Abstract

Introduction: Renal tumour biopsies (RTBs) can provide the histology of small renal masses (SRMs) prior to treatment decisionmaking. However, many urologists are reluctant to use RTB as a standard of care. This study characterizes the current use of RTB in the management of SRMs and identifies barriers to a more widespread adoption.

Methods: A web-based survey was sent to members of the Canadian and Quebec Urological Associations who had registered email address (n=767) in June 2016. The survey examined physicians’ practice patterns, RTB use, and potential barriers to RTB. Chi-squared tests were used to assess for differences between respondents.

Results: The response rate was 29% (n=223), of which 188 respondents were eligible. A minority of respondents (12%) perform RTB in >75% of cases, while 53% never perform or perform RTB in <25% of cases. Respondents with urological oncology fellowship training were more likely to request a biopsy than their colleagues without such training. The most frequent management-related reason for not using routine RTB was a belief that biopsy won’t alter management, while the most frequent pathology-related reason was the risk of obtaining a false-negative or a non-diagnostic biopsy.

Conclusions: Adoption of RTBs remains low in Canada. Concerns about the accuracy of RTB and its ability to change clinical practice are the largest barriers to adoption. A knowledge translation strategy is needed to address these concerns. Future studies are also required in order to define where RTB is most valuable and how to best to implement it.
