Inotuzumab Ozogamicin and Low-Intensity Chemotherapy in Older Patients With Newly Diagnosed CD22 Philadelphia Chromosome-Negative B-Cell Precursor Acute Lymphoblastic Leukemia.

Purpose: The use of inotuzumab ozogamicin (InO), a conjugated anti-CD22 monoclonal antibody, is becoming a promising frontline treatment for older patients with ALL.

Patients And Methods: EWALL-INO is an open-label prospective multicenter phase II trial (ClinicalTrials.gov identifier: NCT03249870).

Nilotinib with or without cytarabine for Philadelphia-positive acute lymphoblastic leukemia.

We previously demonstrated that a reduced-intensity chemotherapy schedule can safely replace hyper-CVAD (cyclophosphamide-vincristine-doxorubicin [Adriamycin]-dexamethasone) cycle 1 when combined with imatinib in adults with Philadelphia-positive acute lymphoblastic leukemia. In the present randomized GRAAPH-2014 trial, we used nilotinib and addressed the omission of cytarabine (Ara-C) in consolidation. The primary objective was the major molecular response (MMR) rate measured by BCR::ABL1 quantification after cycle 4 (end of consolidation).

The Impact of DNMT3A Status on NPM1 MRD Predictive Value and Survival in Elderly AML Patients Treated Intensively.

Minimal residual disease (MRD) is now a powerful surrogate marker to assess the response to chemotherapy in acute myeloid leukemia (AML). mutation has been associated with adverse outcomes. In this study, we aimed to investigate the impact of status on NPM1 MRD predictive value for survival in a retrospective cohort of AML patients aged over 60 years old treated intensively.

Azacitidine for the treatment of relapsed and refractory AML in older patients.

The prognosis of patients older than 50 with relapsed or refractory AML is dismal. Azacitidine has been investigated in older AML patients. Here we report the outcome of 130 patients older than 50 years included in a multicenter patient named program of azacitidine after relapse (n=67) or induction failure (n=63) of intensive chemotherapy.

Azacitidine in untreated acute myeloid leukemia: a report on 149 patients.

Limited data are available on azacitidine (AZA) treatment and its prognostic factors in acute myeloid leukemia (AML). One hundred and forty-nine previously untreated AML patients considered ineligible for intensive chemotherapy received AZA in a compassionate patient-named program. AML diagnosis was de novo, post-myelodysplastic syndromes (MDS), post-MPN, and therapy-related AML in 51, 55, 13, and 30 patients, respectively.

Description and outcome of a cohort of 8 patients with WHIM syndrome from the French Severe Chronic Neutropenia Registry.

Background: WHIM syndrome (WS), a rare congenital neutropenia due to mutations of the CXCR4 chemokine receptor, is associated with Human Papillomavirus (HPV)-induced Warts, Hypogammaglobulinemia, bacterial Infections and Myelokathexis. The long term follow up of eight patients highlights the clinical heterogeneity of this disease as well as the main therapeutic approaches and remaining challenges in the light of the recent development of new CXCR4 inhibitors.

Objective: This study aims to describe the natural history of WS based on a French cohort of 8 patients.

Prognostic factors for response and overall survival in 282 patients with higher-risk myelodysplastic syndromes treated with azacitidine.

Prognostic factors for response and survival in higher-risk myelodysplastic syndrome patients treated with azacitidine (AZA) remain largely unknown. Two hundred eighty-two consecutive high or intermediate-2 risk myelodysplastic syndrome patients received AZA in a compassionate, patient-named program. Diagnosis was RA/RARS/RCMD in 4%, RAEB-1 in 20%, RAEB-2 in 54%, and RAEB-t (AML with 21%-30% marrow blasts) in 22%.

Long-term outcome of patients in the LNH-98.5 trial, the first randomized study comparing rituximab-CHOP to standard CHOP chemotherapy in DLBCL patients: a study by the Groupe d'Etudes des Lymphomes de l'Adulte.

We report the outcome of patients included in the LNH-98.5 study, which compared cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) to rituximab plus CHOP (R-CHOP) therapy in 399 patients with diffuse large B-cell lymphoma (DLBCL) aged 60 to 80 years, with a median follow-up time of 10 years. Clinical event information was updated in all living patients (with the exception of 3 patients) in 2009.

