Abstract
BackgroundAlthough minimally invasive lobectomy has gained worldwide interest, there has been debate on perioperative and oncological outcomes. The purpose of this study was to compare outcomes among open lobectomy, video-assisted thoracic surgery lobectomy, and robotic lobectomy. MethodsPubMed, EMBASE, and Web of Science databases were consulted. A fully Bayesian network meta-analysis was performed. ResultsThirty-four studies (183,426 patients) were included; 88,865 (48.4%) underwent open lobectomy, 79,171 (43.2%) video-assisted thoracic surgery lobectomy, and 15,390 (8.4%) robotic lobectomy. Compared with open lobectomy, video-assisted thoracic surgery, lobectomy and robotic lobectomy had significantly reduced 30-day mortality (risk ratio = 0.53; 95% credible intervals, 0.40–0.66 and risk ratio = 0.51; 95% credible intervals, 0.36–0.71), pulmonary complications (risk ratio = 0.70; 95% credible intervals, 0.51–0.92 and risk ratio = 0.69; 95% credible intervals, 0.51–0.88), and overall complications (risk ratio = 0.77; 95% credible intervals, 0.68–0.85 and risk ratio = 0.79; 95% credible intervals, 0.67–0.91). Compared with video-assisted thoracic surgery lobectomy, open lobectomy, and robotic lobectomy had a significantly higher total number of harvested lymph nodes (mean difference = 1.46; 95% credible intervals, 0.30, 2.64 and mean difference = 2.18; 95% credible intervals, 0.52–3.92) and lymph nodes stations (mean difference = 0.37; 95% credible intervals, 0.08–0.65 and mean difference = 0.93; 95% credible intervals, 0.47–1.40). Positive resection margin and 5-year overall survival were similar across treatments. Intraoperative blood loss, postoperative transfusion, hospital length of stay, and 30-day readmission were significantly reduced for minimally invasive approaches. ConclusionCompared with open lobectomy, video-assisted thoracic surgery lobectomy, and robotic lobectomy seem safer with reduced 30-day mortality, pulmonary, and overall complications with equivalent oncologic outcomes and 5-year overall survival. Minimally invasive techniques may improve outcomes and surgeons should be encouraged, when feasible, to adopt video-assisted thoracic surgery lobectomy, or robotic lobectomy in the treatment of lung cancer.
