本研究旨在比较Vancouver风险评价系统与ACR Lung-RADS预测肺恶性风险的价值。

本研究旨在比较Vancouver风险评价系统与ACR Lung-RADS预测肺恶性风险的价值。

本研究共纳入了2813例患者所包含的4408个肺结节资料进行评价。利用VRC联合9项指标(输出结果为恶性可能性,VRC阈值为恶性率超高5%)、Lung-RADS(输出结果为分类2-4B,恶性定义为4A或4B,恶性率超过5%)。利用Lung-RADS和VRC进行比较对每一位患者和每一处结节恶性评价的敏感性、特异性和准确性。

结果为,在4408处结节中,100/4078(2.5%)实性结节为恶性,10/330(3%)亚实性结节为恶性。对每一处结节进行分析中,VRC的敏感性、特异性和准确性分别为93%、90%、、90%,Lung-RADS的敏感性、特异性和准确性分别为87%、83%、83%(P = .077, P < .001, 和P < .001)。对每一例患者分析中,VRC的敏感性、特异性和准确性分别为93%、85%、85%,Lung-RADS的敏感性、特异性和准确性分别为87%、76%、76%(P = .077, P < .001和P < .001)。

本研究表明,Vancouver风险评价系统要比ACR Lung-RADS在预测肺结节恶性率具有较高的准确性。
