Abstract Purpose: Chromosome 17 abnormalities define a group of patients with acute myelogenous leukemia (AML) (Nahi, H. et al. Leukemia and Lymphoma2008;49:508) with poor outcomes. We analyzed the additional impact of chromosome 17 abnormalities (−17, −17p, −17q, der17) among patients with AML and cytogenetic abnormalities traditionally considered to be of adverse prognosis. Patients and Methods: 1086 patients with AML [excluding inv 16, t (8;21), t (15;17), Diploid/-y abnormality] were included in this analysis. Based on cytogenetic abnormalities patients were grouped into: −5,−7,−5and −7, complex. The following parameters were included in uni and multi-variate analysis: age, performance status, WBC, hemoglobin, platelets, marrow blast percentage, bilirubin, creatinine, albumin, LDH, chromosome 17 abnormality (yes/no). Results: Four hundred and fourteen (45%) patients achieved complete remission (CR) or CR with incomplete platelet recovery (CRp) and 267 (64.5%) patients relapsed. Two hundred seventy (24.9%) patients had abnormalities of chromosome 17. Abnormalities of chromosome 17 were associated with lower CR or CRp rate (p=0.02) and higher possibility of having cytogenetic abnormality of −5 or −7 (p<0.0001). Multivariate analysis showed that patients with abnormalities of chromosome 17 had worse overall survival (OS) compared to patients without (p= 0.003)(Fig.1). Multi-variate analysis within cytogenetic subgroups showed that chromosome 17 abnormalities were associated with worse OS in patients with chromosome 5 abnormality(p=.02) (data not shown) and in those with complex cytogenetics (p=.04)(Fig.2) and not in patients with chromosome 7 (p=.17)or combined 5 and 7 abnormalities (p=.33). Similar analysis restricted to patients achieving CR/CRp after induction therapy showed that impact of chromosome 17 abnormalities on relapse free survival (RFS) mirrored their impact on OS. Conclusion: chromosome 17 abnormalities are associated with worse OS and RFS in patients with AML and adverse cytogenetics and have additional negative impact on the outcomes in certain well-known adverse cytogenetic subgroups.

PURPOSE Despite improvement in chemotherapy and supportive care over the past two decades, overall survival for patients with acute myelogenous leukemia (AML) remains poor; only 25% to 30% of individuals with this disorder will be cured. In 1987, we initiated a prospective multiinstitution study designed to improve long-term survival in adults with AML. METHODS We modified the usual 7-day treatment scheme of daunorubicin and cytarabine with high-dose cytarabine (HiDAC) on days 8 through 10 (3 + 7 + 3). Allogeneic or autologous bone marrow transplantation (BMT) was offered to all patients who entered complete remission (CR) to decrease the rate of leukemic relapse. Data were analyzed by intention to treat. RESULTS CRs were achieved in 84 of 94 patients (89%; 95% confidence interval [CI], 83 to 95). Because of the high remission rate, factors previously thought to predict outcome, such as cytogenetics, WBC count, French-American-British (FAB) classification, sex, and age, were not useful prognostic variables. The overall survival rate for the entire cohort of patients from data of diagnosis is 55% at 5 years. Sixty percent of all patients who achieved a CR underwent marrow grafting. There was no significant difference in event-free survival (EFS) at 5 years comparing patients assigned to receive allogeneic BMT with patients assigned to receive autologous BMT (56% v 45%, P = .54). CONCLUSION The long-term disease-free survival observed in this study is excellent compared with historical data. This improvement in survival is probably due to the high rate of remission induction, as well as to the effective nature of the consolidation therapy.

