PURPOSE: The current randomized trials comparing video-assisted thoracic surgery (VATS) lobectomy with open lobectomy for patients with early-stage non-small-cell lung cancer (NSCLC) have been of small size. We performed the present meta-analysis of the randomized and nonrandomized comparative studies in an attempt to assess the safety and efficacy of VATS lobectomy. METHODS: Electronic searches identified 21 eligible comparative studies (two randomized and 19 nonrandomized) for inclusion. Two reviewers independently appraised each study. Meta-analysis was performed by combining the results of reported incidence of morbidity and mortality, recurrence, and 5-year mortality rates. The relative risk (RR) was used as a summary statistic. RESULTS: There were no significant statistical differences between VATS and open lobectomy in terms of postoperative prolonged air leak (P = .71), arrhythmia (P = .86), pneumonia (P = .09), and mortality (P = .49). VATS did not demonstrate any significant difference in locoregional recurrence (P = .24), as compared with the open lobectomy arm, but the data suggested a reduced systemic recurrence rate (P = .03) and an improved 5-year mortality rate of VATS (P = .04). There was no evidence to suggest heterogeneity of trial results. Fourteen studies reported VATS to open lobectomy conversion rate ranging from 0% to 15.7% (median = 8.1%). CONCLUSION: Both randomized and nonrandomized trials suggest that VATS lobectomy is an appropriate procedure for selected patients with early-stage NSCLC when compared with open surgery.
