PURPOSE
Data on utilization rate and cancer yield of BI-RADS® category 3 in routine clinical practice in diagnostic mammography are sparse. The aim of this study was to determine utilization rate and cancer yield of BI-RADS 3 in diagnostic mammography in the ACR National Mammography Database (NMD).
METHODS
Retrospective analysis of NMD mammograms from January 1, 2009, to June 30, 2018, was performed. BI-RADS 3 utilization rate in diagnostic setting was calculated and stratified by patient, facility, and examination-level variables. Patient-level cancer yield was calculated among women with BI-RADS 3 assessment and adequate follow-up (imaging follow-up ≥24 months or biopsy). Logistic regression was performed to assess the odds of utilization of BI-RADS 3, with respect to facility, examination, and patient variables, and the odds of malignancy among patients with probably benign findings. Chi-square and t tests were used to determine significance (P < .05).
RESULTS
Data from 19,443,866 mammograms from 500 NMD facilities across 31 states were analyzed, of which 3,039,952 were diagnostic mammograms. Utilization rate of BI-RADS 3 was 15.5% (470,155 of 3,039,952) in the diagnostic setting. There was a statistically significant difference in BI-RADS 3 utilization rate across all collected variables (P < .001). Patient-level cancer yield at 2-year follow-up was 0.91% (2,009 of 220,672; 95% confidence interval [CI], 0.87%-0.95%) in the diagnostic setting. Patient and examination variables associated with significantly higher likelihood of malignancy included calcifications (odds ratio, 4.27; 95% CI, 2.43-7.51), patient age > 70 years (odds ratio, 3.77; 95% CI, 2.49-5.7), and presence of prior comparisons (odds ratio, 1.23; 95% CI, 1.07-1.42).
CONCLUSIONS
In the NMD, BI-RADS 3 assessment was common in diagnostic mammography (15.5%), with an overall cancer yield of 0.91%, less than the benchmark of 2%. Utilization trends in diagnostic mammography warrant further research for optimization of use.
目的
常规临床诊断性乳腺 X 线摄影中 BI-RADS®第 3 类的利用率和癌症检出率数据较为匮乏。本研究旨在确定 ACR 国家乳腺 X 线摄影数据库（NMD）中诊断性乳腺 X 线摄影中 BI-RADS 第 3 类的利用率和癌症检出率。
方法
对 2009 年 1 月 1 日至 2018 年 6 月 30 日的 NMD 乳腺 X 线摄影进行回顾性分析。计算诊断性设置中 BI-RADS 第 3 类的利用率，并按患者、医疗机构和检查水平变量进行分层。在接受 BI-RADS 第 3 类评估且随访充分（影像学随访≥24 个月或活检）的女性中计算患者水平的癌症检出率。采用 logistic 回归分析评估与医疗机构、检查和患者变量相关的 BI-RADS 第 3 类利用情况的比值比，以及可能良性发现患者的恶性肿瘤比值比。采用卡方检验和 t 检验确定统计学意义（P＜0.05）。
结果
分析了来自 31 个州的 500 家 NMD 医疗机构的 19443866 份乳腺 X 线摄影，其中 3039952 份为诊断性乳腺 X 线摄影。在诊断性设置中，BI-RADS 第 3 类的利用率为 15.5%（470155/3039952）。在所有收集的变量中，BI-RADS 第 3 类的利用率存在统计学显著差异（P＜0.001）。在诊断性设置中，2 年随访时的患者水平癌症检出率为 0.91%（2009/220672；95%置信区间[CI]，0.87%-0.95%）。与恶性肿瘤发生风险显著增加相关的患者和检查变量包括钙化（比值比，4.27；95%CI，2.43-7.51）、患者年龄＞70 岁（比值比，3.77；95%CI，2.49-5.7）和存在既往比较（比值比，1.23；95%CI，1.07-1.42）。
结论
在 NMD 中，BI-RADS 第 3 类评估在诊断性乳腺 X 线摄影中较为常见（15.5%），总体癌症检出率为 0.91%，低于 2%的基准值。诊断性乳腺 X 线摄影的利用趋势值得进一步研究，以优化其应用。
