Abstract Study AML-BFM 98 aimed to improve prognosis by intensification and optimization of the initial therapy elements. Between 7/1998 and 6/2003, 473 children and adolescents < 18 years with de novo AML entered the multicenter AML-BFM 98 trial. Treatment was based on the results of study AML-BFM 93 and was similar in standard risk (SR) and high-risk (HR) patients (definition for SR [n=192]: FABM1/M2 with Auer rods, M4eo with ≤ 5 % blasts in the day-15 bone marrow, all patients with M3; HR: all others [n=281]). Treatment: After induction with AIE (cytarabine, idarubicin and etoposide) all patients (excluding FAB M3) were treated with HAM (high-dose cytarabine 3g/m2/12h x3 days and mitoxantrone 10mg/m2/day x2 days), which, in the previous study 93, was given for HR patients only. Subsequently all patients were randomly assigned to receive either the 6-week consolidation as in the previous studies or two short therapy cycles including higher doses of cytarabine but the same cumulative dose of anthracyclines. The following therapy elements, intensification with high-dose cytarabine/etoposide and maintenance, were similar in studies 93 and 98. Allogeneic stem cell transplantation from a family donor was restricted to HR patients only. Overall results: 418 of 473 (88%) patients achieved remission. Early death rate could be reduced compared to study 93: 3.2% vs.7.4%. Five-year survival, event-free survival (EFS) and disease-free survival (DFS) were 62%±3%, 49%±3% and 57%±3%, respectively. Estimated survival improved (study 93: 58%±2%, plogrank .03), pEFS and pDFS were similar to study 93 (50%±2% and 61%±2%, n.s.). Randomization results of the 6-week consolidation arm (n=191) vs. the 2-short-cycle arm (n=199) were similar (pEFS 51%±4 and 50%±4%, n.s.). However, total treatment duration was shorter (median 15 days) and morbidity was lower in the short-cycle arm (5 vs. 9 deaths in CCR). Five-year pSurvival in HR patients (surviving >.44years, median time to SCT) with or without SCT in 1. CR was similar: 69%±14% vs. 64%±4%; plogrank .35. There was no improvement of prognosis in SR patients (FAB M3 excluded) compared to the previous study 93 despite additional application of HAM (CR rate 93% vs. 89%, p(chi) .24, 5-years pEFS 62%±4% vs. 67%±4%; n.s.). Conclusion: The estimated survival is now in the range of 65%–70% for those patients who achieve remission. Results of study 98 show, that intensification of chemotherapy with HAM does not improve survival in SR patients. There is no difference in survival of HR patients receiving SCT in 1st CR compared to those with chemotherapy alone. Because improvement of prognosis can not be achieved by intensivication of therapy alone, optimizing the chemotherapeutic regimen by introducing less toxic, but similar effective therapy elements together with better supportive care strategies will reduce treatment related mortality and thereby improve survival in small steps.

Abstract INTRODUCTION: Autologous PBSC transplant is an important yet evolving treatment modality for patients with AML. However, the ideal mobilization regimen from which to collect PBSC remains in question. Previous reports have indicated that highdose cytarabine with etoposide is both safe and effective in terms of successful PBSC procurement, subsequent engraftment, and disease outcome. METHODS: At our institution from 1994 to 2007, 38 consecutive patients with de novo non-promyelocytic AML in first complete remission following conventional induction chemotherapy were consolidated with high-dose cytarabine (2000mg/m2 IV q12h × 8 doses, days 1–4) and etoposide (40mg/kg IV over 96h) followed by G-CSF 5 mg/kg subcutaneously starting d14 until completion of PBSC collection. Patients underwent myeloablative therapy with busulfan (1mg/kg po q6h × 16 doses, days –7 to -4) and etoposide (60 mg/kg IV over 10h, day -3) with PBSC infusion occurring on day 0 with daily G-CSF 5 mg/kg. Data regarding stem cell yield, engraftment and patient outcome was collected retrospectively. RESULTS: The average patient age was 44 years (range 19–70). Following consolidation, at least 2×106 CD34 cells/kg were isolated from all 38 patients with a median of 9.4×106 (range 2.2–43) CD34 cells/kg over a mean of 4 collections (range 1–11). Overall, 36 of 38 (95%) remained in CR and went onto PBSC transplant (one died from infectious complications during consolidation, one relapsed before transplant). The median number of stem cells infused was 8.8×106 CD 34 cells/kg (range 2.2–47). All 36 patients engrafted with the mean number of days to neutrophil recovery (ANC>500) being 11 (range 8–17) and the mean number of days to platelet recovery (>20,000) being 12 (range 8–19). Disease-free outcomes in patients undergoing PBSC transplant while in CR1 are presented in Figure 1. The 3y overall survival in all pts was 66%, and 56% at 5y. For good-risk cytogenetic patients, 3y OS was 78% and the 5y OS was 75%. For intermediate-risk cytogenetic patients, OS was 47% and 36% at 3y and 5y respectively. Three patients with poor cytogenetics were autulogously transplanted. One patient relapsed at day 111 and expired at day 450. The second patient remains in CR at day 246. The third patient relapsed at day 104 and expired at day 322. CONCLUSION: In patients with de novo non-promyelocytic AML in CR1, consolidation with high-dose cytarabine plus etoposide is safe and provides excellent yield of PBSCs upon growth factor accelerated hematological recovery. Subsequent engraftment after autologous transplanation is rapid. Our outcomes support the viability of this regimen in patients with good and intermediate-risk cytogenetics.

Abstract In order to further improve survival of children undergoing therapy for acute myeloid leukemia (AML), the multicenter clinical trial AML-BFM 98 intensified chemotherapy for standard risk (SR) patients (pts.). In addition, this randomized trial prospectively evaluated whether 2 short cycles of chemotherapy resulted in better prognosis than a 6-week consolidation. Patients and Methods: Between July 1998 and June 2003, 461 pts. < 18 years with de novo AML were enrolled in the trial AML-BFM 98. The SR group consisted of 170 (37%) pts. (FABM1/M2 with Auer rods or M4eo with ≤ 5 % blasts in the day 15 bone marrow; all pts. with FAB M3). All other pts. (n=291) were considered as high-risk (HR) pts.. In contrast to trial AML-BFM 93, a 2nd induction (HAM) was included in the treatment strategy for SR pts. (excluding FAB M3) which consisted of high-dose cytarabine (3g/m/12h x3 days) and mitoxantrone (10mg/m/d x2 days). Both SR and HR pts. were then randomly assigned to receive a 6-week consolidation or two short cycles of therapy. Compared to the 6-week consolidation, the short cycles contained higher doses of cytarabine, but the same cumulative dose of anthracylines. All other therapy elements [first induction (AIE; cytarabine, idarubicin and etoposide), intensification (HAE; high dose cytarabine, etoposide), and maintenance therapy] were identical in studies 93 and 98. Results: Overall, 407 out of 461 (88%) pts. achieved remission (CR). Five-year survival, event-free survival (EFS) and disease-free survival (DFS) were 59%±3%, 49%±3% and 55%±3%, respectively. Estimated survival and pEFS were similar to those of study 93 (58%±2% and 50%±2%, p logrank .09 and .80). Analysis of SR pts. (FAB M3 excluded) showed that the additional application of HAM did not improve the prognosis of SR pts. compared to AML-BFM 93 [CR rate 92% vs. 91%, p(chi)=.78; 5-year pEFS 58%±5% vs. 66%±4%; p logrank =.24]. However, when comparing HAM in study 98 and the 2nd chemotherapy cycle in study 93, significantly more severe infections (grade 3/4) occurred with HAM. Overall treatment related mortality in CR was 4% in both HR and SR pts., which was similar to trial AML-BFM 93. In addition, the outcome of pts. randomized for the 6-week consolidation was similar to that of the short cycles (p logrank .81). However, morbidity was lower in the short cycle arm (6 vs. 11 deaths in CCR, 2 vs. 4 in SR pts.). Conclusion: Our results indicate that in SR pts. with AML, a more intensive chemotherapy consisting of HAM does not result in improved survival. Therefore, new treatment options should be considered in this patient group. At the same time, optimizing treatment using the less toxic therapy with short cycles and improvement of supportive care strategies might help to reduce treatment related mortality and improve outcome in children with AML.

