摘　　要：目的探讨计算机辅助测量亚实性肺结节实性成分质量比(CTRmass)对预测术前临床IA期肺腺癌浸润性的价值。方法回顾性选取临汾市中心医院及美国肺部筛查试验(NLST)数据库(项目编号NLST-1053)IA期肺腺癌患者56例,均经病理证实,利用计算机辅助软件自动计算肿瘤实性成分体积比(CTRvol)、CTRmass、平均CT值、轴位最大径等参数,并分析其与病理结果的相关性。结果当CTRmass≥30.95%时,则表明肺结节更倾向为浸润性腺癌(IAC)。结论利用计算机辅助软件测量的CTRmass可作为判断临床IA期肺腺癌术前评估浸润性的重要指标之一,进而指导手术方式的选择,获取更理想的疗效。Objective To explore the value of computer-aided measurement of the mass-based consolidation-to-tumor ratio(CTRmass)in predicting preoperative clinical stage IA lung adenocarcinoma invasion.Methods A total of 56 patients with stage IA lung adenocarcinoma were retrospectively selected from Linfen Central Hospital and the National Lung Screening Trial(NLST)database(project number NLST-1053),and all of them were confirmed by pathology.Computer-aided software was used to automatically calculate parameters such as the volume-based consolidation-to-tumor ratio(CTRvol),CTRmass,average CT value,and maximum axial diameter,and its correlation with pathological results was analyzed.Results When the CTRmass≥30.95%,it indicated that lung nodules were more likely to be invasive adenocarcinoma(IAC).Conclusion CTRmass,based on computer-aided software measurement,can be used as one of the important indicators to evaluate the preoperative invasion of clinical stage IA lung adenocarcinoma,guiding the selection of surgical methods,and obtaining better curative effects.
