[Results of resection of T3 primary lung cancer].
Primary resection for lung cancer was performed in 711 patients. Extensive surgery was performed in 99 T3 lung cancer (13.7%). Overall 5-year survival rate was 31.7%. Overall hospital mortality was 7.5%. Mean 5-year survival was 34.9% for patients with complete resection, 0% for patients with incomplete resection (p < 0.05). In patients with complete resection, mean 5-year survival was greater in patients with N0 (39.1%) than in patients with N1 (23.5%) or N2 (27.7%), but there was no statistically significant difference. There was also no statistically significant difference between adenocarcinoma and squamous cell carcinoma. Mean 5-year survival rate for patients with invasion of chest wall was 34.1%, with invasion of mediastinal pleura was 37.5%, with invasion of main bronchus was 58.3%, with interlobular invasion was 18.7%. Complete resection of T3 lung cancer may yield long time survival.
