Abstract Elderly patients aged 65 or older with acute myeloid leukemia (AML) have poor prognosis. The risk stratification based on genetic alteration has been proposed in national comprehensive cancer network (NCCN) guideline but its efficacy was not well verified especially in real world elderly patients. The nutritional status assessment using controlling nutritional status (CONUT) score is a prognostic biomarker in elderly patients with solid tumors but was not examined in elderly AML patients. We performed prospective analysis of genetic alterations of 174 patients aged 65 or older with newly diagnosed AML treated without hematopoietic stem cell transplantation (HSCT) and developed simplified CONUT (sCONUT) score by eliminating total lymphocyte count from the items to adapt AML patients. In this cohort, both the NCCN 2017 risk group and sCONUT score successfully stratified the overall survival (OS) of the elderly patients. A multivariable analysis demonstrated that adverse group in NCCN 2017 and high sCONUT score were independently associated with poor 2-year OS. Both risk stratification based on NCCN 2017 and sCONUT score predict prognosis in the elderly patients with newly diagnosed AML.

Introduction. Elderly patients aged 65 or older with acute myeloid leukemia (AML) are often ineligible for hematopoietic stem cell transplantation (HSCT) and generally have a poor prognosis. The prognostic risk classification based on NCCN Guidelines Version3. 2017; NCCN 2017 (O'Donnell MR, JNCCN. 2017) is widely performed; however, the impact of this classification on the prognosis of such elderly AML patients is unclear. While nutritional status assessment using controlling nutritional status (CONUT score) based on serum level of albumin (Alb), total-cholesterol (T-chol) and total lymphocyte count (TLC) predicts prognosis of elderly patients with solid tumor (Liu X, BMC Cancer. 2018), the prognostic significance of nutritional status in elderly patients with AML remains to be clarified. Methods. Hokkaido Leukemia Net (HLN) is prospective cohort study collecting AML samples from hospitals of North Japan Hematology Study Group (NJHSG). In this study, we focused on newly diagnosed AML patients aged 65 or older treated without HSCT, and investigated cytogenetic and molecular abnormality of leukemic cells including FLT3-ITD, NPM1, CEBPA, and KIT. We stratified the patients into favorable, intermediate, and adverse risk group based on NCCN 2017. In order to adjust the assessment of nutritional status for hematopoietic malignancy, we modified the CONUT score eliminating TLC from evaluation criteria (modified-CONUT score, Table) and defined patients with score 3 or more at diagnosis as high group. We evaluated the impacts of NCCN 2017 and modified-CONUT scores on overall survival (OS) in these patients. The study procedures were in accordance with the Helsinki Declaration and institutional ethical guidelines, conducted under the auspices of the institutional ethics committee, and approved by the institutional review boards. Results. Overall, 181 patients with newly diagnosed AML patients aged 65 or older enrolled in HLN between April 2010 and March 2018. Seven patients undergone HSCT were excluded and 174 patients were reviewed (Age 65-93, median 71; male 104, female 70). In this cohort, classification based on NCCN 2017 successfully divided the prognosis of the patients for 2-year and 5-year OS [2-year OS; favorable group, 59.9%; intermediate group, 43.8%; adverse group, 8.1%, 5-year OS; favorable group, 41.5%, intermediate group, 19.7%; adverse group, 4.1%, P=0.00258, Figure A]. On 112 patients who had available records of serum Alb levels and T-chol levels at diagnosis, OS in patients with high modified-CONUT score was significantly lower than the low score group [2-year OS; low score group, 50.3%; high score group, 18.5%; 5-year OS; low score group, 23.5%; high score group, 9.24%, P=0.00203, Figure B]. In a univariate analysis, adverse group in NCCN 2017 and high modified-CONUT score were associated with poor 2-year OS. A multivariate analysis demonstrated that　adverse group in NCCN 2017 and high modified-CONUT score were independently associated with poor 2-year OS (adverse group in NCCN 2017; HR, 2.464 ; 95% CI, 1.514 to 4.012, P=0.0002854, high modified-CONUT score; HR, 1.664 ; 95% CI, 1.051 to 2.635, P=0.02976; log-rank). Altogether, we demonstrated that risk stratification based on NCCN 2017 and modified-CONUT score are both effective for predicting prognosis in elderly patients with newly diagnosed AML. Conclusion. The prognostic risk classification based on AML disease status using NCCN Guidelines 2017 effectively stratify prognosis of elderly patients with AML. Moreover, new assessment scoring of patients' nutrition status based on modified-CONUT score can easily stratify elderly patients with newly diagnosed AML.

