Definition of Disease-free survival

Disease-free survival: The length of time after treatment during which no disease is found. Can be reported for an individual patient or for a study population.

"Disease-free survival predicts survival. It always has. And there is a very big decrease in cancer incidence so there will be a survival difference." (Dr. Larry Norton, in The New York Times, Oct 10, 2003)
