Abstract:
Objective To explore the expression of PIN1 and Cyclin E in gastric carcinoma tissue after radical gastrectomy and its significance.Methods 46 patients received radical gastrectomy were selected as study subjects.Cancer tissues were harvested as the gastric cancer group,and the adjacent normal tissues of tumor tissue were harvested as the control group.The expression of PIN1 and Cyclin E was observed by immunohistochemistry,and the relationship with tumor infiltration,differentiation,lymphatic and distant metastasis were analyzed.A five year followup study was also applied.Results The expression of PIN1 (3 949.66 ± 157.40) and Cyclin E (5 443.07 ±240.15) was significantly higher than those of the control group[(247.67 ± 75.63),(354.92 ± 93.88)] (all P ＜0.05),and the expression of PIN1 was related with tumor differentiation,lymphatic and distant metastasis,and the expression of Cyclin E was closely related with tumor infiltration and differentiation.The 5-year survival rate of patients with the simultaneously increased expression of PIN1 and Cyclin E was 50.0％,which was significantly lower than the expression of the two separate elevated or not elevated.Conclusion The expression of PIN1 and Cyclin E in cancer tissues after radical gastrectomy is high,and could better reflect the pathological parameters and prognosis.
