Abstract | PURPOSE: MATERIALS AND METHODS: RESULTS: Mean urinary bladder cancer antigen concentrations were 104.84, 4.57, 11.79, 48.87 and 1.38 microg/l, for groups 1 to 5, respectively, which was statistically different (p = 0.00005) except for groups 1 and 4 (p = 0.187). Sensitivity was 87.0% (95% confidence interval 79.2 to 92.7) and specificity was 86.8% (77.1 to 93.5%), and both were optimized by receiver operating characteristics plot analysis at a threshold value of 9.74 microg/l using asymptomatic (group 2) compared to known cancer (group 1) cases.
