The goal of this clinical research study is to learn if dexamethasone can help reduce
shortness of breath in cancer patients. Researchers also want to learn if it can help to
improve lung function and quality of life. In this study, dexamethasone will be compared to a
placebo.
Dexamethasone is commonly used for treatment of nausea, tiredness, and pain. It may help
patients with shortness of breath.
A placebo is not a drug. It looks like the study drug but is not designed to treat any
disease or illness. It is designed to be compared with a study drug to learn if the study
drug has any real effect.
