Abstract
BACKGROUND:
To compare the outcomes and costs of two methods of video-assisted thoracoscopic surgery (VATS) major pulmonary resection in patients with clinically resectable non-small cell lung cancer (NSCLC).
METHODS:
Between January 2000 and December 2007, 1,058 patients with proven stages I-IIIA NSCLC underwent complete VATS (c-VATS) or assisted VATS (a-VATS) major pulmonary resection together with a systematic nodal dissection.
RESULTS:
The study cohort consisted of 736 men and 322 women. Mean operative time was shorter for the a-VATS cohort compared with the c-VATS group (P = 0.038). Overall survival (OS) at 5 years based on Kaplan-Meier analysis was 55.3% (95%CI, 50.6-60.0%) for those who underwent c-VATS and 47.7% (95%CI, 41.2-54.2%) for those who underwent a-VATS (P = 0.404). Gender, final pathology, TNM stage, and pT status were significant predictive factors for OS according to multivariate analysis. The total cost of a-VATS lobectomy was lower than that of c-VATS lobectomy.
CONCLUSIONS:
c-VATS and a-VATS yield similar results in patients with clinically resectable NSCLC. a-VATS, however, may be less expensive and easier to adopt, making it a particularly attractive option for thoracic surgeons in developing countries.
