Abstract Introduction Acute Myeloid leukemia (AML) is a heterogeneous group of malignant disorders of myeloid hematopoetic cells. These cells have a maturation arrest in different stages of development leading to accumulation of immature cells. This gives rise to the different symptoms and signs of disease secondary to anemia, thrombocytopenia and neutropenia. The current WHO classification broadly divides AML into 4 main groups based on morphology, immunophenotyping, genetics and clinical features. These include AML with recurrent genetic abnormalities, AML with myelodysplasia related changes; therapy related AML and AML not otherwise specified (NOS). Therapeutically AML can be divided into 2 main groups; Acute promyelocytic leukemia (APML) and non APML. Methods Tawam Tumor registry was searched for patients with diagnosis of AML from January 2010 till December 2012. Patient records were then reviewed and data was collected. Results We identified 49 patients with pathologically confirmed diagnosis of AML. 19/49 patients were diagnosed with AML with recurrent cytogenetic, 5/49 with MDS related or therapy related and 25 with AML NOS Cytogenetic Analysis of this cohort of 49 patients with AML showed that 15 patients (30%) had APML with 15;17 translocation, 4 patients had 8;21 translocation, 5 had complex or poor risk cytogenetic while 13 had normal karyotype. In 12/49 patients Karyotyping failed due to growth failure. Status of FLT3 and NPM1 are not known for the entire cohort. Demographics The median age of the cohort was 38 years (range 20 to 84 years). Older adults (age 65 years or more) make a minority of this cohort (8%). Male to female ration was 3.5:1. Treatment In patients with Non APML Induction therapy was a combination of Cytarabine and Idarubicin for adults < 65 years of age and with good performance status. Older adults or adults with poor performance status or co-morbidities were either given hypomehtylating agents, Clofarabine or supportive care. Patients achieving complete remission (CR) were given consolidation with High Dose Cytarabine (HIDAC) as per CALGB protocol. Only a minority of patients were able to go for allogeneic stem cell transplantation in CR1 Patients with APML were treated with ATRA, Idarubicin/Mitoxantrone and Cytarabine as per PETHEMA protocol on a risk adjusted plan. This was followed by 2 year maintenance with ATRA, 6 MP and Methotrexate. Outcome of Treatment In non APML patients 62 % (17) achieved CR with induction therapy. Induction therapy failure was observed in 18 % (5) while there were 5 early deaths observed (during aplasia). 7 patients were treated with hypomethylating agents or best supportive care. Only 1patient was able to achieve CR (after cycle 4 of 5-azacitidine). Consolidation therapy was given to 17 patients achieving CR. With a median follow up of 15 months (range 9-24 months) 9 patients are alive and disease free while 17 patients have been lost to follow up. 8 out of these 17 patients were in remission at their last follow up. In APML patients the CR rate was 93%. There were no cases of induction failure and only 1 case of early death (7%) due to hemorrhage. With a median follow up of 17 months (range 11-41 months) 11 patients are in molecular CR while 3 have been lost to follow up. Conclusion This is the first analysis of patients who were diagnosed with AML in a tertiary care center in UAE. The results show that the median age of patients our cohort is low as compared to international reports (approximately 38 vs. 65 years). Older adults (> 65 years of age) make only a minority of the AML cohort in Tawam Hospital. Response to induction therapy is comparable to international standards (60-80%) for AML and > 90% for APML. We also report a twofold higher incidence of APML as compared to internationally reported data (30% vs.12%). This has a very significant diagnostic and therapeutic impact on the management of AML patients at our institute leading to increase vigilance and institution of ATRA at the earliest clinical suspicion of APML.

