Urothelial papilloma is generally viewed as a benign bladder tumour with low risk of progression to bladder cancer.
Your pathology report sounds quite benign, but the presence of focal intestinal metaplasia tells us that the bladder lining is not 100% normal, and should certainly be followed up with cystoscopic surveillance. The frequency of cystoscopic surveillance depends on the urologist, although we generally recommend yearly follow-ups for at least 2-3 years.
The group from the Singapore General Hospital reported their experience of 52 patients with bladder papilloma - none developed bladder cancer after cystoscopic surveillance after a mean period of 5 years save one.
Sincerely,
Dr Ash Tewari, MD

Are you able to respond to this request regarding bladder cancer?
