Effect of Neoadjuvant Chemotherapy on MRI Accuracy Before Cystectomy

Standard neoadjuvant chemotherapy for muscle-invasive bladder cancer, typically consisting of cisplatin-based regimens such as MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin) or gemcitabine and cisplatin. Administered prior to radical cystectomy to shrink the tumor and improve surgical outcomes. The post-treatment MRI findings will be analyzed for correlation with histopathological results after surgery.

Surgical removal of the urinary bladder, typically performed in patients with muscle-invasive bladder cancer. In this study, participants in both arms will undergo radical cystectomy, either directly or following neoadjuvant chemotherapy. Histopathological examination of surgical specimens will be compared with MRI findings for staging accuracy assessment.
