Clinical Trial Summary

Purpose：To evaluate whether immediate multiparametric MRI evaluate the sensitivity of modified neoadjuvant chemotherapy early in patient with muscle invasive bladder cancer（MIBC）. Rationale：Multiparametric MRI may help detect the early changes of bladder cancer receiving neoadjuvant chemotherapy.

Clinical Trial Description

Objective Primary: To evaluate whether multiparametric MRI can determine the sensitivity of modified neoadjuvant chemotherapy early in patient with muscle invasive bladder cancer（MIBC）. Secondary：To determine whether multiparametric MRI can predict the prognosis of modified neoadjuvant chemotherapy early in patient with muscle invasive bladder cancer. Patients may receive neoadjuvant chemotherapy (typically three 21-day courses of modified gemcitabine-cisplatin(GC) therapy) followed by radical cystectomy and lymph node dissection. Patients with primary bladder cancer or recurrence which is confirmed by pathology of previous biopsy or TURBT, undergo a multiparametric MRI(mpMRI) at baseline to stage the primary tumor. The mpMRI includes T2-weighted MRI, diffusion-weighted imaging, and dynamic contrast enhancement, which will be given a five-point VI-RADS（Vesical Imaging-Reporting And Data System） score by two radiologists specialized in urogenital radiology. Patients considered NMIBC（Non-muscle invasive bladder cancer） with mpMRI will be given TURBT, while patients with MIBC（Muscle invasive bladder cancer）will receive radical cystectomy and lymph node dissection after three 21-day courses of modified gemcitabine-cisplatin neoadjuvant chemotherapy. Patients also undergo an immediate mpMRI scan after one, two, and three cycles of neoadjuvant chemotherapy. Specimens from the radical cystectomy are then examined by the pathology department as standard routine. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
