AR and neoplasm: There is currently no standardised assay to assess AR expression but recent data suggested that AR-targeted therapies may enhance the efficacy of chemotherapy even in TNBC with low AR expression by targeting cancer stem cell-like cells.10 In a meta-analysis of TNBC based on retrospective studies and population data, AR positivity was significantly associated with prolonged RFS but had no significant impact on OS.4 In our study, patients with AR + tumours had a poorer prognosis but AR was not an independent prognostic factor in multivariate analysis.
