TGFB1 and gastric cancer: To identify GPSGC-associated specific molecular targets, 60 detectable immunomodulatory genes were analyzed in the entire cohort of 834 GC patients and were significantly correlated with the GPSGC risk score (Pearson's correlation test, |r| ≥ 0.40, P < 0.05); the genes are listed in Figure 5C. OS analysis further showed that only three immunomodulatory genes, VEGFB, TGFβ1 and ENTPD1, were significantly associated with poor outcomes.