Acute Myeloid

Abstract The prognosis for younger adults (≤ 55–60 years) with acute myeloid leukemia (AML) has improved during the last four decades. However, there has been little progress in the treatment of older adults. This disappointing observation is important because the median age of patients with AML is about 70 years. Approximately 60%–80% of younger adults with AML achieve complete remission (CR) with the cytotoxic agents cytarabine and an anthracycline such as daunorubicin or idarubicin or the anthracenedione mitoxantrone. However, only 30%–40% of such patients are alive and disease-free at 5 years. Among older adults, CR is achieved in 40%–55%, but there are very few long-term survivors. Many studies have evaluated the impact of alternative doses and schedules, as well as additional cytotoxic drugs, on the prognosis for this group of patients. The outcome has not improved substantially beyond that achieved with conventional doses of an anthracycline and cytarabine followed by high-dose cytarabine consolidation. Several factors identified at diagnosis can predict outcome. The most important of these is the karyotype of the leukemic cells. Another critical factor is the presence of transmembrane transporter proteins, which confer multidrug resistance and mutations in or overexpression of specific genes such as WT1, C/EBPα, BAX, and BCL-2/BAX ratio, BAALC, EVI1, KIT and FLT3. The development of specific agents directed at gene mutations, signal transduction pathways and unique cell surface antigens provide the foundation for new therapeutic strategies. Such agents include the immunoconjugate gemtuzumab ozogamicin, multidrug resistance inhibitors, farnesyltransferase inhibitors, histone deacetylase and proteosome inhibitors, antiangiogenesis agents, FLT3 inhibitors, apoptosis inhibitors, and nucleoside analogs. All of these agents can potentially address the heterogeneous abnormalities in AML and significantly improve the outcome for patients.

Abstract Acute myeloid leukemia (AML) is a disease of the elderly, but less than half of these patients are offered therapy despite the evidence of better survival with treatment in this patient population. Assessing fit, vulnerable, and frail older adults with AML remains a challenge for the treating oncologist. A majority of AML patients are elderly and often have significant comorbidities, lack of social support, and older caregivers. Performance status (PS), a subjective measure of how a patient will tolerate cancer chemotherapy, has been strongly correlated with mortality in older AML patients. However, a large portion of older adults have poor PS as a result of their underlying AML, and these patients may end up being undertreated. Conversely, some patients with excellent PS unexpectedly end up with excessive toxicity and mortality. The treating physician thus needs a more objective and comprehensive method to differentiate patients along the fit-frail spectrum irrespective of their chronological age. For more than a decade, comprehensive geriatric assessment has been shown to improve routine oncology assessment by adding information about the functional, emotional, cognitive, and social status of older patients with cancer. In addition to the chronological and functional age, there is an attempt to quantify a patient’s biological age to aid in better decision making. This chapter attempts to review the clinical challenges of AML treatment in the elderly population and to highlight the current literature and future research required to be able to assess fitness and maximize therapeutic options in this heterogeneous patient population.

Abstract The most effective reinduction regimen for acute myeloid leukemia (AML) patients who do not achieve complete remission (CR) after one cycle of cytarabine combined with an anthracycline is not well established. In an effort to search for new synergistic and non-cross resistant antileukemic regimens different chemotherapeutic combinations have been investigated in refractory AML patients. Multiple regimens including high dose cytarabine, anthracyclines, fludarabine and etoposide have been used with CR rates up to 40%. Mitoxantrone and etoposide have activity in AML as induction agents but their role in reinduction in patients not responding to first line therapy has not been fully established. In the current retrospective study we evaluated the efficacy and toxicity of mitoxantrone and etoposide in AML patients treated at our institution who did not respond to first induction therapy with cytarabine and an anthracycline. A total of fifty seven AML patients were treated with mitoxantrone and etoposide (mean age 55 years, range 18–75 years). Twenty four patients were treated with mitoxantrone 10 mg/m2/d and etoposide 100 mg/m2/d both administered intravenously, days 1 to 5 (regimen 5+5) and thirty three patients were treated with mitoxantrone 10 mg/m2/d administered intravenously days 1 to 3 and etoposide 100 mg/m2/d administered intravenously, days 1 to 5 (regimen 3+5). Twenty six of fifty seven patients (46%) achieved CR. CR was achieved in 38% of patients (9/24) treated with the 5+5 regimen and 52% of patients (17/33) treated with the 3+5 regimen. Mean blast percentage before treatment with mitoxantrone and etoposide was 25% in patients who achieved CR vs 40% in patients who did not achieve CR (p < 0.03). Grade 3/4 hepatic toxicities were seen in 5% (3/57) of patients and there were no grade 3 or 4 renal toxicities. The median duration of neutropenia in patients achieving CR was 29 days after reinduction. 10% (6/57) of the patients died from infectious complications. Cytogenetic analyses were performed prior to first-line therapy in all patients. Patients with favorable cytogenetics treated with etoposide and mitoxantorne had 100% CR (3/3), patients with standard cytogenetics had 58% CR (19/33) and patients with unfavorable cytogenetics had 19% CR (4/21). Overall CR was achieved in 61% (22/36) of patients with favorable and standard cytogenetics. Our data suggest that the combination of etoposide and mitoxantorne is an active and well tolerated regimen, especially in patients with favorable and standard cytogenetics, and warrants further studies in prospective trials.

