BACKGROUND: Among the subtypes of acute myeloid leukemia, acute promyelocytic leukemia (APL) is a distinctive one. There are no published data regarding APL in Kurdistan, Iraq, so the data on this disease is limited. OBJECTIVES: The aims of this study was to recognize the epidemiology, clinical presentation, and to find out the outcome among APL patients at Nanakali hospital in Erbil city. PATIENTS AND METHODS: This was a retrospective study performed at Nanakali Hospital for blood diseases and cancer, Erbil, Iraq. Patients older than 18 years diagnosed with APL from January 2007 to December 2016 were involved in the study. Chi-square test, Kaplan–Meier survival curves, and the Log-Rank (Mantel–Cox) test were used for data analysis. RESULTS: During the period of the study, APL was diagnosed in 90 patients. The mean age (± standard deviations) was 37.5 ± 15.5 years, and the median was 35.5 years, the male: female ratio was 1.3:1. Around 70% were living in urban areas. Regarding clinical presentations: 71.4% of the patients presented with generalized weakness, 64.44% with bleeding, 48.9% with fever, and 2.2% presented with thrombosis. The mean hemoglobin was 8.31 ± 2.69 g/dL, mean white blood cell count of 22.3 ± 29.4 × 109/L, and mean platelet count was 33.37 ± 27.5 × 109/L. The complete remission rate was 68.2%. Early death rate was 46.4% and the 5-year survival rate was 37.8%. CONCLUSION: The clinical and epidemiological features were compared with previously published studies. High-risk patients predominate in our study population. There was a significant association between the overall survival and risk score.
