CDH17 and neoplasm: The review of the literature shows a focus on CDH17 from other perspectives, analyzing the diagnostic value and prognostic significance of serum CDH17 (together with serum miR-378e) [25], the importance of single-nucleotide polymorphisms in the CDH17 gene [26,27], and the effectiveness of identifying CDH17 in circulating tumor cells compared to tissue immunoexpression for the non-invasive detection of CRC [28].
