This research paper examines the role of mature tertiary lymphoid structures (mTLSs) as a superior tool for predicting how cancer patients will respond to immune checkpoint inhibitors. While current indicators like PD-L1 expression are often unreliable, this large-scale study of over 500 patients found that the presence of these immune cell clusters consistently correlates with higher survival rates and better treatment outcomes. These findings held true across various solid tumor types, including lung cancer and sarcoma, regardless of a patient's existing protein levels or T cell density. By…
