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.

Abstract Context.—The clinical association between loss of the Y chromosome and acute myelogenous leukemia and myelodysplastic syndrome (AML/MDS) has been debated because both phenomena are related to aging. A prior publication suggests that loss of the Y chromosome in more than 75% of cells may indicate a clonal phenomenon that could be a marker for hematologic disease. Objective.—To evaluate the relationship between loss of the Y chromosome and AML/MDS. Design.—A retrospective review of cytogenetic reports of 2896 male patients ascertained from 1996 to 2007 was performed. Results were stratified based on the percentage of cells missing the Y chromosome and were correlated with patients' ages and bone marrow biopsy reports through logistic regression analysis with adjustment for age. Results.—Loss of the Y chromosome was found in 142 patients. Of these, 16 patients demonstrated myeloid disease, with 2 cases of AML and 14 cases of MDS. An increased incidence (P < .05) of AML/MDS was seen only in the group composed of 8 patients with complete loss of the Y chromosome in all karyotyped cells (1 case of AML and 7 cases of MDS). Conclusion.—Loss of the Y chromosome appears to be primarily an age-related phenomenon. However, in individuals in which all cells on cytogenetic analysis showed loss of the Y chromosome, there was a statistically significant increase in AML/MDS, suggesting that the absence of any normal-dividing cells in a bone marrow analysis may be indicative of AML/MDS.
