1 Prognostic Impact of the Findings on Thin-Section Computed Tomography in Patients with Subcentimeter Non–Small Cell Lung Cancer  Aritoshi Hattori, MD, Takeshi Matsunaga, MD, Takuo Hayashi, MD, Kazuya Takamochi, MD, Shiaki Oh, MD, Kenji Suzuki, MD  Journal of Thoracic Oncology  Volume 12, Issue 6, Pages (June 2017) DOI: /j.jtho Copyright © 2017 International Association for the Study of Lung Cancer Terms and Conditions

2 Figure 1 Typical findings of subcentimeter NSCLC are presented on the basis of the findings of thin-section computed tomography (CT) scan. Pure ground glass opacity (GGO) tumor was defined as a lung tumor without a solid component (i.e., CTR = 0) and part solid tumor was defined as a lung tumor with both a GGO and solid component (i.e., 0＜CTR＜1.0), whereas pure solid tumor was defined as a tumor showing only consolidation without GGO on thin-section CT (i.e., consolidation-to-tumor ratio [CTR] = 1.0).

3 Figure 2 The overall survival (OS) and recurrence-free survival (RFS) of 328 patients with c-N0 subcentimeter NSCLC are demonstrated. The 5-year OS and RFS rates were extremely better in patients with a pure ground glass opacity (GGO) (OS and RFS = 100%) or part solid (OS = 97.5%, RFS = 94.9%) tumor, whereas those of patients with pure solid subcentimeter NSCLC were 87.6% and 79.3% (OS: p = ; RFS: p < ), respectively.

4 Figure 3 Locoregional recurrence-free survival (RFS) according to the operative modes was demonstrated in patients with radiologically determined part solid or pure solid subcentimeter NSCLC. A marginal difference was observed between the two study arms, and the 5-year locoregional RFS was 92.3% for the anatomical resection arm but 86.2% for the wedge resection arm (p = ).
