Abstract:
Objective To investigate the influence of preoperative arterial chemoembolization on the expression of Survivin,and study the clinical significance in bladder cancer.Methods The tissue before and after chemoembolization of 50 patients with bladder cancer were selected,the Survivin expression was examined by immunohistochemical method.The Survivin expression was compared between before and after chemoembolization in bladder cancer tissue,and the relation of its expression to the pathological grade and clinical stage was evaluated clinically.Results The positive rate of Survivin expression before chemoembolization raised with the rising of the pathological grade and clinical stage,there was statistical difference (P ＜ 0.05).The positive rate of Survivin expression before and after chemoembolization was 72％ (36/50) and 22％ (11/50),there was statistical difference (P ＜0.01).The positive rate of Survivin expression in high grade pathological grade and T2-T4 clinical stage after chemoembolization was significantly lower than that before chemoembolization,there was statistical difference (P ＜0.01).The survival rate 3 years after chemoembolization in Survivin negative expression patients was higher than that in Survivin positive expression patients [94.87％(37/39) vs.7/11],but there was no statistical difference (P ＞ 0.05).The Survivin positive expression in recurrence patients was significantly higher than that in non-recurrence patients [5/8 vs.5.56％ (2/36)],there was statistical difference (P ＜ 0.01).Conclusions Preoperative arterial chemoembolization can reduce the expression of Survivin,adjust malignancy of bladder cancer,could downgrade and downstage the tumor,reduce recurrence rate.The expression of Survivin can serve as predictive factor for prognosis of bladder cancer.
