Abstract: Patients with acute myeloblastic leukemia or higher risk myelodysplastic syndromes with 5q deletion (generally within a complex karyotype) respond poorly to intensive chemotherapy and have very poor survival. In this population, we evaluated escalating doses of lenalidomide combined with intensive chemotherapy in a phase II study. Treatment consisted of daunorubicin (45 mg/m2/day, days 1-3 in cohort 1, escalated to 60 mg/m2/day, days 1-3 in cohorts 2 and 3) combined with cytosine arabinoside (200 mg/m2/day, days 1-7) and lenalidomide (10 mg/day, days 1-21 in cohorts 1 and 2, escalated to 25 mg/day, days 1-21 in cohort 3). Eighty-two patients with 5q deletion were enrolled, including 62 with acute myeloblastic leukemia, 62/79 (78%) of whom had a complex karyotype (median 7 cytogenetic abnormalities, all but 2 of them monosomal) and three had unknown karyotypes. Thirty-eight patients (46%) achieved complete remission and the overall response rate was 58.5%. Among the 62 patients with a complex karyotype, 27 achieved complete remission (44%) and 21 had cytogenetic responses. A lower response rate was observed in patients with acute myeloblastic leukemia but other pretreatment factors, including cytogenetic complexity and treatment cohort, did not significantly influence response. Fifteen patients underwent allogeneic stem cell transplantation, including 11 patients in first remission. The 1-year cumulative incidence of relapse was 64.6% and the median overall survival was 8.2 months. By comparison with conventional intensive chemotherapy, the treatment protocol we used appeared to produce higher hematologic and cytogenetic complete remission rates in patients with very poor cytogenetics, but response duration was short in this very poor risk population, highlighting the need for better post-induction strategies. Clinical trial registry number: NCT00885508.

Abstract: International audience; Unlabelled - Gene expression studies have consistently identified a HOXA-overexpressing cluster of T-cell acute lymphoblastic leukemias, but it is unclear whether these constitute a homogeneous clinical entity, and the biological consequences of HOXA overexpression have not been systematically examined. We characterized the biology and outcome of 55 HOXA-positive cases among 209 patients with adult T-cell acute lymphoblastic leukemia uniformly treated during the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003 and -2005 studies. HOXA-positive patients had markedly higher rates of an early thymic precursor-like immunophenotype (40.8% versus 14.5%, P=0.0004), chemoresistance (59.3% versus 40.8%, P=0.026) and positivity for minimal residual disease (48.5% versus 23.5%, P=0.01) than the HOXA-negative group. These differences were due to particularly high frequencies of chemoresistant early thymic precursor-like acute lymphoblastic leukemia in HOXA-positive cases harboring fusion oncoproteins that transactivate HOXA Strikingly, the presence of an early thymic precursor-like immunophenotype was associated with marked outcome differences within the HOXA-positive group (5-year overall survival 31.2% in HOXA-positive early thymic precursor versus 66.7% in HOXA-positive non-early thymic precursor, P=0.03), but not in HOXA-negative cases (5-year overall survival 74.2% in HOXA-negative early thymic precursor versus 57.2% in HOXA-negative non-early thymic precursor, P=0.44). Multivariate analysis further revealed that HOXA positivity independently affected event-free survival (P=0.053) and relapse risk (P=0.039) of chemoresistant T-cell acute lymphoblastic leukemia. These results show that the underlying mechanism of HOXA deregulation dictates the clinico-biological phenotype, and that the negative prognosis of early thymic precursor acute lymphoblastic leukemia is exclusive to HOXA-positive patients, suggesting that early treatment intensification is currently suboptimal for therapeutic rescue of HOXA-positive chemoresistant adult early thymic precursor acute lymphoblastic leukemia. Trial registration - The GRAALL-2003 and -2005 studies were registered at http://www.clinicaltrials.gov as #NCT00222027 and #NCT00327678, respectively.

Abstract: Purpose Acute promyelocytic leukemia (APL) is rare in children. All-trans-retinoic acid (ATRA) combined with chemotherapy, the reference treatment of APL, is generally considered to produce similar results in children and adults. However, previously published childhood APL studies have generally analyzed all patients age < 18 years as a group, without further dividing according to age. Patients and Methods We compared disease characteristics and outcomes of children (age ≤ 12 years), adolescents (13 to 18 years), and adults (> 18 years) included in two multicenter APL clinical trials (APL 93 and 2000 trials). Results Of the 833 patients age ≤ 60 years included in the two trials, 26 (3%), 58 (7%), and 749 (90%) were children, adolescents, and adults, respectively. Children had significantly higher baseline WBC counts (P < .001). The complete remission (CR) rate (92%, 100%, and 94.5%, respectively) and 5-year cumulative incidence of relapse (CIR; 28%, 20%, and 23%, respectively) did not differ between children, adolescents, and adults, whereas adolescents had significantly better overall survival (OS; 5-year OS, 93.6% v 80.4% in adults and 80.4% in children; P = .03). However, in children age ≤ 4 years, the 5-year CIR was 52%, compared with 17.6% in children age 5 to 12 years (P = .006), although most of the younger children who relapsed experienced durable salvage with autologous or allogeneic stem-cell transplantation. Conclusion Adolescents and children age > 4 years with APL treated with ATRA and chemotherapy have outcomes at least as favorable as those of adults. Younger children seem to experience more relapses and may require reinforcement of first-line treatment.

