Diagnostic Accuracy of 18F-FDG PET/CT in Muscle-invasive Bladder Cancer (MIBC-PET)

4. august 2026 opdateret af: University Hospital of Ferrara

Diagnostic Accuracy of 18F-FDG PET/CT in Muscle-invasive Bladder Cancer: Rationale and Design of the MIBC-PET Study

MIBC-PET is a prospective, monocentric, no-profit study with paired imaging comparison enrolling 60 patients with newly diagnosed, histologically confirmed high-grade MIBC. All patients undergo baseline staging with [18F]FDG PET/CT and contrast-enhanced CT (ceCT) of chest, abdomen, and pelvis. A second [18F]FDG PET/CT and CT are performed after two cycles of neoadjuvant therapy. [18F]FDG PET/CT includes both standard delayed imaging and an early dynamic pelvic acquisition to overcome urinary tracer interference. The primary endpoints are (1) diagnostic accuracy of [18F]FDG PET/CT versus ceCT for baseline staging, and (2) accuracy of [18F]FDG PET/CT in predicting pathological response to neoadjuvant chemotherapy. Secondary endpoints include validation of early dynamic [18F]FDG PET/CT for local staging and radiomic/AI-based predictive modeling.

Baseline Diagnostic Accuracy of [18F]FDG PET/CT in MIBC
Tidsramme: At baseline, prior to initiation of neoadjuvant therapy (each cycle has a duration of 21 days)
Assessment of [18F]FDG PET/CT for initial staging of newly diagnosed muscle-invasive bladder cancer, compared with thoraco-abdomino-pelvic contrast-enhanced CT (gold standard) to determine diagnostic accuracy in defining disease extent.
At baseline, prior to initiation of neoadjuvant therapy (each cycle has a duration of 21 days)
Interim [18F]FDG PET/CT Prediction of Pathological Response
Tidsramme: After 2 cycles of neoadjuvant therapy, prior to surgery (each cycle has a duration of 21 days)
Evaluation of the ability of interim [18F]FDG PET/CT to predict pathological response to neoadjuvant treatment, assessing its potential role in guiding therapeutic decision-making.
After 2 cycles of neoadjuvant therapy, prior to surgery (each cycle has a duration of 21 days)
