After correction for age, tumor size, stage and grade, ER/PR/HER2 status and 3-gene classifier subtype, the loss of WRN (p=0.053; HR 1.2), DUSP26 (p=0.022; HR 1.3), UNC5D (p=0.026; HR 1.3), ZNF703 (p=0.026; HR 1.3) and FGFR1 (p=0.002; HR 1.5) still predicted worse DFS. This evidence concerns the gene DUSP26 and neoplasm.
