Could skipping chemo speed up bladder cancer surgery without harm?
NCT ID NCT05776758
First seen Aug 17, 2026 · Last updated Aug 18, 2026 · Updated 1 time
Summary
This phase 3 trial asks whether removing the bladder right away is as effective as giving chemotherapy first, for patients with muscle-invasive bladder cancer who have no visible tumor left after a thorough biopsy. About 236 adults will be randomly assigned to either surgery alone or chemo plus surgery. The goal is to see if skipping chemo avoids unnecessary side effects and delays without reducing survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cisplatin-based neoadjuvant chemotherapy
- What this could lead to
- If skipping chemo proves as effective, patients could avoid unnecessary side effects and get surgery sooner.
- What could go wrong
- The trial is still recruiting and results are not yet available. Skipping chemo might slightly increase the risk of cancer returning, and the study only applies to a specific patient group.
