Brief summary
New conditioning regimens are still needed to maximize efficacy and limit treatment-related deaths of allogeneic transplantation for advanced hematologic malignancies. Over the past several years, the investigators have evaluated several new conditioning regimens that incorporate fludarabine, a novel immunosuppressant that has limited toxicity and that has synergistic activity with alkylating agents. Recent data have suggested that fludarabine may be used in combination with standard doses of oral or IV busulfan, thus reducing the toxicity previously observed with cyclophosphamide/ busulfan regimens.
Detailed description
Treatment-related mortality and recurrence of disease account for the majority of treatment failures in allogeneic transplantation for advanced hematologic malignancies. The most commonly utilized conditioning regimens consist of cyclophosphamide and total-body irradiation or busulfan and cyclophosphamide. Other agents such as etoposide or thiotepa are sometimes added to maximize the antileukemic effect. New conditioning regimens are however still needed to maximize efficacy and limit treatment-related deaths. Over the past several years, the investigators have evaluated several new conditioning regimens that incorporate fludarabine, a novel immunosuppressant that has limited toxicity and that has synergistic activity with alkylating agents. Recent data have suggested that fludarabine may be used in combination with standard doses of oral or IV busulfan, thus reducing the toxicity previously observed with cyclophosphamide/ busulfan regimens.
Interventions
All patients below age 55, should receive fludarabine/busulfan, and ATG in case of unrelated or mismatched donor, unless there is significant pulmonary, hepatic or cardiac damage: (E.g FEV1 \<40%, DLCO\<50%, LVEF\<40, Serum bilirubin \>1.5 mg% or serum transaminases \> 2x nl) and/or specific medical conditions such as preventing a standard myeloablative treatment, as per discussion with the PI.
All patients above age 55 or below age 65, should receive fludarabine/melphalan, and ATG, unless there is significant pulmonary, hepatic or cardiac damage: (E.g FEV1 \<40%, DLCO\<50%, LVEF\<40, Serum bilirubin \>1.5 mg% or serum transaminases \> 2x nl).
Patients receiving a transplant from a matched unrelated or mismatched related/unrelated donor would receive ATG in the conditioning regimen.

Recruitment details
We analyzed the clinical outcome of patients with hematological malignancies at standard or high-risk, who were transplanted (allogeneic peripheral blood or BMT HSCT) after receiving FluBU as a conditioning regimen. A total of 30 patients were recruited for this study which was conducted at the UIC Medical Center Inpatient BMT unit.
Pre-assignment details
Criteria for FluBu conditioning: \<60 years old; no diagnosis of myeloma or myelofibrosis (MF) in chronic phase; and not having received an autologous stem cell transplant with the last 2 years. Patients not fulfilling these criteria but still eligible for allogeneic transplantation were prepared with FluMel.
