[Therapeutic results after resection of asymptomatic lung cancer]

This article reported a group of 43 cases of lung cancer who had no symptoms before resection, and were detected by mass screening or routine physical examination. They accounted for 15.2% of 282 cases undergoing lung cancer resection during the periods from January, 1977 to June, 1990 in our hospital. Pathologic study of the resected specimens showed that there were 32 cases of Stage I lung cancer (74.4%). Among them 15 cases were of early stage (T1N0M0) which accounted for 5.3% of 282 cases. 5-years survival rate of this subgroup was 81.8%. About one fourth of asymptomatic lung cancer belonged to middle or late stage.
