Induction Therapy with Idarubicin, Ara-C, and VP-16, Followed by G-CSF and Maintenance Immunotherapy with Interleukin-2 for High-Risk AML
Aggressive chemotherapy followed by administration of G-CSF and maintenance therapy with interleukin-2 was evaluated in 16 patients with advanced myelodxysplastic syndrome, 47 patients with AML evolving from myelodysplastic syndromes, 3 patients with subacute myeloid leukemia and 5 patients with secondary AML. Median age was 59 years (range: 23 to 76 years). All patients achieving a complete remission (CR) after two induction courses went on to receive two consolidation courses, to be followed by randomization to either high-dose or low-dose IL-2 to evaluate the potential of IL-2 to eliminate residual leukemic cells and to prolong the duration of CR. Patients ≤ age 55 with an HLA identical …
Incidence of lineage promiscuity in acute myeloblastic leukemia: Diagnostic implications of immunoglobulin and T-cell receptor gene rearrangement analysis and immunological phenotyping
Abstract Sixty-nine blood or bone marrow samples from both children and adults with acute myeloblastic leukemia (AML) were investigated to elucidate the frequency of immunoglobulin (IG) and T-cell receptor (TCR)-gene rearrangements. Non-germline configuration for the IG heavy chain (h) gene was detected in the specimens of nine patients of various subtypes according to the French-American-British classification (FAB), including FAB M1, M2, M4 and M5. Rearrangement of the IG kappa chain (k) gene was present in one of these cases which simultaneously revealed a rearranged TCR-beta (b) chain gene. In another two AML samples we found TCR-b gene rearrangements, in one case in combination with an…
