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 locati...

Detailed Description

This study of fiducial markers in patients with localized muscle-invasive bladder cancer will enroll patients electing bladder preservation with tri-modal therapy. 24-K gold fiducial markers will be ...

Eligibility Criteria

Inclusion

  • 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

  • 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
