谁知道无病生存率和无事件生存率的差别

Event-free survival is calculated when a particular treatment is given that is directed not towards improving survival, but to prevent or delay specific complications of the disease.

Disease-free survival (DFS) denotes the chances of staying free of disease after a particular treatment for a group of individuals suffering from a cancer. It is the percentage of individuals in the group who are likely to be free of disease after a specified duration of time. Disease-free survival rates are an indication of how effective a particular treatment is.