Abstract: Mutations of the CCAAT/enhancer binding protein alpha (CEBPA) gene have been associated with a favorable outcome in patients with acute myeloid leukemia (AML), but mainly in those with a normal karyotype. Here, we analyzed the impact of associated cytogenetic abnormalities or bad-prognosis fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) in 53 patients with CEBPA+ de novo AML treated in the Acute Leukemia French Association trials. We found that only those with a normal karyotype and no FLT3-ITD displayed the expected favorable outcome. In this context, relapse-free, disease-free, and overall survival were significantly longer than in corresponding patients without the CEBPA mutation (P = .035, .016, and .047, respectively). This was not observed in the context of an abnormal karyotype or associated FLT3-ITD. Furthermore, after adjustment on age, trial, and mutation type, these features were independently predictive of shorter overall survival in the subset of patients with CEBPA+ AML (multivariate hazard ratio = 2.7; 95% confidence interval, 1.08-6.7; and 2.9; 95% confidence interval, 1.01-8.2; with P = .034 and .05, for abnormal karyotype and FLT3-ITD, respectively).

Abstract: Purpose This study evaluated the efficacy of pediatric-like acute lymphoblastic leukemia (ALL) therapy in adults with lymphoblastic lymphoma (LL). Patients and Methods This was a prospective phase II study in adults 18 to 59 years old with previously untreated LL. Patients were treated with an adapted pediatric-like ALL protocol, which included a corticosteroid prephase, a five-drug induction reinforced by sequential cyclophosphamide administration, dose-dense consolidation, late intensification, CNS prophylaxis, and a 2-year maintenance phase. Treatment response was assessed by computed tomography and optional positron emission tomography. Allogeneic hematopoietic stem cell transplant was offered to selected patients in first complete remission (CR) or unconfirmed CR. Results The study enrolled 148 patients (131 with T-lineage LL [T-LL] and 17 with B-lineage LL [B-LL]). A total of 119 patients with T-LL (90.8%) and 13 with B-LL (76.5%) reached CR/unconfirmed CR, including 26 with T-LL and two with B-LL who needed a second induction salvage course. Relapse occurred in 34 patients with T-LL and four with B-LL. In patients with T-LL, 3-year event-free survival was 63.3% (95% CI, 54.2% to 71.0%), disease-free survival was 72.4% (95% CI, 63.0% to 79.7%), and overall survival was 69.2% (95% CI, 60.0% to 76.7%). Multivariate analysis identified serum lactate dehydrogenase level and the NOTCH1/FBXW7/RAS/PTEN oncogene (a four-gene oncogenetic classifier) status but not positron emission tomography or hematopoietic stem cell transplant as independent prognostic factors for outcome in T-LL. Conclusion In adults with LL, an intensive pediatric-like ALL treatment protocol was associated with a good response rate and outcome. In patients with T-LL, the four-gene oncogenetic classifier and lactate dehydrogenase level were independent prognostic indicators.

Abstract: Background: ATO is very effective in the treatment of APL and recent results have shown that ATRA+ATO combinations (without CT) were at least as effective as classical ATRA + anthracycline based chemotherapy (CT) while being less myelosuppressive (Lo Coco, NEJM 2014, Burnett, Lancet Oncol, in press). However, access to ATO remains limited for frontline treatment of APL in most countries, which must mainly rely on ATRA+CT combination. In those combinations, investigators have suggested that the amount of CT could be reduced and the incidence of relapses further diminished by introducing ATRA (Sanz) or ATO (Powell) during consolidation cycles. In a randomized trial (APL 2006 trial), we compared for consolidation treatment (after ATRA CT induction treatment) ATO, ATRA and the "classical" Ara C in standard risk APL (ie with baseline WBC < 10G/L). Methods: Between 2006 and 2013 newly diagnosed APL patients (pts) < 70 years with WBC < 10 G/L , after an induction treatment consisting of ATRA 45mg/m2/d until CR with Idarubicin (Ida) 12 mg/m2/dx3 and AraC 200mg/m2/dx7 started on day 3, were randomized for consolidation between AraC, ATO and ATRA. The AraC group ( standard group) received a first consolidation course with, Idarubicin (Ida) 12 mg/m2/dx3 and AraC 200mg/m2/dx7, a second consolidation with Ida 9 mg/m2/dx3 and AraC 1g/m2/12h x4d, and a maintenance during two years with intermittent ATRA 15d/ 3 months and continuous 6 MP + MTX,). The ATO and ATRA groups received the same treatment as the AraC group, but AraC was replaced respectively by ATO 0.15 mg/Kg/d d1 to 25 and ATRA 45 mg/m2/d d1 to 15 for both consolidation courses. We present here results of an analysis made at the reference date January 1st 2014 in the 398 pts aged < 70 years with WBC Results: Among the 398 included pts, 7 were excluded for diagnosis error, 96% achieved CR, 12 (3%) had early death (from bleeding (n=1), sepsis (n=6), Thrombosis (n=4), cardiac arrest (n=1)) and 4 (1%) had resistant leukemia. 353 pts were randomized for consolidation (118, 118 and 117 in the AraC, ATO and ATRA arms, respectively). Pre-treatment characteristics were well balanced between the 3 consolidation groups. Overall, 4, 0, and 7 pts had relapsed (p=0.03) and 6, 5, and 5 pts (p=0.93) had died in CR in the AraC, ATO and ATRA consolidation groups, respectively. Causes of death in CR were sepsis (n=4) and hemorrhage (n=2), AML/MDS (n=5), relapse of a previous cancer (n=2), other (n=2). Two of the 6 deaths in CR related to myelosuppression occurred in each arm. Of the 5 patients who developed AML/MDS, 2, 1 and 2 had been treated in the AraC, ATO and ATRA arms, respectively. Five-year EFS from randomization was 90.8% [85.5; 96.5], 92.5% [87.6; 98.4] and 86.8% [79.7; 94.5] (p=0.52), 5y CIR was 3.89% [0.08 ; 7.69], 0% [0 ; 0], 7.41% [1.96 ; 12.87] (p=0.03) and 5 year OS was 93.6% [89.1; 98.3]%, 92.8% [87.6; 98.4]% and 91.9% [85.4; 98.9] (p=NS), in the AraC, ATO and ATRA consolidation groups, respectively. Median time to ANC >1 G/L after the first consolidation course was 24, 24 and 17 in the AraC, ATO and ATRA group, respectively (AraC vs ATO: p= 0.96; ATO vs ATRA: p1 G/L after the second consolidation course was 23, 19 and 13 days (AraC vs ATO: p= 0.02; ATO vs ATRA: p Median duration of hospitalization after the first and the second consolidation course were 32d, 29d, 32d (p= NS) and 30d, 17d, 15d in the AraC, ATO and ATRA group, respectively (p Conclusion: Very high CR rates are now obtained in standard risk APL on a very large multicenter basis using classical ATRA and anthracycline based CT combinations, with very few relapses. On the other hand, our results strongly suggest that relapse rates observed with regimens without ATO, although they are low, can be significantly further reduced by addition of ATO. The Ida-ATRA consolidation regimen in particular, while carrying reduced toxicity, was associated with a relapse rate of 7.4%. Our results therefore advocate systematic introduction of ATO in the first line treatment of standard risk APL, but probably not concomitantly with CT, a situation where we found myelosuppression to be significant.

