Summary:Fifty-seven patient with pT1N0M0 non-small cell lung cancer underwent pulmonary resection at Ishikawa Prefectural Central Hospital between 1982 and 1993. The results of treatment were assessed retrospectively. The overall 5-year survival rate was 91%. In 39 patients with adenocarcinoma it was 84%, and in 15 patients with squamous cell carcinoma it was 100%. Cancer recurred in 18% of adenocarcinoma patients after absolute curative resection. There were significant differences in survival rates between patients with well differentiated and moderately differentiated adenocarcinoma, and between those with moderately differentiated and poorly differentiated adenocarcinoma. The diameter of the adenocarcinoma was also related significantly to lenght of survival (less than 20 mm versus 21-30 mm). We conclude that postoperative chemotherapy is important for 21-30 mm or poorly differentiated adenocarcinoma.
