The main objective of this study was to compare the reporting of health status and symptom severity, for a set of core symptoms related to imatinib therapy, between chronic myeloid leukemia patients ...and their treating physicians. Patients were asked to complete a questionnaire including questions on symptom severity and health status. The symptoms assessed were: abdominal discomfort, diarrhea, edema, fatigue, headache, muscle cramps, musculoskeletal pain, nausea and skin problems. The physicians were asked to complete a questionnaire for each of their patients entering the study. Four hundred twenty-two patients were included in the study. All respective paired physicians (n=29) completed the questionnaire, and thus the analyses are based on 422 patient-physician dyads. Agreement on symptom ratings ranged from 34% (for muscle cramps) to 66% (for nausea). For all symptoms, patients reported higher severity more often than their physicians. The three symptoms whose severity was most frequently underestimated by physicians were fatigue (51%), muscle cramps (49%) and musculoskeletal pain (42%). Health status was overestimated by physicians in 67% of the cases. Physicians and their patients with chronic myeloid leukemia often disagree in their ratings of the patients' symptom severity. Most typically, physicians tend to underestimate symptom severity and overestimate the overall health status of their patients. Current findings support the use of patient-reported outcome measures as a possible means to enhance the management of patients with chronic myeloid leukemia.
In the GIMEMA LAL 0904 protocol, adult Philadelphia positive acute lymphoblastic leukemia patients were treated with chemotherapy for induction and consolidation, followed by maintenance with ...imatinib. The protocol was subsequently amended and imatinib was incorporated in the induction and post-remission phase together with chemotherapy. Due to the toxicity of this combined approach, the protocol was further amended to a sequential scheme based on imatinib plus steroids as induction, followed by consolidation with chemotherapy plus imatinib and, when applicable, by a hematopoietic stem cell transplant. Fifty-one patients (median age 45.9 years) were enrolled in the final sequential protocol. At the end of induction (day +50), 96% of evaluable patients (n=49) achieved a complete hematologic remission; after consolidation, all were in complete hematologic remission. No deaths in induction were recorded. Overall survival and disease-free survival at 60 months are 48.8% and 45.8%, respectively. At day +50 (end of imatinib induction), a more than 1.3 log-reduction of BCR-ABL1 levels was associated with a significantly longer disease-free survival (55.6%, 95%CI: 39.0-79.3 vs. 20%, 95%CI: 5.8-69.1; P=0.03), overall survival (59.1%, 95%CI: 42.3-82.6 vs. 20%, 95%CI: 5.8-69.1; P=0.02) and lower incidence of relapse (20.5%, 95%CI: 7.2-38.6 vs. 60.0%, 95%CI: 21.6-84.3; P=0.01). Mean BCR-ABL1 levels remained significantly higher in patients who subsequently relapsed. Finally, BCR-ABL1
patients showed a significantly faster molecular response than BCR-ABL1
patients (P=0.023). Though the study was not powered to evaluate the role of allogeneic stem cell transplant, allografting positively impacted on both overall and disease-free survival. In conclusion, a sequential approach with imatinib alone in induction, consolidated by chemotherapy plus imatinib followed by a stem cell transplant is a feasible, well-tolerated and effective strategy for adult Philadelphia positive acute lymphoblastic leukemia, leading to the best long-term survival rates so far reported.

