Medicine:Response rate

From HandWiki

In medicine, a response rate is the percentage of patients whose cancer shrinks or disappears after treatment. [1]

When used as a clinical endpoint for clinical trials of cancer treatments, this often called the objective response rate (ORR).[2][3]

The FDA definition of ORR is "the proportion of patients with tumor size reduction of a predefined amount and for a minimum time period."[2]:7