6528 Background: Prior modulation with fludarabine increases cytarabine-triphosphate (ara-CTP) accumulation and granulocyte-colony-stimulating factor (G-CSF) increases the fludarabine-triphosphate (F-ara-ATP) levels in leukemic blasts. Our front-line regimen of fludarabine, cytarabine and filgrastim (FLAG) based on this rationale showed improved event-free survival compared to anthracycline and cytarabine based regimens in patients (pts) with core-binding factor acute myelogenous leukemia (CBF-AML). Medical Research Council AML 15 trial reported survival benefit from addition of gemtuzumab ozogamicin (GO) to chemotherapy regimens in patients with favorable-risk cytogenetics AML. Methods: In a clinical trial combining GO (3 mg/m2 IV) with FLAG (FLAG-GO) in newly diagnosed CBF-AML, pts received GO on day 1 of induction and of post-remission cycles 2 or 3 and 5 or 6 in addition to FLAG. FLAG regimen was comprised of fludarabine 30 mg/m2 and cytarabine 2 gm/m2 IV daily (both for 5 days in induction and 3-4 days in post-remission cycles) with filgrastim started on day-1 and continued till neutrophil recovery. Pts who received one non-FLAG-GO induction could enroll irrespective of their remission status. Results: Fifty pts [30 with t(8;21) and 20 with Inv16] have been enrolled [5 of 50 (10%) were in remission at enrollment from prior induction]. Median age is 48 years (range, 19-76), median WBC count 12.3 x106/L (range, 1.3-97.2); 12 patients (24%) were >60 years of age and frequency of kit mutation is 8%. Complete remission with or without platelet recovery (CR/CRp) was achieved in 43/45 (96%) pts with 2 deaths in induction. With 6 planned consolidations, the median number of consolidation treatments received is 5 (range, 0-6). Two-thirds of pts needed dose reduction during post-remission cycles. Seven (14%) pts [t(8;21)= 5, Inv 16=2] relapsed and with a median follow-up of 34 months (range, 15-54 months) the relapse-free survival rate is 83%. Conclusions: FLAG-GO is a highly effective regimen and has resulted in high rate of relapse-free survival in pts with newly diagnosed CBF AML.

One hundred thirty-three children with acute myelogenous leukemia (AML) entered the multicenter Pediatric Branch of the Italian Association Against Leukemia trial AIEOP/LAM 8204 between July 1982 and May 1986. Induction therapy consisted of two courses of daunomycin (DNM) plus cytosine arabinoside (Ara-C). Those patients who achieved remission were given four courses of consolidation with DNM, 6-thioguanine (6-TG) and escalated doses of Ara-C followed by six courses of sequential continuation therapy using monthly pairs: etoposide (VP-16)/Ara-C, Ara-C/6-TG, and DNM/Ara-C. Periodic intrathecal Ara-C was used for CNS prophylaxis. One hundred seven (80%) children achieved complete remission (CR). Kaplan-Meier estimates of 3-year disease-free survival (DFS) and event-free survival (EFS) are 41% and 33%, respectively. Relapses occurred in 34 patients after 5 to 97 weeks (32 marrow; 2 marrow plus CNS). Overall, 14 patients died of complications during treatment (nine during induction; five during the postremission phase), mostly from infection. Risk factor analysis showed that induction failures occurred predominantly in children with French-American-British (FAB) M5 and in those with elevated leukocyte counts; by step-up Cox analysis, only FAB subtype was predictive of remission success. None of the variables examined was significant for predicting the duration of remission. Hyperleukocytosis was predictive of a significantly worse EFS rate. These results are encouraging and further support the use of intensive chemotherapy programs for childhood AML.

