What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores the best way to monitor veterans with high-grade non-muscle invasive bladder cancer. Participants will be randomly assigned to either low-intensity or high-intensity surveillance, involving different frequencies of cystoscopy (a procedure to look inside the bladder) and urine tests. The goal is to determine which approach more effectively detects cancer recurrence. Veterans who recently had a bladder tumor removed and show no signs of cancer in their first follow-up check may be suitable for this study. As an unphased trial, this study offers veterans the opportunity to contribute to research that could enhance future cancer monitoring strategies.

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop taking your current medications. Treatment for bladder cancer will be decided by your VA clinician, so it's best to discuss your medications with them.

What prior data suggests that these surveillance intervals are safe for bladder cancer patients?

Research has shown that low-intensity monitoring for bladder cancer is generally safe. In a study of 1,542 patients with high-risk non-muscle invasive bladder cancer (NMIBC), 520 patients followed a low-intensity monitoring plan. This approach did not increase the risk of dying from bladder cancer compared to more frequent monitoring. Patients on low-intensity plans also required fewer surgeries, with 37 surgeries per 100 person-years compared to 99 for those on high-intensity plans.

Overall, low-intensity monitoring appears well-tolerated and does not raise the risk of serious outcomes like death from bladder cancer. These findings suggest that this option is safe for those considering it.12345

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores different surveillance strategies for bladder cancer, potentially impacting patient care significantly. Current standard protocols involve frequent cystoscopies and urine tests, which can be invasive and inconvenient. The trial compares high-intensity surveillance, which aligns with current guidelines, to low-intensity surveillance, which reduces testing frequency over time. If low-intensity surveillance proves effective, it could lead to less invasive, more patient-friendly care without compromising outcomes. This could mean fewer hospital visits and a better quality of life for patients managing bladder cancer.

What evidence suggests that this trial's surveillance methods could be effective for bladder cancer?

This trial will compare high-intensity and low-intensity surveillance for bladder cancer. Research has shown that for high-grade non-muscle invasive bladder cancer, a low-intensity monitoring approach results in fewer surgeries, such as tumor removals. Specifically, patients underwent 37 surgeries per 100 person-years compared to 99 with more intensive methods. Studies indicate that this approach does not increase the risk of cancer progression or mortality. Many patients under low-intensity monitoring continue to do well over time, suggesting it can be a safe and effective way to monitor bladder cancer without frequent invasive procedures.12456

Are You a Good Fit for This Trial?

This trial is for veterans who've had high-grade non-muscle invasive bladder cancer and a recent TURBT procedure. They must have completed their first cystoscopy post-surgery without issues. The study excludes those with certain conditions or treatments that could interfere with the trial.

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Randomization and Initial Surveillance

Participants are randomized to either low- or high-intensity surveillance programs after a normal first cystoscopy post-TURBT

3 months
1 visit (in-person)

Participants undergo surveillance cystoscopy and urine cytology testing according to their assigned intensity program

24 months
Every 3 months (in-person)

Extended Surveillance

Surveillance continues with less frequent visits, every 6 months up to 48 months, then annually

What Are the Treatments Tested in This Trial?

Interventions

  • High Intensity Surveillance
  • Low Intensity Surveillance

Trial Overview

The study compares two monitoring approaches after bladder tumor surgery: 'Low Intensity Surveillance' versus 'High Intensity Surveillance'. Participants will be randomly assigned to one of these groups, and outcomes will be checked by blinded assessors to reduce bias.
