Implementing a Checklist for Transurethral Resection of Bladder Tumor to Standardize Outcome Reporting: When High-quality Resection Could Influence Oncological Outcomes.

Unlabelled: Several randomized controlled trials (RCTs) comparing en bloc resection of bladder tumor (ERBT) to conventional transurethral resection of bladder tumor (cTURBT) have reported controversial results. In particular, the 1-yr recurrence rate ranged from 5% to 40% for ERBT and from 11% to 31% for cTURBT. We provide an updated analysis of an RCT comparing the 1-yr recurrence rate for ERBT versus cTURBT for a cohort of 219 patients comprising 123 (56.2%) in the ERBT group and 96 (43.8%) in the cTURBT group. At 1 yr, 11 patients in the ERBT group and 12 in the cTURBT group experienced recurrence. The heterogeneity in recurrence observed in other RCTs could be explained by the scarce and heterogeneous adoption of tools and techniques that have been proved to lower the recurrence rate, supporting the need for implementation of a TURBT checklist. This prompted us to create a checklist of items for RCTs to standardize how TURBT is performed in trials, facilitate comparison between studies, assess the applicability of results in real-life practice, and provide a push towards high-quality resections to improve oncological outcomes. The checklist could have utility as a user-friendly guide for reporting TURBT procedures to improve our understanding of trials involving this procedure.

Patient Summary: We compared the recurrence rate at 1 year for bladder cancer treated with two different approaches to remove bladder tumors in our center. The rates were comparable for the two groups. Other studies have found widely differing recurrence rates, so we propose use of a checklist to standardize these procedures and provide more consistent outcomes for patients.