Abstract: Introduction: Gene expression studies have consistently identified a HOXA positive (HOXAPos) subgroup of T-cell acute lymphoblastic leukemia (T-ALL) (Ferrando et al, Cancer Cell 2002, Soulier et al, Blood 2005, Homminga et al, Cancer Cell 2011). It is however unclear if HOXAPos T-ALL constitutes a distinct and homogeneous clinical entity, and the biological consequences of HOXA over-expression have not been systematically examined. Methods: We identified and characterized the biological characteristics and clinical outcome of 55 HOXAPos cases among a cohort of 209 adult T-ALL patients who were uniformly treated as part of the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003 and -2005 studies. Results: HOXAPos patients had higher rates of an early thymic precursor (ETP)-like immunophenotype (38% v 13.9%, p = 0.0008), early bone marrow chemoresistance (59.3% v 40.8%, p = 0.026) and positive minimal residual disease (MRD, 51.5% v 23.5%, p = 0.01) than the HOXANeg group. These differences were due to a particularly high frequency of chemoresistant ETP-ALL among HOXAPos cases harboring leukemic fusion proteins that trans-activate the HOXA locus (e.g. PICALM-MLLT10, SET-NUP214). Strikingly, the presence of an ETP-like immunophenotype conferred marked differences in outcome within the HOXAPos group (5 year event-free survival (EFS) 25% for HOXAPos ETP v 52.2% for HOXAPos non-ETP, p = 0.02), which were mirrored by corresponding increases in cumulative incidence of relapse (CIR, 57.1% v 25%, p = 0.01, Figure 1). In contrast, these survival differences were not seen in the HOXANeg patients, where ETP and non-ETP cases had similar 5 year EFS (54.9% v 50%, p = 0.73) and CIR (34.5% v 41.2%, p = 0.57). Multivariate analysis revealed that early bone marrow chemosensitivity was the clinico-biological covariate that had the strongest prognostic interaction with HOXA status. HOXA positivity conferred significant decreases in both the EFS and CIR of chemoresistant patients (p = 0.053 and 0.039 respectively), that was independent of white blood cell count (WCC), stem cell transplant (SCT), ETP phenotype, EGIL classification, and our recently reported risk classifier that integrates the prognostic effects of mutations of NOTCH1, FBXW7, RAS and PTEN (Trinquand et al, J Clin Oncol 2013). There were corresponding marked survival differences within the HOXAPos cohort between chemoresistant and chemosensitive cases. These disparities were not seen in the HOXANeg group, indicating that the prognostic value of chemosensitivity in adult T-ALL is specific to HOXAPos patients. Discussion: Our data show that clinico-biological phenotype is intimately linked to the underlying mechanism of HOXA locus deregulation, and we identify HOXA overexpression as a novel prognostic variable in ETP-ALL. Multivariate analysis suggests that this poor outcome is strongly related to intrinsic treatment resistance, and that this effect is exclusive to the HOXAPos cohort. Patients in the GRAALL-2003 and -2005 studies received enhanced induction and/ or salvage therapy in the event of poor early treatment response. Our results suggest that pediatric regimen-based intensification provides significant survival benefits for HOXANeg chemoresistant cases. In contrast, these modifications are inadequate for therapeutic rescue of the majority of HOXAPos chemoresistant ETP-ALL. The dramatically inferior prognosis of this group mandates consideration for alternative treatments in future clinical trials. Figure 1. Figure 1.

