Abstract
BACKGROUND/OBJECTIVE
Acute myeloid leukemia (AML) is the most common acute leukemia in adults. We documented the characteristics and results of treatment of patients with AML at a single reference center.
METHODS
Patients diagnosed with AML between June 2003 and July 2011 at a university hospital in northeast Mexico were studied. Overall survival (OS) and event-free survival (EFS) were determined, and risk factors were analyzed with respect to their influence on prognosis.
RESULTS
A total of 132 AML patients were included. Median age was 32 years. Complete remission (CR) was achieved by 55% of patients. CR was achieved by 65.1% of patients <60 years (n = 109), compared to 8.7% of those >60 years (n = 23; p < 0.001). In all, 39% of patients >60 years suffered an early death, compared to 14.7% of those <60 years (p < 0.001). OS for patients with AML was 35%, whereas EFS was 32%. On multivariate analysis, patients >60 years had a lower OS and EFS (p < 0.001). A total of 28% of patients received a transplant, and they had high er OS and EFS. Conclusions: Our patients were considerably younger and had remarkably lower survival rates than reported for other populations; those >60 years had a higher early death rate, and fewer of these patients achieved CR.
