    Abstract:
    BACKGROUND: The aim of this study was to evaluate association of expression of survivin and p53 with the effects of neoadjuvant chemotherapy (NAC) in patients with advanced ovarian cancer (AOC). METHODS: We retrospectively evaluated 60 consecutive patients with AOC (International Federation of Gynecology and Obstetrics stage IIIC-IV) treated with NAC. The expression of p53 and survivin was assessed immunohistochemically. The median of expression total score survivin equals 2 was adopted to dichotomize the group. The positive and negative expression of p53 was used to dichotomize the group. RESULTS: The expression of survivin in tumor tissue taken before and after NAC was a significant difference in the percentage of stained nuclei (P = 0.0002), the intensity of staining (P = 0.0003), and total score (P = 0.0001). There was a significant difference in p53 expression in tumor tissue before and after NAC in the percentage of stained nuclei (P = 0.0424). Survivin expression, in contrast to p53 expression, was a prognostic factor in patients with AOC treated with NAC (P = 0.0484). The expression of survivin and p53 was not a predictive factor. Independent adverse predictor factors were as follows: lack of optimal interval debulking surgery and the lack of an objective response (the respective hazard ratio was 3.93 [95% confidence interval, 2.07-7.46; P < 0.0001] and 2.36 [95% confidence interval,1.25-4.47; P = 0.0080]). The suboptimal range of interval debulking surgery, resistance to platinum, and the lack of paclitaxel in the NAC were adverse prognostic factors (the respective hazard ratio was 2.61 [95% confidence interval, 1.17-5.83], 2.72 [95% confidence interval, 1.07-6.89], and 2.56 [95% confidence interval, 1.06-6.18]; P < 0.05]). CONCLUSIONS: High expression of survivin could be a prognostic factor in patients treated with NAC for AOC.
