Iron chelation therapy associated with improvement of hematopoiesis in transfusion-dependent patients.

BACKGROUND: It is well known that iron overload may cause multiple organ failure. In chronically transfused patients, optimal iron chelation therapy is associated with reduced morbidity and mortality. Furthermore, chelation therapy has been associated with erythroid responses.

Quality of life in elderly patients with acute myeloid leukemia: patients may be more accurate than physicians

Background The aim of this study was to evaluate changes in quality of life scores and their association with therapy and survival in unselected elderly patients with acute myeloid leukemia. Design and Methods From February 2003 to February 2007, 113 patients aged more than 60 years with de novo acute myeloid leukemia were enrolled in a prospective observational study. Two different quality of life instruments were employed: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – C30 (EORTC QLQ-C30) and a health-related quality of life questionnaire for patients with hematologic diseases (QOL-E). Results Forty-eight patients (42.4%) received intensive chemotherapy and 65 (57.6%) were given palliative treatments. Age greater than 70 years (P=0.007) and concomitant diseases (P=0.019) had a significant impact on treatment allocation. At diagnosis, general quality of life was affected [median QOL-E standardized score 54, interquartile range 46–70; median EORTC global score 50, interquartile range 41–66]. Most patients were given a good ECOG Performance Status (< 2), which did not correlate with the patients’ perception of quality of life. At multivariate analysis, palliative approaches (P=0.016), age more than 70 years (P=0.013) and concomitant diseases (P=0.035) each had an independent negative impact on survival. In a multivariate model corrected for age, concomitant diseases and treatment option, survival was independently predicted by QOL-E functional (P=0.002) and EORTC QLQ-C30 physical function (P=0.030) scores. Conclusions Quality of life could have an important role in elderly acute myeloid leukemia patients at diagnosis as a prognostic factor for survival and a potential factor for treatment decisions.

Darbepoetin alfa for the treatment of anemia associated with myelodysplastic syndromes: efficacy and quality of life.

To evaluate efficacy, safety, changes in biological features, and quality of life (QoL) in low-risk anemic patients with MDS treated with darbepoetin alfa (DPO), 41 patients received DPO 150 μg weekly for 24 weeks. The dose was increased to 300 μg weekly in non-responsive patients. During treatment, 10/17 (59%) transfusion-dependent (TD) and 13/23 (56%) transfusion-free (TF) patients responded. In TF patients, Hb increased from 9.2 ± 0.9 g/dL to 10.3 ± 1.4 g/dL by 24 weeks (p = 0.004). The mean response duration was 22 weeks (95% CI: 19.7–24.0) in TF patients compared with 15.1 weeks (95% CI: 13.3–17.5) in TD patients. Response to treatment was associated with increases in QoL. Decreases in the percentage of apoptotic progenitor cells (p = 0.007) and CD34+ cells (p = 0.005) were observed. These results confirm previous studies demonstrating the safety and efficacy of DPO in anemic patients with MDS. Biological changes and improvement in QoL were associated with response. Adequate dosing is to be determined.

Lenalidomide in International Prognostic Scoring System Low and Intermediate-1 risk myelodysplastic syndromes with del(5q): an Italian phase II trial of health-related quality of life, safety and efficacy

Abstract In lower-risk myelodysplastic syndromes (MDS) with del(5q), lenalidomide induces erythroid responses associated with better survival. In a phase II, single-arm trial, 45 patients with anemia and lower-risk del(5q) MDS received lenalidomide 10 mg/day to evaluate quality of life (QoL) changes, measured by QOL-E, safety, responses and survival. Lenalidomide was well tolerated, with 80% completing ≥ 24 weeks of treatment. Earlier study discontinuation was related to disease progression (n = 5), death (n = 1) and withdrawal of consent (n = 3). Within 24 weeks, 82% obtained erythroid responses, durable in 69% at 52 weeks. Cytogenetic responses occurred in 29 patients (64%), with 10 patients achieving a complete cytogenetic response. QoL-E scores correlated with hemoglobin levels and improved in erythroid responders. Erythroid responders had an 86% reduced risk of disease progression and an 80% reduction in mortality risk compared with non-responders. These findings corroborate earlier studies and give further support to the use of lenalidomide in lower-risk MDS and del(5q).

Eltrombopag versus placebo for low-risk myelodysplastic syndromes with thrombocytopenia (EQoL-MDS): phase 1 results of a single-blind, randomised, controlled, phase 2 superiority trial

