MRI Before and During Surgery in Diagnosing Patients With Bladder Cancer

Status: complete

The purpose of the research study is to see if stronger magnetic resonance imaging (MRI) machines can provide more information about bladder cancer before and during surgery.

Inclusion Criteria

Patient with known bladder cancer
Patient is scheduled for radical cystectomy and lymph node dissection
Patient is able and willing to give valid written informed consent
Patient has no contraindications to the MRI

Exclusion Criteria

Women who are pregnant or planning to become pregnant during the trial
Women who are breastfeeding
Patient with allergy to contrast agent
Patient with significant renal insufficiency, i.e. an estimated glomerular filtration rate (eGRF) less than 30 mL/min/1.73m^2
Any condition conflict based on the investigation’s clinical judgment that would prevent the patient from completion all trial assessments and visits
Inability or unwillingness to cooperate with requirements of this trial
Patients who exhibit noticeable anxiety and/or claustrophobia or who exhibit severe vertigo when they are moved into the MR
Patients with sickle cell anemia and other hemolytic anemia

PRIMARY OBJECTIVES:

I. To evaluate whether 3 Tesla MRI can accurately determine the primary tumor (T) stage and pelvic lymph nodes (N) stage for localized bladder cancer. The ability of 3 Tesla MRI to accurately assign stage will be compared to histopathology staging.

SECONDARY OBJECTIVES:

I. To determine whether 3 Tesla MRI can determine if the primary bladder tumor is responding to neoadjuvant chemotherapy at the mid-point of the planned treatment (after 2 cycles).

II. To assess whether an ultra-high-field MRI (> 3 Tesla) tissue scan can more accurately determine clinical stage of a primary bladder tumor and regional lymph nodes.

OUTLINE:

All patients undergo 3-Tesla MRI scans 2-4 weeks before surgery. Patients receiving neoadjuvant chemotherapy also undergo 3-Tesla MRI scans before the start of chemotherapy and after 2 courses of chemotherapy. Specimens collected during surgery are then assessed via ultra-high-field MRI.
