Purpose The treatment of acute myeloid leukemia (AML) in first relapse is associated with unsatisfactory rates of complete responses that usually are short lived. Therefore, a clinically useful prognostic index can facilitate therapeutic decision making and evaluation of investigational treatment strategies at relapse of AML. Patients and Methods A prognostic score is presented based on the multivariate analysis of 667 AML patients in first relapse among 1,540 newly diagnosed non-M3 AML patients (age 15 to 60 years) entered onto three successive Dutch-Belgian Hemato-Oncology Cooperative Group and the Swiss Group for Clinical Cancer Research Collaborative Group trials. Results Four clinically relevant parameters are included in this index (ie, length of relapse-free interval after first complete remission, cytogenetics at diagnosis, age at relapse, and whether previous stem-cell transplantation was performed). Using this stratification system, three risk groups were defined: a favorable prognostic group A (overall survival [OS] of 70% at 1 year and 46% at 5 years), an intermediate-risk group B (OS of 49% at 1 year and 18% at 5 years), and a poor-risk group C (OS of 16% at 1 year and 4% at 5 years). Conclusion The prognostic index estimates the outcome of AML patients in first relapse using four commonly applied clinical parameters and might identify patients who are candidates for salvage and investigational therapy.

Abstract The treatment of acute myeloid leukemia (AML) in first relapse is associated with unsatisfactory rates of complete responses that are usually short lived. Previously proposed prognostic classification methods serving therapeutic decisions and evaluation of investigational treatment strategies at relapse of AML have been based on the duration of the relapse free interval and have largely neglected the influence of other known prognostic factors. Here we present an improved clinically useful prognostic index. This index has been developed from a multivariate analysis of 667 AML patients in first relapse among 1540 newly diagnosed non-M3 AML patients of age 15 to 60 years entered into three successive HOVON/SAKK Collaborative Group trials. The score, which has a range of 0 to 14 points, uses four relevant parameters. The parameters are: length of relapse free interval after first complete remission (more than 18 months: 0 points; 7 to 18 months: 3 points; 6 months or less: 5 points), cytogenetics at diagnosis (t(16;16) or inv(16): 0 points; t(8;21): 3 points; other cytogenetics: 5 points), age at relapse (35 years or younger: 0 points; 36 to 45 years: 1 point; older than 45 years: 2 points) and whether or not a previous stem cell transplantation (SCT) has been undertaken in first complete remission (no SCT: 0 points; previous SCT: 2 points). These points were assigned following estimations of the relative values of each of these factors contributing to outcome. Ultimately, three risk groups were defined: a favorable prognostic group A (0 to 6 points; overall survival of 70% at one year and 46% at five years), an intermediate risk group B (7 to 9 points; overall survival of 49% at one year and 18% at five years), and an unfavorable risk group C (10 to 14 points; overall survival of 16% at one year and 4% at five years). Thus, four commonly applied clinical parameters may identify among patients with AML in first relapse those for salvage or investigational therapy.

Abstract The treatment of older adults with acute myeloid leukemia (AML) is associated with unsatisfactory rates of complete responses and long-term overall survival. Therefore, a clinically usefull prognostic index can facilitate therapeutic decision making and evaluation of investigational treatment strategies in this patient population. Overall, 243 of the 432 patients (56%, 95% CI: 51–60%) achieved CR (229 of them after the first induction course and 14 after salvage therapy). The median disease-free survival (DFS) and the median overall survival (OS) of the entire cohort were 8.4 months (95% CI: 7.2–10.1 months) and 8.3 months (95% CI: 7.2–10 months) respectively. A prognostic score is presented based on the multivariate analysis of 432 newly diagnosed non-M3 AML patients aged more than 60 years, selected on the base of their initial performance status and the absence of severe co-morbidity factors, for entering onto five successive clinical trials combining an anthracycline and cytarabine. Four clinically relevant parameters are included in this index: cytogenetics at diagnosis, history of previous hematologic disorder, hematologic features at diagnosis, and LDH level at diagnosis. Using this stratification system, three risk groups were defined: a favorable-risk group A (OS of 39% at 2 years and 21% at 5 years), an intermediate-risk group B (OS of 19% at 2 years and 8% at 5 years), and a poor-risk group (OS of 5% at 2 years and 0% at 5 years). The prognostic index estimates the outcome of elderly AML patients usually selected for intensive chemotherapy trials using four easily determined parameters and might identify patients who are really candidates for this treatment strategy from those for whom investigational therapy or palliation may be most appropriate.

