Bladder Fiducial Markers and Multiparametric-MRI (Mp-MRI) to Optimize Bladder Chemo-radiotherapy
About
Brief Summary
The purpose of this study is to examine the usefulness of implanting small 24-K gold fiducial markers around a bladder tumor site, so that a Radiation Oncologist can identify the original tumor location at the time of radiation treatment. Other goals of the study include assessing whether a new MRI imaging technology can help with detection of bladder cancer earlier and more accurately when evidence of bladder cancer is not visible by scope.

Inclusion Criteria:
- Pathologically (histologically or cytologically) proven diagnosis of primary urothelial carcinoma of the bladder. Subjects with mixed histology are required to have a dominant traditional cell carcinoma (TCC) pattern.
- Clinical stage T2-T4a, Nx, M0 considered appropriate for, and electing to receive, chemoradiation of the bladder
- Planned TURBT as part of the normal course treatment, to take place prior to the initiation of chemo irradiation
- Adequate renal function: Serum creatinine < 2 mg/dL OR calculated creatinine clearance (CrCl) > 30ml/min
- Ability to understand and willingness to sign a written informed consent
- Women of child-bearing potential and men must agree to use adequate contraception prior to study entry, during study participation, and for 90 days after study treatment discontinuation
- Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
Exclusion Criteria:
- Subjects with primary TCC of the ureter, urethra, or renal pelvis, without TCC of the bladder, are not allowed
- Known distant metastatic disease (e.g. pulmonary or hepatic metastases)
- Subjects with malignant lymphadenopathy in the abdomen or pelvis considered appropriate for radical cystectomy and lymphadenectomy with the goal of complete resection of all malignant disease are allowed
- Patients with bladder abnormalities that preclude safe placement of fiducial markers (i.e. abundant large diverticuli or cellules, active or recurrent urinary infection)
- Planned (or prior history of) definitive bladder irradiation
- Intravesical chemo- or biologic therapy within 6 weeks of first treatment
- Any planned neoadjuvant systemic immunotherapy. Note that prior bacille Calmette-Guerin vaccine (BCG) is not an exclusion
- Clinically significant active infection or uncontrolled medical condition that would preclude participation in study
- Pregnant or nursing women are excluded
- Previous malignancy other than TCC that, in the opinion of the treating investigator, is likely to interfere with protocol treatment
- Individuals with severe renal failure and cannot receive MRI contrast
