The main surgical procedures were lobectomy in 124 patients, segmentectomy in 37, and wedge resection in 47 patients. The 3-year overall survival (OS) rate was 63.6%, and the median OS was 46.5 months. A multivariate analysis identified male sex and reduced vital capacity as independent predictors of a poor survival. In clinical stage I patients, wedge resection was associated with a poorer survival than anatomical resection, although the baseline characteristics differed between the groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Pulmonary resection may be feasible in carefully selected super-elderly patients.
