This pilot clinical trial studies how well TracelT hydrogel works in localizing bladder tumors in patients undergoing radiation therapy for bladder cancer. TracelT hydrogel marks the location of a bladder tumor and makes it more visible during imaging tests. Using TracelT hydrogel tissue marker may help doctors learn more about tumor location and altering radiation dosage for bladder cancer.
I. To utilize the TraceIT hydrogel tissue marker in localizing bladder tumors during
transurethral resection of bladder tumors (TURBT).
II. To improve identification of gross tumor or tumor bed location in patients receiving
chemoradiation treatment for bladder cancers.
I. To report adverse events surrounding the placement of the TraceIT tissue marker.
II. To calculate the actual dose received by the bladder tumor bed, as delineated by the
III. To compare the dosimetric impact to the tumor bed of daily patient alignment to the
pelvic bones, versus alignment to the whole bladder, versus alignment to the hydrogel
IV. To calculate the amount of normal tissue radiation dose decrease achievable without
losing tumor coverage, with better tumor targeting with hydrogel placement.
Patients undergo transurethral resection of bladder tumors and receive TracelT hydrogel via
injection. Patients undergo standard of care radiation therapy within 8 weeks of TracelT

Primary Outcome 1 - Measure: Changes in interfraction motion of the marker measured by cone beam computed tomography (CT) and x/y/z coordinates
Primary Outcome 1 - Time Frame: Baseline up to 8 weeks
Primary Outcome 2 - Measure: Changes in tumor bed size and shape as delineated by the hydrogel and measured by cone beam CT and x/y/z coordinates
Primary Outcome 2 - Time Frame: Baseline up to 8 weeks
- Histologically confirmed malignancy of the bladder
- No prior cystectomy
- Treatment plan for bladder must include at least 4 weeks of daily radiation treatment
(most patients will receive chemotherapy concurrent with radiation, but this is not
required for trial enrollment)
- Patient must undergo TraceIT hydrogel placement within 8 weeks prior to starting
radiation therapy for bladder cancer
- Participants must have a complete history and physical examination within 60 days of
- Participants must be able to provide informed consent for treatment and trial
- No restrictions on prior treatment to be eligible
- Prior cystectomy
- Unable to have TraceIT hydrogel placement < 8 weeks prior to beginning radiation
- Treatment for metastatic bladder cancer
