Trial Outcomes & Findings for Role of FDG-PET CT in the Management of Muscle Invasive Bladder Cancer (NCT NCT04053101)

NCT ID: NCT04053101

Last Updated: 2025-09-18

Results Overview

Performance sensitivity of FDG-PET CT for LN staging on diagnosis of MIBC (before and after NAC and before cystectomy and LN dissection). Gold standard : pathological results (complete response vs no complete response). Comparison of PET-CT TNM staging between patients with and patients without a Pathological Complete Response. Sensitivity rate : count of participants with complete response as per FDG-PET divided by count of participants with pathoplogical complete response

PRIMARY outcome

Timeframe: 16 weeks after inclusion

Population: Patients with complete pathological response

Performance sensitivity of FDG-PET CT for LN staging on diagnosis of MIBC (before and after NAC and before cystectomy and LN dissection). Gold standard : pathological results (complete response vs no complete response). Comparison of PET-CT TNM staging between patients with and patients without a Pathological Complete Response. Sensitivity rate : count of participants with complete response as per FDG-PET divided by count of participants with pathoplogical complete response

PRIMARY outcome

Timeframe: Date of pathological results, up to 20 weeks after inclusion

Population: Participants with NO pathoplogical complete response

Performance specificity of FDG-PET CT for LN staging on diagnosis of MIBC (before and after NAC and before cystectomy and LN dissection). Gold standard : pathological results (complete response vs no complete response). Comparison of PET-CT TNM staging between patients with and patients without a Pathological Complete Response Specificiity rate : count of participants with NO complete response as per FDG-PET divided by count of participants with NO pathoplogical complete response
