Potential Molecular Markers Related to Lymph Node Metastasis and Stalk Resection Margins in Pedunculated T1 Colorectal Cancers Using Digital Spatial Profiling: A Pilot Study with a Small Case Series.

In the comparison of the fold change in gene expression levels of B2M , HLA - B , and HLA - E genes between the distal stalk invasion and proximal stalk invasion groups, we observed an increase in the proximal stalk region compared to the head region, but this difference did not reach statistical significance ( p = 0.544).