Abstract Background: Fludarabine, cytarabine and G-CSF (FLAG) based regimens have resulted in marked improvement in newly diagnosed core binding factor (CBF) acute myelogenous leukemia (AML)(1-3). Addition of gemtuzumab ozogamicin (GO) to chemotherapy has also improved survival outcomes in CBF-AML(4). In 2007 we initiated a frontline study of FLAG-GO in newly diagnosed CBF-AML but after withdrawal of GO from US market, GO was replaced with idarubicin (FLAG-Ida). We report on mature data including early molecular response in patients treated in these sequential protocols. Methods: One hundred and forty five patients [Median age, 48 years (range, 19-78 years) were treated in these sequential protocols (FLAG=GO=50, FLAG-Ida= 95 patients). The treatment groups were comparable for age and distribution of cytogenetic (T8;21 or Inv16) subgroups (p≥0.5). FLAG regimen has been published before(2), GO was administered at 3 mg/m2 on day 1 in induction and in 2 consolidations out of planned 6 and idarubicin was administered at 6 mg/m2 on days 3 and 4 in induction and on day 2 in one of the consolidation cycles out of planned 6. Serial assessment of fusion transcript product relevant to the cytogenetic abnormality was performed in bone marrow samples at baseline, end of induction and every 2-3 cycles thereafter. Results: All except 3 patients (2 induction deaths) achieved remission (98%). After median follow up of 5 years, 5 year overall survival (OS) and relapse free survival (RFS) for the entire cohort is 77% and 72% respectively. There were no differences in OS among FLAG-GO vs FLAG-Ida (p=0.3) and Inv16 vs T(8;21) (p=0.6). While RFS was similar among Inv 16 and T(8;21) subgroups, it was significantly better among the cohort treated with FLAG-GO compared to FLAG-Ida (p=0.04)(Fig 1). We confirmed our earlier report of higher than 3 log reduction of fusion transcript ratio at end of induction(5) being most indicative of sustained RFS (p=0.006) (Fig 2) and this end point was more frequently achieved in the FLAG-GO cohort (57%) compared to FLAG-Ida cohort (29%) (p=0.002). On the other hand, within each regimen there was no difference in RFS between Inv 16 andf T(8;21) subgroups (p=0.3) (Fig. 3). SAEs were mostly related to cytopenias and associated infectious complications for both regimens and no hepatic veno-occlusive disease (VOD) was encountered. Presence of KIT, RAS, FLT3 mutations individually or in combination did not have any impact on outcomes. Conclusion: Compared to idarubicin, GO when added to FLAG based frontline induction/consolidation regimen results in better early molecular responses and improved relapse free survival in CBF AML. Our current frontline protocol is exploring safety and efficacy of addition of both GO and Ida to FLAG based regimen.

The value of a postremission treatment in acute myelogenous leukemia (AML), with alternating combinations of non-cross-resistant drugs, has been prospectively assessed. Of 515 evaluable patients, 347 (67.4%) entered into complete remission (CR), following induction treatment with daunorubicin (DNR), vincristine (VCR), and cytosine arabinoside (ara-C). After one consolidation course, 248 patients were randomized for six courses of intensive maintenance: either repeated treatment with DNR-VCR-ara-C, or alternating treatment where amsacrine (AMSA) was combined with high dose ara-C on cycle 1,3, and 5 and with 5- azacytidine on cycle 2, 4, and 6. Ninety-nine patients were not randomized: 57 were introduced in a bone marrow transplantation (BMT) program, and 42 went off study, mainly for treatment toxicity or refusal. The main prognostic factors for achievement of CR were performance status, cytogenetics, and age, and for the disease-free survival (DFS): age and number of courses to CR. The rate of second remission was fairly high (64%) for patients relapsing off therapy. The DFS appeared identical (median, 53 weeks), in the two randomized arms, the alternating treatment not showing superiority to the repeated one, in spite of an increased toxicity. The median overall survival for patients achieving a CR was 90 weeks. The reason for the failure of alternating maintenance treatment to improve the DFS is probably related to an insufficient dose intensity: five patients who relapsed during maintenance arm B achieved a second CR with a more intensive combination of high-dose ara-C and AMSA. In addition, 60 patients underwent a BMT (43 allogeneic and 17 autologous). The DFS of patients treated with allogeneic BMT tended to be superior to the one obtained with the chemotherapy program. However the overall survival, as well as the event-free survival, seemed equivalent, including patients who relapsed before the planned BMT. Comparisons between allogeneic BMT, autologous BMT, and intensive consolidation during first CR deserve further prospective studies in AML.