Abstract: International audience; Background - Reports of patients with secondary acute promyelocytic leukemia (APL) have increased in recent years, particularly for those who received treatment with mitoxantrone, and retrospective studies have suggested that their characteristics and outcomes were similar to those of patients with de novo APL.Methods - The authors investigated patients with de novo and secondary APL who were included in the ongoing APL-2006 trial. Patients with secondary APL who were included in that trial also were compared with a previous retrospective cohort of patients with secondary APL.Results - In the APL-2006 trial, 42 of 280 patients (15%) had secondary APL. Compared with the retrospective cohort, patients with secondary APL in the APL-2006 trial had a lower incidence of prior breast carcinoma (35.7% vs 57%; P = .03) and a higher incidence of prior prostate carcinoma (26.2% vs 4.7%; P Conclusions - Although the incidence of secondary APL appears to be stable over time, evolving strategies for the treatment of primary cancers have reduced its occurrence among breast cancer patients but have increased its incidence among patients with prostate cancer. The current results confirm prospectively that patients with secondary APL have characteristics and outcomes similar to those of patients with de novo APL.

Abstract: T-cell acute lymphoblastic leukaemias (T-ALL) are aggressive malignant proliferations characterized by high relapse rates and great genetic heterogeneity. TAL1 is amongst the most frequently deregulated oncogenes. Yet, over half of the TAL1+ cases lack TAL1 lesions, suggesting unrecognized (epi)genetic deregulation mechanisms. Here we show that TAL1 is normally silenced in the T-cell lineage, and that the polycomb H3K27me3-repressive mark is focally diminished in TAL1+ T-ALLs. Sequencing reveals that >20% of monoallelic TAL1+ patients without previously known alterations display microinsertions or RAG1/2-mediated episomal reintegration in a single site 5′ to TAL1. Using ‘allelic-ChIP’ and CrispR assays, we demonstrate that such insertions induce a selective switch from H3K27me3 to H3K27ac at the inserted but not the germline allele. We also show that, despite a considerable mechanistic diversity, the mode of oncogenic TAL1 activation, rather than expression levels, impact on clinical outcome. Altogether, these studies establish site-specific epigenetic desilencing as a mechanism of oncogenic activation., TAL1 is frequently deregulated in T-cell acute lymphoblastic leukaemias, but the mechanism remains largely unclear. Here the authors show that microinsertions upstream of TAL1 cause its epigenetic reactivation, and that the mode of TAL1 activation correlates with prognosis.

Abstract: International audience; Central nervous system (CNS) thrombotic events are a well-known complication of acute lymphoblastic leukemia (ALL) induction therapy, especially with treatments including l-asparaginase (l-ASP). Data on risk factors and clinical evolution is still lacking in adult patients. We report on the clinical evolution of 22 CNS venous thrombosis cases occurring in 708 adults treated for ALL or lymphoblastic lymphoma (LL) with the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-induction protocol, which included eight L-ASP (6,000 IU/m2) infusions. The prevalence of CNS thrombosis was 3.1%. CNS thrombosis occurred after a median of 18 days (range: 11–31) when patients had received a median of three l-ASP injections (range: 2–7). Patients with CNS thrombosis exhibited a median antithrombin (AT) nadir of 47.5% (range: 36–67%) at Day 17 (range: D3–D28), and 95% of them exhibited AT levels lower than 60%. There were no evident increase in hereditary thrombotic risk factors prevalence, and thrombosis occurred despite heparin prophylaxis which was performed in 90% of patients. Acquired AT deficiency was frequently detected in patients with l-ASP-based therapy, and patients with CNS thrombosis received AT prophylaxis (45%) less frequently than patients without CNS thrombosis (83%), P = 0.0002). CNS thrombosis was lethal in 5% of patients, while 20% had persistent sequelae. One patient received all planned l-ASP infusions without recurrence of CNS thrombotic whereas l-ASP injections were discontinued in 20 patients during the management of thrombosis without a significant impact on overall survival (P = 0.4).

Abstract: International audience; PURPOSE: The GRASPALL/GRAALL-SA2-2008 Phase II trial evaluated the safety and efficacy of L-asparaginase encapsulated within erythrocytes (GRASPA®) in patients ≥ 55 years with Philadelphia chromosome-negative acute lymphoblastic leukemia. FINDINGS: Thirty patients received escalating doses of GRASPA® on Day 3 and 6 of induction Phases 1 and 2. The primary efficacy endpoint was asparagine depletion \textless 2 µmol/L for at least 7 days. This was reached in 85 and 71% of patients with 100 and 150 IU/kg respectively but not with 50 IU/kg. Grade 3/4 infection, hypertransaminasemia, hyperbilirubinemia and deep vein thrombosis occurred in 77, 20, 7, and 7% of patients, respectively. No allergic reaction or clinical pancreatitis was observed despite 17% of Grade 3/4 lipase elevation. Anti-asparaginase antibodies were detected in 50% of patients and related to a reduction in the duration of asparagine depletion during induction Phase 2 without decrease of encapsulated L-asparaginase activity. Complete remission rate was 70%. With a median follow-up of 42 months, median overall survival was 15.8 and 9.7 months, in the 100 and 150 IU/kg cohorts respectively. CONCLUSIONS: The addition of GRASPA®, especially at the 100 IU/kg dose level, is feasible in elderly patients without excessive toxicity and associated with durable asparagine depletion.

Abstract: MTCP1 (for Mature-T-Cell Proliferation) is the first gene unequivocally identified in the group of uncommon leukemias with a mature phenotype. The three-dimensional solution structure of the human p8(MTCP1) protein encoded by the MTCP1 oncogene was determined by homonuclear proton two-dimensional NMR methods at 600 MHz. After sequence specific assignments, a total of 931 distance restraints and 57 dihedral restraints were collected. The location of the three previously unassigned disulfide bridges was determined from preliminary DIANA structures, using a statistical analysis of intercystinyl distances. The solution structure of p8(MTCP1) is presented as a set of 30 DIANA structures, further refined by restrained molecular dynamics using a simulated annealing protocol with the AMBER force field. The r.m.s.d. values with respect to the mean structure for the backbone and all heavy atoms for a family of 30 structures are 0.73(+/-0.28) and 1.17(+/-0.23) A, when the structured core of the protein (residues 5 to 63) is considered. The solution structure of p8(MTCP1) reveals an original scaffold consisting of three alpha helices, associated with a new cysteine motif. Two of the helices are covalently paired by two disulfide bridges, forming an alpha-hairpin which resembles an antiparallel coiled-coil. The third helix is oriented roughly parallel to the plane defined by the alpha-antiparallel motif and its axis forms an angle of approximately 60 degrees with respect to the main axis of this motif.

