Given the high heterogeneity among breast tumors, associations between common germline genetic variants and survival that may exist within specific subgroups could go undetected in an unstratified set of breast cancer patients. We performed genome-wide association analyses within 15 subgroups of breast cancer patients based on prognostic factors, including hormone receptors, tumor grade, age, and type of systemic treatment. Analyses were based on 91,686 female patients of European ancestry from the Breast Cancer Association Consortium, including 7531 breast cancer-specific deaths over a median follow-up of 8.1 years. Cox regression was used to assess associations of common germline variants with 15-year and 5-year breast cancer-specific survival. We assessed the probability of these associations being true positives via the Bayesian false discovery probability (BFDP < 0.15). Evidence of associations with breast cancer-specific survival was observed in three patient subgroups, with variant rs5934618 in patients with grade 3 tumors (15-year-hazard ratio (HR) [95% confidence interval (CI)] 1.32 [1.20, 1.45], P = 1.4E−08, BFDP = 0.01, per G allele); variant rs4679741 in patients with ER-positive tumors treated with endocrine therapy (15-year-HR [95% CI] 1.18 [1.11, 1.26], P = 1.6E−07, BFDP = 0.09, per G allele); variants rs1106333 (15-year-HR [95% CI] 1.68 [1.39,2.03], P = 5.6E−08, BFDP = 0.12, per A allele) and rs78754389 (5-year-HR [95% CI] 1.79 [1.46,2.20], P = 1.7E−08, BFDP = 0.07, per A allele), in patients with ER-negative tumors treated with chemotherapy. We found evidence of four loci associated with breast cancer-specific survival within three patient subgroups. There was limited evidence for the existence of associations in other patient subgroups. However, the power for many subgroups is limited due to the low number of events. Even so, our results suggest that the impact of common germline genetic variants on breast cancer-specific survival might be limited.

在由与肿瘤生物学和全身治疗类型相关的临床病理变量定义的患者亚组中,种系遗传变异与乳腺癌特异性生存的关联

鉴于乳腺肿瘤之间的高度异质性,在未分层的乳腺癌患者组中,可能无法检测到特定亚组中可能存在的常见种系遗传变异与生存之间的关联。我们根据激素受体、肿瘤分级、年龄和全身治疗类型等预后因素,对 15 个乳腺癌患者亚组进行了全基因组关联分析。分析基于乳腺癌协会联盟的 91,686 名欧洲血统女性患者,其中包括 7531 名乳腺癌特异性死亡患者,中位随访时间为 8.1 年。Cox 回归用于评估常见种系变异与 15 年和 5 年乳腺癌特异性生存率的关联。我们通过贝叶斯错误发现概率 (BFDP < 0.15) 评估了这些关联为真阳性的概率。在三个患者亚组中观察到与乳腺癌特异性生存相关的证据,其中 3 级肿瘤患者中存在 rs5934618 变异(15 年风险比 (HR) [95% 置信区间 (CI)] 1.32 [1.20, 1.45] ,P = 1.4E−08,BFDP = 0.01,每个 G 等位基因);接受内分泌治疗的 ER 阳性肿瘤患者中的变异 rs4679741(15 年 HR [95% CI] 1.18 [1.11, 1.26],P = 1.6E−07,BFDP = 0.09,每个 G 等位基因);变体 rs1106333(15 年 HR [95% CI] 1.68 [1.39,2.03],P = 5.6E−08,BFDP = 0.12,每个 A 等位基因)和 rs78754389(5 年 HR [95% CI] 1.79 [ 1.46,2.20],P = 1.7E−08,BFDP = 0.07,每个 A 等位基因),在接受化疗的 ER 阴性肿瘤患者中。我们在三个患者亚组中发现了四个与乳腺癌特异性生存相关的基因座的证据。其他患者亚组中存在关联的证据有限。然而,由于事件数量较少,许多小组的权力受到限制。即便如此,我们的结果表明,常见种系遗传变异对乳腺癌特异性生存的影响可能有限。
