Abstract

Background: Limited data exist regarding the utility and validity of the 21-gene recurrence score (RS) in patients with de novo metastatic breast cancer (dnMBC). This study aimed to investigate the practice patterns as well as associated survival outcomes based on 21-gene RS in dnMBC.

Research design and methods: The Surveillance, Epidemiology, and End Results Oncotype database was queried for women with hormone receptor-positive and Her2-negative dnMBC.

Results: A total of 153 patients were identified, including 62.7% and 37.3% of patients who had RS < 26 and ≥ 26, respectively. Patients with RS ≥ 26 were more likely to receive chemotherapy compared to those with RS < 26 (61.4% vs. 28.1%, p < 0.001). Patients with RS ≥ 26 had an inferior breast cancer-specific survival (BCSS) (2-year BCSS: 84.3% vs. 89.5, p = 0.067) and overall survival (OS) compared to those with RS < 26 (2-year OS: 76.9% vs. 87.4%, p = 0.018). The multivariate Cox proportional hazard models showed that those with RS ≥ 26 had a significantly inferior BCSS (hazard ratio [HR] 2.251, 95% confidence interval [CI] 1.056-4.799, p = 0.036) and OS (HR 2.151, 95%CI 1.123-4.120, p = 0.021) compared to those with RS < 26.

Conclusions: The 21-gene RS assay is an important prognostic factor in patients with dnMBC.

新发转移性乳腺癌中 21 基因复发评分的使用和结果。

背景：关于21基因复发评分（RS）在新发转移性乳腺癌（dnMBC）患者中的实用性和有效性的数据有限。本研究旨在调查基于 21 基因 RS 的 dnMBC 患者的实践模式及相关生存结果：研究设计：对激素受体阳性和 Her2 阴性 dnMBC 女性患者的监测、流行病学和最终结果 Oncotype 数据库进行了查询：共确定了153名患者，其中62.7%和37.3%的患者有RS（P = 0.067），总生存期（OS）与有RS的患者相比P = 0.018）。多变量考克斯比例危险模型显示，与RS结论者相比，RS≥26者的BCSS（危险比[HR]2.251，95%置信区间[CI]1.056-4.799，P = 0.036）和OS（HR 2.151，95%CI 1.123-4.120，P = 0.021）明显较差：21基因RS检测是dnMBC患者的重要预后因素。
