Local radiotherapy for bladder cancer in patients not eligible for curative treatment

Official title: Local Radiotherapy for Urinary Bladder Cancer in Patients Not Eligible for Curative Treatment; a Prospective Randomized Phase III Trial.

Run by Umeå University · NCT07524426 · Data updated 2026-11-12

This trial tests whether adding local hypofractionated adaptive radiotherapy to standard care can improve survival and reduce symptoms for bladder cancer patients who aren’t candidates for curative treatment.

Is this trial a fit for you?

Likely a good fit

Adults with histologically confirmed muscle-invasive bladder cancer who are not deemed to benefit from curative treatment and are considered suitable for local radiotherapy.

Probably not a fit

Patients with extensive metastases, poor performance status, or plans for systemic therapy at inclusion may derive limited or no benefit.

What this trial studies

The study compares local, adaptive hypofractionated radiotherapy plus standard care versus standard care alone in adults with muscle-invasive bladder cancer who are not suitable for curative therapy. It uses modern radiotherapy techniques, including image guidance and treatment adaptation, to deliver effective but tolerable treatment. The trial is complemented by exploratory biomarker studies to identify potential predictors of prognosis and treatment response. The focus is on quality of life and survival in a population with high symptom burden and limited treatment options. Approximately 700 new bladder cancer patients are diagnosed annually in Sweden, and many older patients experience substantial comorbidity, underscoring the need for palliative, patient-centered approaches.

Why it matters

Potential benefit: If successful, patients could experience improved symptom control and longer survival with a tolerable, shorter, and more convenient radiotherapy approach.

How similar studies have gone: Previous studies in bladder cancer show mixed but encouraging signals for radiotherapy-based palliation improving symptoms and survival in selected patients.
