Abstract
ABH antigenicity of mucosal biopsies was studied in 36 patients with superficial bladder cancer. Those with mucosal biopsies positive for antigen had a recurrence rate of 0.33 recurrences per year, compared to 1.97 in those negative for antigen. This difference was highly significant on statistical analysis. ABH antigenicity of mucosal biopsies proved to be a better predictor of recurrent disease than other prognostic indexes, such as number, size, histological grade and ABH antigenicity of primary tumors, as well as histological status of the mucosal biopsies.
