In univariate analysis (Table 3), high ERCG4 expression (HR = 0.84 [0.76-0.92]; p = 0.0002), as well as age superior to 50 years, node-negative status, small tumor size (pT1), low grade (SBR 1), positive ER and PR status, and negative ERBB2 status, were associated with a better DFS. This evidence concerns the gene ESR1 and neoplasm.
