Overall survival
The percentage of patients still alive after a set period — a key clinical trial endpoint.
What it is
Overall survival is a measure of how long patients with cancer live after starting treatment. It's usually expressed as a percentage of people who are still alive after a certain period, like one year or five years. This measure helps doctors and researchers understand how well a treatment is working.
How it works
In a clinical trial, researchers track how long patients live after starting a new treatment. They compare this to how long patients lived when they received a standard treatment. By looking at overall survival, researchers can see if the new treatment is better, worse, or about the same as the standard treatment.
Why it matters
Understanding overall survival is important because it helps doctors and researchers make informed decisions about which treatments to use. It also gives patients and their families a better idea of what to expect from a treatment. By looking at overall survival, researchers can identify which treatments are most effective and make them available to more people.
