Based on the above analysis results of RBM8A expression in cancer and survival prognosis, we finally selected 7 types of cancer to analyze the relationship between RBM8A and immune infiltration cells in TIMER, which were ESCA, LIHC, and KIRP to represent cancers with worse survival and BLCA, CESC, KIRC, and LUAD to represent cancers with good survival when RBM8A had a high level of expression. This evidence concerns the gene RBM8A and cancer.
