I. To establish the safety of this treatment by determining its treatment-related mortality (TRM) within 30 days.
I. To estimate the relapse-free survival (RFS). II. To estimate the overall survival (OS). III. To quantify duration of infused allogeneic umbilical cord blood (UCB)-derived natural killer (NK) cells in the recipient.
PREPARATIVE REGIMEN: Patients receive carmustine intravenously (IV) over 2 hours on day -12, etoposide IV twice daily (BID) over 3 hours on days -11 to -8, cytarabine IV BID over 1 hour on days -11 to -8, melphalan IV over 30 minutes on day -7, and lenalidomide orally (PO) once daily (QD) on days -7 to -2 in the absence of disease progression or unacceptable toxicity. Patients who are CD20+ also receive rituximab IV over 3 hours on days -13 and -7.
NK-CELL INFUSION: Patients receive cord blood-derived expanded allogeneic NK cells IV over 1 hour on day -5 in the absence of disease progression or unacceptable toxicity.
STEM CELL TRANSPLANT: Patients undergo stem cell transplant IV over 30-60 minutes on day 0 in the absence of disease progression or unacceptable toxicity.
POST-TRANSPLANT: Patients receive filgrastim subcutaneously (SC) QD beginning on day +5. Treatment continues until white blood cell count recovers in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30, 100, and 180 days.

See Detailed Description.
Procedure: Autologous Hematopoietic Stem Cell Transplantation
Undergo stem cell transplant
Biological: Cord Blood-derived Expanded Allogeneic Natural Killer Cells
- Treatment-related mortality within 30 days (TRM30) [ Time Frame: Up to 30 days ]TRM30 will be estimated using a 95% credible interval assuming a beta(.50, .50) prior.
- Relapse-free survival (RFS) [ Time Frame: From the time of transplant assessed up to progression or relapse, assessed up to 3 years ]Unadjusted RFS will be estimated by the method of Kaplan and Meier.
- Overall survival (OS) [ Time Frame: From the time of transplant, assessed up to 3 years ]Unadjusted OS will be estimated by the method of Kaplan and Meier.
- Natural killer (NK) cell persistence [ Time Frame: Up to 14 weeks ]A Bayesian hierarchical regression model will be fit to the longitudinal NK cell data to assess its patterns over time and association with patient covariates, including type of lymphoma, age, and disease severity.
