Urine Testing vs Cystoscopy for Bladder Cancer Surveillance
(ReplaceCysto Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if urine tests can replace some cystoscopy procedures for monitoring bladder cancer. It examines whether urine tests affect symptoms, discomfort, the number of invasive procedures, anxiety, complications, and cancer progression differently than regular cystoscopies. Participants are divided into groups receiving either urine tests (such as the Bladder EpiCheck urine test or the Xpert Bladder Cancer Monitor urine test) or more frequent cystoscopies. This trial suits individuals with a history of low-grade bladder cancer who have not experienced a recurrence in recent months. As an unphased trial, it offers the opportunity to contribute to innovative research that could enhance future bladder cancer monitoring methods.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that these urine tests are safe for bladder cancer surveillance?
A previous study demonstrated that the Bladder EpiCheck urine test accurately identified individuals with and without bladder cancer, suggesting its reliability and safety for patients.
Research on the Xpert Bladder Cancer Monitor urine test shows it correctly identifies bladder cancer in 69% to 87% of cases and correctly rules it out in about 75% to 76% of cases. This indicates its effectiveness in detecting the return of bladder cancer.
Both tests are non-invasive, avoiding surgery or instruments entering the body. This generally makes them easier to tolerate and results in fewer side effects compared to procedures like cystoscopy. Studies have not reported any major safety concerns with these tests.12345Why are researchers excited about this trial?
Researchers are excited about these methods because they offer a less invasive approach to monitoring bladder cancer. While the standard of care typically involves frequent cystoscopies, which can be uncomfortable and invasive, the Bladder EpiCheck and Xpert Bladder Cancer Monitor tests provide a non-invasive alternative through urine testing. These urine tests are designed to be used at intervals of 6 and 18 months, potentially reducing the need for as many cystoscopies to once every 12 and 24 months. This could improve patient comfort and compliance with bladder cancer surveillance while still effectively monitoring for cancer recurrence.
What evidence suggests that this trial's urine tests could be effective for bladder cancer surveillance?
This trial will compare the effectiveness of different surveillance methods for bladder cancer. Participants in the EpiCheck arm will undergo urine testing with the Bladder EpiCheck urine test at 6 and 18 months, and cystoscopy at 12 and 24 months. Research has shown that the Bladder EpiCheck urine test effectively detects bladder cancer recurrences, with a high accuracy rate of 99% for ruling out high-grade cancer when the test result is negative. Additionally, studies indicate it correctly identifies cancer 90% of the time and accurately rules out cancer 83% of the time in patients being monitored, making it a strong tool for ongoing checks.
Participants in the Xpert arm will use the Xpert Bladder Cancer Monitor urine test at 6 and 18 months, with cystoscopy at 12 and 24 months. The Xpert Bladder Cancer Monitor also shows promise, detecting cancer recurrences with an accuracy of 83-87% and ruling out cancer 75-76% of the time. This test is especially effective at finding high-grade cancer, making it useful for regular follow-up checks. Both tests are non-invasive and provide reliable results.36789Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for adults over 18 who can consent in English or Spanish, have a history of low-grade intermediate-risk non-muscle invasive bladder cancer, and are willing to follow the study's procedures. Pregnant women, those with total bladder removal or urinary diversions, muscle-invasive tumors, upper tract disease unless surgically treated and recurrence-free, or anatomic issues preventing cystoscopy cannot join.Inclusion Criteria
