Surgical treatment for patients older than 70 years was gradually increased.Limited resection has done in 24 cases, and video-assisted techniques were performed in some cases. Histological diagnoses were adenocarcinoma in 324 cases,squamous cell carcinoma in 209 cases and others in 37 cases.Almost 60% of all 570 cases were pathological stage I disease,and the rate gradually increased.The average tumor size of all resected cases was 33.8mm,and cases with tumor size within 20mm increased,reaching half of cases in recent years. In the evaluation of the relationship between tumor size and lymph node metastasis,cases with tumor size within 10mm had no metastasis and the positive rate was higher according to the size.The 5-year survival rate in stage IA disease was 76.7%, reaching statistically significant differences compared with other stages. It was suggested that small-sized early disease was gradually increased in the resected cases of lung cancer. Although limited resection for early stage lung cancer remains controversial, a reliable alternative limited surgical procedure for selected patients with early disease will be necessary in the near future., Article, 信州医学雑誌 48(4): 243-248(2000)}, pages = {243--248}, title = {教室における肺癌切除例の検討}, volume = {48}, year = {2000} }