Abstract Background Acute myeloid leukemia (AML) is a complex disease caused by various genetic alterations. Some prognosis-associated cytogenetic aberrations or gene mutations such as FLT3-internal tandem duplication (ITD), t(8;21)(q22;q22)/RUNX1-RUNX1T1, and inv(16)(p13q22)/CBFB-MYH11 have been found and used to stratify the risk. Numerous gene mutations have been implicated in the pathogenesis of AML, including mutations of DNMT3A, IDH1/2, TET2 and EZH2 in addition to RAS, KIT, NPM1, CEBPA and FLT3in the recent development of massively parallel sequencing technologies. However, even after incorporating these molecular markers, the prognosis is unclear in a subset of AML patients. Recently, NUP98-NSD1 fusion gene was identified as a poor prognostic factor for AML. We have reported that all pediatric AML patients with NUP98-NSD1 fusion showed high expression of the PR domain containing 16 (PRDM16; also known as MEL1) gene, which is a zinc finger transcription factor located near the breakpoint at 1p36. PRDM16 is highly homologous to MDS1/EVI1, which is an alternatively spliced transcript of EVI1. Furthermore, PRDM16 is essential for hematopoietic stem cell maintenance and remarkable as a candidate gene to induce leukemogenesis. Recent reports revealed that high PRDM16 expression was a significant marker to predict poor prognosis in pediatric AML. However, the significance of PRDM16 expression is unclear in adult AML patients. Methods A total of 151 adult AML patients (136 patients with de novo AML and 15 patients with relapsed AML) were analyzed. They were referred to our institution between 2004 and 2015 and our collaborating center between 1996 and 2013. The median length of follow-up for censored patients was 30.6 months. Quantitative RT-PCR analysis was performed using the 7900HT Fast Real Time PCR System with TaqMan Gene Expression Master Mix and TaqMan Gene Expression Assay. In addition to PRDM16, ABL1 was also evaluated as a control gene. We investigated the correlations between PRDM16 gene expression and other genetic alterations, such as FLT3-ITD, NPM1, and DNMT3A, and clarified the prognostic impact of PRDM16 expression in adult AML patients. Mutation analyses were performed by direct sequence analysis, Mutation Biased PCR, and the next-generation sequencer Ion PGM. Results PRDM16 overexpression was identified in 29% (44/151) of adult AML patients. High PRDM16 expression correlated with higher white blood cell counts in peripheral blood and higher blast ratio in bone marrow at diagnosis; higher coincidence of mutation in NPM1 (P = 0.003) and DNMT3A (P = 0.009); and lower coincidence of t(8;21) (P = 0.010), low-risk group (P = 0.008), and mutation in BCOR (P = 0.049). Conversely, there were no significant differences in age at diagnosis and sex distribution. Patients with high PRDM16 expression tended to be low frequency in M2 (P = 0.081) subtype, and the remaining subtype had no significant differences between high and low PRDM16 expression. Remarkably, PRDM16 overexpression patients were frequently observed in non-complete remission (55.8% vs. 26.3%, P = 0.001). Patients with high PRDM16 expression tended to have a cumulative incidence of FLT3-ITD (37% vs. 21%, P = 0.089) and MLL-PTD (15% vs. 5%, P = 0.121). We analyzed the prognosis of 139 patients who were traceable. The overall survival (OS) and median survival time (MST) of patients with high PRDM16 expression were significantly worse than those of patients with low expression (5-year OS, 17% vs. 32%; MST, 287 days vs. 673 days; P = 0.004). This trend was also significant among patients aged <65 years (5-year OS, 25% vs. 48%; MST, 361 days vs. 1565 days, P = 0.013). Moreover, high PRDM16 expression was a significant prognostic factor for FLT3-ITD negative patients aged < 65 years in the intermediate cytogenetic risk group (5-year OS, 29% vs. 58%; MST, 215 days vs. undefined; P = 0.032). Conclusions We investigated the correlations among PRDM16 expression, clinical features, and other genetic alterations to reveal clinical and prognostic significance. High PRDM16 expression was independently associated with non-CR and adverse outcomes in adult AML patients, as well as pediatric AML patients. Our finding indicated that the same pathogenesis may exist in both adult and pediatric AML patients with respect to PRDM16 expression, and measuring PRDM16 expression was a powerful tool to predict the prognosis of adult AML patients.