Summary Background The clinical presentation of myelodysplastic syndromes is highly variable and so accurate prediction of outcomes in these patients is crucial. We aimed to assess whether ...self-reported fatigue severity predicts overall survival beyond gold-standard prognostic indices in patients with higher-risk myelodysplastic syndromes. Methods We did a multicentre, prospective, observational, cohort study of patients from 37 centres in Europe, USA, and east Asia. Adults (≥18 years) with myelodysplastic syndromes were consecutively enrolled within 6 months of diagnosis with an intermediate-2-risk or high-risk score according to the International Prognostic Scoring System (IPSS). Patients were enrolled irrespective of older age, comorbidities, performance status, and progression from a lower IPSS risk score category. All patients had to complete a quality of life assessment at baseline. With use of univariate and then multivariate Cox proportional hazards regression analysis, we constructed a multivariate model of how prognostic variables, including IPSS and fatigue score from the European Organisation for Research and Treatment of Cancer quality-of-life questionnaire–core 30, predicted overall survival. The primary endpoint was overall survival by baseline self-reported fatigue scale ratings. This study was registered with ClinicalTrials.gov , number NCT00809575. Findings Between Nov 10, 2008, and Aug 13, 2012, we enrolled 280 patients with a median age of 71 years (IQR 64–77). The median follow-up was 15 months (IQR 8–27), and the last patient was assessed Feb 16, 2015. The median overall survival from diagnosis was 17 months (95% CI 15–19). In univariate analysis, the baseline factors that were significantly associated with reduced overall survival were increasing age, transfusion dependency (defined as having received at least one red blood cell transfusion every 8 weeks over a period of 4 months), Eastern Cooperative Oncology Group (ECOG) performance status of two or more, increased white blood cell count, high-risk IPSS score, and higher self-reported fatigue severity. In multivariate analysis, baseline factors independently associated with reduced overall survival were high-risk IPSS score (hazard ratio HR 2·525, 95% CI 1·357–4·697; p=0·0035) and a higher score for fatigue (1·110, 1·040–1·170, for every ten points of fatigue deterioration; p=0·0007). In further multivariate models for survival, including either the WHO-based prognostic scoring system or the revised version of the IPSS classification, fatigue remained a statistically significant independent prognostic factor with a HR of 1·120 (1·050–1·180, p=0.0003) and a HR of 1·130 (1·060–1·190, p=0·0002), respectively. Interpretation In patients with newly diagnosed higher-risk myelodysplastic syndromes, self-reported fatigue severity provides prognostic information for survival independent from gold-standard risk classifications. Our findings suggest that fatigue assessment should be included in routine diagnostic investigation for these patients and considered as a standard baseline stratification factor in future randomised controlled trials.

All-trans-retinoic acid (ATRA) has greatly modified the prognosis of acute promyelocytic leukemia; however, the role of maintenance in patients in molecular complete remission after consolidation ...treatment is still debated. From July 1993 to May 2000, 807 genetically proven newly diagnosed acute promyelocytic leukemia patients received ATRA plus idarubicin as induction, followed by 3 intensive consolidation courses. Thereafter, patients reverse-transcribed polymerase chain reaction–negative for the PML-RARA fusion gene were randomized into 4 arms: oral 6-mercaptopurine and intramuscular methotrexate (arm 1); ATRA alone (arm 2); 3 months of arm1 alternating to 15 days of arm 2 (arm 3); and no further therapy (arm 4). Starting from February 1997, randomization was limited to ATRA-containing arms only (arms 2 and 3). Complete remission was achieved in 761 of 807 (94.3%) patients, and 681 completed the consolidation program. Of these, 664 (97.5%) were evaluated for the PML-RARA fusion gene, and 586 of 646 (90.7%) who tested reverse-transcribed polymerase chain reaction–negative were randomized to maintenance. The event-free survival estimate at 12 years was 68.9% (95% confidence interval, 66.4%-71.4%), and no differences in disease-free survival at 12 years were observed among the maintenance arms.
To compare the antitumor efficacy of three different anthracyclines in combination with cytarabine and etoposide in adult patients with newly diagnosed acute myeloid leukemia (AML).
We randomly ...assigned 2,157 patients (age range, 15 to 60 years) to receive intensive induction-consolidation chemotherapy containing either daunorubicin, idarubicin, or mitoxantrone. After achieving complete remission (CR), patients were assigned to undergo either allogeneic or autologous stem-cell transplantation (SCT), depending on the availability of a sibling donor.
