Outcome of older (≥70 years) APL patients frontline treated with or without arsenic trioxide-an International Collaborative Study

Data on outcome in older (≥70 years) patients with acute promyelocytic leukemia after treatment with arsenic trioxide (ATO) compared with standard chemotherapy (CTX) is scarce. We evaluated 433 patients (median age, 73.4 years) treated either with ATO+ all-trans retinoic acid (ATO/ATRA; n = 26), CTX/ATRA + ATO during consolidation (CTX/ATRA/ATO; n = 148), or with CTX/ATRA (n = 259). Median follow-up for overall survival (OS) was 4.8 years. Complete remissions (CR) were achieved in 92% with ATO/ATRA and 82% with CTX/ATRA; induction death rates were 8% and 18%, respectively. For analysis of postremission outcomes we combined the ATO/ATRA and CTX/ATRA/ATO groups (ATO/ATRA ± CTX). Cumulative incidence of relapse (CIR) was significantly lower after ATO/ATRA ± CTX compared with CTX/ATRA (P 10 × 10 9 /l) white blood cell (WBC) counts at diagnosis were associated with higher CIR (P < 0.001) compared with lower WBC in the CTX/ATRA group, but not in the ATO/ATRA ± CTX group (P = 0.48). ATO, when added to ATRA or CTX/ATRA is feasible and effective in elderly patients for remission induction and consolidation, particularly in patients with high WBC at diagnosis

Deferasirox in iron-overloaded patients with transfusion-dependent myelodysplastic syndromes: Results from the large 1-year EPIC study

PubMedID: 20451251The prospective 1-year EPIC study enrolled 341 patients with myelodysplastic syndromes (MDS); although baseline iron burden was >2500. ng/mL, ~50% were chelation-naïve. Overall median serum ferritin decreased significantly at 1 year (p=0.002). Decreases occurred irrespective of whether patients were chelation-naïve or previously chelated; changes were dependent on dose adjustments and ongoing iron intake. Sustained reductions in labile plasma iron were observed. Discontinuation rate (48.7%) and adverse event profile were consistent with previously reported deferasirox data in MDS. Alanine aminotransferase levels decreased significantly; change correlated significantly with reduction in serum ferritin (p<0.0001). This large dataset prospectively confirms the efficacy and well characterizes the safety profile of deferasirox in MDS. © 2010 Elsevier Ltd.NovartisContributions : NG, CF, MDP, PF, AG, AG-B, MS, KT, DV and CR served as investigators on this trial, enrolling patients and contributed to data interpretation, reviewed and provided their comments on this manuscript.

: Qual Life Res

International audiencePURPOSE: Tyrosine kinase inhibitors (TKIs) have dramatically improved the prognosis of chronic myeloid leukemia (CML). We aimed to assess health state utility and quality of life (QoL) in French patients with CML in real-life setting, to study the determinants of utility score and to compare health-related QoL values to general population norms. METHODS: We conducted a cross-sectional study in 412 patients with CML. Data were collected by electronic survey. Three patient-reported outcomes questionnaires were used: EORTC QLQ-C30, EORTC QLQ-CML24 and EuroQol EQ-5D-3L. Health state utility values were computed using the French value set. We computed deviations from reference norms from the general population. We studied the determinants of health utility score using multiple regression models. RESULTS: The mean utility score (SD) was 0.72 (0.25) in the chronic phase and 0.84 (0.21) in treatment-free remission, with marked variations by gender. Patients with CML had a deviation from the reference norm of -0.15 on average (SD: 0.25). In terms of QoL, social functioning, role functioning and cognitive functioning were notably impacted with a mean difference of -16.0, -13.1 and -11.7 respectively. Fatigue, dyspnea and pain were the symptoms with the highest deviation from general population norms (mean difference of 20.6, 14.0 and 8.3 respectively). In the multiple regression analysis, fatigue was the most important independent predictor of the utility score. CONCLUSION: Although TKIs prevent the disease from progressing and even allow remission without treatment, QoL in patients with CML is notably altered. The utility scores deteriorate with CML symptoms

Subcutaneous or intravenous administration of romiplostim in thrombocytopenic patients with myelodysplastic syndrome (MDS)

7009 Background: Thrombocytopenia is common in patients (pts) with MDS, and treatment options are currently limited to platelet (plt) transfusions. Romiplostim is an Fc-peptide fusion protein (peptibody) that stimulates plt production by the same mechanism as thrombopoietin. Methods: This was a phase II, multicenter, single arm, open-label study. Eligibility criteria included IPSS low or intermediate-1 risk MDS and a mean baseline plt count ≤50x10 9 /L. Safety and efficacy of romiplostim were evaluated in pts receiving 750μg romiplostim according to one of 3 schedules: weekly or biweekly subcutaneous injections (QWSC or Q2WSC), or biweekly intravenous injections (Q2WIV). Plt responses were measured per IWG 2006 criteria. Results: Of the 28 pts enrolled, 17 (61%) completed the study; 22 (79%) were male and the mean (±SD) baseline plt count was 29 (±10) x 10 9 /L. The mean age was 71 years and 19 pts (68%) had received plt transfusions in the past year. Mean duration of exposure to romiplostim was 12 (±8) weeks. The most common adverse events (AEs) were fatigue and headache (both 18%). Five pts experienced serious AEs, and there were 2 cases of disease progression to AML: one pt in the QWSC cohort who received romiplostim for 4 weeks and one in the Q2WSC cohort who received romiplostim for 20 weeks. For pts who completed 8 weeks treatment, 15/23 (65%) achieved a plt response, defined by IWG 2006 criteria, and 14/23 (61%) did not require a plt transfusion during this period. The small number of pts limited the ability to compare administration schedules; minor differences were observed in plt responses and plt transfusions, and the incidence of AEs appeared similar among cohorts. Conclusions: IV and SC romiplostim appeared well-tolerated and effective in raising plt counts and avoiding plt transfusions in low and intermediate-1 risk MDS pts. The dose recommendation for future studies is 750μg, given QW or Q2W SC. [Table: see text] [Table: see text

Clinical management of gastrointestinal disturbances in patients with myelodysplastic syndromes receiving iron chelation treatment with deferasirox

Item does not contain fulltextMyelodysplastic syndromes are characterized by ineffective hematopoiesis resulting in peripheral cytopenias. The majority of patients is dependent on regular transfusions of packed red blood cells leading to a secondary iron overload which might result in organ damage. Therefore, sufficient iron chelation therapy in selected patients is mandatory. Deferasirox (DFX) is an orally administered iron chelator which has been highly efficient in the treatment of secondary iron overload. Most frequent side effects of DFX are gastrointestinal disturbances, which leads in some patients to low adherence to the therapy. An expert panel met in Lisbon in July 2010 to develop recommendations on prevention and management of GI disturbances based on existing data and personal experiences
