Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Evaluate the impact of 18F-FDG-PET-CT on the staging of patients with muscle invasive bladder cancer. Based on the results of 2 18F-FDG-PET-CT's patients are stratified in non-metastatic, oligometastatic and polymetastatic bladder cancer patients and the treatment is adapted accordingly to improve overall survival.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Non-metastatic MIBC

No signs of extra-pelvic metastasis on conventional imaging (abdominopelvic and thoracic CT/MRI) and 18F-FDG-PET-CT's

Group Type ACTIVE_COMPARATOR

Standard of care

Intervention Type PROCEDURE

Patient receives standard of care therapy with either radical cystectomy with pelvic lymph node dissection or trimodality therapy (consisting of a visible complete TURb and radio chemotherapy). Afterwards regular follow up is performed.

Oligo-metastatic MIBC on 18F-FDG-PET-CT

No signs of extra-pelvic metastasis on conventional imaging (abdominopelvic and thoracic CT/MRI) but presence of ≤ 3 metastasis on 1 or both 18F FDG PET-CT 's

Group Type EXPERIMENTAL

Metastasis directed therapy (MDT)

Intervention Type RADIATION

Patient receives standard of care therapy with either radical cystectomy with pelvic lymph node dissection or trimodality therapy (consisting of a visible complete TURb and radio chemotherapy). Concurrently, the oligometastasis will be treated with stereotactic body radiotherapy or metastasectomy.

Poly-metastatic MIBC on 18F-FDG-PET-CT

No signs of extra-pelvic metastasis on conventional imaging (abdominopelvic and thoracic CT/MRI) but presence of \> 3 metastasis on 1 or both 18F FDG PET-CT 's

Group Type EXPERIMENTAL

Immunotherapy

Intervention Type DRUG

Patient receives standard of care therapy with either radical cystectomy with pelvic lymph node dissection or trimodality therapy (consisting of a visible complete TURb and radio chemotherapy). Afterwards immunotherapy will be initiated and regular follow up will be performed.
