On univariate Cox regression analysis ER+/AR+ tumours showed significantly better OS than ER+/AR- tumours (p = 0.047) and ER-negative, AR-negative (ER−/AR-) tumours showed significantly better DFS than ER-negative, AR-positive (ER−/AR+) tumours (p = 0.036) (Fig. 4). This evidence concerns the gene AR and neoplasm.
