median survival time

(MEE-dee-un ser-VY-vul …)

The length of time from either the diagnosis or the treatment of a disease, such as cancer, to the point at which half of the patients diagnosed with the disease are still alive. In a clinical trial, measuring the median survival time is one way to see how well a new treatment works. Also called median overall survival and median survival.
