Multiple primary tumours of the urogenital system: Our cases and a review of the literature

Abstract

We had 6 genitourinary tumour patients with other primary tumours in a 147 genitourinary tumour patient group. Two of these tumours developed synchronously while the others were metachronous, and two of them developed in the genitourinary system. It is clear that cancer patients have a higher risk of a second cancer than the general population. Second cancers may be detected in long-term follow-up of cancer patients, or may be caused by the aetiologic factor(s) with pleiotropic effects, or may develop because of the therapies for the first cancer.

Evaluation of secondary cancers, synchronous and metachronous with bladder cancer

“…In the study of Özdamar et al 36 on 147 patients with genitourinary tumors, 6 patients had another tumor, 2 of which were concomitant and 4 of which were asynchronous. Cancer patients are at higher risk of secondary cancer than the general population.…”
