Correlation of Expression of Connexin 43 and Clinicopathological Characteristics and Prognosis of Gastric Cancer

Objective To study the expression of connexin 43(Cx43)and its correlation with clinicopathological features and prognosis of gastric cancer patients.Methods The expression of Cx43 in 68 cases of gastric cancer and normal tissues adjacent to cancer(>5 cm away from tumor margin)was determined by immunohistochemistry,and the correlation between Cx43 expression and clinicopathological features was analyzed.Kaplan-Meier was used to construct the total survival curve and disease-free survival curve,and Cox regression analysis was used to evaluate the independent influencing factors on the prognosis of gastric cancer patients.Results The positive expression rate of Cx43 in gastric cancer tissues(51.47%)was lower than that of the normal tissues adjacent to cancer(95.58%)(P<0.001).The expression of Cx43 was significantly correlated with the maximum diameter of tumor(P=0.004)and the depth of tumor invasion(P=0.012).In addition,Cox regression analysis showed that the expression level of Cx43,tumor maximum diameter,tumor differentiation degree and the depth of tumor invasion were independent influencing factors on prognosis of gastric cancer patients.Conclusion The expression of Cx43 is related to the clinicopathological features and prognosis of gastric cancer patients,Cx43 may be used as a potential prognostic indicator of gastric cancer patients.
