Key Points
Question
What are the benefits and harms associated with pharmacologic interventions for managing breathlessness in adults with advanced cancer?
Findings
This systematic review and meta-analysis of 19 studies (17 randomized clinical trials and 2 retrospective studies) found that opioids and anxiolytics were not associated with improved breathlessness in patients with advanced cancer within the limits of the identified studies, which mainly focused on exertional breathlessness for opioids. Data on harms were too limited to draw conclusions.
Meaning
Although the existing data on opioids and pharmacologic interventions do not show an association with improved breathlessness in advanced cancer, they may be considered in selected patients in the context of potential harms and the evidence of an association of nonpharmacologic interventions with improved breathlessness.
