RBM3 and gastric cancer: Ultimately, the depth of the primary tumor invasion was identified as an independent postoperative predicator with the OS of gastric cancer patients, as were the PLNs(HR = 1.715; 95%CI 1.176–2.500; P = 0.005), the NLNs (HR = 0.689; 95%CI 0.481–0.987; P = 0.042), and the RNPL (HR = 0.653; 95%CI 0.470–0.970; P = 0.011) (Figures 1, 2, and 3 and Table 3).
