What is Long-term Outcome of Bladder Papillary Urothelial Neoplasms of Low Malignant Potential about?

## OBJECTIVE To evaluate the long‐term outcome of bladder papillary urothelial neoplasms of low malignant potential (PUNLMP). ## PATIENTS AND METHODS Of 475 consecutive patients with newly diagnosed bladder tumours between 1976 and 1993, 330 (69%) had superficial (Ta and T1) tumours and 53 (11%) were diagnosed as having PUNLMP. Fifty patients (mean age at presentation 57.2 years, range 26–83; male‐to‐female ratio 6 : 1) who were followed for> 5 years or until they died, were included in the present study. All histological slides were reviewed, and fulfilled the diagnostic criteria of the 1998 World Health Organization/International Society of Urological Pathology classification system. ## RESULTS The mean (median, range) follow‐up was 11.7 (10.8, 1.3–24.4) years. During the follow‐up, 30 patients (60%) had local recurrences. The 2, 5 and 10‐year recurrence‐free rates were 66%, 51% and 36%, respectively. No patients developed high‐grade or muscle‐invasive (≥ T2) carcinomas, or upper urinary tract tumours, or died from the disease. At the last follow‐up, 34 patients (68%) had been disease‐free for> 5 years. ## CONCLUSIONS Despite a high recurrence rate, PUNLMP carries a very low mali