BACKGROUND In myelodysplastic syndromes, thrombocytopenia is associated with mortality, but treatments in this setting are scarce. We tested whether eltrombopag, a thrombopoietin receptor agonist, might be effective in improving thrombocytopenia in lower-risk myelodysplastic syndromes and severe thrombocytopenia. METHODS EQoL-MDS was a single-blind, randomised, controlled, phase 2 superiority trial of adult patients with low-risk or International Prognostic Scoring System intermediate-1-risk myelodysplastic syndromes and severe thrombocytopenia. Patients with a stable platelet count of lower than 30 × 109 platelets per L, aged at least 18 years, with refractoriness, ineligibility to receive treatment with alternative medications, or relapse while receiving treatment with alternative medications were included in this trial. Patients were randomly assigned (2:1) to receive eltrombopag (50 mg to 300 mg) or placebo for at least 24 weeks and until disease progression and were masked to treatment allocation. Here, we report the results in the intention-to-treat population of the first phase of the trial, for which the primary endpoints were the proportion of patients achieving a platelet response within 24 weeks and safety. The interim analysis presented here was protocol-specified and used a two-sided significance level of 0·001 and a p value at or below this limit for both primary endpoints to indicate the need for early trial termination. Duration of platelet transfusion independence, duration of response, overall survival, leukaemia-free survival, and pharmacokinetics will be reported at the end of the phase 2 portion of the trial. This trial is registered with EudraCT, number 2010-022890-33. FINDINGS Between June 13, 2011, and June 17, 2016, we enrolled 90 participants for the first phase of the trial. The median follow-up time to assess platelet responses was 11 weeks (IQR 4-24). Platelet responses occurred in 28 (47%) of 59 patients in the eltrombopag group versus one (3%) of 31 patients in the placebo group (odds ratio 27·1 [95% CI 3·5-211·9], p=0·0017). During the follow-up, 21 patients had at least one severe bleeding event (WHO bleeding score ≥2). There were a higher number of bleeders in the placebo (13 [42%] of 31 patients) than in the eltrombopag arm (eight [14%] of 59 patients; p=0·0025). 52 grade 3-4 adverse events occurred in 27 (46%) of 59 patients in the eltrombopag group versus nine events in five (16%) of 31 patients in the placebo group (χ2=7·8, p=0·0053, stopping rule not reached). The outcome acute myeloid leukaemia evolution or disease progression occurred in seven (12%) of 59 patients in the eltrombopag group versus five (16%) of 31 patients in the placebo group (χ2=0·06, p=0·81). INTERPRETATION Eltrombopag is well-tolerated in patients with lower-risk myelodysplastic syndromes and severe thrombocytopenia and is clinically effective in raising platelet counts and reducing bleeding events. The assessment of long-term safety and efficacy of eltrombopag and its effect on survival (phase 2 part of study) is still ongoing. FUNDING Associazione QOL-ONE.

Long-Term Results in Multiple Myeloma After High-Dose Melphalan and Autologous Transplantation According to Response Categories in the Era of Old Drugs

BACKGROUND The aim of this study was to investigate the correlation between the long-term prognosis of multiple myeloma (MM) and the quality of response to therapy in a cohort of 173 patients treated with high-dose melphalan (HDM) and autologous transplantation in the era of old drugs. PATIENTS AND METHODS A total of 173 patients with de novo MM who received a transplant between 1994 and 2010 were analyzed. VAD (vincristine, doxorubicin [Adriamycin], dexamethasone) was used as front-line regimen before auto-HPCT. The conditioning was HDM 200 mg/m(2). Patients were evaluated for clinical response using the criteria from the European Group for Blood and Marrow Transplantation, modified to include near complete remission (nCR) and very good partial remission (VGPR). RESULTS The response distribution after transplantation in our series was complete remission (CR) in 33 cases (19%), nearly complete remission (nCR) in 38 cases (22%), VGPR in 30 cases (17%), partial remission (PR) in 65 cases (38%), and stable disease (SD) in 7 cases (4%). Patients were followed for 48 ± 36 months. Median overall survival (OS) was not reached for the CR group. Progression-free survival (PFS) was 122 months for CR, 55 months for nCR, 56 months for VGPR, 32 months for PR, and 22 months for SD. Significant differences in PFS and OS were found between the CR and nCR groups (P = .003 and P = .001, respectively), between the CR and VGPR groups (P = .002 and P = .001, respectively), and between the CR and PR groups (P = .000 and P = .001, respectively). Responses were clustered in 3 main categories, ie, CR, nCR + VGPR + PR, and SD. The respective 10-year PFS and OS values were 58% and 70% for CR, 15% and 18% for nCR + VGPR + PR, and 0% and 0% for SD. CONCLUSION The achievement of depth and prolonged response represents the most important prognostic factor. The relapse rate is low for patients in CR after 10 years of follow-up, possibly signifying a cure.

Tolerability and efficacy of busulfan and fludarabine as allogeneic pretransplant conditioning therapy in acute myeloid leukemia: comparison with busulfan and cyclophosphamide regimen.

BACKGROUND The aim of this study was to compare safety and efficacy of the association of busulfan with cyclophosphamide (BuCy2) versus busulfan and fludarabine (BuFlu) as a conditioning regimen in allogeneic hematopoietic progenitor cell transplantation (allo-HPCT) in patients with acute myeloid leukemia (AML). PATIENTS AND METHODS A total of 65 consecutive patients who received an allo-HPCT from Human Leucocyte Antigen-matched sibling donors were analyzed. The conditioning was BuCy2 in 48 patients and BuFlu in 17 patients. RESULTS There were no significant differences between the 2 cohorts in hematological engraftment, incidence of extrahematological toxicities, and acute graft versus host disease (GVHD). The incidence of chronic GVHD was 34% in the BuCy2 group versus 57% in the BuFlu group (P = .03). Transplant-related mortality was 17% (8 patients) in the BuCy2 group versus 0 in the BuFlu arm. Disease-related mortality was similar in the whole study population; in high-risk AML patients it was 11% in the BuCy2 group and 19% in the BuFlu group (P = .015). The probability of disease-free and event-free survival at 2 years was, respectively, 70% and 60% in the BuCy2 group and 59% and 58% in the BuFlu group (P = .06 and P = not significant [ns]). The probability of overall survival at 2 years was 71% in the BuCy2 group and 63% in the BuFlu group (P = ns), and in the high-risk group it was 83% and 67% in the BuCy2 and BuFlu group, respectively (P = ns). CONCLUSION BuFlu is well tolerated and is less toxic than BuCy2 and our results did not suggest that in high-risk AML, BuCy2 should be the favorite regimen in terms of efficacy.
