Objective: The purpose of this study was to evaluate the clinical significance of video-assisted thoracoscopic lobectomy (VATS lobectomy) for primary lung cancer. Method: From April 1995 to December 2000, 98 patients with non-small cell lung cancer underwent VATS lobectomy in our institution. Of these patients, 80 were classified as cIA, 13 as cIB, 2 as cIIA, 2 as cIIIA, and 1 as cIIIB. The pathological stages were IA in 65 patients, IB in 18, IIA in 4, IIB in 3, IIIA in 7, and IIIB in 1. The clinical outcome of these patients was compared with that of open thoracotomy performed during the same period. Results: Three-year survival rates of VATS lobectomy and open thoracotomy for cIA lung cancer were 91.7% and 73.0%, respectively. The outcome of VATS lobectomy was significantly better compared with thoracotomy (p=0.02). There were no differences in 3-year disease free survival in all cIA lung cancer patients, even in cIA lung cancer 2 cm or more in diameter. The operation time of VATS lobectomy was 183.7± 52.5 minutes (95-330) and the intraoperative blood loss was 203.9± 230.0 ml (15-1345). Postoperative hospital stay was significantly shorter in VATS lobectomy (10.8± 4.1 days; p<0.0001). Conclusion: The prognosis of VATS lobectomy for cIA lung cancer was equivalent to thoracotomy. We concluded VATS lobectomy could be the standard treatment for cIA lung cancer.
