Risk-reducing endocrine therapy use, though the benefit is validated, is extremely low. The FDA has approved tamoxifen and raloxifene for a 5-year Breast Cancer Risk Assessment Tool (BCRAT) risk ≥ 1.67%. We examined the threshold at which high-risk women are likely to be using endocrine risk-reducing therapies among Athena Breast Health Network participants from 2011–2018. We identified high-risk women by a 5-year BCRAT risk ≥ 1.67% and those in the top 10% and 2.5% risk thresholds by age. We estimated the odds ratio (OR) of current medication use based on these thresholds using logistic regression. One thousand two hundred and one (1.2%) of 104,223 total participants used medication. Of the 33,082 participants with 5-year BCRAT risk ≥ 1.67%, 772 (2.3%) used medication. Of 2445 in the top 2.5% threshold, 209 (8.6%) used medication. Participants whose 5-year risk exceeded 1.67% were more likely to use medication than those whose risk was below this threshold, OR 3.94 (95% CI = 3.50–4.43). The top 2.5% was most strongly associated with medication usage, OR 9.50 (8.13–11.09) compared to the bottom 97.5%. Women exceeding a 5-year BCRAT ≥ 1.67% had modest medication use. We demonstrate that women in the top 2.5% have higher odds of medication use than those in the bottom 97.5% and compared to a risk of 1.67%. The top 2.5% threshold would more effectively target medication use and is being tested prospectively in a randomized control clinical trial.

升高的风险阈值可预测 Athena 筛查登记中内分泌风险降低药物的使用

使用降低风险的内分泌疗法虽然益处已得到证实,但极低。FDA 已批准他莫昔芬和雷洛昔芬用于 5 年乳腺癌风险评估工具 (BCRAT) 风险≥1.67%。我们检查了 2011 年至 2018 年雅典娜乳房健康网络参与者中高危女性可能使用内分泌风险降低疗法的阈值。我们通过 5 年 BCRAT 风险 ≥ 1.67% 和年龄在前 10% 和 2.5% 风险阈值中的女性来识别高风险女性。我们使用逻辑回归根据这些阈值估计了当前药物使用的优势比 (OR)。104,223 名参与者中有 1201 人(1.2%)使用过药物。在 5 年 BCRAT 风险 ≥ 1.67% 的 33,082 名参与者中,772 (2.3%) 名使用药物。在前 2.5% 阈值的 2445 人中,209 人(8.6%)使用过药物。5 年风险超过 1.67% 的参与者比风险低于该阈值(OR 3.94)的参与者更有可能使用药物(95% CI = 3.50–4.43)。前 2.5% 与药物使用的相关性最强,OR 9.50 (8.13–11.09) 与后 97.5% 相比。超过 5 年 BCRAT ≥ 1.67% 的女性有适度的药物使用。我们证明,前 2.5% 的女性使用药物的几率高于后 97.5% 的女性,而风险为 1.67%。最高的 2.5% 阈值将更有效地针对药物使用,并且正在随机对照临床试验中进行前瞻性测试。09) 与底部的 97.5% 相比。超过 5 年 BCRAT ≥ 1.67% 的女性有适度的药物使用。我们证明,前 2.5% 的女性使用药物的几率高于后 97.5% 的女性,而风险为 1.67%。最高的 2.5% 阈值将更有效地针对药物使用,并且正在随机对照临床试验中进行前瞻性测试。09) 与底部的 97.5% 相比。超过 5 年 BCRAT ≥ 1.67% 的女性有适度的药物使用。我们证明,前 2.5% 的女性使用药物的几率高于后 97.5% 的女性,而风险为 1.67%。最高的 2.5% 阈值将更有效地针对药物使用,并且正在随机对照临床试验中进行前瞻性测试。
