[Three cases of double cancer: genitourinary and lung cancers]

Abstract

Three patients who had genitourinary cancer combined with lung cancer are reported. One patient had pulmonary adenocarcinoma and bladder transitional cell carcinoma, one had small cell lung cancer and squamous cell carcinoma of the penis, and one had large cell lung carcinoma and prostatic adenocarcinoma. In Japan, where society is aging rapidly, cases of multiple primary cancer with lung and genitourinary cancers are expected to increase considerably in the future.
