Allogeneic Bone Marrow Transplantation for Hematologic Malignancies: A Treatment Approach Based on Risk of Relapse and Toxicity
OBJECTIVES:
- Determine the progression free survival (PFS) and overall survival (OS) of patients
with low risk myeloid disorders or older allogeneic recipients who are treated with
high dose busulfan and cyclophosphamide and allogeneic bone marrow transplantation
(BMT).
- Determine the PFS and OS in patients with lymphoid and high risk myeloid disorders who
are treated with etoposide, total body irradiation, and allogeneic BMT.
- Evaluate the toxicities of these 2 regimens when combined with cyclosporine and
methotrexate as graft versus host disease prophylaxis in these patients.
- Evaluate the PFS and OS of allogeneic BMT in patients with multiple myeloma and chronic
lymphocytic leukemia.
OUTLINE:
- Regimen A: Patients with chronic myelogenous leukemia (CP1, AP/CP2) and other
myeloproliferative disorders, myelodysplastic disorders, acute myelogenous leukemia
(CR1), or multiple myeloma (not eligible to receive total body irradiation due to prior
radiation) are treated with high dose busulfan and cyclophosphamide followed by
allogeneic bone marrow transplantation (BMT). Patients receive oral busulfan every 6
hours on days -7 to -4 and cyclophosphamide IV over 1 hour on days -3 and -2.
Allogeneic bone marrow is infused on day 0.
- Regimen B: Patients with acute myelogenous leukemia (at least CR2, relapsed), acute
lymphoid leukemia (ALL), any acute leukemia with CNS involvement, multiple myeloma, or
chronic lymphocytic leukemia are treated with total body irradiation and etoposide
followed by allogeneic BMT. Patients receive total body irradiation (TBI) on days -7 to
-4 for a total of 11 fractions and etoposide IV over 4 hours on day -3. Male patients
with ALL receive a testicular boost in 2 fractions on 2 successive days during TBI.
Allogeneic bone marrow is infused on day 0.
Patients in both regimens receive cyclosporine and methotrexate as graft versus host disease
prophylaxis.
Patients are followed weekly for 3 months and then monthly for 1 year.
PROJECTED ACCRUAL: At least 50 patients with low risk myeloid disease, 50 patients with
lymphoid malignancies, and 60 patients with high risk myeloid disease will be accrued for
this study.
