TFRC and metastatic malignant neoplasm in the lymph nodes: The univariate Cox’s model for 5-year survival of GC patients revealed that TfR1 expression was one of the prognostic factors (hazard ratio (HR) = 0.533; 95% confidence interval (CI): 0.348–0.817; P = 0.004), and the other prognostic factors included lymph node metastasis (P < 0.001), depth of invasion (P < 0.001), distant metastasis (P < 0.001), and tumor size (P < 0.001).
