Background: Episodic dyspnea (ED) is a common problem in patients with advanced lung cancer (LC). However, the prevalence of ED and other related aspects in this patient population is not known. Objectives: To assess and describe the prevalence, clinical features, treatment, and risk factors for ED in outpatients with advanced LC. ⋯ Conclusions: ED is highly prevalent and severe in outpatients with advanced LC experiencing BD. The association between intrathoracic comorbidities and oxygen therapy points to alveolar oxygen exchange failure having a potential etiopathogenic role in ED in this population. Further studies are needed to better characterize ED in LC to better inform treatments and trial protocols.
