The purpose of this study was to investigate whether surgical treatment for non-small cell lung cancer (NSCLC) confers a survival benefit in octogenarians, and whether video-assisted thoracic surgery (VATS) is effective in terms of postoperative morbidity, mortality, and quality of life (QOL). Among 1684 patients with primary NSCLC who underwent pathologically complete resection, 95 were octogenarians. Operation was performed by the VATS approach (VATS group, n=58) or the standard thoracotomy (ST group, n=37). Although postoperative cardiopulmonary complications occurred in 20 cases (21.1%), all were manageable. In the ST group cardiopulmonary complications occurred more frequently than in the VATS group (P=0.030). The overall 5-year survival rate of the 95 octogenarians, including deaths from all causes, was 54.4%. The overall 5-year survival rate of patients with stage IA disease was 65.2%. These outcome data were not significantly worse than those for patients aged 79 years or under (P=0.136). There was no significant difference in overall 5-year survival rates between the ST group and the VATS group (P=0.144). The VATS approach for pulmonary resection is recommended for octogenarians with NSCLC. Surgical resection is the optimal treatment for stage IA NSCLC, and therefore, advanced age is not a contraindication for curative resection.
