Abstract Background: Eosinophils are innate immune granulocytes that migrate to areas of inflammation to combat against infection and disease. Best known for their detrimental role in asthma and allergic disorders, there is growing interest in the involvement of eosinophils in cancer. Eosinophils are routinely observed in the tumor microenvironment (TME) and, depending on the cancer type, have been shown to drive other immune cells to either suppress or promote tumor growth - In colorectal cancer (CRC), eosinophil infiltration into the TME has been linked to a favorable prognosis. However, the behavior of eosinophils and their effect on associated immune mediators in the TME remains poorly understood. Currently, eosinophils are primarily identified from H Part 1 (Regular Abstracts) ; 2024 Apr 5-10; San Diego, CA. Philadelphia (PA): AACR; Cancer Res 2024;84 (6Suppl): Abstract nr 2352.
