      A group of 108 male workers previously exposed to bladder carcinogens and a group of 26 patients with carcinoma of the bladder differed significantly from a control group comprising 63 healthy male donors with respect to their levels of tissue polypeptide antigen (TPA). The risk group exhibited 4-6 times more frequent elevations of TPA than did the group of healthy donors.
