The recent incidence of lung cancer in young adults was evaluated through the Annual of the Pathological Autopsy Cases in Japan. Although the absolute number of lung cancer cases in young adults has been increasing, the relative rate has been decreasing because of the greater number of lung cancer patients aged more than 40.<BR>A clinical study of 48 lung cancer cases aged less than 40, constituting 4.2% of 1141 patients with lung cancer, was carried out. They consisted of 26 males and 22 females. Of these 39 were adenocarcinoma, 5 were epidermoid carcinoma, 2 were small cell cancer and 2 were large cell cancer.<BR>The number of cigarette smokers was 21, including 8 heavy smokers. This suggests that the relationship between lung cancer in young adults and cigarette smoking may not be significant. Over 80% of the 48 patients were advanced lung cancer. This problem may be related to the facts that the period between initial symptom and first visiting a chest physician was long and that some cases were misdiagnosed as pulmonary tuberculosis and treated by antituberculosis drugs for some months. In spite of the advanced stage their perofrmance status was not poor. If they had been diagnosed as lung cancer in an early phase, all of them could have received successful surgical treatment.<BR>The median survival time of the young adult cases with lung cancer was 10 months and there was no difference concerning the survival between young adults and cases over 40 years old.
