In summary, the novel TME-related signature consisting of CADM3, LEP, CD1B, PDE1B, CCL22, ABI3BP, IGLON5, SELE, and TGFB1 is an effective, practical, and quantitative approach for clinicians to predict survival and to provide individualized treatment for colon cancer patients and is expected to be further utilized in future clinical practice. This evidence concerns the gene PDE1B and colonic neoplasm.
