ABSTRACT
The aim of the present study was to evaluate ephrin type-A receptor 5 (EphA5) expression and its clinicopathological significance in gastric cancer. Gastric cancer tissues were analyzed by immunohistochemistry. The association between EphA5 expression and clinicopathological parameters, human epidermal growth factor receptor 2 (HER2) status and Ki-67 proliferation index was statistically analyzed. EphA5 expression was detected in all non-tumor gastric epithelia but was differentially expressed among gastric cancer samples. EphA5 was negatively expressed in 30/110 (27.3%) and positively expressed in 80/110 (72.3%) samples from patients with gastric cancer. EphA5 expression was significantly associated with Lauren classification (P=0.032), lymph node metastasis (P<0.001), HER2 expression (P=0.020) and Ki-67 expression (P=0.005). No significant association was determined between EphA5 expression and age, sex, primary location, depth of invasion and Tumor-Node-Metastasis stage. The present data indicated that EphA5 is differentially expressed in gastric cancer. EphA5 may therefore be a potential therapeutic target and may have clinical utility as a marker for lymph node metastasis in gastric cancer.