Abstract Introduction Risk-stratification of patients with acute myeloid leukemia (AML) can not only improve treatment response, but also reduce side effects of the treatment, especially in the elderly. A number of patient-specific and leukemia-associated factors are related to the poor outcome in older patients with AML. However, comprehensive studies regarding the impact of genetic alterations in this group of patients are limited. Methods and Materials A total of 500 adult patients with newly diagnosed de novo AML who had enough bone marrow cryopreserved cells for analysis at the National Taiwan University Hospital were enrolled consecutively. We compared the clinico-biological features, cytogenetics and molecular gene mutations between patients aged 60 years or older (n=185) and those younger (<60 years, n=315). Result Among older patients, those received standard intensive chemotherapy had a longer overall survival (OS) than those treated with palliative care. Compared with younger patients, the elderly had a higher incidence of poor-risk cytogenetic changes, but a lower frequency of favorable-risk cytogenetics. The median number of molecular gene mutations at diagnosis was higher in the elderly than the younger. Older patients had significantly higher incidences of PTPN11, NPM1, RUNX1, ASXL1, TET2, DNMT3A, and P53 mutations but a lower frequency of WT1 mutations. In multivariate analysis for OS among the elderly who received standard intensive chemotherapy, high WBC >50,000/μL at diagnosis, RUNX1 mutations, DNMT3A mutations, and P53 mutations were independent worse prognostic factors, while the presence of NPM1 mutations in the abcence of FLT3/ITD mutations was an independent good prognostic factor. The frequency of acquiring one or more adverse genetic alterations was much higher in older patients than younger ones. Further, the pattern of gene mutations could divide older patients with intermediate cytogenetics into three groups with significantly different complete remission rates, OS, and disease-free survival. Conclusion Older AML patients frequently harbored high-risk cytogenetics and gene mutations, and had poorer prognosis. Integration of cytogenetics and molecular alterations could risk-stratify older patients into groups with significant different outcomes. For those patients with poor prognosis under current chemotherapy, novel therapies, such as demethylating agents or other targeted therapies may be indicated.

BACKGROUND: The runt-related transcription factor family (RUNXs) including RUNX1, RUNX2, and RUNX3 are key transcriptional regulators in normal hematopoiesis. RUNXs dysregulations caused by aberrant expression or mutation are frequently seen in various human cancers especially in acute myeloid leukemia (AML). OBJECTIVE: We systemically analyzed the expression of RUNXs and their relationship with clinic-pathological features and prognosis in AML patients. METHODS: Expression of RUNXs was analyzed between AML patients and normal controls from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) projects. Correlations between RUNXs expression and clinical features together with survival were further analyzed. RESULTS: All RUNXs expression in AML patients was significantly increased as compared with controls. RUNXs expression was found to be significantly associated with genetic abnormalities such as RUNX1 mutation, t(8;21) and inv(16)/t(16;16). By Kaplan-Meier analysis, only RUNX3 overexpression was associated with shorter overall survival (OS) and disease-free survival (DFS) among non-M3 AML patients. Notably, in high RUNX3 expression groups, patients received hematopoietic stem cell transplantation (HSCT) had markedly better OS and DFS than patients without HSCT among both all AML and non-M3 AML. In low RUNX3 expression groups, there were no significant differences in OS and DFS between HSCT and non-HSCT groups among both all AML and non-M3 AML. In addition, a total of 835 differentially expressed genes and 69 differentially expressed microRNAs were identified to be correlated with RUNX3 expression in AML. CONCLUSION: RUNXs overexpression was a frequent event in AML, and was closely associated with diverse genetic alterations. Moreover, RUNX3 expression may be associated with clinical outcome, and helpful for guiding treatment choice between HSCT and chemotherapy in AML.