Purpose To evaluate the safety and efficacy of the combination of the histone deacetylase inhibitor vorinostat with idarubicin and ara-C (cytarabine) in patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). Patients and Methods Patients with previously untreated AML or higher-risk MDS age 15 to 65 years with appropriate organ function and no core-binding factor abnormality were candidates. Induction therapy was vorinostat 500 mg orally three times a day (days 1 to 3), idarubin 12 mg/m2 intravenously (IV) daily × 3 (days 4 to 6), and cytarabine 1.5 g/m2 IV as a continuous infusion daily for 3 or 4 days (days 4 to 7). Patients in remission could be treated with five cycles of consolidation therapy and up to 12 months of maintenance therapy with single-agent vorinostat. The study was designed to stop early if either excess toxicity or low probability of median event-free survival (EFS) of more than 28 weeks was likely. Results After a three-patient run-in phase, 75 patients were treated. Median age was 52 years (range, 19 to 65 years), 29 patients (39%) were cytogenetically normal, and 11 (15%) had FLT-3 internal tandem duplication (ITD). No excess vorinostat-related toxicity was observed. Induction mortality was 4%. EFS was 47 weeks (range, 3 to 134 weeks), and overall survival was 82 weeks (range, 3 to 134 weeks). Overall response rate (ORR) was 85%, including 76% complete response (CR) and 9% in CR with incomplete platelet recovery. ORR was 93% in diploid patients and 100% in FLT-3 ITD patients. Levels of NRF2 and CYBB were associated with longer survival. Conclusion The combination of vorinostat with idarubicin and cytarabine is safe and active in AML.

PURPOSE This study was conducted to assess the comparative values of allogeneic bone marrow transplantation (BMT) and autologous bone marrow transplantation (ABMT) with sequential postremission chemotherapy (SPC) in children with acute myelogenous leukemia (AML) in first remission. PATIENTS AND METHODS From March 1987 to March 1990, 161 assessable patients younger than 15 years of age with newly diagnosed AML were treated uniformly with two courses of daunorubicin and standard-dose cytarabine. After initial consolidation with a course of daunorubicin, cytarabine, and thioguanine (DAT), patients in complete remission (CR) were randomized to receive either ABMT or SPC, except for those with an HLA-matched sibling who were assigned to undergo BMT. SPC consisted of three additional courses of DAT, followed by three pairs of drugs administered sequentially for a total of six cycles. RESULTS Overall, 127 of 161 patients attained CR (79%). The estimated probabilities of survival and event-free survival (EFS) at 5 years for all patients were 42% and 25%, respectively (median follow-up, 28 months). For the 127 complete responders, the 5-year probability of disease-free survival (DFS) was 31%, with a cumulative risk of relapse of 64%. For the purpose of this study, all complete responders were evaluated for analysis of disease outcome according to the intent-to-treat principle, regardless of whether they actually received the intended therapy. The 5-year DFS was 51% for the BMT group (n = 24), significantly higher (P = .03) than that observed for the other cohorts: 21% for ABMT (n = 35), 27% for SPC (n = 37), and 34% for a group of 31 nonrandomized (NR) patients. Bone marrow relapse was the most frequent cause of postremission failure in all therapeutic subgroups, including the BMT cohort, in which no deaths attributable to the toxicity of the procedure were recorded. CONCLUSION The results of this study show that BMT is more effective than ABMT or SPC in preventing leukemia relapse and extending DFS duration in children with AML in first remission.

Abstract We designed a protocol (VAPA) that featured 14 mo of intensive postremission induction chemotherapy in an effort to improve remission durations for patients with acute myelogenous leukemia (AML). One hundred and seven patients under 50 yr of age were entered into this study. The rate of complete remission is 70%. A Kaplan-Meier analysis of patients entering remission predicts that 56% +/- 7% (+/-SE) of patients less than 18 yr and 45% +/- 9% of patients aged 18–50 yr will remain in remission at 3 yr (median follow-up is 43 mo). Patients with the monocytic subtype had a statistically significant shorter duration of remission (2-sided p less than 0.05). There was a high incidence of primary CNS relapse in children. Thirty-one of 41 patients who completed the regimen remain in remission without maintenance therapy. We conclude that the VAPA protocol continues to offer a promising approach to treatment of AML.
