Low-Dose TBI and Fludarabine Followed by Nonmyeloablative Unrelated Donor Peripheral Blood Stem Cell Transplantation Using Enhanced Postgrafting Immunosuppression for Patients With Hematologic Malignancies and Renal Cell Carcinoma - A Multi-Center Trial.
Inclusion Criteria:
- Ages > 50 years with hematologic malignancies treatable by unrelated hematopoietic
stem cell transplantation (HSCT)
- Ages =< 50 years of age with hematologic diseases treatable by allogeneic HSCT who
through pre-existing medical conditions or prior therapy are considered to be at high
risk for regimen related toxicity associated with a conventional transplant (> 40%
risk of transplant related mortality [TRM]) or those patients who refuse a
conventional HSCT; 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 at the collaborating center; patients =< 50 years of age who
have received previous autologous transplantation do not require patient review
committee approval; all children < 12 years must be discussed with the FHCRC
principal investigator (PI) prior to registration
- 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:
- Intermediate or high grade non-Hodgkin lymphoma (NHL) - not eligible for
autologous HSCT or after failed autologous HSCT
- Low grade NHL - with < 6 month duration of complete remission (CR) between
courses of conventional therapy
- Chronic lymphocytic leukemia (CLL) - must have failed two lines of conventional
therapy and be refractory to fludarabine
- Hodgkin's disease (HD) - must have received and failed frontline therapy
- Multiple myeloma (MM) - must have received prior chemotherapy; consolidation of
chemotherapy by autografting prior to nonmyeloablative HSCT is permitted
- Acute myeloid leukemia (AML) - must have < 5% marrow blasts at the time of
transplant
- Acute lymphoblastic leukemia - must have <5% blasts at the time of transplant
- Chronic myelogenous leukemia (CML) - patients will be accepted in chronic phase
or accelerated phase; patients who have received prior autografts after high
dose therapy or have undergone intensive chemotherapy with PBSC autologous or
conventional HSCT for advanced CML may be enrolled provided they are in CR or
chronic phase (CP) and have < 5% marrow blasts at time of transplant
- Myelodysplastic syndromes (MDS)/myeloproliferative disorder (MPD) - only
patients with MDS/refractory anemia (RA) or MDS/refractory anemia with ringed
sideroblasts (RARS) will be eligible for this protocol; additionally patients
with myeloproliferative syndromes (MPS) will be eligible; those patients with
MDS or MPS with > 5% marrow blasts (including those with transformation to AML)
must receive cytotoxic chemotherapy and achieve < 5% marrow blasts at time of
transplant
- Renal cell carcinoma - must have evidence of disease not amenable to surgical
cure or history of or active metastatic disease by radiological and histologic
criteria
- DONOR: FHCRC matching allowed will be Grade 1.0 to 2.1; unrelated donors who are
prospectively:
- Matched for human leukocyte antigen (HLA)-A, B, C, DRB1 and DQB1 by high
resolution typing
- Only a single allele disparity will be allowed for HLA-A, B, or C as defined by
high resolution typing
- DONOR: A positive anti-donor cytotoxic crossmatch is an absolute donor exclusion
- DONOR: Patient and donor pairs homozygous at a mismatched allele are considered a
two-allele mismatch, i.e., the patient is A*0101 and the donor is A*0201, and this
type of mismatch is not allowed
- DONOR: PBSC only will be permitted as a hematopoietic stem cell (HSC) source on this
protocol
Exclusion Criteria:
- Patients with rapidly progressive intermediate or high grade NHL
- Renal cell carcinoma patients:
- With expected survival of less than 6 months
- Disease resulting in severely limited performance status (< 70%)
- Any vertebral instability
- History of brain metastases
- Central nervous system (CNS) involvement with disease refractory to intrathecal
chemotherapy
- 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 except renal cell carcinoma
- Fungal infections with radiological progression after receipt of amphotericin B or
active triazole for greater than 1 month
- Cardiac ejection fraction < 35%; ejection fraction is required if there is a history
of anthracycline exposure or history of cardiac disease
- Diffusion capacity of the lung for carbon monoxide (DLCO) < 40% and/or receiving
supplementary continuous oxygen
- The FHCRC PI of the study must approve of enrollment of all patients with pulmonary
nodules
- Patients with clinical or laboratory evidence of liver disease would be evaluated for
the cause of liver disease, its clinical severity in terms of liver function, and the
degree of portal hypertension; patients will be excluded if they are found to have
fulminant liver failure, cirrhosis of the liver with evidence of portal hypertension,
alcoholic hepatitis, esophageal varices, a history of bleeding esophageal varices,
hepatic encephalopathy, uncorrectable hepatic synthetic dysfunction evinced by
prolongation of the prothrombin time, ascites related to portal hypertension,
bacterial or fungal liver abscess, biliary obstruction, chronic viral hepatitis with
total serum bilirubin > 3 mg/dL, and symptomatic biliary disease
- Karnofsky scores < 60 (except renal cell carcinoma [RCC])
- Patients with > grade II hypertension by common toxicity criteria (CTC)
- Human immunodeficiency virus (HIV) positive patients
- The addition of cytotoxic agents for "cytoreduction" with the exception of
hydroxyurea and imatinib mesylate will not be allowed within two weeks of the
initiation of conditioning
- DONOR: Marrow donors
- DONOR: Donors who are HIV-positive and/or, medical conditions that would result in
increased risk for filgrastim (G-CSF) mobilization and harvest of PBSC
