From 1972 to 1990, a total of 173 early stage lung cancer cases (67 central type and 106 peripheral type) were treated surgically at our institute.<BR>Recently increasing numbers of early stage lung cancers are being detected, which increases the rate of resectability. Seventy percent of central early lung cancer cases and 87% of peripheral lung cancer cases were detected via mass surveys.<BR>While 97% of central early lung cancers were squamous cell carcinoma and 3% adenocarcinoma, 72% of peripheral lung cancers were adenocarcinoma, 24% squamous cell carcinoma and 4% other cell types. The postoperative 5-year and 10-year survival rates were 82%, 54% for all early stage lung cancers, 76%, 42% in central early lung cancer and 86%, 64% in peripheral early lung cancer.<BR>In many cases, patients postoperatiyely died of another cancer in other organs. Observation is needed for detection of a second cancer.
