ARID1A and neoplasm: To understand the survival difference in different subgroups stratified by CD47 expression and ARID1A status, we further investigated the tumor-infiltrating immune cell infiltration difference in different subgroups stratified by low/high CD47 expression and mutated/wild-type ARID1A expression by using quanTIseq and EPIC algorithms in the analysis of the data from TCGA.
