Hong et al. [24] showed that Tgd cells, mast cells, Th2 cells, and Th1 cells were related to the prognosis of STAD; Wang et al. [25] reported that immune cell infiltration (Th2 and mast cells) was closely related to the survival of STAD patients, and Ma et al. [26] reported that metastasis of STAD was altered by enhancing epithelial-mesenchymal changes. The gene discussed is ABCA1; the disease is gastric adenocarcinoma.
