Two of these drugs, azacitidine and decitabine, have received FDA approval for the treatment of MDS and chronic myelomonocytic leukemia (CMML). However, phase 2 and 3 studies that assessed these agents in MDS included only a small number of patients with CMML. The objective of this study was to evaluate the efficacy and safety of azacitidine in the treatment of CMML.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS:<\/jats:title><jats:p>The records of thirty\u2010eight patients diagnosed with CMML and treated with azacitidine at our institution were reviewed. Azacitidine was administered at 75 mg\/m<jats:sup>2<\/jats:sup>\/day for 7 days or 100 mg\/m<jats:sup>2<\/jats:sup>\/day for 5 days every 4 weeks. Patients who received at least 1 cycle of the drug were considered evaluable for response.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p>Response was assessed by the modified International Working Group (IWG) criteria. The overall response rate was 39% (14 of 36); complete response (CR) rate was 11% (4 of 36); partial response (PR) rate was 3% (1 of 36); hematologic improvement (HI) was 25% (9 of 36). The median overall survival was 12 months. There was a statistically significant overall survival advantage in responders compared with nonresponders: 15.5 months versus 9 months, respectively (<jats:italic>P<\/jats:italic> = .04). Treatment was generally well tolerated. One of 2 patients had complete resolution of a skin rash that was due to monocytic infiltration.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS:<\/jats:title><jats:p>Azacitidine is active in the treatment of CMML. The therapy\u2010associated toxicity is acceptable. Our results support further investigation of azacitidine in CMML, particularly in combination with other agents.
