The expression of EphB2 in left-side and right-side colon cancer tissues and its correlation with prognosis

Objective:To investigate the expression of EphB2 protein in human colon cancer tissues,we compared the expression of EphB2 protein between left colon cancer(LCC)and right colon cancer(RCC)tissues and analyzed its prognostic value.Methods:180 cases of colon cancer specimens were selected for radical resection in Kunshan Hospital Affiliated to Jiangsu University.Immunohistochemistry was used to detect the expression of EphB2 protein in colon cancer tissues and para-carcinoma tissues,and the pathological parameters and prognosis were analyzed.Results:In the LCC tissues,EphB2 was negatively correlated with histological grade,lymph node metastasis and Dukes stage.EphB2 protein expression was not related to age,gender,histological type,tumor size,histological grade,lymph node metastasis and Dukes stage in RCC tissues.The 5-year survival rate of LCC was significantly higher than that of RCC.Although EphB2 expression was not related to 5-year overall survival(OS)in all patients or patients with RCC.Low level of EphB2 in the LCC patients predicted poor prognosis.Conclusion:In the LCC and RCC tissues,EphB2 was negatively correlated with histological grade,lymph node metastasis and Dukes stage.Low level of EphB2 in the LCC patients predicted poor prognosis.
