Long-term survival of thoracoscopic surgery compared with open surgery for clinical N0 adenocarcinoma

BACKGROUND: Early stage non-small cell lung cancer (NSCLC) is good candidate for video-assisted thoracoscopic surgery (VATS). Long-term outcome compared between VATS and open surgery remains unclear. The aim of this study was to assess the long-term outcome of VATS in early stage adenocarcinoma. MET...

Sumario:BACKGROUND: Early stage non-small cell lung cancer (NSCLC) is good candidate for video-assisted thoracoscopic surgery (VATS). Long-term outcome compared between VATS and open surgery remains unclear. The aim of this study was to assess the long-term outcome of VATS in early stage adenocarcinoma. METHODS: A retrospective study was performed in 546 patients which were operated between January 2006 and December 2010 in our institute and of those, 240 (220 lobectomies, and 20 segmentectomies) were clinical N0 adenocarcinoma. One hundred and thirty-five patients underwent VATS and 105 patients for open surgery. Long-term oncological outcomes were compared in both groups. RESULTS: There were significant differences in age, gender, Blinkman index, clinical T factor and tumor size between two groups. VATS group showed statistically longer operation time (P=0.01), less blood loss (P=0.005), shorter length of stay (P=0.001), and less dissected number of lymph nodes (P<0.001) compared with open surgery. Disease-free survival in VATS was significantly better than open surgery (5- and 10-year survival; VATS, 91.4%, 79.0%; open, 85.1%, 73.6%; respectively, P=0.04). Overall survival in VATS was not different from open (P=0.58). Propensity matched disease-free and overall survival was not significantly different between two groups. Multivariate Cox regression analysis showed that age [P=0.04, 95% confidence interval (CI): (1.02–6.81)] in overall and T factor [P=0.01, 95% CI: (1.41–17.3)] in disease-free survival was prognostic significant after propensity matching. CONCLUSIONS: Our study demonstrated that long-term outcome in VATS for early stage adenocarcinoma was equivalent to open surgery. VATS may be a treatment of choice for promising long-term prognosis.
