Response rate
The proportion of patients whose cancer shrinks or disappears after treatment.
What it is
Response rate is a measure of how well a cancer treatment works. It's calculated by looking at the number of patients whose cancer shrinks or disappears after treatment, compared to the total number of patients who received the treatment. In some cases, a response rate can be a good indicator of whether a treatment is effective.
How it works
Doctors and researchers use imaging tests, such as CT scans or MRIs, to measure the size of a patient's tumor before and after treatment. They then compare these measurements to determine if the tumor has shrunk or disappeared. This information is used to calculate the response rate, which can help doctors and researchers understand how well a treatment is working.
Why it matters
Understanding response rates can help doctors and researchers decide which treatments to use for future patients. It can also help researchers develop new treatments that are more effective. By tracking response rates over time, researchers can get a better sense of how well different treatments work for different types of cancer.
