RESUMEN
Objective To explore the expression of eukaryocyte initiation factors-4E (eIF-4E) in normal esophageal epithelium and different esophageal lesions tissue and its relationship with vascular endothelial growth factor (VEGF).Methods Thirty normal esophageal incisal margin tissues,32 atypical hyperplasia tissues,20 carcinoma in situ tissues and 117 esophageal invasive carcinoma tissues were selected from the biopsy specimens of the Department of Pathology,the First Affiliated Hospital of Xinxiang Medical University from March 2014 to March 2016.The expression of eIF-4E and VEGF were detected by immunohistochemistry method and the correlation between them was analyzed.Results The positive expression rate of eIF-4E in normal esophageal epithelium,atypical hyperplasia,carcinoma in situ and invasive carcinoma tissues was 0.0％ (0/ 30),9.4％ (3/32),45.0％ (9/20) and 80.3％ (94/117) respectively.There was no statistic difference in the positive expression rate of eIF-4E in normal esophageal epithelium and atypical hyperplasia tissues (P ＞ 0.05);there was statistic difference in the positive expression rate of eIF-4E in the other esophageal tissues(P ＜ 0.05).In 117 invasive carcinoma tissues,the positive expression rate of eIF-4E in metastatic carcinoma tissues (93.2％,55/59) was significantly higher than that in the non metastatic carcinoma tissues (67.2％,39/58) (P ＜ 0.05).The positive expression rate of eIF-4E in esophageal carcinoma tissues which invaded into shallow muscle layer,deep muscular layer and adventitia was 70.0％ (28/40),73.8％ (31/42) and 100.0％ (35/ 35) respectively;there was no statistic difference in positive expression rate of eIF-4E in the carcinoma tissues which invaded into shallow muscle layer and deep muscular layer(P ＞ 0.05);the positive expression rate of eIF-4E in the carcinoma tissues which invaded into shallow muscle layer and deep muscular layer was significantly lower than that in the carcinoma tissues which invaded into adventitia(P ＜0.01).The expression of eIF-4E in the esophageal invasive carcinoma tissues was positive VEGF(x2 =51.460,P ＜ O.05).Conclusion eIF-4E play an important role in the canceration of normal esophageal and the invasion,metastasis of esophageal carcinoma.The expression of eIF-4E is correlate with VEGF in esophageal carcinoma tissues.
