[Postoperative recurrence of the patients with the stage I, II non small cell lung cancer].
The study population consisted of 42 patients with squamous cell carcinoma and 46 patients with adenocarcinoma of stage I, 12 patients with squamous cell carcinoma and 7 patients with adenocarcinoma of stage II lung cancer who underwent curative surgical resection. Local recurrence and metastasis was not significant in both histological types in stage I, II. Lung and bone metastasis was dominant in the both cases of squamous cell carcinoma, adenocarcinoma and brain metastasis in the cases of adenocarcinoma. Concerning the period to first recurrence following the operation, the recurrences of stage I squamous cell carcinoma occurred 28% within 1 year after surgery, 28% during 1-2 years after surgery and those of stage II squamous cell carcinoma occurred 11% within 1 year. On the other hand, the recurrences of stage I adenocarcinoma occurred 25% within 1 year, 31% during 1-2 years, 25% over 2 years after surgery and those of stage II adenocarcinoma occurred 13% within 1 year. In the cases with squamous cell carcinoma, the 5-year survival rate (56%) of stage I was not significant compared with those (59%) of stage II. On the other hand, in the adenocarcinoma, the 5-year survival rate (54%) of stage I was significantly better than those (29%) of stage II (p less than 0.05).
