Dasatinib in high-risk core binding factor acute myeloid leukemia in first complete remission: a French Acute Myeloid Leukemia Intergroup trial.

Core-binding factor acute myeloid leukemia is a favorable acute myeloid leukemia subset cytogenetically defined by t(8;21) or inv(16)/t(16;16) rearrangements, disrupting RUNX1 (previously CBFA/AML1) or CBFB transcription factor functions. The receptor tyrosine kinase KIT is expressed in the vast majority of these acute myeloid leukemias and frequent activating KIT gene mutations have been associated with a higher risk of relapse. This phase II study aimed to evaluate dasatinib as maintenance therapy in patients with core-binding factor acute myeloid leukemia in first hematologic complete remission, but at higher risk of relapse due to molecular disease persistence or recurrence.

Core-binding factor acute myeloid leukemia in first relapse: a retrospective study from the French AML Intergroup.

Although core-binding factor-acute myeloid leukemia (CBF-AML) (t[8;21] or inv[16]/t[16;16]) represents a favorable cytogenetic AML subgroup, 30% to 40% of these patients relapse after standard intensive chemotherapy. The encouraging results of gemtuzumab ozogamicin (GO) in newly diagnosed AML, and particularly in CBF-AML, incited us to retrospectively investigate the impact of GO-based salvage in these patients. We retrospectively analyzed the outcome of 145 patients with CBF-AML (59 t[8;21], 86 inv[16]/t[16;16]) in first relapse.

Fatal-mixed cutaneous zygomycosis-aspergillosis: a case report.

Mucorales and Aspergillus are molds responsible for infections in immunocompromised patients. In this report, we describe a case of a rare extensively mixed cutaneous infection caused by Lichtheimia ramosa, Aspergillus fumigatus and Aspergillus terreus in a neutropenic patient suffering from an acute leukemia. The fatal outcome of this patient can be attributed to its hematologic malignancy, the extensive nature of the lesions and the resistance of the strains to antifungals.

A galactosidase-responsive doxorubicin-folate conjugate for selective targeting of acute myelogenous leukemia blasts.

Cytarabine combined with an anthracycline or an anthracenedione represents the usual intensive induction therapy for the treatment of AML. However, this protocol induces severe side effects and treatment-related mortality due to the lack of selectivity of these cytotoxic agents. In this paper, we present the study of the first galactosidase-responsive molecular "Trojan Horse" programmed for the delivery of doxorubicin exclusively inside AML blasts over-expressing the folate receptor (FR).

Fanconi syndrome and chronic kidney disease in paroxysmal nocturnal hemoglobinuria: effect of eculizumab therapy.

The association of Fanconi syndrome (FS) and chronic kidney disease (CKD) has been rarely described during the course of paroxysmal nocturnal hemoglobinuria (PNH). We report 2 patients with PNH and CKD associated with proximal tubule dysfunction, which manifested as full-blown FS in one case. In both patients, abnormal iron load within the kidneys was demonstrated by magnetic resonance imaging, which correlated with diffuse and numerous hemosiderin inclusions within proximal tubular cells.

Early matched sibling hematopoietic cell transplantation for adult AML in first remission using an age-adapted strategy: long-term results of a prospective GOELAMS study.

The LAM2001 phase 3 trial, involving 832 patients with acute myeloid leukemia (AML; median: 46 years) proposed HLA-identical sibling allograft HSCT for all patients with an identified donor. The trial compared reduced-intensity conditioning (RIC) for patients older than 50 years of age (N = 47) and myeloablative conditioning for younger patients (N = 117). BM HSCT was performed in the younger patients, while the older ones received a consolidation course, followed by peripheral blood allo-HSCT using RIC.

Bortezomib plus dexamethasone versus reduced-dose bortezomib, thalidomide plus dexamethasone as induction treatment before autologous stem cell transplantation in newly diagnosed multiple myeloma.

The Intergroupe Francophone du Myelome conducted a randomized trial to compare bortezomib-dexamethasone (VD) as induction before high-dose therapy (HDT) and autologous stem cell transplantation (ASCT) to a combination consisting of reduced doses of bortezomib and thalidomide plus dexamethasone (vtD) in patients with multiple myeloma. Overall, a total of 199 patients were centrally randomly assigned to receive VD or vtD. After 4 cycles, the complete response (CR) rate was the same in both groups (13% in the vtD arm, 12% in the VD arm, P = .

Dismal prognostic value of monosomal karyotype in elderly patients with acute myeloid leukemia: a GOELAMS study of 186 patients with unfavorable cytogenetic abnormalities.

The prognosis of acute myeloid leukemia (AML) is very poor in elderly patients, especially in those classically defined as having unfavorable cytogenetics. The recent monosomal karyotype (MK) entity, defined as 2 or more autosomal monosomies or combination of 1 monosomy with structural abnormalities, has been reported to be associated with a worse outcome than the traditional complex karyotype (CK). In this retrospective study of 186 AML patients older than 60 years, the prognostic influence of MK was used to further stratify elderly patients with unfavorable cytogenetics.

Breakthrough Hormographiella aspergillata infections arising in neutropenic patients treated empirically with caspofungin.

Hormographiella aspergillata, a filamentous basidiomycete, has rarely been involved in human infections. We describe 2 febrile neutropenic patients who developed a severe pulmonary infection due to H. aspergillata while receiving empirical caspofungin therapy for presumed fungal pneumonia.

Bortezomib and high-dose melphalan as conditioning regimen before autologous stem cell transplantation in patients with de novo multiple myeloma: a phase 2 study of the Intergroupe Francophone du Myelome (IFM).

Autologous stem cell transplantation (ASCT) is recommended for younger patients with newly diagnosed multiple myeloma. Achieving complete response (CR) or at least very good partial response (VGPR) is a major prognostic factor for survival with 20% to 30% of patients achieving CR after ASCT. Bortezomib has shown synergistic effects with melphalan and no prolonged hematologic toxicity.
