Jiang et al. analysed the utility of intratumoural and peritumoural radiomic features to predict tumour and/or invasive margin levels of CD8+, CD3+, CD45RO+, and CD66b+ immune cells in gastric cancer (validation AUC = 0.766, 95% CI: 0.669–0.863) [44]. The gene discussed is CD8A; the disease is neoplasm.