Abstract The failure to overcome drug resistance leads to a high rate of relapse in elderly patients with acute myeloid leukemia. We evaluated, in a Phase I study the feasibility of a dose dense regimen of HiDAC, and MylotargTM therapy for newly diagnosed elderly (≥60 years) patients with AML in terms of toxicity with two cycles of this regimen as the sole induction and consolidation therapy. HiDAC was administered in a dose escalation pattern: 3000mg/m2 intravenously given for 6, and 9 doses, and MylotargTM was administered at a dose of 6mg/m2 intravenously on days 1 and 8 of each cycle. Patients without unacceptable toxicity, defined as failure to recover counts to a minimum of ANC ≥ 500/ μl, platelets ≥ 30K and hematocrit ≥ 25%, received a second cycle of therapy, though not before day 28 following day 1 of induction. In addition, death within the first 30 days of induction (not related to disease progression) and life-threatening non-hematologic toxicity (such as cardiac or pulmonary arrest) was also considered dose-limiting. Patients with persistent disease but at least a 50% decrease in the marrow or peripheral blood blast count, or those with low blood counts and patients achieving CR without platelet recovery (CRp) at the 4–6 week examination received cycle 2 with a de-escalation of the Mylotarg dose (from 6 mg/m2 to 4 mg/m2). All patients received G-CSF 5mcg/kg/day subcutaneously from days 11–14. Eight patients (five male, three female) with a median age of 68 years (range 60–74) were enrolled. In cohort one (6 doses of HiDAC), four of six patients were able to complete both cycles of therapy and two of these have achieved CR. Two of the six patients achieved CRp with persistent thrombocytopenia and thus received a second cycle of chemotherapy off protocol. One patient in this cohort had progressive disease and persistent pancytopenia requiring transfusions and subsequently received chemotherapy using Etoposide and Cyclophosphamide. Five out of six patients are alive and remain disease free. In cohort two (9 doses of HiDAC), two patients have been enrolled thus far. One patient developed neurotoxicity after six doses of HiDAC and thus completed both cycles of therapy with six doses of HiDAC along with protocol dose of MylotargTM. The other patient was able to get all nine doses of HiDAC and both patients have achieved a CR. No unexpected hematologic toxicity was observed. All patients developed grade IV thrombocytopenia requiring platelet transfusions. One patient in cohort one died after developing aspergillus infection and multiorgan failure before he could be evaluated for response. Two patients in cohort one developed uncomplicated gram-positive bacteremia requiring antibiotics. In cohort two, one patient developed neurotoxicity and the other developed uncomplicated gram-positive bacteremia. At the time of submission of this abstract seven out of eight patients are alive with four CR and two CRp. No veno-occlusive disease was seen in these eight patients treated with two cycles of HiDAC and MylotargTM back to back. The high rate of CR and relatively good tolerance of this regimen remains encouraging.

Abstract Abstract 1981 Background: Gene mutations may serve as potential markers to extend the prognostic parameters in acute myeloid leukemia (AML) patients. In this study, we detected distribution of mutations in the nucleophosmin gene (NPM1), C-KIT, the fms-related tyrosine kinase 3 gene (FLT3), Isocitrate dehydrogenase gene 1 and 2 (IDH1, IDH2), the neuroblastoma RAS viral oncogene homolog (NRAS) and DNA methyltransferase 3A gene (DNMT3A) in 442 newly diagnosed AML patients (none-APL). Associations of gene mutations with clinical outcomes in these patients followed HSCT treatment or chemotherapy were further evaluated. Methods: Between February 2005 and December 2011, 442 newly diagnosed AML (none-APL) patients in our centre were retrospectively analyzed. There are 248 males and 194 females, and the median ages were 40 (16–60) years. 