PRIMARY OBJECTIVES:
I. To assess the safety and efficacy of 1.5 mCi/kg (max 120 mCi) 90Y-Ibritumomab tiuxetan (yttrium Y 90 ibritumomab tiuxetan) (anti-CD20) combined with fludarabine (fludarabine phosphate) (30 mg/m^2 x 3) and 2 gray (Gy) total body irradiation followed by human leukocyte antigens (HLA) matched allogeneic hematopoietic transplantation for patients with relapsed or refractory aggressive B-cell lymphoma.
OUTLINE:
Beginning 24-48 hours prior to therapy infusion, patients receive rituximab intravenously (IV) over 4-6 hours and then receive a therapy-dose of high-dose yttrium Y 90 ibritumomab tiuxetan IV over 30 minutes on day -14 prior to transplant. Patients also receive fludarabine phosphate IV on days -4 to -2 and undergo TBI followed by allogeneic PBSCT on day 0. Patients also receive cyclosporine orally (PO) twice daily (BID) on days -3 to 56 with taper to day 180 (related donor) or -3 to 100 with taper over 11 weeks (unrelated donor) and mycophenolate mofetil PO BID on days 0-27 (related donor) or PO thrice daily (TID) on days 0-40 with taper to day 96 (unrelated donor).
After completion of study treatment and assessments through ~day 100 following transplant, patients are followed up at 1, 3, 6, and 12 months and then annually up to 2 years thereafter.

- Progression-free Survival [ Time Frame: 1 year ]Based on a one-sample chi-square test with one-sided significance level of five percent. This study will be deemed successful if the 1 year progression-free survival of this highest-risk group of patients is 54% or greater.
- Absolute Neutrophil Count (ANC) Engraftment [ Time Frame: Up to day 100 ]The median time in days to achieve ANC recovery defined as ANC>500uL.
- Overall Survival [ Time Frame: Up to 2 years post transplant ]
- Response Rates [ Time Frame: Day 100 ]Response is defined as having achieved a Partial Response or better.
- Treatment-related Mortality [ Time Frame: Day 100 ]Defined as death in the absence of progressive lymphoma that can be possibly, probably, or definitely attributed to the radioimmunotherapy.
- Platelet Engraftment [ Time Frame: Up to day 100 ]The median time in days to achieve platelet recovery as defined as platelet >20,000uL.
- Hematopoietic Toxicity [ Time Frame: Up to day 100 ]Clinical sequelae due to hematopoietic toxicity as defined by incidences of neutropenic fever and bleeding.
