Background Although the frequency of elderly patients undergoing surgery for lung cancer has been increasing, indications for surgery in elderly patients are still controversial. Low body mass index is a significant predictor of poor prognosis in elderly patients with various medical conditions. Then, we examined the long-term outcome of elderly patients who had undergone thoracic surgery for lung cancer, focusing especially on body mass index. Patients and methods Between January 2004 and March 2011, 1673 patients with lung cancer underwent surgical resection at our institution. Among these patients, we retrospectively examined 158 patients aged 80 years or older. Results Perioperative morbidity and mortality rates were 41.8 and 1.3%, respectively. Among 149 patients who were completely followed up, 80 patients (53.7%) died. The overall postoperative survival rates at 3 and 5 years were 66.9 and 49.9%, respectively. Univariate analysis demonstrated that sex (female), smoking index (pack-years
