A clinical study was conducted on 22 patients aged less than 40 years old who underwent resection for lung cancer in our department. They were 14 men and 8 women. Their mean age was 34.2 years old and the youngest patient was a 23-year-old woman. There were 12 (55%) asymptomatic cases and 10 (45%) symptomatic cases. Histological types were adenocarcinoma in 12 cases, squamous cell carcinoma in 2 cases, large cell carcinoma in 1 case, small cell carcinoma in 4 cases and carcinoid in 3 cases. Small cell carcinoma and carcinoid were more commonly found than in the over 40-year-old resected group. There were 9 stage I cases, 4 stage II, 7 stage IIIA, 1 stage IIIB and 1 stage IV, according to pathological examinations, thus 90% of the patients were in stage I+II+IIIA. All cases detected by mass screening were stage I+II+IIIA. The prognosis of patients less than 40 years old did not differ significantly from that of the over 40-year old resected group with a 5-year survival rate.
