Core Tip

Core tip: The expression of proliferating cell nuclear antigen (PCNA) and E-cadherin was detected by immunohistochemistry in gastric tissues of 186 patients. During the transition of normal gastric mucosa to gastric cancer, the PCNA labeling index gradually increased, while the E-cadherin labeling index gradually decreased (P < 0.05). There was a negative correlation between the expression of PCNA and E-cadherin in gastric carcinoma. High T stage and positive PCNA expression were risk factors for the prognosis of patients with gastric cancer (RR > 1), while the positive expression of E-cadherin was a protective factor (RR < 1). Combined detection of PCNA and E-cadherin can improve the accuracy of assessing the prognosis of patients with gastric cancer.
