Expression of survivin, cyclinD1, p21(WAF1), caspase-3 in cervical cancer and its relation with prognosis.

The implications of Survivin, CyclinD1, p21(WAF1), Caspase-3 in the development, progression and prognosis in cervical cancer were investigated. By using immunohistochemical SP method, the expression of Survivin, CyclinD1, p21(WAF1), Caspase-3 was detected in 41 cases of cervical cancer, 17 cases of cervical intraepithelial neoplasia (CIN) and 10 cases of normal tissues, and their relation with pathological grade, clinical stage, metastasis and survival time was analyzed. The results showed that the positive expression rate of Survivin, CyclinDl in cervical cancer was significantly higher than in CIN group and normal control group (P < 0.05). The median survival time in the patients with cervical cancer positive for Survivin and CyclinD1 was significantly shorter than in those with negative expression (P < 0.05). The expression of both Survivin and CyclinD1 was not related with tumor grade, clinical stage and metastasis (P > 0.05). The positive expression rate of p21(WAF1) , Caspase-3 in cervical cancer was significantly lower than in CIN group and normal control group (P < 0.05), and had a close relation with tumor grade (P <0.05). The expression of Survivin in cervical cancer in cervical cancer was negatively associated with that of Caspase-3 (P < 0.01), but positively with that of CyclinD1 (P < 0.01). Cox Multivariate analysis revealed that Survivin was the independent prognostic indicator influencing the survival time of the patients with cervical cancer (P < 0.05). It was suggested that the high expression of Survivin or CyclinD1, and low expression of p21(WAF1) or Caspase-3 was closely correlated with the development of cervical cancer. Survivin and CyclinD1 could be used as a useful indicator to predict the prognosis of cervical cancer.