The overall CR rate (69%) was similar in the three groups. Autologous SCT was performed in 37% of cases in the daunorubicin arm versus only 29% and 31% in mitoxantrone and idarubicin, respectively (P < .001). However, the disease-free survival (DFS) and survival from CR were significantly shorter in the daunorubicin arm: the 5-year DFS was 29% versus 37% and 37% in mitoxantrone and idarubicin, respectively. The proportion of patients who underwent allogeneic SCT (22%) was equivalent in the three treatment groups, and the outcome was similar as well. The corrected 5-year overall survival rates were 31%, 34%, and 34%, corrected respectively.
In adult patients with AML who do not receive an allogeneic SCT, the use of mitoxantrone or idarubicin instead of daunorubicin enhances the long-term efficacy of chemotherapy.
Nucleophosmin (NPM) is a ubiquitously expressed nucleolar phoshoprotein which shuttles continuously between the nucleus and cytoplasm. Many findings have revealed a complex scenario of NPM functions ...and interactions, pointing to proliferative and growth-suppressive roles of this molecule. The gene NPM1 that encodes for nucleophosmin (NPM1) is translocated or mutated in various lymphomas and leukemias, forming fusion proteins (NPM-ALK, NPM-RARalpha, NPM-MLF1) or NPM mutant products. Here, we review the structure and functions of NPM, as well as the biological, clinical and pathological features of human hematologic malignancies with NPM1 gene alterations. NPM-ALK indentifies a new category of T/Null lymphomas with distinctive molecular and clinico-pathological features, that is going to be included as a novel disease entity (ALK+ anaplastic large cell lymphoma) in the new WHO classification of lymphoid neoplasms. NPM1 mutations occur specifically in about 30% of adult de novo AML and cause aberrant cytoplasmic expression of NPM (hence the term NPMc+ AML). NPMc+ AML associates with normal karyotpe, and shows wide morphological spectrum, multilineage involvement, a unique gene expression signature, a high frequency of FLT3-internal tandem duplications, and distinctive clinical and prognostic features. The availability of specific antibodies and molecular techniques for the detection of NPM1 gene alterations has an enormous impact in the biological study diagnosis, prognostic stratification, and monitoring of minimal residual disease of various lymphomas and leukemias. The discovery of NPM1 gene alterations also represents the rationale basis for development of molecular targeted drugs.
Recent reports of extramedullary disease (EMD) at recurrence in acute promyelocytic leukemia (APL) have raised increasing concern about a possible role of retinoic acid (RA) therapy.
We analyzed the ...risk of developing EMD localization at relapse in APL patients enrolled onto two consecutive studies of the Gruppo Italiano Malattie Ematologiche dell'Adulto. The studies investigated chemotherapy alone (LAP0389) versus RA plus chemotherapy (AIDA).
When all relapse types were taken into account, 94 (51%) of 184 patients and 131 (18%) of 740 patients who attained hematologic remission underwent relapse in the LAP0389 and AIDA studies, respectively (P < .0001). EMD localization was documented in five (5%) of 94 and 16 (12%) of 131 patients (P = .08). Hematologic and/or molecular relapse was diagnosed concomitantly in all but two patients with EMD in the AIDA study. For patients in the LAP0389 and AIDA series, the probability of EMD localization of any type at relapse was 3% and 4.5%, respectively (P = .79), while the probability of CNS involvement was 0.6% and 2% (P = .28). No significant differences were found with regard to mean WBC count and promyelocytic leukemia/retinoic acid receptor-alpha junction type in comparisons of patients with EMD and hematologic relapse.
APL patients receiving all-trans retinoic acid in addition to chemotherapy have no increased risk of developing EMD at relapse as compared with those treated with chemotherapy alone.
Treatment decision-making in patients with relapsed/refractory multiple myeloma (RRMM) is challenging for a number of reasons including, the heterogeneity of disease at relapse and the number of ...possible therapeutic approaches. This study broadly aims to generate new evidence-based data to facilitate clinical decision-making in RRMM patients. The primary objective is to investigate the prognostic value of patient self-reported fatigue severity for overall survival.
