Abstract
We sought to predict treatment responses and outcomes in older patients with newly diagnosed acute myeloid leukemia (AML) from our FLUGAZA phase III clinical trial (PETHEMA group) based on mutational status, comparing azacytidine (AZA) with fludarabine plus low-dose cytarabine (FLUGA). Mutational profiling using a custom 43-gene next-generation sequencing panel revealed differences in profiles between older and younger patients, and several prognostic markers that were useful in young patients were ineffective in older patients. We examined the associations between variables and overall responses at the end of the third cycle. Patients with mutated DNMT3A or EZH2 were shown to benefit from azacytidine in the treatment-adjusted subgroup analysis. An analysis of the associations with tumor burden using variant allele frequency (VAF) quantification showed that a higher overall response was associated with an increase in TET2 VAF (odds ratio (OR), 1.014; p = 0.030) and lower TP53 VAF (OR, 0.981; p = 0.003). In the treatment-adjusted multivariate survival analyses, only the NRAS (hazard ratio (HR), 1.9, p = 0.005) and TP53 (HR, 2.6, p = 9.8 × 10-7) variants were associated with shorter overall survival (OS), whereas only mutated BCOR (HR, 3.6, p = 0.0003) was associated with a shorter relapse-free survival (RFS). Subgroup analyses of OS according to biological and genomic characteristics showed that patients with low-intermediate cytogenetic risk (HR, 1.51, p = 0.045) and mutated NRAS (HR, 3.66, p = 0.047) benefited from azacytidine therapy. In the subgroup analyses, patients with mutated TP53 (HR, 4.71, p = 0.009) showed a better RFS in the azacytidine arm. In conclusion, differential mutational profiling might anticipate the outcomes of first-line treatment choices (AZA or FLUGA) in older patients with AML. The study is registered at ClinicalTrials.gov as NCT02319135.

Abstract
BACKGROUND Infection is still a frequent cause of morbidity and mortality in acute myelogenous leukemia (AML) patients receiving chemotherapy. Recently the main cause of infection has changed from gram-negative to gram-positive bacteria and the resistance to antibiotics has increased. This study aimed to access the effectiveness of antimicrobial prophylaxis (AP) with orally absorbable antibiotics. METHODS Ninety-five AML patients receiving chemotherapy at Catholic Hemopoietic Stem Cell Transplantation Center from March 1999 to July 1999 were randomly divided into the AP group (250 mg ciprofloxacin twice a day, 150 mg roxithromycin twice a day, 50 mg fluconazole once a day) and the control group for a prospective analysis. RESULTS The incidence of fever was 82.6% in the AP group and 91.6% in the control group (p = 0.15). Though classification and sites of infections showed no difference between the two groups, the catheter associated infection occurred more frequently in the AP group in significance. The time interval between initiation of chemotherapy and onset of fever, white blood cell (WBC) count at the onset of fever, duration of leukopenia (WBC < 1,000/mm3), duration of systemic antibiotic therapy, mortality due to infection and hospitalization period from the data starting chemotherapy showed no differences between the two groups. Infections due to gram negative bacteria decreased to 33.3% in the AP group (vs. 92% in the control group), but infections due to gram positive bacteria increased to 66.7% (vs. 8% in the control group). Gram negative bacteria showed 100% resistance to ciprofloxacin in the AP group and gram-positive bacteria showed 90-100% resistance to erythromycin, regardless of the presence of AP. CONCLUSION The AP could not reduce the occurrence of infection or infection associated death in AML patients receiving chemotherapy. On considering increased gram-positive infection and resistance to fluoroquinolone and macrolide, routine prescription of AP should be reconsidered. Further studies that assess the effectiveness of AP in other malignancies, aplastic anemia and bone marrow transplantation are required.
