CD8A and neoplasm: We estimated the fractions of ten immune cell types to total cells in ACGEJ and adjacent normal samples using our bulk RNA sequencing data and found CD8 + T and NK cells present (>0%) in 97.6% (120/123) and 98.4% (121/123) tumor samples, respectively, but the most prevalent immune cell types in tumors were immune suppressive regulatory T cells (Treg, median 5.49%).
