title: [Extended operation for lung cancer: concomitant resection of the heart or the great vessels with the lung].
abstract: We have analysed our experience in 43 patients with lung cancer invading the heart or great vessels who underwent surgical resection of the invaded portion of the mediastinal organs as well as the primary tumor, and have reviewed the literature on the subject of the extended operation for lung cancer invading the heart or great vessels. Among our experience of those 43 patients, a single mediastinal organ was resected in 32 patients (the left atrium in 20, the main pulmonary artery in 7, superior vena cava in 3 and the adventitia of the aorta in 2), and more than two mediastinal organ were resected in 11 patients (the main pulmonary artery and the other in 8, and the left atrium and esophagus or trachea in 3). There were 34 squamous cell carcinomas, 4 adenocarcinomas, 3 large cell carcinomas and 3 other cell types. Pathology disclosed 6 patients had pT 3 tumor (Group 1, 24 patients had pT 4 tumor that had invaded to a single mediastinal organ (Group 2) and 11 patients had pT 4 tumor that had invaded to more than two mediastinal organs (Group 3). The 5 year survival rate in patients of Group 1, 2 and 3 were 80%, 32.2% and 0%, respectively. There were statistical differences among the survivals of those three groups. We conclude that extended resection for lung cancer invading the heart or great vessels is justified if the invasion is limited to a single mediastinal organ. Several problems on such extended resection were discussed.
