JAMA :数字乳腺断层合成X线成像技术对间隔浸润性和晚期乳腺癌发病风险的影响

2022-06-19 zhangfan MedSci原创

与常规乳腺X光检查相比,DBT筛查不能降低间隔浸润性乳腺癌风险,对于占总人数3.6%的致密型乳腺且乳腺癌高风险女性,DBT可降低晚期乳腺癌风险,但其他人群中DBT无明显优势


数字乳腺断层合成X线成像技术(DBT)可显著提高致密型乳腺女性人群乳腺癌检出率,2021年美国81%的女性乳腺癌筛查使用了DBT。近日研究人员比较DBT vs 常规乳腺X光检查对间隔浸润性和晚期乳腺癌发病风险的影响。

BCSC研究中,504427 名40-79岁的女性,在2011-2018年间,在44个美国研究中心接受了1003900 次乳腺X光筛查和375189 次DBT检查,记录受筛查人群的乳腺密度,乳腺癌诊断随访至2019年。研究的主要终点是筛查后12个月内间隔浸润性癌和晚期乳腺癌。

参与者接受筛查时平均年龄为58岁。DBT组与乳腺X光检查组相比,每1000次检查的间隔浸润性癌风险没有显著差异(0.57 vs 0.61),筛查后中低风险人群的5年乳腺癌风险低于1.67%,但致密型乳腺人群的5年乳腺癌风险高于1.67%。在中低风险人群,几乎完全脂肪、多量纤维腺体型乳腺或乳腺密度不均的高危人群中,DBT与X光检查相比,组间晚期乳腺癌发病率没有显著差异。对于乳腺密度极高且乳腺癌风险较高的女性(占总人数的3.6%),DBT与X光检查相比,每1000次检查中,DBT组晚期乳腺癌发生率明显较低(DBT组检查13291 次,X光检查组检查31300 次;每1000次检出率0.27 vs 0.80;差异−0.53),但对于其他人群,DBT的优势不显著(DBT组10611 次,X光检查组37796次;每1000次检出率0.54 vs 0.42次;差异0.12)。

组间乳腺癌、间隔浸润性乳腺癌以及晚期乳腺癌风险差异

研究认为,与常规乳腺X光检查相比,DBT筛查不能降低间隔浸润性乳腺癌风险,对于占总人数3.6%的致密型乳腺且乳腺癌高风险女性,DBT可降低晚期乳腺癌风险,但其他人群中DBT无明显优势
