Abstract

Patient stratification is crucial for improving immunotherapy effectiveness. Acha-Sagredo et al. identified an interferon (IFN)-high immunophenotype and CD74 overexpression as predictors for immunotherapy response in colorectal cancer (CRC). This signature, involving cytotoxic T cells and antigen-presenting macrophages, was found in both mismatch repair-deficient and -proficient CRCs. CD74 overexpression could serve as a biomarker, enabling personalized CRC treatment.
