Purpose: Prior research suggests a link between obstructive sleep apnea (OSA) and the likelihood of developing a variety of solid tumors; however, there are no studies assessing OSA and leukemia. This study is the first to identify a potential association between OSA and leukemia using data from the Korea National Health Insurance Service database.Methods: A total of 162,646 patients (≥20 years of age and without any cancer history) newly diagnosed with OSA between 2011 and 2017 were included. A control group of 813,230 subjects was selected using propensity score matching based on age and sex. The mean follow-up time was 4.4 ± 2.0 years. The primary endpoint was newly diagnosed leukemia of any type. The leukemia hazard ratio (95% confidence interval [CI]) was calculated for patients with OSA and compared with that of patients in the control group.Results: The incidence of leukemia among patients with OSA was significantly higher than that in the controls (1.35 [1.05-1.74]). The hazard ratio was the highest, 1.74 in those under 40 years, and gradually decreased with age, to 1.38 in those aged 40-65 years and 0.96 in those over 65. In particular, the incidence of lymphoid leukemia (2.06 [1.18-3.60]) was higher than that of myeloid (1.34 [1.00-1.81]) or unspecified leukemia (0.60 [0.20-1.58]).Conclusion: OSA is associated with an increased incidence of leukemia, particularly in patients younger than 40 years of age.