Abstract: Purpose The Group for Research in Adult Acute Lymphoblastic Leukemia (GRAALL) recently reported a significantly better outcome in T-cell acute lymphoblastic leukemia (T-ALL) harboring NOTCH1 and/or FBXW7 (N/F) mutations compared with unmutated T-ALL. Despite this, one third of patients with N/F-mutated T-ALL experienced relapse. Patients and Methods In a series of 212 adult T-ALLs included in the multicenter randomized GRAALL-2003 and -2005 trials, we searched for additional N/K-RAS mutations and PTEN defects (mutations and gene deletion). Results N/F mutations were identified in 143 (67%) of 212 patients, and lack of N/F mutation was confirmed to be associated with a poor prognosis. K-RAS, N-RAS, and PTEN mutations/deletions were identified in three (1.6%) of 191, 17 (8.9%) of 191, and 21 (12%) of 175 patients, respectively. The favorable prognostic significance of N/F mutations was restricted to patients without RAS/PTEN abnormalities. These observations led us to propose a new T-ALL oncogenetic classifier defining low-risk patients as those with N/F mutation but no RAS/PTEN mutation (97 of 189 patients; 51%) and all other patients (49%; including 13% with N/F and RAS/PTEN mutations) as high-risk patients. In multivariable analysis, this oncogenetic classifier remained the only significant prognostic covariate (event-free survival: hazard ratio [HR], 3.2; 95% CI, 1.9 to 5.15; P < .001; and overall survival: HR, 3.2; 95% CI, 1.9 to 5.6; P < .001). Conclusion These data demonstrate that the presence of N/F mutations in the absence of RAS or PTEN abnormalities predicts good outcome in almost 50% of adult T-ALL. Conversely, the absence of N/F or presence of RAS/PTEN alterations identifies the remaining cohort of patients with poor prognosis.

Abstract: CALM-AF10 (also known as PICALM-MLLT10) is the commonest fusion protein in T-cell acute lymphoblastic leukemia, but its prognostic impact remains unclear. Molecular screening at diagnosis identified CALM-AF10 in 30/431 (7%) patients with T-cell acute lymphoblastic leukemia aged 16 years and over and in 15/234 (6%) of those aged up to 15 years. Adult CALM-AF10-positive patients were predominantly (72%) negative for surface (s)CD3/T-cell receptor, whereas children were predominantly (67%) positive for T-cell receptor. Among 22 adult CALM-AF10-positive patients treated according to the LALA94/GRAALL03-05 protocols, the poor prognosis for event-free survival (P=0.0017) and overall survival (P=0.0014) was restricted to the 15 T-cell receptor-negative cases. Among CALM-AF10-positive, T-cell receptor-negative patients, 82% had an early T-cell precursor phenotype, reported to be of poor prognosis in pediatric T-cell acute lymphoblastic leukemia. Early T-cell precursor acute lymphoblastic leukemia corresponded to 22% of adult LALA94/GRAALL03-05 T-cell acute lymphoblastic leukemias, but had no prognostic impact per se. CALM-AF10 fusion within early T-cell precursor acute lymphoblastic leukemia (21%) did, however, identify a group with a poor prognosis with regards to event-free survival (P=0.04). CALM-AF10 therefore identifies a poor prognostic group within sCD3/T-cell receptor negative adult T-cell acute lymphoblastic leukemias and is over-represented within early T-cell precursor acute lymphoblastic leukemias, in which it identifies patients in whom treatment is likely to fail. Its prognosis and overlap with early T-cell precursor acute lymphoblastic leukemia in pediatric T-cell acute lymphoblastic leukemia merits analysis. The clinical trial GRAALL was registered at Clinical Trials.gov number NCT00327678.

Abstract: International audience; We report here the results of the GRAAPH-2003 trial with long-term follow-up in 45 patients with de novo Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). Imatinib-based strategy improved the 4-year overall survival (OS) up to 52% versus 20% in the pre-imatinib LALA-94 trial (P = .0001). Despite the selection in patients who actually underwent transplantation, these results suggest that allogeneic or autologous stem cell transplants (SCTs) still have a place in overcoming the poor prognosis of Ph+ ALL in the era of imatinib therapy. OS was 50% after allogeneic SCT (24 patients), 33% in patients without a transplantation (9 patients), and 80% after autologous SCT (10 patients without allogeneic donor or >55 years, including 7 patients in complete molecular response).

Abstract: International audience; Infections are a major complication in patients with acute myeloid leukemia undergoing intensive chemotherapy. They remain a major cause of therapy-associated morbidity and mortality, and represent a frequent cause of treatment withdrawal. An analysis of the medical charts of 459 younger adults included in the multicenter Acute Leukemia French Association (ALFA)-9802 trial showed that 1369 febrile episodes occurred among the 459 registered patients, including fever without identifiable source (23%) and clinically or microbiologically documented infections (77%). Bloodstream infections occurred in 314 episodes, including 129 documented episodes with Gram-positive and 96 with Gram-negative pathogens. Pulmonary infection was diagnosed in 144/1054 documented infectious episodes (14%). Invasive fungal infection was probable or proven in 116 patients. In all, 15 patients died of infection-associated complications, of whom seven died during early induction therapy, one during salvage therapy and seven during consolidation therapy. Better supportive care strategies may improve overall survival in patients undergoing chemotherapy for acute myeloid leukemia.

