overall survival (oh-ver-AWL ser-VY-vul)

The length of time a person lives after being diagnosed with a life-threatening disease, such
as cancer, until death from any cause. In a randomized clinical trial, overall survival may be
measured from the time a person is assigned to treatment instead of the time of diagnosis.
Measuring differences in overall survival between groups of patients receiving different
treatments in a clinical trial is one way to see if one treatment works better than another. Also
called OS and overall survival time.
