The aim of this study was to evaluate our personal experience with video-assisted thoracoscopic lobectomy and compare survival between this procedure and conventional lobectomy via open thoracotomy in patients with clinical stage IA non-small cell lung carcinoma. Between May 1997 and December 2004, 140 patients with clinical stage IA non-small cell lung carcinoma had either VATS lobectomy (VATS group, 84 patients) or standard lobectomy via open thoracotomy (open group, 56 patients) performed in our hospital. We compared overall survival, disease-free survival and recurrence between the two groups. The overall survival rate five years after surgery was 72% in the open group and 82% in the VATS group. There were no significant differences in the overall survival rate between the two groups. The disease-free survival rate five years after surgery was 68% in the open group and 80% in the VATS group. There were no significant differences in the disease-free survival rate between the two groups. Five patients in the open group developed distant recurrence, whereas one patient developed regional recurrence. In the VATS group six patients developed distant recurrence, whereas one patient developed regional recurrence. We consider VATS lobectomy to be one of the therapeutic options in patients with clinical stage IA non-small cell lung carcinoma.