Abstract: International audience; BACKGROUND: The results of the addition of gemtuzumab ozogamicin, an anti-CD33 antibody conjugate, to the standard treatment for patients with acute myeloid leukaemia in phase 3 trials were contradictory. We investigated whether the addition of low fractionated-dose gemtuzumab ozogamicin to standard front-line chemotherapy would improve the outcome of patients with this leukaemia without causing excessive toxicity. METHODS: In a phase 3, open-label study, undertaken in 26 haematology centres in France, patients aged 50-70 years with previously untreated de novo acute myeloid leukaemia were randomly assigned with a computer-generated sequence in a 1:1 ratio with block sizes of four to standard treatment (control group) with or without five doses of intravenous gemtuzumab ozogamicin (3 mg/m(2) on days 1, 4, and 7 during induction and day 1 of each of the two consolidation chemotherapy courses). The primary endpoint was event-free survival (EFS). Secondary endpoints were relapse-free (RFS), overall survival (OS), and safety. Analysis was by intention to treat. This study is registered with EudraCT, number 2007-002933-36. FINDINGS: 280 patients were randomly assigned to the control (n=140) and gemtuzumab ozogamicin groups (n=140), and 139 patients were analysed in each group. Complete response with or without incomplete platelet recovery to induction was 104 (75%) in the control group and 113 (81%) in the gemtuzumab ozogamicin group (odds ratio 1*46, 95% CI 0*20-2*59; p=0*25). At 2 years, EFS was estimated as 17*1% (10*8-27*1) in the control group versus 40*8% (32*8-50*8) in the gemtuzumab ozogamicin group (hazard ratio 0*58, 0*43-0*78; p=0*0003), OS 41*9% (33*1-53*1) versus 53*2% (44*6-63*5), respectively (0*69, 0*49-0*98; p=0*0368), and RFS 22*7% (14*5-35*7) versus 50*3% (41*0-61*6), respectively (0*52, 0*36-0*75; p=0*0003). Haematological toxicity, particularly persistent thrombocytopenia, was more common in the gemtuzumab ozogamicin group than in the control group (22 [16%] vs 4 [3%]; p

Abstract: Despite recent progress in the understanding of acute lymphoblastic leukemia (T-ALL) oncogenesis, few markers are sufficiently frequent in large subgroups to allow their use in therapeutic stratification. Low ERG and BAALC expression (E/Blow) and NOTCH1/FBXW7 (N/F) mutations have been proposed as powerful prognostic markers in large cohorts of adult T-ALL. We therefore compared the predictive prognostic value of N/F mutations versus E/Blow in 232 adult T-ALLs enrolled in the LALA-94 and Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL) protocols. The outcome of T-ALLs treated in the pediatric-inspired GRAALL trials was significantly superior to the LALA-94 trial. Overall, 43% and 69% of adult T-ALL patients were classified as E/Blow and N/F mutated, respectively. Strikingly, the good prognosis of N/F mutated patients was stronger in more intensively treated, pediatric-inspired GRAALL patients. The E/B expression level did not influence the prognosis in any subgroup. N/F mutation status and the GRAALL trial were the only 2 independent factors that correlated with longer overall survival by multivariate analysis. This study demonstrates that the N/F mutational status and treatment protocol are major outcome determinants for adults with T-ALL, the benefit of pediatric inspired protocols being essentially restricted to the N/F mutated subgroup.

Abstract: International audience; l-asparaginase encapsulated within erythrocytes (GRASPA(®) ) should allow serum asparagine depletion over a longer period than the native form of the enzyme, using lower doses and allowing better tolerance. The GRASPALL 2005-01 study, a multicentre randomized controlled trial, investigated three doses of GRASPA(®) for the duration of asparagine depletion in a phase I/II study in adults and children with acute lymphoblastic leukaemia (ALL) in first relapse. Between February 2006 and April 2008, 18 patients received GRASPA(®) (50 iu/kg: n = 6,100 iu/kg: n = 6, 150 iu/kg: n = 6) after randomization, and six patients were assigned to the Escherichia coli native l-asparaginase (E. colil-ASNase) control group. GRASPA(®) was effective at depleting l-asparagine. One single injection of 150 iu/kg of GRASPA(®) provided similar results to 8 × 10,000 iu/m(2) intravenous injections of E. colil-ASNase. The safety profile of GRASPA(®) showed a reduction in the number and severity of allergic reactions and a trend towards less coagulation disorders. Other expected adverse events were comparable to those observed with E. colil-ASNase and there was also no difference between the three doses of GRASPA(®) .

