Abstract excerpt
While mismatch repair-deficient (dMMR) colorectal cancers (CRCs) exhibit strong immunogenicity and better response to immune checkpoint inhibitors, the more prevalent mismatch repair-proficient (pMMR) CRCs typically show poor T- cell infiltration and inferior outcomes. Profiling the limited tumor-infiltrating CD8+ T cells helps identify responders and guides new strategies to enhance their infiltration and...
