What is disease-free interval?
Abstract. The disease-free interval (DFI) is the period of time between the primary treatment of a malignancy and the first sign of tumor recurrence. The recording of this interval is necessarily approximate, because detection of a recurrence depends on how symptomatic it is or on how diligently it is looked for.
What is disease-free survival rate?
Disease-free survival (DFS) is a number that tells the chances of staying free of a disease or cancer after a particular treatment. It is the percentage of individuals in the treatment group who are likely to be free of the signs and symptoms of a disease after a specified duration of time.

What is the definition of disease free survival?

Which is a selection factor for the disease free interval?
Disease-free Interval In many series, an important prognostic and therefore selection factor is the disease-free interval (DFI), defined as the interval from the completion of chemotherapy to the diagnosis of recurrence.
Is the DFI and the platinum free interval the same?
The platinum-free interval is the interval of time between the last dose of platinum-based chemotherapy and the diagnosis of recurrence. Generally, the DFI and the platinum-free interval are the same, since almost all patients receive primary platinum-based chemotherapy.
