Study Description
Brief Summary:
This clinical trial studies how well donor stem cell boost works in treating patients with low blood cells after donor stem cell transplant. Donor stem cell boost may increase low blood cell counts caused by hematologic cancer or its treatment.

Condition or disease Intervention/treatment
Anemia Hematopoietic/Lymphoid Cancer Lymphopenia Neutropenia Thrombocytopenia Biological: Allogeneic hematopoietic stem cell transplantation Biological: Peripheral blood stem cell transplantation Procedure: Management of therapy complications

Outcome Measures

Primary Outcome Measures :
  1. Etiologies of post HSCT cytopenias [ Time Frame: Up to 8 weeks ]
    Will be collected and reported descriptively.

  2. CD34+/kg and CD3+/kg cell doses in the infused CD 34+ selected boost products [ Time Frame: Up to 8 weeks ]
    Will be collected and reported descriptively.

  3. Effects of the CD 34+ selected boost on peripheral blood cell counts [ Time Frame: Up to 8 weeks ]
    Will be collected and reported descriptively.

  4. Incidence of GVHD related to the CD34+ selected boost [ Time Frame: Up to 8 weeks ]

  5. Incidence of grade 3-5 infusion reactions, graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0 [ Time Frame: Up to 8 weeks ]
    Will be descriptive.

  6. Incidence of severe GVHD (grades 3-4), graded according to standard criteria [ Time Frame: Up to 8 weeks ]
    Will be descriptive.