Abstract: International audience; BACKGROUND: The prognosis of acute lymphoblastic leukemia in the elderly is poor. The GRAALL-SA1 phase II, randomized trial compared the efficacy and toxicity of pegylated liposomal doxorubicin versus continuous-infusion doxorubicin in patients 55 years or older with Philadelphia chromosome-negative acute lymphoblastic leukemia. DESIGN AND METHODS: Sixty patients received either continuous-infusion doxorubicin (12 mg/m(2)/day) and continuous-infusion vincristine (0.4 mg/day) on days 1-4 or pegylated liposomal doxorubicin (40 mg/m(2)) and standard vincristine (2 mg) on day 1, accompanied by dexamethasone, followed at day 28 by a second cycle, reinforced by cyclophosphamide. End-points were safety, outcome and prognostic factors. RESULTS: Myelosuppression was reduced in the pegylated liposomal doxorubicin arm with shorter severe neutropenia (P=0.05), shorter severe thrombocytopenia (P=0.03), and fewer red blood cell transfusions (P=0.04). Grade 3/4 infections and Gram-negative bacteremia were reduced in the pegylated liposomal doxorubicin arm (P=0.04 and P=0.02, respectively). There was a trend towards fewer cardiac events among the patients who received pegylated liposomal doxorubicin (1/29 versus 6/31). The complete remission rate was 82% and, with a median follow-up of 4 years, median event-free survival and overall survival were 9 and 10 months, respectively. Despite the better tolerance of pegylated liposomal doxorubicin, no differences in survival were observed between the two arms, due to trends towards more induction refractoriness (17 versus 3%, P=0.10) and a higher cumulative incidence of relapse (52% versus 32% at 2 years, P=0.20) in the pegylated liposomal doxorubicin arm. CONCLUSIONS: With the drug schedules used in this study, pegylated liposomal doxorubicin did not improve the outcome of elderly patients with acute lymphoblastic leukemia despite reduced toxicities.

Abstract: Purpose In patients with acute myeloid leukemia (AML), induction chemotherapy is based on standard doses of anthracyclines and cytarabine. High doses of cytarabine have been reported as being too toxic for patients older than age 50 years, but few studies have evaluated intensified doses of anthracyclines. Patients and Methods In this randomized Acute Leukemia French Association 9801 (ALFA-9801) study, high doses of daunorubicin (DNR; 80 mg/m2/d × 3 days) or idarubicin (IDA4; 12 mg/m2/d × 4 days) were compared with standard doses of idarubicin (IDA3; 12 mg/m2/d × 3 days) for remission induction in patients age 50 to 70 years, with an event-free survival (EFS) end point. After two consolidation courses based on intermediate doses of cytarabine, patients in continuous remission were randomly assigned to receive or not receive maintenance therapy with recombinant interleukin-2 (rIL-2; 5 × 106 U/m2 × 5 days each month) for a total duration of 12 months. A total of 468 patients entered the study (median age, 60 years). Results Overall complete remission rate was 77% with significant differences among the three randomization arms (83%, 78%, and 70% in the IDA3, IDA4, and DNR arms, respectively; P = .04). However, no significant differences were observed in relapse incidence, EFS, or overall survival among the three arms. In the 161 patients randomly assigned for maintenance therapy, no difference in outcome was observed between the rIL-2 and the no further treatment arms. Conclusion Neither intensification of anthracycline doses nor maintenance with rIL-2 showed a significant impact on AML course, at least as scheduled in this trial.

Abstract: Acute promyelocytic leukemia (APL) is highly curable with the combination of all-trans retinoic acid (ATRA) and anthracycline-based chemotherapy (CT), but very long-term results of this treatment, when CT should be added to ATRA and the role of maintenance treatment, remain uncertain. In our APL93 trial that included 576 newly diagnosed APL patients, with a median follow-up of 10 years, 10-year survival was 77%. Maintenance treatment significantly reduced 10-year cumulative incidence of relapses, from 43.2% to 33%, 23.4%, and 13.4% with no maintenance, maintenance using intermittent ATRA, continuous 6 mercaptopurine plus methotrexate, and both treatments, respectively (P < .001). Maintenance particularly benefited patients with white blood cell (WBC) count higher than 5 × 109/L (5000/μL). Early addition of CT to ATRA significantly improved 10-year event-free survival (EFS), but without significant effect on overall survival (OS). The 10-year cumulative incidence of deaths in complete response (CR), resulting mainly from myelosuppression, was 5.7%, 15.4%, and 21.7% in patients younger than 55, 55 to 65, and older than 65 years, respectively, supporting the need for less myelosuppressive treatments, particularly for consolidation therapy. This study is registered at http://clinicaltrials.gov as NCT00599937.

Abstract: This phase 3, multicenter, open-label study evaluated the efficacy and safety of tipifarnib compared with best supportive care (BSC), including hydroxyurea, as first-line therapy in elderly patients (≥70 years) with newly diagnosed, de novo, or secondary acute myeloid leukemia. A total of 457 patients were enrolled with 24% 80 years of age or older. Tipifarnib 600 mg orally twice a day was administered for the first 21 consecutive days, in 28-day cycles. The primary endpoint was overall survival. The median survival was 107 days for the tipifarnib arm and 109 days for the BSC arm. The hazard ratio (tipifarnib vs BSC) for overall survival was 1.02 (P value by stratified log-rank test, .843). The complete response rate for tipifarnib in this study (8%) was lower than that observed previously, but with a similar median duration of 8 months. The most frequent grade 3 or 4 adverse events were cytopenias in both arms, slightly more infections (39% vs 33%), and febrile neutropenia (16% vs 10%) seen in the tipifarnib arm. The results of this randomized study showed that tipifarnib treatment did not result in an increased survival compared with BSC, including hydroxyurea. This trial was registered at www.clinicaltrials.gov as #NCT00093990.

