Background Although Breast Imaging Reporting and Data System (BI-RADS) density classification has been used to assess future breast cancer risk, its reliability and validity are still debated in literature. Purpose To determine the association between overall longitudinal changes in mammographic breast density and breast cancer risk stratified by menopausal status. Materials and Methods In a retrospective cohort study using the Korean National Health Insurance Service database, women aged at least 40 years without a history of cancer who underwent three consecutive biennial mammographic screenings in 2009-2014 were followed up through December 2020. Participants were divided according to baseline breast density: fatty (BI-RADS categories a, b) versus dense (BI-RADS categories c, d) and then into subgroups on the basis of changes from the first to second and from second to third screenings. Women without change in breast density were used as the reference group. Main outcomes were incident breast cancer events, both invasive breast cancer and ductal carcinoma in situ. Cox proportion hazard regression was used to calculate the hazard ratio (HR) with adjustment for other covariables. Results Among 2 253 963 women (mean age, 59 years ± 9) there were 22 439 detected breast cancers. Premenopausal women with fatty breasts at the first screening had a higher risk of breast cancer as density increased in the second and third screenings (fatty-to-dense HR, 1.45 [95% CI: 1.27, 1.65]; dense-to-fatty HR, 1.53 [95% CI: 1.34, 1.74]; dense-to-dense HR, 1.93 [95% CI: 1.75, 2.13]). In premenopausal women with dense breasts at baseline, those in whom density continuously decreased had a 0.62-fold lower risk (95% CI: 0.56, 0.69). Similar results were observed in postmenopausal women, remaining significant after adjustment for baseline breast density or changes in body mass index (fatty-to-dense HR, 1.50 [95% CI: 1.39, 1.62]; dense-to-fatty HR, 1.42 [95% CI: 1.31, 1.53]; dense-to-dense HR, 1.62 [95% CI: 1.51, 1.75]). Conclusion In both premenopausal and postmenopausal women undergoing three consecutive biennial mammographic screenings, a consecutive increase in breast density augmented the future breast cancer risk whereas a continuous decrease was associated with a lower risk. © RSNA, 2022 Online supplemental material is available for this article.

纵向乳房 X 线摄影乳房密度变化与随后的乳腺癌风险的关联。

背景 尽管乳腺影像报告和数据系统 (BI-RADS) 密度分类已被用于评估未来的乳腺癌风险,但其可靠性和有效性在文献中仍存在争议。目的 确定乳腺 X 光密度的总体纵向变化与按绝经状态分层的乳腺癌风险之间的关联。材料和方法 在一项使用韩国国民健康保险服务数据库的回顾性队列研究中,年龄在 40 岁以上且没有癌症病史且在 2009-2014 年连续三年接受乳房 X 光检查的女性在 2020 年 12 月之前进行了随访。基线乳房密度:脂肪(BI-RADS 类别 a、b)与致密(BI-RADS 类别 c、d) 然后根据从第一次放映到第二次放映和从第二次放映到第三次放映的变化分成小组。乳房密度没有变化的女性被用作参考组。主要结局是乳腺癌事件,包括浸润性乳腺癌和导管原位癌。Cox比例风险回归用于计算风险比(HR)并调整其他协变量。结果 在 2 253 963 名女性(平均年龄,59 岁 ± 9)中,检测出 22 439 例乳腺癌。第一次筛查时乳房脂肪的绝经前妇女患乳腺癌的风险更高,因为在第二次和第三次筛查中密度增加(脂肪-致密 HR,1.45 [95% CI:1.27,1.65];致密-脂肪 HR , 1.53 [95% CI: 1.34, 1.74];密对密 HR, 1.93 [95% CI: 1.75, 2.13])。在基线时乳房致密的绝经前妇女中,那些密度持续下降的人的风险降低了 0.62 倍(95% CI:0.56,0.69)。在绝经后妇女中观察到类似的结果,在调整基线乳房密度或体重指数变化后仍然显着(脂肪-致密 HR,1.50 [95% CI:1.39,1.62];致密-脂肪 HR,1.42 [ 95% CI:1.31,1.53];密对密 HR,1.62 [95% CI:1.51,1.75])。结论 在绝经前和绝经后的妇女中,连续三年进行两年一次的乳房 X 光检查,乳腺密度的连续增加增加了未来患乳腺癌的风险,而持续降低与较低的风险相关。© RSNA, 2022 本文提供在线补充材料。另见本期 Kataoka 等人的社论。56, 0.69). 在绝经后妇女中观察到类似的结果,在调整基线乳房密度或体重指数变化后仍然显着(脂肪-致密 HR,1.50 [95% CI:1.39,1.62];致密-脂肪 HR,1.42 [ 95% CI:1.31,1.53];密对密 HR,1.62 [95% CI:1.51,1.75])。结论 在绝经前和绝经后的妇女中,连续三年进行两年一次的乳房 X 光检查,乳腺密度的连续增加增加了未来患乳腺癌的风险,而持续降低与较低的风险相关。© RSNA, 2022 本文提供在线补充材料。另见本期 Kataoka 等人的社论。56, 0.69). 在绝经后妇女中观察到类似的结果,在调整基线乳房密度或体重指数变化后仍然显着(脂肪-致密 HR,1.50 [95% CI:1.39,1.62];致密-脂肪 HR,1.42 [ 95% CI:1.31,1.53];密对密 HR,1.62 [95% CI:1.51,1.75])。结论 在绝经前和绝经后的妇女中,连续三年进行两年一次的乳房 X 光检查,乳腺密度的连续增加增加了未来患乳腺癌的风险,而持续降低与较低的风险相关。© RSNA, 2022 本文提供在线补充材料。另见本期 Kataoka 等人的社论。在调整基线乳房密度或体重指数变化后仍然显着(脂肪-致密 HR,1.50 [95% CI:1.39,1.62];致密-脂肪 HR,1.42 [95% CI:1.31,1.53] ;密对密 HR,1.62 [95% CI:1.51,1.75])。结论 在绝经前和绝经后的妇女中,连续三年进行两年一次的乳房 X 光检查,乳腺密度的连续增加增加了未来患乳腺癌的风险,而持续降低与较低的风险相关。© RSNA, 2022 本文提供在线补充材料。另见本期 Kataoka 等人的社论。在调整基线乳房密度或体重指数变化后仍然显着(脂肪-致密 HR,1.50 [95% CI:1.39,1.62];致密-脂肪 HR,1.42 [95% CI:1.31,1.53] ;密对密 HR,1.62 [95% CI:1.51,1.75])。结论 在绝经前和绝经后的妇女中,连续三年进行两年一次的乳房 X 光检查,乳腺密度的连续增加增加了未来患乳腺癌的风险,而持续降低与较低的风险相关。© RSNA, 2022 本文提供在线补充材料。另见本期 Kataoka 等人的社论。结论 在绝经前和绝经后的妇女中,连续三年进行两年一次的乳房 X 光检查,乳腺密度的连续增加增加了未来患乳腺癌的风险,而持续降低与较低的风险相关。© RSNA, 2022 本文提供在线补充材料。另见本期 Kataoka 等人的社论。结论 在绝经前和绝经后的妇女中,连续三年进行两年一次的乳房 X 光检查,乳腺密度的连续增加增加了未来患乳腺癌的风险,而持续降低与较低的风险相关。© RSNA, 2022 本文提供在线补充材料。另见本期 Kataoka 等人的社论。
