CD8A and malignant colon neoplasm: The CIBERSORT-based analysis method clarified the infiltration level of 22 immune cells in colon cancer patients, and the results showed that lncRNAs used to construct the model had a strong correlation with the polarization of B cells, CD8+ T cells and M0 macrophages (Figure 8), indicating that these lncRNAs may regulate tumor growth and progression by affecting the tumor immune infiltration microenvironment.
