Tracking Tumor DNA During Radiation Therapy

We're doing this study to understand how a type of genetic material called DNA in the blood changes in people with a specific type of cancer that has spread to only a few places in the body. By looking at how this DNA behaves before and after cancer treatment, including radiation, we aim to learn more about how the cancer responds. To do this, we'll collect blood and tumor samples from you to analyze what's happening. This could help in better understanding and improving cancer treatments for others in the future.
