title: Video-assisted thoracic surgery for lung cancer: is it a feasible operation for stage I lung cancer?
abstract: OBJECTIVE
  The objective of this study was to confirm the safety and feasibility of video-assisted thoracic surgery (VATS) for primary lung cancer and to compare prognoses with that of conventional procedures, and then to examine whether VATS would supplant a conventional thoracotomy for stage I lung cancer.
  
  
  METHODS
  From September 1995 through March 2002, 144 patients with primary lung cancer, included 118 patients with postoperative stage I, underwent VATS lobectomy. We reviewed the previous cases whether they could be candidates for VATS lobectomy according to present indications. 166 cases were supposed to be candidates for VATS, and 121 cases of postoperative stage I disease were recruited into the "conventional thoracotomy" group.
  
  
  RESULTS
  There was no mortality or major complication except one case, and mean follow-up was 31.8 months in VATS. The number of removed lymph nodes was not significantly less than the number by conventional thoracotomy (p=0.061). Five-year survival for patients with pathological stage IA adenocarcinoma was 92.4% (n=66) in VATS and 86.9% (n=50) in conventional thoracotomy, and a statistical significance could not be recognized (p=0.980). The length of hospital stay was significantly short in VATS lobectomy (p<0.0001).
  
  
  CONCLUSIONS
  VATS lobectomy for stage I lung cancer can be performed safely with minimal morbidity, satisfying survival comparable with that of lobectomy through conventional thoracotomy. VATS approach is a feasible surgical technique for patients with stage I lung cancer.
