The heterogeneity in the immune cell response to CRC highlights the need to develop novel immune diagnostics that could predict the risk of disease relapse and devise a secondary strategy to address that risk. The purpose of this study was to prospectively provide a clear description of the patient-specific immune landscape present in CRC to target the dominant immune suppressive factors within a given tumor that may improve response rates while ushering in the age of personalized therapies for cancer patients. We described a functional interplay between neutrophils and CD8+ T cells that impacts on tumor immune escape and relapse.
