Screening methods in the detection of bladder cancer : comparison of nuclear matrix protein-22, bladder tumor antigen and cytological examinations

We evaluated the utility of urinary parameters (Nuclear Matrix Protein-22: NMP-22, Bladder Tumor Antigen: BTA, and cytological examinations) for the diagnosis or post-therapeutic monitoring of bladder cancer. Thirty one tumor-bearing cases including 19 fresh cases and 40 tumor-free cases, were subje...

520 |a We evaluated the utility of urinary parameters (Nuclear Matrix Protein-22: NMP-22, Bladder Tumor Antigen: BTA, and cytological examinations) for the diagnosis or post-therapeutic monitoring of bladder cancer. Thirty one tumor-bearing cases including 19 fresh cases and 40 tumor-free cases, were subjects of this study. Using identical voided urine samples, NMP-22, BTA and urinary cytology were examined. The mean values of NMP-22 (cut-off value is 12 U/ml) was 100.5 +/- 26.5 U/ml in the tumor-bearing group and 21.9 +/- 7.8 U/ml in the tumor-free group (p < 0.05): Sensitivity was 74.2%, and specificity was 67.5%. Sensitivity of BTA was 58.1%, and specificity was 97.5%. Only five cases were judged positive by urinary cytology: 16.1% in sensitivity and 100% in specificity. Thus, NMP-22 and BTA were more sensitive than urinary cytology. In conclusion, the new urinary parameters, NMP-22 and BTA, would be less invasive and useful as tumor markers of bladder cancer. NMP-22 seems suitable for screening before the diagnosis and BTA for the post-therapeutic follow-up study
