Comparative long-term prognosis of early surgery and surgery after surveillance for patients with ground-glass nodule adenocarcinomas.

To compare the pathological results and long-term survival results of early surgery and surgery after at least one year follow-up for ground-glass component predominant lung adenocarcinoma patients. From January 1, 2013 to August 31, 2017, a total of 279 patients with ground-glass nodules (GGNs) undergoing surgical resection and pathologically proved to be pulmonary adenocarcinoma were included in this study. All patients were divided into early surgery group (ES Group) (210 cases) and surgery after follow-up group (FS Group) (69 cases). Patients in FS group experienced at least one year surveillance. Clinical and imaging features were analyzed by using univariate analysis. After analysis, there was no statistical difference in pathological results and long-term prognosis between the two groups. In the follow-up group, grown GGNs have proved to have more aggressive pathological results. The one-year follow-up may be a feasible management method for patients with ground-glass component predominant GGN.
