Use of heterogenous and monospecific antisera for the diagnosis of bladder cancer.
A rabbit antibody to antigens present in urine from bladder cancer patients was prepared and used in conjunction with various monospecific antisera to detect urine components related to bladder cancer. All urine samples were centrifuged routinely, dialyzed and concentrated 10 times before assay by gel diffusion versus the various antisera. Urine was considered positive when it showed reactivity with 2 or more antibodies. This method of analysis resulted in the diagnosis of 64% of the bladder papillomas and 77% of the bladder cancers tested, compared to only a 7% falsely positive rate with normal urine. These data support the potential usefulness of an antiserum panel in the immunological diagnosis of bladder cancer in the general population and in high risk individuals.
