ESR2 and neoplasm: Besides the clinicopathological factors FIGO stage and residual tumor load after cytoreductive surgery, this coexpression pattern (ERbeta+/PELP1+) turned out to be the most relevant prognostic factor in univariate and multivariate survival analysis, revealing a significantly longer DFS (HR 0.3 [0.1-0.7], p = 0.004) and OS (HR 0.3[0.1-0.7], p = 0.005).