Abstract Abstract 17 Introduction: The prognosis of paediatric patients (pts) with Acute Myeloid Leukaemia (AML) has significantly improved over time, the published current probability of event-free survival (EFS) being in the order of 40–50%. We report the results of the AIEOP LAM 2002/01 Protocol, a multicentric prospective study conducted by Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP). Treatment was stratified according to the risk group at which the pt was assigned and the study was designed to evaluate if a large use of haematopoietic stem cell transplantation (HSCT) in high-risk (HR) pts was able to increase the 5-year EFS above 50%. Patients and Methods: Between 12/2002 and 12/2007, 217 children with de novo AML other than promyelocitic leukaemia were enrolled; 205 of them are evaluable. Children with Down syndrome were excluded. Pts with isolated AML1-ETO fusion transcript or anomalies of CBF-b achieving complete remission (CR) after the first induction course were considered to be at Standard Risk (SR), whereas all the others were assigned to the HR group. After 2 courses of 7-day induction therapy (idarubicin, cytarabine and etoposide: ICE 3+5+7), pts achieving CR received 2 consolidation courses, including high-dose cytarabine (HD-Ara-c), combined with either etoposide in the first course (AVE 3+4) or mitoxantrone in the second course (HAM 3+2). After consolidation, SR pts received a further cycle of 3-day HD-Ara-c, while HR children underwent either allogeneic (ALLO) or autologous (AUTO) HSCT depending on the availability of an HLA-identical relative. Children <1 year of age, as well as those with M7 variant, were eligible to be transplanted from alternative donors, namely unrelated donors (UD) or HLA-mismatched relative. A conditioning regimen including busulfan, cyclophosphamide and melphalan was employed for both AUTO and ALLO-HSCT. Pts given AUTO-HSCT had in vitro marrow purging with mafosfamide. Results: 34 (16%) and 171 (84%) pts were assigned to SR and HR groups, respectively. Overall, 82% of 205 pts achieved CR after induction, the early death and induction failure rate being 4,3% and 11,7%, respectively. Pts in CR Relapsed in 35%, died in 5%. With a median follow-up of 43 months (range 4-86), the 5-year probability of overall survival (OS), EFS, and disease-free survival (DFS) for the whole cohort were 70%, 55%, and 63%, respectively. In the SR group OS, EFS and DFS were 97%, 78% and 78%, respectively, while in the HR group were 64%, 50% and 60%, respectively. Notably, EFS for the 25 children with M7-AML was 54%; 24 infants had an EFS of 62%. WBC count at diagnosis did not influence EFS. In the HR group, the EFS of pts who did or did not have FLT-3 internal tandem duplication was 31% and 51%, respectively (p<0.05). The 38 pts with MLL rearrangement had an overall EFS of 47%; however, the prognostic value of MLL differed according to the partner gene, the EFS being 51%, 30% and 14% for children with MLL-AF9, -AF10 and -AF6, respectively. EFS was 62% for the 64 pts given AUTO HSCT, while it was 77% for the 57 pts given ALLO HSCT. Among this latter group, EFS was 80% and 83% for the 25 and 27 pts transplanted from an HLA-identical relative or an UD, respectively. The 5-year OS of AUTO-HSCT recipients was 75%, as 1/3 of these pts were rescued by an allograft in 2nd CR. Conclusions: AIEOP LAM 2002/01 study resulted in an EFS superior to 50%. The early-death rate was particularly low. The risk stratification adopted allowed to identify 2 groups with distinct prognosis (Fig1) and deserving post-remissional treatment of different intensity. The EFS of M7-AML and infant pts compares favourably with previously published results. Notably, among pts given ALLO-HSCT, the outcome was not influenced by the type of donor employed. Disclosures: No relevant conflicts of interest to declare.

