I. To assess the safety of a modified peripheral blood (PB) graft for haploidentical transplantation, obtained by using depletion of naive, cluster of differentiation (CD)45RA+ T cells.
I. To estimate the proportion of patients with engraftment/graft failure. II. To determine the day 100 and 6 month non-relapse mortality (NRM). III. To estimate the cumulative incidence of grade 2-4 and 3-4 acute graft versus (vs.) host disease (aGVHD).
IV. To assess the rate of chronic GVHD within the first year post transplantation.
V. To assess immune reconstitution and the incidence of infectious episodes. VI. To assess disease response, disease-free survival (DFS) and overall survival (OS) after transplantation.
VII. To compare results with a retrospective cohort of patients treated with bone marrow graft on protocol 2009-0266.
Patients receive melphalan intravenously (IV) over 30 minutes on day -6 and fludarabine phosphate IV over 1 hour on days -6 to -3. Patients undergo total-body irradiation (TBI) on day -2 and CD45RA depleted peripheral blood stem cell transplantation on day 0. Patients also receive cyclophosphamide IV over 3 hours on days 3-4. Beginning on day 5, patients receive tacrolimus IV for 2 weeks and orally (PO) for at least 4 months. Beginning on day 7, patients receive filgrastim subcutaneously (SC) daily. Patients with CD20 positive lymphoma may receive rituximab IV on days -13, -6, 1, and 8.
After completion of study treatment, patients are followed up periodically.

Experimental: Treatment (peripheral blood stem cell transplantation)
Patients receive melphalan IV over 30 minutes on day -6 and fludarabine phosphate IV over 1 hour on days -6 to -3. Patients undergo TBI on day -2 and CD45RA depleted peripheral blood stem cell transplantation on day 0. Patients also receive cyclophosphamide IV over 3 hours on days 3-4. Beginning on day 5, patients receive tacrolimus IV for 2 weeks and PO for at least 4 months. Beginning on day 7, patients receive filgrastim SC daily. Patients with CD20 positive lymphoma may receive rituximab IV on days -13, -6, 1, and 8.
Drug: Fludarabine Phosphate
Other: Laboratory Biomarker Analysis
Procedure: Peripheral Blood Stem Cell Transplantation
Undergo CD45RA depleted peripheral blood stem cell transplantation
Given IV or PO
Radiation: Total-Body Irradiation
- Incidence of treatment failure defined as primary graft failure, grade 3-4 acute graft versus host disease (aGVHD), or non-relapse mortality [ Time Frame: Up to 100 days ]
- Immune reconstitution [ Time Frame: Up to 3 years ]Will be summarized by number of participants.
- Incidence of infectious episodes [ Time Frame: Up to 3 years ]Will be summarized by counts of participants .
- Disease free survival (DFS) time [ Time Frame: Up to 3 years ]Will be estimated using the method of Kaplan and Meier.
- Overall survival (OS) time [ Time Frame: Up to 3 years ]Will be estimated using the method of Kaplan and Meier.