Abstract Abstract 1011 Poster Board I-33 Background: Addition of purine analogues to standard induction therapy of acute myeloid leukemia (AML) had previously been demonstrated to increase complete remission rate. The aim of this study was to analyze whether the use of cladribine or fludarabine during induction and consolidation increases the risk of infectious complications. Material and methods: 118 AML patients, included in two consecutive randomized trials between 1999-2006 in a single centre were analyzed. Induction therapy consisted of daunorubicin + cytarabine (DA-7, n=53) alone or in combination with cladribine or fludarabine (DAC-7 + DAF-7, n=65 ). Consolidation included one course of high-dose AraC + mitoxantrone and one course of high-dose AraC +/- purine analogues. A median age was 45(17-58) years and 48(20-60) years for patients treated with and without purine analogues, respectively. Results: The frequency of neutropenic fever as well as microbiologically documented bacterial, fungal and viral infections during induction and consolidation did not differ between two compared groups - receiving or not purine analogues. Time to infection occurrence and infection duration were similar in both study groups. During induction and both consolidation treatments significant lower values of lymphocytosis were observed in the group of patients treated with purine analogues. There was a slight tendency to increased rate of mucositis for patients treated with purine analogues (60% vs. 44.3%, p=0.07) during induction treatment, while infections affecting skin and soft tissues were significant frequent for patients treated without purine analogues (43.3% vs. 18%, p=0.03) during second consolidation treatment (high dose AraC). The usage of intravenous anti-infectious medications (antibiotics, antifungal, antiviral) and periods of hospitalization did not differ between two groups in this study. Conclusions: We conclude that the use of purine analogues, either cladribine or fludarabine along with conventional induction and consolidation therapy does not aggreviate infectious complications in adults with AML. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 132 Late relapse in acute myeloid leukemia (AML) has been infrequently studied and variably defined in the literature. Two series have shown that late relapse of AML ≥5 years after first complete remission (CR1) is uncommon, with rates of 1.19–3% (Medeiros et al, Leuk Lymphoma 2007; Verma et al, Leuk Lymphoma 2010). We searched the long-term data available on 784 adults (<60 years-old) who were treated on 1 of 4 ECOG clinical trials (E3483, PC486, E3489, or E1900) and achieved CR1 for reports of late relapse (defined as recurrence of AML ≥3 years after CR1). Median follow-up for the 553 patients last known alive was 11.1 years. The longest median follow-up was 17.2 years on trial PC486. Outcomes We found that 11 patients (1.4%) relapsed late; of these, 2 were treated on E3483, 1 on PC486, 5 on E3489, and 3 on E1900. Seven patients with late relapse died from their disease and 4 were living at last known follow-up. Only 1 patient (0.13%) had recurrence of AML ≥5 years after achieving CR1. It is possible that more late relapses will occur on E1900 (a more recent study with ongoing follow-up). All of these trials except E3483 treated some patients with autologous hematopoietic cell transplantation (autoHCT) as part of post remission therapy. On PC486, no post remission consolidation chemotherapy was administered before autoHCT. Ninety-eight total patients on E3489 and PC486 received autoHCT, and there were no late relapses; on E1900, 2 of the 141 patients treated with autoHCT developed late relapse. No patients who underwent allogeneic (allo) HCT in CR1 experienced late relapse on any of the 4 clinical trials. Nine of the 11 patients with late relapse did not undergo HCT; of these, 5 were consolidated with high-dose cytarabine, 2 received maintenance with low-dose cytarabine and 6-thioguanine, and 2 received unknown post remission therapy. Of the 3 patients with late relapse on E1900, 2 received standard-dose and 1 high-dose daunorubicin with induction. Conclusions Across all 4 trials, only 2 of the 239 patients (0.8%) treated with post remission autoHCT experienced late relapse of AML (≥3 years after CR1), which reinforces previously published data that late relapse after autoHCT is uncommon (Cassileth et al, J Clin Oncol 1993). Furthermore, of the 35 patients treated with autoHCT on PC486, 11 relapsed early and no patients relapsed late, suggesting that post remission chemotherapy may not be necessary before autoHCT. Based on this large AML cohort of nearly 800 patients with long-term follow-up, patients who remain in CCR for at least 3 years have a very low risk of relapse and can be considered cured of their disease. Moreover, given that recurrent AML was extremely rare after 5 years or more of CCR (<0.2%), the risk of therapy-related AML from contemporary induction and post remission strategies including HCT appears to be minimal. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 3602 Background: AML in elderly patients is associated with very poor prognosis. The best treatment option for this group of patients is not established, yet. The intensity of treatment depends on performance status and comorbidities. The previous PALG AML study showed that addition of cladribine (2CdA) to conventional induction therapy; especially in patients above 40 yrs, is associated with better outcome (Ho3owiecki 2004). Based on this observation we designed a study addressed to newly diagnosed AML patients above 60 yrs old, who were fit enough to intensive treatment. Aim: To verify whether addition of 2CdA has an impact to clinical outcome in newly diagnosed AML patients older than 60 years old. Methods: From October 2004 to November 2011, 178 patients from 16 hematological PALG centers were randomly assigned to DA induction therapy consisting of daunorubicine (DNR) 45mg/m2, intravenously (iv), day 1–3 and cytarabine (AraC) 100 mg/m2, iv, day 1–7 (DA) or DA with addition of 2CdA 5mg/m2, iv, day 1–5 (DAC). Patients, who achieved complete remission (CR), received one course of consolidation with mitoxantron 6mg/m2 iv day1–2 and AraC 100mg/m2 iv day 1–5, followed by six cycles of maintenance consisting of (DNR 30mg/m2 iv day 1–2 with AraC 100mg/m2 sc day 1–5 and tioguanine 100mg/m2, p.o., twice day, day 1–5 with AraC 100mg/m2 s.c. day 1–5, alternately). Response criteria were determined according to revised recommendations of the International Working Group for Diagnosis, Standardization of Response Criteria, Treatment Outcomes, and Reporting Standards for Therapeutic Trials in Acute Myeloid Leukemia (Chesson 2003). Statistical analysis: Pairwise comparisons between patient characteristics were performed by the Mann-Whitney U-test for continuous variables and by χ2-statistics or Fisher's exact test for categorical variable. The Kaplan-Meier estimates of survival were calculated and compared using the log-rank test. For multivariate analysis, the Cox proportional hazard regression model was applied. P values < 0.05 were considered significant. Results: 88 pts with median age 66 yrs (range 60–79 yrs) were randomized to DA and 90 pts with median age 64 yrs (range 60–79 yrs) was enrolled to DAC schema. The both groups were comparable in terms of age, sex, performance status, white blood cell count, hemoglobin level, platelets count, tumor burden parameters, cytogenetic, between the both groups. The overall CR rate was 38%. In DA and DAC groups CR was achieved in 33% and 43% pts, respectively (p=0.12). However, in patients under 65 yrs the trend towards higher CR rate in DAC arm than DA group was observed (47% vs. 29%, p=0.09). In pts above 65 yrs the CR rate was comparable (39% vs. 38%, p=0.8). The efficacy and hematological toxicity in DA and DAC groups was similar (Table 1). Also no statistical significant differences in non-hematological toxicity were observed (data not shown). Early deaths in DA and DAC did not differ significantly. Median overall survival (OS) in DA and DAC arm was also similar in both groups (Table 1). In proportional hazard Cox analysis only age under 65yo, CR achievement and WBC above 100G/L were important for better OS (p=0.02, p<0.001 and p=0.09). The presence of dysplastic changes, karyotype, LDH, number of bone marrow blasts did not influenced OS. Conclusions: Our data suggest that prolonged overall survival can be achieved in elderly AML patients mainly till 65yrs. Intensive therapy, especially in patients older than 65yrs, may be associated with high number of complications what results withdrawing from intensive treatment protocol. Hematological and non-hematological toxicity of DA and DAC schema is comparable, however higher CR rate in DAC group in patient till 65yrs may suggest, that addition of 2CdA to DA does not increase toxicity and may be a treatment option in this patient population.