PURPOSE Despite substantial progress in the treatment of acute myeloid leukemia (AML), fewer than 25% of patients survive free of leukemia for more than 5 years without allogeneic bone marrow transplantation (BMT). In this study we analyzed the results of one or more cycles of high-dose cytarabine-based consolidation chemotherapy as compared with allogeneic BMT in first remission. PATIENTS AND METHODS The results in 28 adult patients, aged 16 to 45 years, who underwent a closely HLA-matched BMT for AML in first remission were compared with those in 54 consecutive, age-matched, adult patients treated with one or more cycles of high-dose, cytarabine-based consolidation chemotherapy. RESULTS After a median follow-up of 4 years, the actuarial risk of leukemic relapse was considerably lower in the transplant group than in the group treated with consolidation chemotherapy (32% +/- 26% v 60% +/- 14%; P = .05). Treatment-related mortality, however, was much higher in the group treated with BMT (32% v 6%, P = .002). The actuarial disease-free survival at 5 years was not significantly different for the two groups (45% +/- 24% v 38% +/- 14%). CONCLUSIONS Our results show that BMT in first remission AML did not offer a disease-free survival advantage over intensive postremission consolidation chemotherapy. Larger studies are needed to identify patients who might benefit most from BMT.

Abstract CCG-2961 tested an intensively timed induction therapy consisting of cytarabine (AC), etoposide, thioguanine, dexamethasone, idarubicin and daunorubicin. Patients in remission after induction were randomized to a second induction course (Arm A) or a 3-drug combination of fludarabine, AC, and idarubicin (Arm B). Course 3 for patients with related donors was bone marrow transplantation (BMT); for those without donors, high dose AC/l-asparaginase. After Course 3 patients without donors were randomized to 14 infusions of Interleukin 2 (IL2) over 18 days or follow-up. CNS prophylaxis was intrathecal AC. Eligibility included all subtypes of de novo AML except acute promyelocytic leukemia and AML in patients with Down syndrome. CCG-2961 opened in Oct.1996 and closed in Dec. 2002. The DSMC suspended the study between Oct. 1999 and May 2000 while the 2961 Committee developed supportive care policies to reduce treatment-related mortality (TRM). CCG-2961 enrolled 900 de novo patients aged 3 days to 21 years, with 495 and 405 patients accruing pre-and post suspension respectively. Remission induction rate is 88.5%. With median follow-up of 3.6 years (range: 0 – 8.1 years), event-free survival (EFS) at 3 years is 44±3% and survival (OS) 57±3%. Disease-free survival (DFS) following Course 2 Arms A and B are not different, although relapse is significantly higher in Arm A (7.3% .vs. 3.1% P=0.018) and TRM more common in Arm B (7.9% vs.4.2% P=0.059), despite 7 less days of neutropenia in Arm B (P&lt;0.001). DFS is 65±9% for patients with a donor versus 50±5% for patients without a donor (P=0.005); respective OS, 74±8% and 66±5% (P=0.221). However, among 98 patients in CR1 with t(8;21) or inv(16) cytogenetics, outcomes in those without and with a donor were no different: DFS (61±12% vs. 72±18%, P = 0.49) and OS (78±10% vs. 77±17%, l P= 0.85). DFS with and without IL2 is 55±9% and 60±8%(P=0.606). Outcomes improved progressively over time. EFS pre- and post-suspension are 41±4% and 47±5%(P=0.038); OS, 52±5% and 63±5%(P=0.005); TRM is 17±3% pre- and 12±3% post-suspension (P=0.039). Factors predictive of inferior EFS are age &gt;17 years, Afro-American and Hispanic ethnicity, body mass index &lt;10th or &gt;95th percentile for age, absence of related marrow donor, WBC &gt; 50,000/mm3, karyotype with −7/7q, −5/5q- or &gt; cytogenetic 5 abnormalities, FLT3/ITD, &gt;15 % morphologic blasts on day 14 or &gt;0.5% immunologically detectable blasts at the end of induction. CCG-2961 confirms the efficacy and high TRM of intensively timed therapy. Neither fludarabine nor IL2 increases DFS or OS, and availability of a donor does not improve outcomes in those with favorable cytogenetics.

