First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks for proteins and other markers in the blood of 2000 adults with or suspected of having cancer. The goal is to find markers that may help doctors confirm a cancer diagnosis, choose the right treatment, and predict how well a patient will respond or if the cancer will return. Participants must be 18 or older, have a prior cancer diagnosis or suspicion of cancer, and be in good enough health to undergo standard treatment.
