This single-arm multi-institutional prospective study aimed to evaluate the 10-year outcomes of sublobar resection for small-sized ground-glass opacity-dominant lung cancer. Among 73 patients prospectively enrolled from 13 institutions between November 2006 and April 2012, 53 ground-glass opacity-dominant lung cancer patients underwent sublobar resection with wedge resection as the first choice. The inclusion criteria were maximum tumor size of 8–20 mm; ≥ 80% ground-glass opacity ratio on high-resolution computed tomography; lower 18F-fluorodeoxyglucose accumulation than the mediastinum; intraoperative pathological diagnosis of adenocarcinoma in situ; and no cancer cells on intraoperative cut margins. The primary endpoint was a 10-year disease-specific survival. The 53 eligible patients had a mean tumor size of 14 ± 3.4 mm and a mean ground-glass opacity ratio of 95.9 ± 7.2%. Wedge resection and segmentectomy were performed in 39 and 14 patients, respectively. The final pathological diagnoses were adenocarcinoma in situ in 47 patients (88.7%) and adenocarcinoma with mixed subtype in 6 patients (11.3%). The 10-year disease-specific survival and overall survival were 100% and 96.2%, respectively, during a median follow-up period of 120 months (range, 37–162 months). Ground-glass opacity-dominant small lung cancer is cured by sublobar resection when patients are strictly selected by the inclusion criteria of this study. [ABSTRACT FROM AUTHOR]
