High AR expression was a significant favorable prognostic factor for overall survival in all of the subjects and subgroups with a tumor size of ≤2 cm, a negative node, a positive ER, a negative HER2, a histologic grade 1 or 2, a body mass index ≤25 kg/m2, a lumpectomy, and endocrine therapy (Figure 2). This evidence concerns the gene AR and neoplasm.
