database. Flow cytometry results will also be included in this database.
Eligibility Criteria
People with a disease which is being treated with a bone marrow and/or a stem cell transplant.
You may qualify if:
- Patients undergoing allogeneic SCT
- Age \>= 18 years
You may not qualify if:
- Inability to give informed consent
- Patients who have not received an allogeneic SCT
- Any condition which, in the opinion of the investigator, might interfere with study objective
- Any reason which, in the opinion of the investigator, adds additional risk to the patient
