Autologous Peripheral Blood Stem Cell Mobilization and Transplantation for Myelofibrosis
OBJECTIVES: I. Determine the ability of myeloablative chemotherapy followed by peripheral
blood stem cell (PBSC) transplantation to restore effective marrow hematopoieses in patients
with advanced idiopathic myelofibrosis or myelofibrosis secondary to other
myeloproliferative disorders. II. Determine the ability of this regimen to palliate symptoms
and prolong survival in these patients. III. Determine if there is evidence of clonal
hematopoieses before PBSC mobilization, in the PBSC product, and after transplantation in
these patients. IV. Correlate the properties of the peripheral blood before mobilization and
the PBSC product with engraftment in these patients. V. Correlate the markers of
angiogenesis with clinical parameters in these patients.
OUTLINE: Patients with evidence of leukemic progression receive cytoreduction therapy
consisting of idarubicin IV on days 1-3 and cytarabine IV continuously over days 1-7
followed by filgrastim (G-CSF) subcutaneously (SC) daily until blood counts recover and
leukapheresis is completed. Patients undergo leukapheresis beginning when blood counts
recover and continuing until the target number of cells are collected. Patients with no
evidence of leukemic progression receive filgrastim SC daily until leukapheresis is
completed. Patients undergo leukapheresis beginning on day 4 and continuing until the target
number of cells are collected. Patients receive myeloablative therapy consisting of oral
busulfan every six hours on days -5 to -2. Patients with leukemic progression begin
myeloablative therapy at least 28 days after completion of chemotherapy. Patients receive
autologous peripheral blood stem cells IV on day 0. Patients are followed at 1 month, 3
months, 1 year, and then annually thereafter.
PROJECTED ACCRUAL: A total of 10-44 patients will be accrued for this study within 2 years.
Inclusion Criteria
DISEASE CHARACTERISTICS: Diagnosis of idiopathic myelofibrosis or other myeloproliferative
disorder with myelofibrosis Evidence of advanced disease or hematologic abnormalities due
to severe fibrosis such as 1 or more of the following poor prognostic factors: Hemoglobin
less than 10 g/dL Platelet count less than 100,000/mm3 WBC less than 4,000/mm3 Symptomatic
splenomegaly Constitutional symptoms inadequately controlled with low dose chemotherapy
Abnormal karyotype Patients without evidence of advanced disease undergo PBSC harvest and
transplantation is delayed until there is evidence of disease progression Leukemia
progression (greater than 15% peripheral blood blasts) allowed if the history of a chronic
myeloproliferative disorder of at least 6 months duration is well documented Ineligible
for or refusal of allogeneic transplantation No other cause of myelofibrosis other than
myeloproliferative disorders, such as the following: Metastatic carcinoma Lymphoma Hairy
cell leukemia Myelodysplastic syndrome De novo acute leukemia Collagen vascular disorders
Granulomatous infections
