Abstract:
Purpose To study the expression of eIF-4E and p-4EBP-1 and its clinical significance in the gastric carcinoma.Methods Expression of eIF-4E and p-4EBP-1 was detected in tissue array including 168 cases of gastric carcinoma and 52 cases of peri-cancer tissues by immunohistochemical SP method.Results The positive expression of eIF-4E and p-4EBP-1 in the gastric carcinoma was significantly higher than that of peri-cancer tissues (P =0.001,P =0.000).There was significantly higher expression of eIF-4E and p-4EBP-1 with lymph node metastases than without lymph node metastases in the gastric carcinoma (P =0.025,P =0.001).Also,there was significantly higher expression of eIF-4E and p-4EBP-1 with clinical stages Ⅲ + Ⅳ than that of stages Ⅰ + Ⅱ (P =0.001,P=0.049).In addition,there was a significantly positive correlation between the expression of eIF-4E and p-4EBP-1 in the gastric carcinoma (r =0.432,P < 0.01).The overall survival rates for patients with negative expression of eIF-4E protein was higher than that with positive expression (P =0.012).Conclusion The abnormal co-expression of eIF-4E and p-4EBP-1 may be related to the tumorgenesis,development,metastasis and invasion of gastric carcinoma,and eIF-4E and p-4EBP-1 may act as the new molecular targets for the therapy and diagnosis of gastric carcinoma.
