客观的。我们研究的目的是证明筛查性乳房X光照片的批量读取可以在不牺牲癌症检测的情况下降低召回率。材料和方法。我们分析了 2001 年 10 月至 2003 年 7 月连续筛查性乳房 X 光检查的召回率、癌症检出率、最小癌症检出率、低期癌症检出率和肿瘤大小。最初的 7,984 张乳房 X 线照片是在繁忙的乳腺成像实践中进行解读的。尽管这些研究不是在网上阅读的，但解释经常因电话、手术和诊断性乳房X光检查而中断。其余 1,538 项研究在建立专门的不间断批量读取后进行了解释。结果。引入批量读取之前和之后的召回率分别为 20.1% 和 16.2% (p < 0.001)。癌症检出率没有显着差异：每 1,000 次检查中未检测到 5.6 例癌症，每 1,000 例进行批量读数时检测到 7.2 例癌症。这些组之间诊断出的乳腺癌的预后因素也没有显着差异。在批量读取前诊断出的筛查检测癌症中，微小癌症占 67%，低期癌症占 76%。在使用批量读取诊断的癌症中，73% 为微小癌症，91% 为低期癌症。癌症的平均大小，无批量读数时为 11.7 毫米，有批量读数时为 9.1 毫米，也没有显示出统计学上的显着差异。 结论。我们的经验表明，批量读取可以显着降低筛查乳房X光检查召回率，而不影响癌症检出率或具有良好预后指标的癌症诊断比例。
OBJECTIVE. The objective of our study was to prove that batch reading of screening mammograms can reduce recall rates without sacrificing cancer detection.MATERIALS AND METHODS. We analyzed recall rate, cancer detection, minimal cancer detection, detection of low-stage cancer, and tumor size from consecutive screening mammography examinations from October 2001 to July 2003. The initial 7,984 mammograms were interpreted in the midst of a busy breast imaging practice. Although these studies were not read online, the interpretations were often interrupted for telephone calls, procedures, and diagnostic mammograms. The remaining 1,538 studies were interpreted after the institution of dedicated uninterrupted batch reading.RESULTS. Recall rates were 20.1% before and 16.2% after the introduction of batch reading (p < 0.001). Cancer detection rates were not significantly different: 5.6 cancers were detected per 1,000 examinations without and 7.2 were detected per 1,000 with batch reading. Prognostic factors for breast cancers diagnosed between these groups also were not significantly different. Of the screening-detected cancers diagnosed before batch reading, minimal cancers comprised 67% and low-stage cancers accounted for 76%. Of the cancers diagnosed using batch reading, 73% were minimal and 91% were low stage. The mean size of cancers, 11.7 mm without batch reading and 9.1 mm with batch reading, also showed no statistically significant difference.CONCLUSION. Our experience shows that batch reading can significantly reduce screening mammography recall rates without affecting the cancer detection rate or the proportion of cancers diagnosed with favorable prognostic indicators.
