Emphysema | National Treatment Trial | Evaluation Program | Treatment Options | Patient Success Story | Education Resources
In 1997, the University of Maryland was awarded a National Institutes of Health (NIH) grant to become one of the 17 centers of excellence in the National Emphysema Treatment Trial (NETT).
This national clinical trial was designed to determine what is the best treatment for people with severe emphysema: medical management alone, which typically involves medication and rehabilitation or medical management plus lung volume reduction surgery (LVRS), in which damaged portions of each lung are removed.
The results of the NETT Study -- which were published in the May 22, 2003 edition of the New England Journal of Medicine -- indicate that, on average, patients who undergo LVRS with medical therapy are more likely to function better after two years and do not face an increased risk of death compared to those who receive medical therapy only.