Abstract: International audience; BACKGROUND: There is a need for standardization of treatment decisions in older patients with acute myeloid leukemia. The aim of the present study was to analyze the decisional value of poor risk factors in 416 elderly patients treated in the ALFA-9803 trial in order to derive a decisional index. DESIGN AND METHODS: Standard multivariate analysis was used to identify risk factors for overall survival. Risk factors were then considered as good decision tools if associated with a frequency >10% and a false positive rate or =75 years, performance status > or =2, and white cell count > or =50 x 10(9)/L. This simple two-class decisional index, which was validated in an independent patient set, enabled us to discriminate 100 patients (24%) who had an estimated overall survival of only 19% at 12 months, with a good 9% false positive rate. CONCLUSIONS: We propose waiting for cytogenetic information before making treatment decisions in elderly patients with acute myeloid leukemia. Those patients with unfavorable cytogenetics, as well as patients with at least two of the following features, age > or =75 years, performance status > or =2, and white cell count > or =50 x 10(9)/L, should not be considered for standard intensive chemotherapy (ClinicalTrials.gov identifier: NCT00363025).

Abstract: In elderly patients with acute myeloid leukemia (AML) treated intensively, no best postremission strategy has emerged yet. This clinical trial enrolled 416 patients with AML aged 65 years or older who were considered eligible for standard intensive chemotherapy, with a first randomization comparing idarubicin with daunorubicin for all treatment sequences. After induction, an ambulatory postremission strategy based on 6 consolidation cycles administered monthly in outpatients was randomly compared with an intensive strategy with a single intensive consolidation course similar to induction. Complete remission (CR) rate was 57% with 10% induction deaths, and estimated overall survival was 27% at 2 years and 12% at 4 years, without notable differences between anthracycline arms. Among the 236 patients who reached CR, 164 (69%) were randomized for the postremission comparison. In these patients, the multivariate odds ratio in favor of the ambulatory arm was 1.51 for disease-free survival (P =.05) and 1.59 for overall survival from CR (P =.04). Despite repeated courses of chemotherapy associated with a longer time under treatment, the ambulatory arm was associated with significantly shorter rehospitalization duration and lower red blood cell unit and platelet transfusion requirements than observed in the intensive arm. In conclusion, more prolonged ambulatory treatment should be preferred to intensive chemotherapy as postremission therapy in elderly patients with AML reaching CR after standard intensive remission induction.

Abstract: The identification of protein components in complex networks of co-regulators responsible for the modulation of proliferation versus differentiation modes of cell growth is a major problem. We use a combination of surface enhanced laser desorption/ionization mass spectrometry, surface plasmon resonance coupled to electrospray mass spectrometry, and immunoelectromobility shift assays to identify members of the MAX/MAD family binding to a specific DNA silencer fragment involved in the regulation of transcription for the human T-cell receptor Vbeta2.2 segment. We also identify the cofactors mSin3 and N-CoR known to interact with histone deacetylases. Inhibition of deacetylase activity in Jurkat cells prevented transcription inhibitor complex formation at the Vbeta2.2 segment, suggesting that this is either directly or indirectly dependent on the presence of HDACs.

Abstract: International audience; The human oncoprotein p13 MTCP1 is coded by the MTCP1 gene, a gene involved in chromosomal translocations associated with T-cell prolymphocytic leukemia, a rare form of human leukemia with a mature T-cell phenotype. The primary sequence of p13 MTCP1 is highly and only homologous to that of p14 TCL1 , a product coded by the gene TCL1 which is also involved in T-cell prolymphocytic leukemia. These two proteins probably represent the first members of a new family of oncogenic proteins. We present the three-dimensional solution structure of the recombinant p13 MTCP1 determined by homonuclear proton two-dimensional NMR methods at 600 MHz. After proton resonance assignments, a total of 1253 distance restraints and 64 dihedral restraints were collected. The solution structure of p13 MTCP1 is presented as a set of 20 DYANA structures. The rmsd values with respect to the mean structure for the backbone and all heavy atoms for the conformer family are 1.07 ± 0.19 and 1.71 ± 0.17 Å, when the structured core of the protein (residues 11-103) is considered. The solution structure of p13 MTCP1 consists of an orthogonal β-barrel, composed of eight antiparallel β-strands which present an original arrangement. The two β-pleated loops which emerge from this barrel might constitute the interaction surface with a potential molecular partner.

29. HOXA genes are included in genetic and biologic networks defining human acute T-cell leukemia (T-ALL).

Abstract: Using a combination of molecular cytogenetic and large-scale expression analysis in human T-cell acute lymphoblastic leukemias (T-ALLs), we identified and characterized a new recurrent chromosomal translocation, targeting the major homeobox gene cluster HOXA and the TCRB locus. Real-time quantitative polymerase chain reaction (RQ-PCR) analysis showed that the expression of the whole HOXA gene cluster was dramatically dysregulated in the HOXA-rearranged cases, and also in MLL and CALM-AF10-related T-ALL cases, strongly suggesting that HOXA genes are oncogenic in these leukemias. Inclusion of HOXA-translocated cases in a general molecular portrait of 92 T-ALLs based on large-scale expression analysis shows that this rearrangement defines a new homogeneous subgroup, which shares common biologic networks with the TLX1- and TLX3-related cases. Because T-ALLs derive from T-cell progenitors, expression profiles of the distinct T-ALL subgroups were analyzed with respect to those of normal human thymic subpopulations. Inappropriate use or perturbation of specific molecular networks involved in thymic differentiation was detected. Moreover, we found a significant association between T-ALL oncogenic subgroups and ectopic expression of a limited set of genes, including several developmental genes, namely HOXA, TLX1, TLX3, NKX3-1, SIX6, and TFAP2C. These data strongly support the view that the abnormal expression of developmental genes, including the prototypical homeobox genes HOXA, is critical in T-ALL oncogenesis.
