Effect of Neoadjuvant Chemotherapy on MRI Accuracy Before Cystectomy

NCT07202819 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 76

No results posted yet for this study

Summary

The goal of this clinical trial is to learn if neoadjuvant chemotherapy (NAC) affects the accuracy of magnetic resonance imaging (MRI) in staging muscle-invasive bladder cancer (MIBC). This study will also assess how tissue changes induced by NAC impact MRI interpretation. The main questions it aims to answer are:

Does NAC compromise the accuracy of MRI in staging MIBC?

Does NAC-induced tissue change affect the reliability of MRI in tumor assessment?

Researchers will compare MRI staging accuracy in MIBC patients who received NAC to those who went directly to surgery, to see if NAC impacts MRI's diagnostic performance.

Participants will:

Undergo MRI scanning before surgery

Receive either NAC or go directly to surgery, depending on their group assignment

Have their MRI results compared to histopathological outcomes after surgery

Conditions

Interventions

DRUG

Neoadjuvant Chemotherapy

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.

PROCEDURE

Radical Cystectomy

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.
