INTRODUCTION: To the best of our knowledge, few studies have addressed the prognosis of patients with acute myeloid leukemia (AML) in Saudi Arabia. The present study retrospectively analyzed the prognostic factors in patients with de novo AML at a single institution owing to the observation of some differences with the reported data from the Western world.

PATIENTS AND METHODS: Patients with de novo AML who had been referred to King Abdulla Medical City were included. All patients had undergone bone marrow aspiration, biopsy, flow cytometry, cytogenetics (conventional and fluorescence in situ hybridization panel performed at Mayo Clinic), molecular tests, and other routine tests.

RESULTS: The data from 170 patients were reviewed. Of the 170 patients, 26 had had acute promyelocytic leukemia, 16 with AML had received less intensive therapy, 119 had received intensive induction, and 8 had refused treatment. The present analysis was limited to the 119 patients who had received intensive induction therapy. For the major cytogenetic categories, 17 of 27 patients with core binding factor leukemia (62.9%) were reassigned to the intermediate (n = 10; 37%) or unfavorable (n = 7; 25.9%) risk group according to the FLT3-ITD and NPM results. Of the 50 cases of normal cytogenetic findings, 2 (4%) were considered unfavorable, 12 (24%), favorable, 30 intermediate (60%), and 6 (12%) unknown. The median leukemia-free survival was 21.5 months. The median overall survival was 16.4 ± 2.2 months, with a 3-year survival rate of 37.2%. Multivariate Cox regression analysis revealed that the cytogenetics results (P = .002) and the presence of FLT-3 (P = .03) were independent prognostic factors for relapse-free survival. Performance status, response, relapse, and cytogenetics findings were independent prognostic factors for survival.

CONCLUSIONS: The results from the present study revealed some differences in patient age and cytogenetic risk groups for patients with AML in our region and those in the Western world, including a younger median age, relevance of core binding factor leukemia, and a greater incidence of monosomies.
