Dreher M, et al. - Researchers determined the prevalence of sleep-disordered breathing (SDB) using a two-channel screening system (ApneaLink) among patients with newly-diagnosed lung cancer from three centers in Germany. SDB was defined as an apnea-hypopnea index of > 5/h. Based on apnea-hypopnea index (AHI), SDB was classified as mild (AHI 5–15/h) or severe (AHI ≥15/h). They used the Epworth Sleepiness Scale (ESS) and the Pittsburgh Sleep Quality Index (PSQI) to evaluate the presence of SDB-related symptoms. Study included a total of 100 patients. They found that among patients with newly-diagnosed lung cancer, SDB prevalence was high. In these patients, SDB was found to be related to intermittent hypoxia and increased daytime sleepiness.
