Can fewer bladder cancer procedures be just as effective?
This Bladder Cancer Awareness Month highlights a national clinical trial led by Dartmouth Cancer Center researcher Florian R. Schroeck, MD, which is testing whether patients with high-grade bladder cancer can safely undergo fewer invasive surveillance procedures after treatment.
Current guidelines recommend cystoscopy (a procedure that uses a camera to examine the bladder), every three to four months for years after treatment. While effective, the procedure can be uncomfortable and burdensome.
Conducted through the U.S. Department of Veterans Affairs (VA), and with plans to expand to more than 30 VA sites nationwide, the study will follow patients over 10 years, comparing standard surveillance with a lower-intensity approach that relies more heavily on non-invasive urine testing.
Schroeck's team hopes the strategy could cut the number of invasive procedures by more than half without affecting survival or cancer outcomes. “The goal is not to reduce care, but to refine it,” he says.
