The recent classification of Merkel cell polyomavirus (MCV) infection as probably carcinogenic and of BK virus (BKV) and JC virus (JCV) infections as possibly carcinogenic suggests that these agents may play a role in the development of certain malignancies. In this evaluation, which focused on bladder cancer specifically, disease was found to be associated with high seroreactivity for BKV and MCV but not JCV. There was no association of seroreactivity with disease stage or grade. The results suggest that urothelial cell carcinoma, the most common type of bladder cancer in industrialized countries, may have an infectious etiology.
