JAMA:乳房钼靶摄像二次读片顺序对乳腺癌检出率有影响吗?

2016-05-12 MedSci MedSci原创

对乳房钼靶筛查的解读是一项困难且重复的工作,可能会导致癌症漏诊和假阳性结果而被召回。在美国进行了一项每2两位读片专家独立评估每张摄像寻找癌症的迹象并按照批次顺序检验摄像结果的研究。然而,警戒递减现象(即随着作业时间的推移而检测率下降)在相似的情况下出现了。

对乳房钼靶筛查的解读是一项困难且重复的工作,可能会导致癌症漏诊和假阳性结果而被召回。在美国进行了一项每2两位读片专家独立评估每张摄像寻找癌症的迹象并按照批次顺序检验摄像结果的研究。然而,警戒递减现象(即随着作业时间的推移而检测率下降)在相似的情况下出现了。

为了检测改变乳房钼靶摄像二次读片批次顺序对乳腺癌检出率的影响。研究人员进行了一项多中心,双盲、随机对照试验。该研究在来自英国的国家医疗服务(NHS)乳腺筛查计划46个乳腺筛查中心开展,历时1年(全部在2012年12月20日到2014年11月3日)。360位读片者参加了研究(平均每个中心7.8人)——186位放射科医生,143位摄像先进工作者和31个乳腺科医生,所有人都符合NHS乳腺筛查计划中做出乳房钼靶筛查报告的完整资格。对照组中,每两位读片者以相同的顺序对每批数码乳房钼靶筛查进行了检验,而在干预组中则以相反的顺序进行读片检验。

主要终点是乳腺癌的检出率,次要终点是召回率和读片人员之间的分歧。

在1194147例乳房钼靶筛查女性中(平均年龄59.3,SD,7.49)(干预组596642例,对照组597507例),37688批(中位批次大小:35)图像进行了解读,每位读片者所解读的中位批次为176(IQR, 96-278)。在所有后续诊断检测完成之后,共发现乳腺癌10484例(0.88%)。在癌症检测率上无明显差异,干预组发现5272例癌症(0.88%),对照组发现5212例癌症(0.87%)(差异,0.01%;95%CI −0.02% to 0.04%), 召回率,24 681 [4.14%] vs 24 894 [4.17%]; 差异−0.03% 95% CI, −0.10% to 0.04%,读片者分歧率,3.43%比3.48%。

结论:

对于有经验的读片人员,对乳房钼靶摄像在二次读片时,使用相同顺序或不同顺序对乳腺癌检出率无显著差异。
