Abstract

The Androgen Receptor (AR) is a potential prognostic marker and therapeutic target in breast cancer. We evaluated AR protein expression in high-risk breast cancer treated in the adjuvant setting. Tumors were subtyped into luminal (ER+/PgR±/AR±), molecular apocrine (MAC, [ER-/PgR-/AR+]) and hormone receptor negative carcinomas (HR-negative, [ER-/PgR-/AR-]). Subtyping was evaluated with respect to prognosis and to taxane therapy. High histologic grade (p < 0.001) and increased proliferation (p = 0.001) more often appeared in MAC and HR-negative than in luminal tumors. Patients with MAC had outcome comparable to the luminal group, while patients with HR-negative disease had increased risk for relapse and death. MAC outcome was favorable upon taxane-containing treatment; this remained significant upon multivariate analysis for overall survival (HR 0.31, 95%CI 0.13-0.74, interaction p = 0.035) and as a trend for time to relapse (p = 0.15). In conclusion, AR-related subtyping of breast cancer may be prognostic and serve for selecting optimal treatment combinations.

摘要

雄激素受体(AR)是乳腺癌潜在的预后标志物和治疗靶点。我们评估了辅助治疗的高危乳腺癌中AR蛋白的表达情况。肿瘤被分为腔面型(ER+/PgR±/AR±)、分子大汗腺型(MAC,[ER-/PgR-/AR+])和激素受体阴性癌(HR阴性,[ER-/PgR-/AR-])。对各亚型的预后和紫杉烷治疗情况进行了评估。与腔面型肿瘤相比,高组织学分级(p < 0.001)和增殖增加(p = 0.001)在MAC和HR阴性肿瘤中更常见。MAC患者的预后与腔面型组相当,而HR阴性疾病患者的复发和死亡风险增加。含紫杉烷治疗对MAC患者的预后有利;在多因素分析总体生存情况时,这一结果仍具有显著性(HR 0.31,95%CI 0.13 - 0.74,交互作用p = 0.035),且在复发时间方面呈趋势性显著(p = 0.15)。总之,基于AR的乳腺癌亚型分类可能具有预后价值,并有助于选择最佳治疗方案。
