1 Oncological Characteristics of Radiological Invasive Adenocarcinoma with Additional Ground-Glass Nodules on Initial Thin-Section Computed Tomography: Comparison with Solitary Invasive Adenocarcinoma  Aritoshi Hattori, MD, Takeshi Matsunaga, MD, Kazuya Takamochi, MD, Shiaki Oh, MD, Kenji Suzuki, MD  Journal of Thoracic Oncology  Volume 11, Issue 5, Pages (May 2016) DOI: /j.jtho Copyright © 2016 International Association for the Study of Lung Cancer Terms and Conditions

2 Figure 1 A radiologically invasive tumor was defined as a lung tumor with a consolidation tumor ratio (CTR) of at least 0.5 but no greater than 1.0. A part solid tumor was defined as a lung tumor with a ground-glass opacity component (i.e., 0.5 ≤ CTR < 1.0) (left), whereas pure solid tumor was defined as a tumor showing consolidation only and without ground-glass opacity on thin-section computed tomography (i.e., CTR = 1.0) (right).

3 Figure 2 Additional ground-glass nodules (GGNs) were tentatively defined as any lung nodule with a pure GGN or GGN-predominant appearance showing a smaller diameter than that of the main tumor that was detected in the initial survey for radiological invasive adenocarcinoma on thin-section computed tomography scan (yellow circle).

4 Figure 3 Overall survival is shown for patients with clinical stage T1N0M0 radiological invasive adenocarcinoma with or without additional ground-glass nodules (AGGNs). The 5-year overall survival rate for patients with AGGNs was 92.2% (red line), and for those without AGGNs, it was 79.9% (black line), showing a significant difference between the two study arms (p = ).
