Pulmonary resection for lung cancer in nonagenarians: a report of five cases.

Lung cancer surgery in octogenarians has already become common in Japan due to the high proportion of elderly people and the progress in perioperative management, including anesthesia and video-assisted thoracic surgery. However, there have been few reports about the surgical treatment of lung cancer in nonagenarians. Five cases (mean age: 91.2 years; 3 men, 2 women) of non-small cell lung cancer in nonagenarians in whom pulmonary resection was performed are reported. All were adenocarcinomas; three were clinical stage IA, and two were IB. Three patients underwent lobectomy, and two underwent wedge resection. Mediastinal lymph node dissection was omitted in all patients. There were no fatal postoperative complications. During follow-up, one patient died due to fatal arrhythmia, and one patient who underwent wedge resection had local recurrence, but the others are alive in good condition. Pulmonary resection of lung cancer is possible for highly selected, nonagenarian patients without lymph node metastasis.
