CT腺癌经气道播散？

本研究旨在识别能够预测与手术切除肺腺癌经气道播散（STAS）的CT征象。

本研究旨在识别能够预测与手术切除肺腺癌经气道播散（STAS）的CT征象。

本研究共纳入了948例行肺腺癌手术切除的患者，并评价是否有STAS。利用患者指标将STAS阳性和STAS阴性匹配比例为1：2.利用多变量Logistic回归分析和ROC曲线评价CT征象（例如实性成分百分比、实性成分最大径、病变密度、位置、边界、形状、假空洞征、钙化、中心低密度征、外周淡磨玻璃密度征、空气支气管征、卫星灶和胸膜牵拉征）。

结果为，本研究共纳入了276例患者，其中129例男性和147例女心。STAS阳性和STAS阴性分别为92例、184例。STAS多常见于实性肿瘤，其次为亚实性肿瘤，最少见于磨玻璃密度灶。STAS也与中心低密度征、边界淡磨玻璃密度、空气支气管征和实性成分百分比具有相关性。实性成分百分比是预测STAS的独立预测指标，以90%为最佳截断值的鉴别敏感性、特异性分别为89.2%、60.3%。

本研究表明，肺腺癌实性成分百分比与经气道播散具有独立相关性。
