Six of the nine survival-related genes (CORO1A, CD180, SASH3, CD52, CD300A, and CD14) were involved in the immune pathways, and were all were negatively correlated with survival, which is consistent with our understanding of the duality of immunity in tumors: immune has dual roles of suppressing and promoting cancer (Schreiber et al., 2011). Here, CD52 is linked to cancer.
