“…For predicting chest wall invasion in cases where the tumor is adjacent to the chest wall without bone destruction or without a mass involving the chest wall, CT has a limited accuracy (sensitivity, 38–90%; specificity, 40–96%). [ 7 , 14 ] Signs of chest wall invasion (PL3) observed in CT images include blunt angle, pleural contact >3 cm, and adjacent pleural thickening. [ 7 – 10 ] Previous reports show that the conventional criteria used to predict chest wall invasion had accuracy of 68% to 83.3%; sensitivity of 67% to 87%; specificity of 43.9% to 91.3%; PPV of 20.7% to 53.8%; and NPV of 81.8% to 96%.…”

The aim of the study is to evaluate the use of the tumor border in peripheral non-small cell lung cancer (NSCLC) as an indicator of pleural invasion.This retrospective study was performed at a single tertiary center. The analysis of 136 patients with peripheral NSCLC included 101 (74.3%) patients with pathologically proven pleural invasion and 35 (25.7%) patients without pleural invasion. The tumor borders on conventional computed tomography (CT) were classified into 5 types on lung window setting: type 1, S or reverse S border with a blunt angle; type 2, sharp angle; type 3, concave border with a blunt angle; type 4, straight border with a perpendicular angle; and type 5, convex border with a perpendicular or blunt angle. In patients with more than 1 tumor border type, the priority was type 5, 4, 3, 2, and 1. Blunt angle, pleural contact >3 cm, and adjacent pleural thickening were also recorded for comparison with pleural invasion of peripheral tumors.Tumor border types 2 and 5 significantly differed between patients with and without pleural invasion (P = .001 and P < .001, respectively). Patients with and without pleural invasion did not significantly differ in tumor border type 1, tumor border type 3, tumor border type 4, blunt angle, pleural contact >3 cm, or pleural thickening. Tumor border type 5 was a moderate indicator of pleural invasion with positive LR, 5.20; accuracy, 57%; sensitivity, 45%; specificity, 91%; PPV, 94%; and NPV, 36%. Tumor border type 2 was a weak indicator of pleural invasion with positive LR, 0.51; accuracy, 34%; sensitivity, 34%; specificity, 34%; PPV, 60%; and NPV, 15%.Tumor border type 5 has a high PPV and high specificity for predicting pleural invasion by peripheral NSCLC.

For patients with NSCLC resected by VATS lobectomy, cumulative institutional experience significantly and positively affects the adequacy of lymphadenectomy. This may be related to the initial surgeon's learning curve with VATS lobectomy. As the experience with VATS lobectomy becomes more mature, the procedure is increasingly being performed on older patients, often with more compromised pulmonary function and more advanced stage disease. Despite the expanded inclusion of older and sicker patients for VATS lobectomy, no compromise was seen in their disease-free survival.
