CAGE1 and cancer: We speculated that a large number of immune cell infiltration and immune-related pathways were enriched in CT1, which was considered to be an immune-inflammatory type; a large number of innate immune cell infiltration and cancer-promoting activation-related pathways were enriched in CT2, and CT2 was considered an immune excluded type; there was a lack of immune cell infiltration in CT3, which was considered an immune desert type.
