To explore the effect of KIF20A on the immune response, we examined immunogenicity, immune checkpoints, immunophenoscore (IPS) (27), and tumor immune dysfunction and exclusion (TIDE) (28) scores, Aneuploidy score, cancer testis antigens (CTA) score, homologous recombination deficiency (HRD), and intratumor heterogeneity, all stratified by KIF20A expression. This evidence concerns the gene KIF20A and cancer.
