Abstract

We assessed in a French regional healthcare network the distribution of treatments, prognostic factors, and outcome of 334 newly diagnosed acute myeloid leukemia patients aged 60 years or older over a 4-year period of time (2007-2010). Patients were selected in daily practice for intensive chemotherapy (n = 115), azacitidine (n = 95), or best supportive care (n = 124). In these three groups, median overall survival was 18.9, 11.3, and 1.8 months, respectively. In the azacitidine group, multivariate analysis showed that overall survival was negatively impacted by higher age (P = 0.010 for one unit increase), unfavorable cytogenetics (P = 0.001), lymphocyte count <0.5 G/L (P = 0.015), and higher lactate dehydrogenase level (P = 0.005 for one unit increase). We compared the survival of patients treated by azacitidine versus intensive chemotherapy and best supportive care using time-dependent analysis and propensity score matching. Patients treated by intensive chemotherapy had a better overall survival compared with those treated by azacitidine from 6 months after diagnosis, whereas patients treated by azacitidine had a better overall survival compared with those treated by best supportive care from 1 day after diagnosis. This study of "real life" practice shows that there is a room for low intensive therapies such as azacitidine in selected elderly acute myeloid leukemia patients.
