Abstract:
Objective:To investigate the use of Fisher discriminant function model that is established on the basis of CT morphological features,for lesion before infiltration and invasive lesions of the ground-glass nodules(GGN) sample early lung adenocarcinoma.Methods:A retrospective study was conducted in 160 cases of GGN sample early lung adenocarcinoma.These cases in Jingzhou central hospital and Dongfeng general hospital from September 2014 to February 2017 were confirmed by pathology.The CT morphological features were evaluated by chi-square test and Fisher discriminant was applied to parameter with significant difference.Cross-validation was used for estimating the rate of miscarriage justice.Results:160 patients with GGN were divided into two groups,the lesion before infiltration group (n=53),invasive lesions group (n=107).Spicule signs,lobulation sign,nodules form, nodule interface,average diameter,pleural indentation sign,vascular convergence sign and presence of solid components were significant difference.The formula of fisher discriminant was Z=2.046X1+2.006X2+2.015X3-1.473X4+0.189X5+0.023X6+1.813X7+1.957X8-1.687.The rate of miscarriage of justice was 6.3%,the accuracy was 93.7%.Conclusion:Fisher discriminant mode for differential diagnosis GGN sample early lung adenocarcinoma before infiltration and invasive lesions had high accuracy and the clinical practical value.
