Factors influencing survival in the univariate analysis were: LB HER2+ AR+ subtype (p: 0.010); age at diagnosis (p < 0.0001); histological type (p: 0.006); histological grade (p: 0.003); tumor size (p < 0.0001); lymph node status and ratio (p < 0.0001 for both); prognostic stage (p < 0.0001); metastasis (p < 0.0001); Ki-67 expression (p: 0.002); ER, PR, and AR expression (p: 0.008, p: 0.010, and p: 0.008, respectively) (Table 5). This evidence concerns the gene ESR1 and neoplasm.
