NCT ID NCT07285408
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This observational study will follow 150 adults with early-stage bladder cancer to see if factors like muscle loss, fat distribution, and nutrition affect the chance of cancer coming back or getting worse. Participants will have standard treatments and extra assessments including CT scans and questionnaires. The goal is to find better ways to predict individual risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors better predict which patients are at higher risk of bladder cancer returning or worsening, leading to more personalized follow-up care.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly improve outcomes. Results may show associations but not prove cause and effect.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Adult patients diagnosed with non-muscle-invasive bladder cancer (NMIBC) undergoing transurethral resection of bladder tumor (TURBT) and guideline-based surveillance at a tertiary urology center. The study population includes individuals with and without body composition and nutritional abnormalities (sarcopenia, myosteatosis, obesity, or malnutrition) who meet eligibility criteria and consent to participate.

Inclusion Criteria: * Adults aged 18 years or older * Histologically confirmed non-muscle-invasive bladder cancer (NMIBC) (Ta, T1, or CIS) * Scheduled for transurethral resection of bladder tumor (TURBT) as part of standard care * Able to undergo CT imaging required for assessment of skeletal muscle index (SMI) and skeletal muscle density (SMD) * Completed preoperative clinical evaluation including: SARC-F, NRS, anthropometric measurements (BMI, waist circumference), serum albumin, and routine laboratory tests * Able and willing to provide written informed consent Exclusion Criteria: * Low-risk NMIBC, as defined by clinical guidelines * Muscle-invasive bladder cancer (≥ T2) at diagnosis * Expected survival less than 3 months * Contraindications to CT imaging (e.g., severe renal dysfunction, contrast allergy if contrast required) * Age under 18 years * Inability or unwillingness to adhere to scheduled follow-up * Any condition that, in the investigator's judgment, would interfere with participation or data integrity