Abstract Background Secondary acute myeloid leukemia (sAML) describes patients (pts) with a history of malignant or non-malignant disease or AML secondary to environmental, occupational or therapeutic exposures. They are generally associated with poor outcome despite the use of intensive treatments. The impact of clinical features and type of treatment on pts' outcome is still not well established. In the current analysis we evaluated sAML pts who were treated in 13 EORTC collaborative trials conducted between May 1986 and January 2008. sAML pts in the database were pooled to characterize clinical features of the disease and evaluate changes in survival over these years (yrs). Method Main selection criteria were AML with bone marrows blasts ≥20% and documented history of prior malignancy, non-malignant disease and/or toxic exposure. AML-M3 and MDS without confirmed diagnosis ≥2 months before AML were excluded. All pts were eligible for standard treatment. Induction regimens were anthracycline and AraC based: 7+3, including etoposide, intensified with high dose (HD)-AraC randomized to standard doses (SD) in younger (AML12) or gemtuzumab ozogamicin in elderly pts. Consolidation regimens were age adapted. In mid-1980s, autologous transplant was tested vs a 2nd consolidation cycle (AML8A) in pts ≤45 yrs and thereafter used systematically in pts ≤60 yrs without available donor. Allogeneic transplant (Allo-SCT) was offered to pts ≤46 yrs with HLA-compatible sibling since mid-1980s and expanded in the last decade to pts up to 59 yrs. Selected pts were divided into 3 sAML cohorts, cohort A after MDS, cohort B after other malignant diseases and cohort C after non-malignant conditions and/or toxic exposure. Results Of 8858 pts enrolled in the 13 evaluated studies, 962 were sAML. Median age was 63 yrs (range 16-85), 413 were young (≤60 yrs) and 549 were elderly (≥61 yrs); 54% were males. Cohort A consisted of 509 pts (median age 64 yrs), cohort B of 362 pts (median age 59 yrs) and cohort C of 91 pts (median age 61 yrs). In cohort B, breast cancer (24%) and lymphoma (14%) were the most frequent primary tumors. Autoimmune diseases represented 22% of non-malignant conditions. In young pts, complete remissions (CR/CRi) rate was 59%; 55% in SD-AraC vs 89% in HD-AraC treated pts. Allo-SCT in CR1 was performed in 21% of all pts. The Allo-SCT rate increased from 5% before 1990, 20% in 1990-1999 to 25% from 2000 (20% in SD-AraC vs 31% of HD-AraC treated pts). CR/CRi was achieved in 45% of elderly pts. Median follow-up was 6 yrs. Median overall-survival (OS) was 14.5 months in young and 9 months in elderly pts. The 5-yr OS was 28% and 7% respectively. Five-yr OS was 11% in cohort A and 22% in both cohort B and C. Treatment outcome of younger pts according to disease features and treatment type over time in cohort A and B are detailed in table 1 & 2. Using Cox model stratified by cohort age, gender, WBC, risk group, year of treatment and HD-AraC were independent prognostic factors for OS. In the AML12 study, compared to denovo pts, sAML pts ≤45 yrs had worse outcome if treated with SD-AraC whereas a better OS was seen if treated with HD-AraC. In elderly pts only the good/intermediate risk group of cohort B had a relatively better 5-yr OS (15%). Conclusions The outcome of sAML in younger pts has improved over the yrs in parallel with HD-AraC introduction in induction of remission. HD-AraC should be considered for younger pts with sAML.

Abstract The therapeutic approach to the patient with acute myeloid leukemia (AML) currently evolves toward new frontiers. This is particularly apparent from the entree of high-throughput diagnostic technologies and the identification of prognostic and therapeutic targets, the introduction of therapies in genetically defined subgroups of AML, as well as the influx of investigational approaches and novel drugs into the pipeline of clinical trials that target pathogenetic mechanisms of the disease. In Section I, Dr. Bob Löwenberg reviews current issues in the clinical practice of the management of adults with AML, including those of older age. Dr. Löwenberg describes upcoming possibilities for predicting prognosis in defined subsets by molecular markers and reviews experimental strategies to improve remission induction and postinduction treatment. In Section II, Dr. James Griffin reviews the mechanisms that lead to activation of tyrosine kinases by mutations in AML, the consequences of that activation for the cell, and the opportunities for targeted therapy and discusses some examples of developing novel drugs (tyrosine kinase inhibitors) and their effectiveness in AML (FLT3). In Section III, Dr. Martin Tallman describes the evaluation and management of patients with acute promyelocytic leukemia, a notable example of therapeutic progress in a molecularly defined entity of leukemia. Dr. Tallman focuses on the molecular genetics of APL, current curative treatment strategies and approaches for patients with relapsed and refractory disease. In addition, areas of controversy regarding treatment are addressed.
