Abstract:
Objective:To investigate the association between the parameters of thin-section computed tomography and the invasion and histological subtypes of subsolid nodules measuring 1-2 centimeters in diameter as lung adenocarcinoma.Methods:We retrospectively reviewed the cases with subsolid nodules measuring 1-2 centimeters on thin-section computed tomography and histologically confirmed as lung adenocarcinoma.Results:A total of 135 patients were enrolled in this study, including 23 with pure ground glass nodules and 112 with part-solid ground glass nodule. We observed significant differences of nodule size, solid component size, consolidation-to-tumor ratio, nodule attenuation and attenuation ratio( P<0.0001). The receiver operating curve indicated certain predictive value of solid component size, nodule attenuation and attenuation ratio: AUC were 0.838(0.756-0.919)、0.823(0.729-0.917) and 0.820(0.726-0.914), respectively. Of the invasive adenocarcinoma, those with solid or micropapillary components merely showed a significance in solid component size( P=0.024). Conclusion:The parameters of thin-section computed tomography of 1-2 centimeters subsolid nodules showed significant differences in varied invasiveness of lung adenocarcinoma, and these could have certain predictive value.
