Brief Summary

To assess whether the addition of a bladder tumor biopsy improves the level of agreement between the pretreatment endoscopic impression and the final postoperative pathology determination of stage and grade in non-muscle-invasive urothelial carcinoma of the bladder.

Detailed Description

Non-invasive bladder cancer is challenging to treat because it is a condition characterized
by frequent recurrences that lead to numerous invasive procedures for detection and
treatment. The mainstay of therapy for non-muscle invasive bladder cancer, which has remained
unchanged for decades, relies on surgical resection (TUR) associated with utilization of
intravesical immunotherapy and chemotherapy. Despite our best efforts, these tumors continue
to have suboptimal rates of recurrence and require long-term follow-up with costly and
invasive procedures. The rationale for this study is to show that the preoperative biopsy,
taken at the time of the office cystoscopic evaluation, improves pre-TUR staging and grading
correlation with the final pathology of the resection. Indirectly, this will suggest that the
routine use of pre-TUR biopsy provides more accurate information for intraoperative
decision-making that can ultimately lead to better management of these patients with
non-muscle-invasive bladder cancer.
