p16/CDKN2 gene and p53 gene alterations in Japanese non-smoking female lung adenocarcinoma.

Primary lung adenocarcinomas in non-smoking females are increasing in the USA and Japan. Environmental factors such as passive smoking, asbestos, domestic radon, and hormonal effects have been implicated, but the etiology is still uncertain. We therefore analyzed point mutations of p16 gene, a newly characterized tumor suppressor gene, and compared the results with alterations of p53 gene in 28 primary lung adenocarcinomas in non-smoking Japanese females.

A 68-year-old man was referred because of an abnormal shadow in the right upper lung field on a chest X-ray film. After the diagnosis of adenocarcinoma of the lung, left upper lobectomy was done. Histologically, adenocarcinoma with foci of squamous cell carcinoma was seen.