This multicenter prospective observational study will consecutively enroll 312 patients with multiple myeloma who have received at least 1 prior line of therapy and are considered as RRMM according to the International Myeloma Working Group (IMWG) criteria. Eligible RRMM participants will be adults (≥ 18 years old) patients and will be enrolled irrespective of comorbidities and performance status. At the time of study inclusion, data to calculate the frailty score are to be available. Patients will be followed up for 30 months and patient-reported outcome (PRO) assessment is planned at baseline and thereafter at 3, 6, 12, and 24 months. The following PRO validated questionnaires will be used: the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), the EORTC QLQ-MY20 and the EORTC QLQ-INFO25. Satisfaction with care and preference for involvement in treatment decisions will also be evaluated. Clinical, laboratory and treatment related information will be prospectively collected in conjunction with pre scheduled PRO assessments. Cox regression analyses will be used to assess the prognostic value of baseline fatigue severity (EORTC QLQ-C30) and other patient-reported health-related quality of life parameters.
Clinical decision-making in RRMM is a challenge and outcome prediction is also an important aspect to enhance personalized treatment planning. Given the paucity of PRO data in this population, this prospective observational study aims to provide novel information that may facilitate patients' management in routine practice.

To characterize gene expression signatures in acute lymphocytic leukemia (ALL) cells associated with known genotypic abnormalities in adult patients.
Gene expression profiles from 128 adult patients ...with newly diagnosed ALL were characterized using high-density oligonucleotide microarrays. All patients were enrolled in the Italian GIMEMA multicenter clinical trial 0496 and samples had >90% leukemic cells. Uniform phenotypic, cytogenetic, and molecular data were also available for all cases.
T-lineage ALL was characterized by a homogeneous gene expression pattern, whereas several subgroups of B-lineage ALL were evident. Within B-lineage ALL, distinct signatures were associated with ALL1/AF4 and E2A/PBX1 gene rearrangements. Expression profiles associated with ALL1/AF4 and E2A/PBX1 are similar in adults and children. BCR/ABL+ gene expression pattern was more heterogeneous and was most similar to ALL without known molecular rearrangements. We also identified a set of 83 genes that were highly expressed in leukemia blasts from patients without known molecular abnormalities who subsequently relapsed following therapy. Supervised analysis of kinase genes revealed a high-level FLT3 expression in a subset of cases without molecular rearrangements. Two other kinases (PRKCB1 and DDR1) were highly expressed in cases without molecular rearrangements, as well as in BCR/ABL-positive ALL.
Genomic signatures are associated with phenotypically and molecularly well defined subgroups of adult ALL. Genomic profiling also identifies genes associated with poor outcome in cases without molecular aberrations and specific genes that may be new therapeutic targets in adult ALL.
The existence of an association between infection with hepatitis C virus (HCV) and B-cell non-Hodgkin lymphoma (B-NHL) remains controversial, largely because previous studies were based on prevalent ...case series or comparisons with less than optimal control groups. This hospital-based case-control study was conducted from January 1998 through February 2001 to evaluate the association between HCV infection and B-NHL of different types. Cases were consecutive patients with a new diagnosis of B-NHL; controls were patients from other departments of the same hospitals. Both groups were interviewed using a standardized questionnaire. The prevalence of HCV infection was calculated by histologic type of B-NHL and clinical behavior (indolent or aggressive). Adjusted odds ratio (OR) and HCV-attributable risk (AR) were estimated. HCV prevalence was 17.5% among the 400 lymphoma patients and 5.6% among the 396 controls. The OR of B-NHL (patients vs controls), adjusted by age, sex, level of education, and place of birth, was 3.1 (95% confidence interval CI, 1.8-5.2); an OR indicative of positive association was found for indolent and aggressive B-NHL. The estimated AR was 4.6%. This study confirms an association between HCV and B-NHL. In Italy, 1 of 20 instances of B-NHL may be attributable to HCV infection and may, thus, benefit from antiviral treatment.
