Summary

This study is observing 50 adults with advanced cancers (lung, breast, colorectal, gastric, or liver) who are starting immunotherapy. Researchers want to see if changes in ctDNA (bits of tumor DNA in the blood) can predict early whether the treatment is working. They will also check if standard markers like PD-L1 and TMB help predict response. The goal is to find better ways to monitor treatment without relying only on scans.
