在这项研究中,我们试图将雄激素受体(AR)的表达与乳腺癌患者的肿瘤进展和无病生存期(DFS)相关联。我们对450名乳腺癌患者的AR表达进行了研究。我们发现,与雌激素受体(ER)阴性的癌症相比,表达雌激素受体的乳腺癌更有可能共同表达AR(56.0%对28.1%,P < 0.001)。此外,我们发现AR表达与管腔型乳腺癌患者的无病生存期增加相关(P < 0.001),而与三阴性乳腺癌(TNBC)患者的无病生存期降低相关(P = 0.014)。此外,在所有受体组合中,激素受体阳性(HR +)且AR低水平表达的肿瘤患者无病生存期最短。我们还提出了一种使用AR受体状态和BRCA1的新型预后模型,并提供数据表明,与传统的TMN分期系统相比,我们的模型对无病生存期更具预测性。
In this study we sought to correlate androgen receptor (AR) expression with tumor progression and disease-free survival (DFS) in breast cancer patients. We investigated AR expression in 450 breast cancer patients. We found that breast cancers expressing the estrogen receptor (ER) are more likely to co-express AR compared to ER-negative cancers (56.0% versus 28.1%, P < 0.001). In addition, we found that AR expression is correlated with increased DFS in patients with luminal breast cancer (P < 0.001), and decreased DFS in TNBC (triple negative breast cancer, P = 0.014). In addition, patients with HR+ tumors (Hormone receptor positive tumors) expressing low levels of AR have the lowest DFS among all receptor combinations. We also propose a novel prognostic model using AR receptor status, BRCA1, and present data showing that our model is more predictive of disease free survival compared to the traditional TMN staging system.
