Kaplan Meier survival analysis of progression-free survival (PFS). a PFS in all ovarian cancer cases in relation to PR expression. PFS of patients without expression of PR was compared to survival of patients with PR expression (p = 0.0261). The chi-square statistic of the log-rank was used to investigate differences between survival curves. P-values below 0.05 were considered statistically significant. PFS of those patients whose tumors express PR (IRS ≥ 1) compared to those with PR negative tumors (IRS 0); b PFS of ovarian cancer patients whose tumors expressing Ki-67 compared to those with low or absent Ki-67 expression (p = 0.0134)
