ABSTRACT
This study was to detect the expression level of transferrin receptor 2 (TfR2) in gastric cancer and to analyze its value in predicting the prognosis of gastric cancer patients. Real-time PCR (RT-qPCR) was applied to detect the mRNA expression of TfR2 in gastric cancer tissues and paired adjacent nontumorous tissues. Immunohistochemistry (IHC) and western blotting were used to determine the protein expression of TfR2 in gastric cancer, and the relationship with the prognosis of gastric cancer patients was analyzed. The results were (1) The mRNA and protein levels of TfR2 in gastric cancer tissues were remarkably lower than those in adjacent nontumorous gastric tissue (P < .05). (2) Clinicopathological analysis showed that the expression level of TfR2 was significantly correlated with TNM stage of patients (P = .047). (3) The results of univariate survival analysis showed that histological grade, T stage, N stage, M stage, Lauren's classification, and TfR2 expression level influenced the overall survival of gastric cancer patients. Multivariate survival analysis showed that low TfR2 expression (HR = 1.671, 95%CI 1.006-2.774, P = .047), poor differentiation (HR = 2.123, 95%CI 1.188-3.795, P = .011), and M1 stage (HR = 8.541, 95%CI 3.416-21.353, P < .001) were independent risk factors affecting the overall survival of gastric cancer patients. In conclusion, TfR2 exhibited low expression in gastric cancer tissue, and is an independent prognostic factor of gastric cancer patients.
