Abstract

Lung function tests were performed in 114 patients with primary lung cancer which were confirmed histopathologically at Chonnam University Hospital from August 1981 to July 1988. Ten cases (8.8%) showed norrnal lung function, 19 (16.7%) pure restrictive lung disease, 75 (65 .8%) moderate obstructive lung disease, and 10 (8.8%) severe obstructive lung disease FEV₁/ FVC was higher in small cell cancer than in non-small cell cancer, lower in heavy smoker, and there was a tendency for non-small cell cancer to have heavy smokers. FEV₁ was lower in central type than in peripheral type, not different between obstructive and stenotic, and lower in obstruction of right main bronchus than left one. There was no difference in lung function according to anatomic stage but according to physiologic stage. Among the localized lung cancer, cases with FEV₁ more than 2.5 L were 1/ 3 in small cell cancer and 16.7% in non-small cell cancer.