Fluorescence in situ hybridization characterization of ider(20q) in myelodysplastic syndrome.

Isochromosome of the long arm of chromosome 20 with loss of interstitial material [ider(20q)] is a variant of deletion of chromosome 20q and a rare abnormality in myelodysplastic syndrome (MDS). We studied seven cases with an ider(20q) in MDS. Fluorescence in situ hybridization (FISH) studies showed all proximal breakpoints to be consistently located in 20q11.

Bone morphogenetic protein antagonist gene NOG is involved in myeloproliferative disease associated with myelofibrosis.

In a case with secondary myelofibrosis occurring after essential thrombocythemia, cytogenetic analysis revealed an isolated translocation t(X;17)(q27;q22) in all cells. We found that a bacterial artificial chromosome (BAC) encompassing the breakpoint on chromosome 17 long arm contained only one gene, NOG. We therefore investigated the occurrence of this rare breakpoint in myeloproliferative disorders (MPDs).

Dysregulation and overexpression of HMGA2 in myelofibrosis with myeloid metaplasia.

Among cytogenetic studies of patients affected with myelofibrosis with myeloid metaplasia (MMM), a rare chronic myeloproliferative disorder, we found several reports of structural abnormalities of the long arm of chromosome 12. Two MMM patients had a balanced translocation involving 12q: t(4;12)(q32;q15) and t(5;12)(p14;q15), respectively. FISH (fluorescence in situ hybridization) analysis showed that BAC (bacterial artificial chromosome) RP11-366L20 overlaps the breakpoint in both cases.

Frequency of structural abnormalities of the long arm of chromosome 12 in myelofibrosis with myeloid metaplasia.

Among cytogenetic studies of 205 patients diagnosed as myelofibrosis with myeloid metaplasia, we found seven cases with structural abnormalities of the long arm of chromosome 12. The karyotype showed six balanced translocations, that is, t(4;12)(q33;q21), t(5;12)(p14;q21), t(1;12)(q22;q24), t(12;17)(q24;q11), t(7;12) (p11;q24), and t(1;12)(p12;q24), as well as other cytogenetic abnormalities such as del(12)(q21;q24) and inv(12) (p12q24). Some isolated cases involving the 12q21 region have also been described in the literature.

Primary anaplastic large-cell lymphoma in adults: clinical presentation, immunophenotype, and outcome.

Anaplastic, CD30+, large-cell lymphoma is now a well-recognized pathologic entity that accounts for 2% to 8% of all lymphomas. Recent progress has been made in the understanding of certain biologic features found in anaplastic large-cell lymphoma, but information about its clinical behavior, in comparison to other large-cell lymphomas, is limited. The pathologic review of a large multicenter study of the treatment of aggressive lymphoma identified 146 cases of anaplastic large-cell lymphoma (ALCL) on the basis of morphology and CD30 expression.

Prognostic factors in agnogenic myeloid metaplasia: a report on 195 cases with a new scoring system.

We studied the survival of 195 patients with agnogenic myeloid metaplasia (AMM) diagnosed between 1962 and 1992 in an attempt to stratify patients into risk groups. Median survival was 42 months. Adverse prognostic factors for survival were age > 60 years, hepatomegaly, weight loss, low hemoglobin level (Hb), low or very high leukocyte count (WBC), high percentage of circulating blasts, male sex, and low platelet count.

[Piperacilline/tazobactam combination+amikacin versus ceftazidime+amikacin in patients with neutropenia and fever. An open multicenter study. Groupe d'étude des Aplasies Fébriles].

Objectives: To evaluate the toxicity and effectiveness of piperacillin+tazobactam and amikacin compared with a reference treatment with ceftazidime and amikacin given as first line therapy in neutropenic patients with fever.

Methods: A multicentric randomized trial was conducted in 222 adults who had fever (38 degrees C for > 3 h) during a period of aplasia (white cell count < 0.5.

Tuberculosis associated haemophagocytic syndrome: two cases with a favourable outcome.

Haemophagocytic syndrome is a heterogenous disease characterized by disordered macrophage activation associated with viral, bacterial or parasitic infection. The few reports of haemophagocytosis occurring in the presence of mycobacterial infection show a high mortality rate and we present two further cases notable for their favourable issue. Rapidity of diagnosis and immediate treatment could explain the avoidance of a fatal outcome.
