CD8A and neoplasm: We have generated a four-lncRNA prognostic risk score model consisting of COMETT, EMX2OS, AC026462.3, and HAGLR. The risk score was positively significantly correlated with the infiltration abundances of six immune cell types, including B cells, CD4 T cells, CD8 T cells, dendritic cells, macrophages, and neutrophils, suggesting the close and strong relationship with hypoxia microenvironment and tumor immune activity.
