[Surgical Treatment of T3 Lung Cancer with Invasion of Chest Wall and Other Adjacent Organs].

We conducted a retrospective investigation in patients who underwent surgery for T3 lung cancer with invasion of chest wall and other adjacent organs. Fifty patients who underwent surgery for T3 lung cancer with invasion of adjacent organs were investigated. The chest wall was the most frequently invaded organ, followed by the pericardium and mediastinal pleura. In cases of chest wall invasion, patients underwent en bloc resection and, when a complete resection was judged feasible, extrapleural resection. Six patients with superior sulcus tumor underwent surgery after preoperative treatment. The 5-year-survival was 55.7%. A significant difference in 5-year survival was observed between complete resection and incomplete resection in patients with lung cancer with chest wall invasion( p<0.047).
