Condition: Bladder Cancer · NMIBC · Sponsor: The First Affiliated Hospital with Nanjing Medical University
Bladder cancer is a common malignancy in the urinary system, ranking 11th in cancer incidence in China (3.48/100,000), with male incidence ranking 8th (5.70/100,000). It is classified as non-muscle-invasive bladder cancer (NMIBC) or muscle-invasive bladder cancer (MIBC) based on muscle involvement. About 75% of patients are initially diagnosed with NMIBC, with Ta, T1, and Tis stages comprising 70%, 20%, and 10%, respectively. With the advancement of magnetic resonance imaging (MRI), its role in bladder cancer diagnosis and staging has expanded. Multiparametric MRI (MpMRI) enhances staging accuracy with better anatomical visualization. In 2018, Valeria et al. introduced the VI-RADS scoring system, which uses MpMRI to predict tumor stage. Retrospective studies by Wang et al. found that all tumors with a VI-RADS score of 1 were NMIBC, and 95.1% of tumors with a score of 2 were also NMIBC. A VI-RADS score of ≤2 can be used to identify NMIBC with high sensitivity. NMIBC shows varied risks for recurrence and progression based on tumor characteristics like size, stage, grade, and multiplicity. The European Association of Urology (EAU) risk stratification system, established in 2021, classifies NMIBC into low-, intermediate-, high-, and very-high-risk groups. Transurethral resection of bladder tumor (TURBT) is the primary diagnostic and therapeutic approach for most NMIBC cases. However, residual tumors can remain after the first TURBT. For Ta and T1 tumors, 17%-72% and 33%-78% of …
