title: [Primary multiple cancers related to urological malignancies].
abstract: In the course of 5 years, we encountered 11 cases of primary multiple cancers related to urological malignancies at the Department of Urology, Tokyo Metropolitan Komagome Hospital. The patient age at diagnosis of the first cancer ranged from 59 to 77 years (mean 69 years); there were 9 men and 2 women. Of patients with urological malignancies, 6.4% had multiple cancers. All cases were diagnosed clinically and diagnosis was confirmed histologically. In ten patients, second cancers were found within one year. Three cases were combined with urological cancers, six cases with gastric cancer. The clinical course of a patient with renal pelvic-ureteral cancer and gastric carcinoma is presented in detail.
