Ninety-four patients with T1NOMO peripheral lung cancer were operated upon in our hospital from 1970 through 1985.<BR>The 5-year survival rates were 76.3% for the entire group, 75.5% for the adenocarcinoma group, and 78.6% for the epidermoid carcinoma group.<BR>For the curative operation group, the 5-year survival rate was 83.2% and significantly better than that for the non-curative operation group. Patients with tumors less than 15 mm in diameter all received curative operations and had a 5-year survival rate of 100% which was significantly better than that for patients with tumors more than 16 mm in diameter. Patients over 70 years old had a low survival rate of 48.9%. However, in the curative operation group, no significant difference was noted in survival rates between the older and younger groups.<BR>Recurrences were noted in 20 patients during the follow-up period of 7-79 months, in 6 cases of adenocarcinoma later than 60 months postoperatively.
