Abstract

To retrospectively investigate the clinical characteristics, surgical treatments of the patients with lung ground-glass opacities (GGO). Methods All the patients, who underwent surgical resection of GGO in our department from Jan. 2013 to Dec. 2016 were retrospectively reviewed. The clinicpathological features were analyzed. Results A total of 663 patients were included in this study. The rate of malignancy was 92.6% (614/663). The diameter of GGO in benign group 〔(0.8±0.2) cm〕 was significant smaller than that in malignant group 〔（1.5±0.8） cm〕(P<0.001). The rate of irregular margin in malignant group was far higher than that in benign group (93.8% vs. 20.4%，P<0.001), but other CT signs such as vacuole sign, plural retraction, speculation and lobulation did not show significant difference between the two groups. A total of 652 (98.3%) cases were resected by video-assisted thoracoscopic surgery (VATS), and only 11 (1.7%) cases were resected by thoracotomy. A total of 336 (50.7%) patients underwent lobectomy, 226 (34.1%) underwent segmentectomy and 101 (15.2%) undewent wedge resection. The rate of surgery-related complications was 9.0% (60/663), and one (0.2%) patient died. Conclusion With careful selection of GGO by experienced surgeons, the rate of malignancy is very high. Surgical resection may be recommended for highly suspected malignant cases. Sublobar resection or lobcotomy by VATS can achieve good treatment effect.
