Purpose: The purpose of the study is to retrospectively evaluate the safety and efficacy of microwave ablation (MWA) for the treatment of ground-glass opacity (GGO)-lung adenocarcinoma.Materials and Methods: From December 2013 to June 2017, a total of 51 patients (22 males and 29 females, mean age of 69.4 ± 10.1 years) were included in this study, with 51 lung adenocarcinoma lesions showing GGO (mean long-axis diameter of 18.7 ± 6.05 mm). They received a total of 52 sessions of percutaneous computed tomography-guided (CT-guided) MWA. First, lung adenocarcinoma with GGO was histologically defined by needle biopsy under the guidance of CT. Second, the efficacy of CT-guided MWA was analyzed, including the feasibility, safety, 3 years local progression-free survival (LPFS), 3 years disease-specific survival, and 3 years overall survival (OS). Final, complications after MWA were also summarized.Results: The technical success rate was 100%, without MWA procedure-related death. At the median follow-up period (27.02, range: 7-45 months), the rates of 3 years LPFS, cancer-specific survival, and OS were 98%, 100%, and 96%, respectively. The complications after MWA included pneumothorax (48.1%, 25/52), hemoptysis (28.8%, 14/52), pleural effusion (23.1%, 12/52), and pulmonary infection (7.7%, 4/52).Conclusions: CT-guided percutaneous MWA was a feasible, safe, and effective therapeutic approach for treating GGO-lung adenocarcinoma.