Abstract Background: Mutations in the NPM1 gene represent the most frequent alterations in patients with AML and are associated with a favourable clinical outcome. Patients and Methods: We analyzed 803 patients that were treated in the AMLCG2000 study. Patients with de novo or secondary AML or high-risk myelodysplastic syndrome (MDS) were randomly assigned upfront for induction therapy containing one course with standard dose and one course with high-dose cytarabine, or two courses with high-dose cytarabine, and in the same step received postremission prolonged maintenance or busulfan/cyclophosphamide chemotherapy with autologous stem-cell transplantation. At diagnosis mutations in the NPM1 and FLT3 gene were analyzed by routine molecular techniques. Results: The median age of all patients was 60 years and the median observation time 23 months. Results of the mutations status of FLT3 (FLT3-ITD) and NPM1 were available in 761/803 (94,8 %) and 690/803 (85,9 %) patients, respectively. NPM1 and FLT3-ITD mutation were found in 352 (51,1%) and 199 (28,9%), respectively. On the basis of these two molecular markers, patients were grouped in 4 subgroups: 1. NPM1+/FLT3−, N=214 (31%), 2. NPM1+/FLT3+, N=138 (20%); 3. NPM1−/FLT3−, N=276 (40%); NPM1−/FLT3+ (9%). The CR-rates were significantly higher in NPM1+ (74,4%) than in NPM1− (55,9%) patients, but were unaffected by the FLT3-ITD status. Overall survival (OS), event-free survival (EFS) and relapse free survival (RFS) was significantly higher in NPM1 positive and FLT3-ITD negative patients. In a multivariate analysis age, WBC, the presence of the NPM1 mutation and de novo AML were independent prognostic factors for the CR-rate. The NPM1− and FLT3 mutation status, age and LDH were identified as independent prognostic factors for RFS. To further characterize the biological effects of NPM1 and FLT3 mutations, we analyzed the in vivo blast cell clearance measured by the residual bone marrow blast cells one week after the end of the first induction cycle (d+16 blasts). The percentage of patients with adequate blast cell reduction (residual bone marrow blast &lt;10%) was significantly higher in NPM1+ patients (87,3%) compared to NPM1− (65,7%) patients. The presence of a FLT3-ITD mutation had no effect on early blast cell clearance. Conclusions: The presence of a NPM1 mutation represents an independent positive prognostic factor for the CR-rate and RFS/OS. In contrast, FLT3-ITD mutations do not affect the CR-rate, but have a negative prognostic impact on RFS and OS. The higher sensitivity of NPM1-positive blasts towards the induction therapy point to a central role of NPM1 in the regulation of apoptotic cell death in AML.

Abstract Abstract 1030 Poster Board I-52 Few clinical protocols have focused exclusively on the care of patients with therapy-related myeloid neoplasms (t-MN), and typically the disease confers a poor prognosis. We conducted a clinical trial exclusively for these patients. Between February 2003 and February 2009, we enrolled 32 adult patients with untreated t-MN. The median age was 56 years old (range, 23-83), and 38% were >60 years old. Eight patients (25%) had a total combined Charlson comorbidity index of >4, indicating that they were at high-risk for toxicity from the treatment, either due to older age or medical co-morbidities. T-MN developed following cytotoxic therapy for a malignant disease in 28 patients (88%), following cytotoxic therapy for rheumatologic disease in 2 patients (6%), and with immunosuppressive therapy after solid organ transplants in 2 patients (6%). The latency interval was highly variable, but the greatest fraction of patients (28%) experienced a latency of 4 - 9 years between their primary cytotoxic treatment and development of t-MN (median latency, 3.6 years; range 0.9-23 years). In 8 patients (25%), the latency was 2 years or less. 84% of patients had clonal cytogenetic abnormalities; 35% had a complex karyotype; 45% had abnormalities of chromosomes 5 or 7 or both.; 5 patients had t(9;11). All patients received induction chemotherapy with high-dose cytarabine (3,000mg/m2 over 4 hours) followed immediately by mitoxantrone (30mg/m2 over 1 hour), both given once on days 1 and 5 in a timed-sequential schedule. The complete remission (CR) rate after a single course was 66% and the partial remission (PR) rate was 16%, for an overall response rate of 82%. Grade 4 cardiac dysfunction occurred in 4 patients, resulting in the early death of one. Three of these patients had normal ejection fractions prior to beginning induction chemotherapy (including the patient who died), and one began therapy with an ejection fraction of 43%. Among the 21 patients who achieved a CR, 13 (62%) received consolidation therapy with allogeneic HCT, 4 (19%) received an autologous HCT, and 3 (14%) received only further chemotherapy. Three of the 5 patients who achieved a PR received an allogeneic HCT. Long-term disease-free survival (DFS) was observed in patients with each of the 3 modalities of consolidation therapy. The median overall survival (OS) was 399 days (range, 15-1972+), and OS at 1 year was 51%. Survival was significantly better among those patients who achieved a CR (median, 673 days) compared to those who had a PR (median, 126 days) to induction chemotherapy (P=0.003). OS at 1 year was 74% for patients who had achieved a CR compared with 20% for