Complete response criteria

Complete response (CR) criteria refer to specific standards used by medical professionals to determine if a patient’s disease, such as cancer, has fully disappeared after treatment. It means that on scans, tests, or examinations, no signs or evidence of disease are detectable. Achieving a complete response indicates that the treatment was effective enough to eliminate detectable illness, though ongoing monitoring is often necessary to ensure it does not return. These criteria help doctors assess progress, plan further care, and compare treatment outcomes.
