About
This clinical trial studies fludarabine phosphate, low-dose total body irradiation, and donor stem cell transplant in treating patients with hematologic malignancies or kidney cancer. Giving chemotherapy drugs, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine before the transplant and cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.
Full description
PRIMARY OBJECTIVES:
I. To determine whether stable allogeneic engraftment from unrelated hematopoietic stem cell donors can be safely established using a non-myeloablative conditioning regimen in patients with hematologic malignancies and renal cell carcinoma.
SECONDARY OBJECTIVES:
I. To evaluate whether donor lymphocyte infusion (DLI) can be safely used in patients with mixed or full donor chimerism to eliminate persistent or progressive disease.
OUTLINE:
CONDITIONING REGIMEN: Patients receive fludarabine phosphate intravenously (IV) on days -4 to -2. Patients also undergo low-dose total-body irradiation (TBI) on day 0.
TRANSPLANTATION: Patients undergo allogeneic peripheral blood stem cell (PBSC) or bone marrow transplantation on day 0.
IMMUNOSUPPRESSION: Patients receive cyclosporine orally (PO) twice daily (BID) on days -3 to 100 with taper to day 177 and mycophenolate mofetil PO BID on days 0-40 with taper to day 96. Patients with mixed chimerism, persistent or progressive disease, and no evidence of graft-versus-host disease and who have been off immunosuppression for at least 2 weeks undergo DLI over 30 minutes. DLI may be repeated every 65 days for up to 3 doses.
After completion of study treatment, patients are follow-up periodically for 5 years.

Inclusion criteria
Age > 50 years with hematologic malignancies treatable by allogeneic hematopoietic stem cell transplant (HSCT) and all patients with B cell malignancies except those who may be cured by autologous stem cell transplantation (SCT)
Age =< 50 years of age with hematologic diseases treatable by allogeneic HSCT who through pre-existing medical conditions or prior therapy are considered to be of high risk for regimen related toxicity associated with a conventional transplant or those patients who refuse a conventional SCT; transplants must be approved for these inclusion criteria by both the participating institution's patient review committee such as the Patient Care Conference (PCC at the Fred Hutchinson Cancer Research Center [FHCRC]) and by the principal investigator
Patients with metastatic renal cell carcinoma with the histologic subtypes of clear cell, papillary and medullary may be accepted regardless of age
The following diseases will be permitted although other diagnoses can be considered if approved by PCC or the participating institution's patient review committees and the principal investigator
DONOR: Human leukocyte antigen (HLA) matched unrelated donor; donors should be matched for HLA -A, -B, -C, -developmentally regulated ribonucleic acid (RNA) binding protein 1(DRB)1 and -class II, DQ beta 1 (DQB) 1; HLA -A and -B loci should be matched at least to the level of resolution; HLA -C, -DRB1, and -DQB1 should be typed at the highest level of resolution available at the time of donor selection; donor must consent to either a bone marrow harvest or PBSC mobilization with filgrastim (G-CSF) arranged through the National Marrow Donor Program (NMDP) or other donor centers
Exclusion criteria
Patients with rapidly progressive intermediate or high grade NHL
Renal cell carcinoma patients with expected survival of less than 6 months
Any active central nervous system (CNS) involvement with disease
Fertile men or women unwilling to use contraceptive techniques during and for 12 months following treatment
Females who are pregnant
Patients with non-hematological tumors
Cardiac ejection fraction < 30%
Diffusion capacity of the lung for carbon monoxide (DLCO) < 30% and/or receiving supplementary continuous oxygen
Significant elevation of bilirubin and transaminases should be discussed at participating institutions' patient review committees in a case by case basis; evidence of synthetic dysfunction or severe cirrhosis will result in patient exclusion
Karnofsky score < 50 (except renal cell carcinoma [RCC])
Patients with poorly controlled hypertension on multiple antihypertensives
Human immunodeficiency virus (HIV) positive patients
