Randomized Controlled Trial Clinical Trial
A new combination of carboplatin, high-dose cytarabine and cross-over mitoxantrone or idarubicin for refractory and relapsed acute myeloid leukemia.
High-dose cytarabine (HIDAC) and new anthracycline-type drugs (mitoxantrone, idarubicin) are the mainstay of several active regimens against relapsed and refractory acute myeloid leukemia (AML). The present study was undertaken to assess the feasibility, toxicity, and antileukemic activity of carboplatin (CBDCA) added to a combination of the two former agents. ⋯ R-2 was well tolerated, exerted a significant activity in high-risk AML, and is amenable to further improvements. However, the lack of long-term disease-free survivors indicates the need for innovative post-remission strategies.

Clinical Trial Controlled Clinical Trial
Collection of peripheral blood progenitor cells for autografting with low-dose cyclophosphamide plus granulocyte colony-stimulating factor.
The combination of high or intermediate-dose cyclophosphamide (CY) plus granulocyte colony-stimulating factor (G-CSF) is useful to mobilize hematopoietic progenitor cells to peripheral blood, but the patients require hospitalization. The aim of this study was to evaluate the efficiency of low-dose CY plus G-CSF (5 ug/kg/day s.c.) as an outpatient treatment in order to collect enough progenitor cells for hematopoietic rescue in autologous peripheral blood transplantation (APBSCT). ⋯ Considering a pre-established threshold of 2.5 x 10(6)/kg CD34+ cells to proceed to APBSCT, the mobilization therapy was successful in 64% of the patients but was unsuccessful in 10 patients (5 NHL, 4 HD and 1 MM). Hematopoietic recovery was complete and stable in all patients. Low-dose CY plus G-CSF is efficient to collect enough PBSC for hematopoietic rescue after myeloablative therapy in patients with lymphoprolipherative disorders or multiple myeloma.
