Although several causes of false positive results have been identified, the clinical value of positive NMP22 is often doubtful. We present the long term outcome of patients in follow-up for previous NMI bladder cancer presenting with NMP elevated values in spite of negative cytology, cystoscopy and urography. METHODS A urine collection kit, containing urine stabilizer and a test kit using MAb302-18 and MAb302-22, developed by Matritech Inc. was used. Urine samples were obtained in all patients after a single spontaneous void and frozen at -20°C immediately after collection. A cut-off value of 10 units/ml was adopted. A positive NMP22 was obtained in 95 patients in follow-up for Ta-T1 G1-3 bladder cancer. In 50 patients (53%) intravesical chemotherapy was given and urine was obtained after an interval of 7-30 days. Cytology, cystoscopy and urography were negative. No other urological pathology was evident except for asymptomatic BPH. Since 1996 all patients were maintained into a close follow-up with urinary cytology and cystoscopy every 3 months for the first 2 years and 6-monthly thereafter. All suspicious lesions at cystoscopy were biopsied. A bladder mapping was performed in the case of negative cystoscopy and positive or doubt cytology. RESULTS Median follow-up was 51 months (range: 2-174). Five patients only (5%) were lost at follow-up before 2 years and 3 patients died. The median interval between the last recurrence and NMP22 determination was 39 months. Thirty-seven (39%) patients recurred at a mean interval of 13 months from NMP22 test. No significant difference was evident in NMP22 levels between recurring and recurrence-free patients (p=0.26). The results were not influenced by intravesical chemotherapy (p=0.87). No clinically relevant difference emerged in recurrence-free survival according to NMP22 values higher or lower than 10 U/ml (38 vs 31 months) although statistically significant. CONCLUSIONS Positive urine NMP22 in patients in follow-up for previous NMI-BC is not associated with a higher risk of recurrence when accompanied by negative cytology and cystoscopy.
