Correlation analysis of six prognostic MDGs (ABCG1, KDF1, KITLG, TGFA, HAVCR2, and CD14) and six types of immune infiltrating cells, including tumor purity, B cells, CD8+T cells, CD4+T cells, macrophages, neutrophils, and dendritic cells (Figures 8A–F) was performed. The gene discussed is KITLG; the disease is neoplasm.