393 patients (88.9%) of patients were with single or normal karyotype and 49 patients (11.1%) were with complex abnormal karyotype. In addition to MICM examination, direct sequencing was employed to access the distribution of mutations in of FLT3-ITD (exon14), FLT3-TKD (exon 20), NPM1 (exon12), C-KIT (exon8, 17), IDH2 (exon 4), NRAS (exon1, 2), DNMT3A (exon23) of 445 AML patients. Complete remission (CR) was achieved in 258 patients (58.4%) followed the standard induction therapy, 128 patients received HSCT (Allo-HSCT: 121 vs. Auto-HSCT: 7) therapy after first remission or second remission while 258 patients received consolidation chemotherapy contained 4–6 cycles high dose Ara-C (HD-Ara-C). Overall survival (OS) and Event-free survival (EFS) were measured at last follow-up (censored), and Kaplan-Meier analysis was used to calculate the distribution of OS and EFS. Results: In 442 AML (None-APL) patients, 44 patients (9.7%) had C-KIT mutations, 97 patients (21.9%) had NPM1 mutations, 95 patients (21.5%) had FLT3-ITD mutations, 26 patients (5.9%) had FLT3-TKD mutations, 23 patients (5.2%) had IDH1 mutations, 48 patients (10.9%) had IDH2 mutations, 31 patients (7.0%) had DNMT3A mutations, and 40 patients (9.0%) had NRAS mutations. Using COX regression, we found that mutations in FLT3-ITD (HR:2.113; 95%CI: 1.1420 to 3.144),IDH1 (HR:3.023; 95%CI: 1.055 to 3.879), NRAS (HR:1.881; 95%CI: 1.021 to 2.945), and DNMT3A (HR: 2.394; 95%CI: 1.328 to 4.315) were independent unfavorable prognostic indicators of overall survival of AML patients. We further compared the outcomes of AML patients with such gene mutations followed different therapy (HSCT vs. HD Ara-C), and results shown that patients with mutations in IDH1, NRAS and DNMT3A received HSCT therapy had better survival. The median OS and EFS of patients with FLT3-ITD, IDH1, NRAS and DNMT3A in the two groups (HSCT vs. HD Ara-C) were as follows: IDH1 (OS: 35 months vs. 11 months, p=0.016; EFS: 34 months vs. 8 months, p=0.012), NRAS (OS: 27months vs. 8 months, p=0.008; EFS: 23 months vs. 4 months, p=0.049), DNMT3A (OS: 66 months vs. 19 months, p=0.008; EFS: 54 months vs. 13 months, p=0.002). Conclusions: Taken together, our data proved that mutant FLT3-ITD, IDH1, NRAS, and DNMT3A might serve as poor prognostic markers and hematopoietic stem cell transplantation as first-line treatment could favor the outcome of AML patients carrying IDH1, NRAS, and DNMT3A mutations. Disclosures: No relevant conflicts of interest to declare.

7057 Background: Almost 60% of the patients with Acute Myeloid Leukemia (AML) are over the age of 60 years. Age is one of the strongest adverse prognostic factor for AML, both for induction remission and for survival. Studies have shown that elderly patients have reduced tolerance to aggressive chemotherapy especially the myelosupressive effects. Elderly patients with Leukemia who receive intensive treatment often die as a result of chemotherapy. Aggressive chemotherapy is also costly which the relatives in developing country are reluctant to spend for the elderly patients. The aim of our study was to see the outcome, tolerability and cost effectiveness of oral chemotherapeutic agents. Methods: We selected consecutive 100 patients more than 50 years of age in haemato oncology department of NCRI (Netaji Subhas Chandra Bose Cancer Research Institute) during the period from Jan 2004 to Dec 2006. The mean age of the patients was 65 (range 50 –71) years. There was male preponderance. The inclusion criteria were performance status more than 60% (Kornofsky), Morphological, Cyto-Chemical and Immunophenotyping diagnosis of Acute Myeloid Leukemia (AML), normal liver (billirubine < 2) and kidney function ( Creatinine <2%). After the incent consent all patient were started oral chemotherapeutic agents 6 Mercptopurine (6MP) 75mg/m2. Etoposide 70mg/m2 and Prednisolone 40mg/m2. All agents are given 3 weeks followed by 7 days gap every month and continued for 6 months. Bone Marrow was repeated after 3rd & 6th course of chemotherapy. Results: Fifteen (15%) and thirtyeight patients (38%) had complete hematological response after 3rd & 6th course of chemotherapy. Seven patients (7%) died because of grade III/IV Neutropenia. Median duration of Myelosupression was 18 days (2 to 48 days).12% required hospitalisation. With median follow up of 19 months (range 2–36 months) the disease free survival (DFS) and over all survival (OS) was 18 % and 32 % respectively. Conclusions: The combination of oral chemotherapeutic agents consisting of 6MP, Etoposide & Prednisolone were well tolerated by elderly patients with good induction remission, low mortality and median survival. It was cheaper and well accepted by the patients. No significant financial relationships to disclose.