e18509 Background: Patients with acute myeloid leukemia (AML) who achieve complete remission with induction therapy require consolidation therapy. The standard of care consolidation is HIDAC or IDAC depending on age and risk stratification. Consolidation therapy has historically been administered in the inpatient setting. The rising cost of AML care has prompted institutions to consider shifting therapy to the outpatient setting. However, the safety and feasibility of outpatient HIDAC/IDAC consolidation therapy has not been established. Moffitt Cancer Center (MCC) developed an Inpatient/Outpatient (IPOP) program to facilitate administration of complicated regimens in the outpatient setting. We hypothesized that IPOP administration of HIDAC/IDAC consolidation therapy is safe and may have cost-savings implications. Methods: We conducted a retrospective chart review on AML patients who were 18 years or older and received HIDAC/IDAC consolidation therapy at MCC following induction therapy from January 1, 2015 to November 1, 2018. Data collected included age, risk stratification, treatment history, clinic visits, number of cycles received in the IPOP versus inpatient setting, supportive care, hospitalizations, and chemotherapy related adverse events. Results: 258 of 270 cycles of HIDAC/IDAC were delivered outpatient over the reviewed time period to 122 patients. 45 patients (37%) required hospitalization during consolidation with the primary reason being neutropenic fever (72%), consistent with historical data (50 to 90%). No patients receiving outpatient consolidation required hospitalization during chemotherapy. Specific details regarding administration of HIDAC/IDAC in IPOP, including infusion times, frequency of visits, laboratory frequency, supportive medications, and home antimicrobials will be reported. 1,290 hospital days were saved through IPOP administration. Financial assessment of cost-savings is being determined and will be reported. Conclusions: Outpatient administration of HIDAC/IDAC consolidation therapy for AML is a safe option for AML patients undergoing consolidation.

Abstract We conducted a multi-institutional randomized study to determine whether high-dose daunorubicin would be as effective as standard-dose idarubicin in remission-induction therapy for newly diagnosed adult patients younger than 65 years of age with acute myeloid leukemia. Of 1064 patients registered, 1057 were evaluable. They were randomly assigned to receive either daunorubicin (50 mg/m2 daily for 5 days) or idarubicin (12 mg/m2 daily for 3 days) in combination with 100 mg/m2 of cytarabine by continuous infusion daily for 7 days as induction therapy. Complete remission was achieved in 407 (77.5%) of 525 patients in the daunorubicin group and 416 (78.2%) of 532 in the idarubicin group (P = .79). Patients achieving complete remission received intensive postremission therapy that consisted of either 3 courses of high-dose cytarabine or 4 courses of standard-dose therapy. Overall survival rates at 5 years were 48% for the daunorubicin group and 48% for the idarubicin group (P = .54), and relapse-free survival rates at 5 years were 41% and 41% (P = .97), respectively. Thus, high-dose daunorubicin and standard-dose idarubicin were equally effective for the treatment of adult acute myeloid leukemia, achieving a high rate of complete remission and good long-term efficacy.
