Abstract Background Elderly patients with acute myeloid leukemia (AML) has generally poor prognosis prognosis in accordance with their unfavorable clinical and biologic features. Hypomethylating agents have shown potential in the treatment of AML as well as myelodysplastic syndrome (MDS). In this retrospective study, we compared the outcomes of elderly AML patients according to induction treatment options: decitabine versus intensive chemotherapy. We also tried to identify specific subsets of patients who are most likely to benefit from decitabine or intensive chemotherapy. Methods This study included elderly patients aged 65 years or older who received induction treatment with decitabine or intensive chemotherapy for newly diagnosed AML at a single institute. The endpoints for this study were overall survival (OS), response, and event-free survival (EFS). Response included complete remission (CR), CR with incomplete hematologic recovery (CRi), and CR with partial hematologic recovery (CRh). Results A total of 107 patients, decitabine for 75 and intensive chemotherapy for 32, were analyzed. Decitabine was given as 20 mg/m2/day for 5 days every 4 weeks. Median 5 courses (range, 1-43) were delivered to the patients and 16 patients were still on decitabine treatment at the time of analysis. Intensive chemotherapy regimens included cytarabine plus daunoruribin (n=21) or idarubicin (n=10), and hyper-CVAD (n=1): 25 patients received one course and 7 received two courses for induction treatment. The rate for CR + CRi + CRh (CRR) was 38.6% (39 of 101 assessable patients). With a median follow-up duration of 14.8 months (95% confidence interval [CI], 12.0-22.8) among surviving patients, 79 patients died and 22 relapsed. The median OS and EFS were 12.3 months (95% CI, 10.0-14.7) and 4.1 months (95% CI, 2.5-5.7), respectively. Decitabine showed lower CRR (26.1% vs. 65.6, P<0.001) with similar EFS (median 3.4 vs. 6.1 months, P=.338) and OS (median 11.0 vs. 14.8 months, P=.124) compared to intensive chemotherapy (Figure 1). Multivariate analysis demonstrated that induction treatment option, peripheral blood (PB) blast percentage, and leukemia type (secondary vs. de novo) were independent risk factors for CRR. A presence of FLT3-ITD mutation, complex karyotype, and higher PB blast percentage were independently associated with shorter OS. Subgroup analysis for OS showed that intensive chemotherapy was superior to decitabine in patients with FLT3-ITD mutation (median 9.5 vs. 2.6 months, P=.025) and poor cytogenetic risk (10.8 vs. 6.1 months, P=.027), but decitabine showed tendency towards a longer OS compared to intensive chemotherapy in those with monosomy 7 or del(7q) (11.7 vs. 3.3 months, P=.093; Figure 2). Conclusion Decitabine showed similar OS to intensive chemotherapy despite of lower response rate in elderly AML patients. Clinical outcomes of specific subgroups seemed to be different according to induction treatment options. Further studies are warranted for selection of optimal treatment options for elderly AML patients. Disclosures No relevant conflicts of interest to declare.

Midostaurin is a tyrosine multikinase inhibitor approved for the treatment of patients with newly diagnosed acute myeloid leukemia (AML) with mutated Fms-like tyrosine kinase-3. We describe a case report of a 49-year-old AML patient treated with an intensive chemotherapy regimen followed by midostaurin. After achieving complete remission with blood count recovery, he suffered from a serious, rare complication of necrotizing hemorrhagic gastritis with no evidence of infection or malignant infiltration, possibly associated with midostaurin therapy.

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.

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.
