Summary

This study looks at how immune cells called T cells change in people with advanced melanoma, lung, or other cancers during anti-PD-1 therapy. Researchers will measure specific markers in blood samples to see if they can predict treatment response or resistance. The goal is to understand why some patients benefit from this immunotherapy while others do not. About 500 adults who are starting or continuing anti-PD-1 treatment will participate.
