To further assess the risk predictive nature of the WID-OC-index we analysed 329 cervical samples from women with primary breast cancers with poor prognosis features (defined as >2 cm cancers and/or lymph-node positive and/or hormone-receptor negative and/or grade 3) and the 297 control samples from the ovarian cancer internal validation set. Here, NR4A1 is linked to ovarian carcinoma.