patients who had achieved a PR to induction. Median DFS was 415 days, with 59% of patients remaining disease-free at 1 year. OS was significantly longer in patients who underwent HCT compared to those who did not. The median survival for patients who received an allogeneic HCT was 673 days (range, 74-1798+) compared to 399 days for patients who received an autologous HCT (range, 353-917+), and 93 days for patients who received no transplant (range, 15-1972+) (P=0.002). OS at 1 year was 72% for patients who had undergone an allogeneic HCT, 75% for patients who had an autologous HCT, and 17% for patients who had not received a transplant. The DFS at 1 year was 67% for patients who underwent either an allogeneic or autologous stem cell transplant compared to 25% for those who did not have a transplant. To date, 9 patients (28%) remain alive and disease-free: 7 (22%) after allogeneic HCT; 1 after autologous HCT; and 1 after consolidation with only chemotherapy. Overall, remission induction therapy with high-dose cytarabine and mitoxantrone is an effective and tolerable regimen for patients with t-MN, allowing aggressive consolidation regimens, HCT, and long-term disease-free survival.

Abstract Abstract 3621 Acute myeloid leukemia (AML) has a dismal prognosis in elderly population because of intrinsic chemoresistance and frailty of patients. High-dose Cytarabine (HiDAC) in induction therapy did not improve the CR in younger AML patients and recent guidelines discourage this approach in elderly because of high extrahematological toxicity. Amifostine showed to selectively protect normal Hemopoietic progenitors from chemotherapy and we previously successfully tested the feasibility of an induction schedule including HiDAC (3 g/m2 days 1,2,3,4,5), Idarubicin 40mg/m2 on day 3 preceeded by Amifostine (740 mg/m2). We designed a prospective observational study including the same induction schedule, aimed to evaluate the outcome (CR rate, OS and EFS) of a larger population of fit AML elderly patients. Fit patients, selected according the Multidimensional Geriatric Assessment, received 1–2 courses and underwent PBSC mobilization after consolidation. Patients who collected ≥3×10e6CD34+/kg received ASCT, while poor mobilizers were considered for alternative regimen including Allogeneic transplantation from an HLA-matched sibling, chemotherapy (CHT) or Gemtuzumab-Ozogamicin (GO). We registered 156 consecutive patients, aged >59 yrs; 56 were unfit for intensive induction chemotherapy and received only palliative care; 100 (64%) fulfilled the inclusion criteria of our protocol: 91 received the scheduled induction regimen, while 9 received a Fludarabine regimen because of reduced cardiac function. These patients were not included in the response evaluation, but were considered for the outcome (according to the ITT criteria). Patients' characteristics are shown in table 1. CR was achieved in 73.6% of patients; multivariate analysis showed secondary disease as predictive of poor response, with a 65% CR rate (RR = 2.54; 95% CI: 1–6.45; p= 0.05) vs 83% in primary disease. Induction death rate was 5% and not influenced by any prognostic factors. The median time to achieve neutrophil>500× 106/L and platelet>20,000×106/L, were 17 and 19 days (ranges of 9–29 and 3–47 respectively). The main extrahematological toxicity were grade 3–4 mucositis (13%) and hepatic toxicity (9%). We also observed 66 grade III-IV febrile neutropenia/infectious episodes. Overall 65 patients received a first consolidation course and mobilization for PBSC harvest; we observed 6 TRD, a 3% of grade 3–4 hepatic and neurological toxicity and 6% of grade 3–4 cardiac toxicity; in 4 patients we observed rapid early leukemia relapse; overall 55 patients were eligible for post-consolidation therapy. Only 24 patients achieved a succesfull PBSC mobilization and ASCT was performed in 21 (2 relapsed and died before ASCT and 1 received Allogeneic Transplant). Thirty-one patients were poor mobilizers: 3 received Allogeneic Transplant, 3 CHT, 5 stopped treatment because of persistent aplasia and 20 received low-dose GO (3 mg/m2 monthly for 3 times and every 3 months after; median: 3, range 3–6 courses). With a median follow-up of 70 months (range 24–124) 21 patients are alive (19 in continuous CR), 6 after ASCT, 13 after GO, 1 after CHT. The 8 yrs Overall Survival (OS), Disease Free Survival (DFS) and Event Free Survival (EFS) are respectively 20.4% (median: 11.4 months), 24,3% (median 8.8 months) and 17,7% (median: 8.8 months). Secondary AML and hyperleukocytosis are factors predictive of OS at the multivariate analysis. Patients with secondary disease have a 1.59 RR to die with a 9.9% 8 yrs OS vs 27.1% of patients with primary AML. Patients with WBC ≥50,000/mcl had a 2.2 RR to die with a 0% OS at 33 months vs 23.2% 8 yrs OS in patients with WBC<50,000/mcl. In conclusion our novel intensive induction regimen for fit AML patients is safe and effective both in term of CR rate and outcome. The ASCT feasibility was confirmed to be poor in this setting (21%) while GO low-dose seems to be feasible and promising. Finally our prospective study in 156 elderly AML patients describes the real-life outcome of this setting, suggesting that two thirds of AML elderly patients are fit for intensive treatment and that long term OS can be achieved in a relevant proportion of patient with de novo AML.

