Blood Test to Predict Recurrence Across Early-Stage Cancers

This research is being done to see if a new blood test can predict whether cancer will recur (come back) after initial treatment. Sometimes, cancer is cured after initial treatment, but in other cases, cancer cells remain in the body. These cells can grow over time. If not treated or caught in time, they may become incurable. Today, doctors are not usually able to accurately predict which cancers will come back and which ones are already cured which leads to uncertainty about the best way to treat the person's cancer. In addition, cancer recurrences are often caught too late using tests available today. The Sponsor of this research, Guardant Health, has developed a blood test to detect remaining cancer cells. We believe this test could help detect recurrent cancer earlier and more accurately than other tests available today. This research will determine just how accurate the Guardant Health test is.