Results of postremission chemotherapy for adults with acute myelogenous leukemia (AML) were assessed in two sequential prospective studies involving similar induction therapy and two courses of intensive consolidation treatment. Fifty-six patients achieving remission on the acute leukemia protocol (ALP3) study received high-dose cytarabine and daunorubicin as course one and standard-dose cytarabine and daunorubicin as course two. Results are compared with forty-six patients achieving remission on the ALP2 study who received azacitidine and doxorubicin as consolidation course one and standard-dose cytarabine, daunorubicin, and thioguanine as course two. The ALP3 regimen resulted in a significantly improved 5-year disease-free survival of 32% +/- 19% versus 20% +/- 11% for the ALP2 study (P = .03). Survival from remission was also improved, 40% +/- 14% versus 24% +/- 12% (P less than .01). Favorable prognostic factors for disease-free survival included receiving the ALP3 treatment regimen, absence of a prior preleukemic syndrome, and female sex. These factors and younger patient age were significant for survival following first chemotherapy and survival after achieving remission. Six of 34 patients who relapsed after receiving the ALP3 regimen successfully achieved prolonged second remissions with high-dose cytarabine-based chemotherapy and/or allogeneic bone marrow transplantation (BMT). Overall survival for adults less than or equal to 45 years of age was 58% +/- 19% with the ALP3 postremission chemotherapy regimen, comparable to most studies of BMT for AML in first remission. Actuarial 5-year survival for ALP3 patients greater than 60 years of age was 18% +/- 20% with no improvement compared with ALP2.

Relapsed/refractory acute myeloid leukemia (RR-AML) is associated with poor prognosis and long-term disease-free survival requires allogeneic hematopoietic cell transplantation (allo-HCT). Limited data exists, regarding the optimal regimen to obtain remission prior to allo-HCT. Single agent high-dose cytarabine (10–12 doses administered every 12 hours) has been previously used as induction therapy. Six-dose high-dose cytarabine (HiDAC-6), commonly used as a consolidation regimen, has never been evaluated as induction therapy. We present a retrospective review of 26 consecutive patients with RR-AML receiving single agent cytarabine 3 g/m2intravenously every 12 hours on days 1, 3, and 5 for a total of six doses (HiDAC-6). Median follow-up for surviving patients was 10.4 months (range 1.6–112.2 months). Complete remission was obtained in 62% (54% CR and 8% CRi) of the patients. The median relapse-free survival (RFS) was 22.3 months (range 0.7–112 months), event-free survival (EFS) was 4.7 months (range 0.5–112 months), and the overall survival (OS) was 9.6 months (range 1–112 months). Thirty-five percent of patients were able to subsequently proceed to allo-HCT. Treatment-related toxicities included neutropenic fever (38%), infection (35%), neurotoxicity (8%), and skin toxicity (8%). This is the first study to demonstrate HiDAC-6 as an active treatment option for younger patients with RR-AML which can effectively serve as a bridge to allo-HCT without significant toxicity.
