Clinical Trial Summary

The purpose of this study is to see whether 68Gallium PSMA-PET/CT scans are an effective way to detect sites of cancer in people with metastatic bladder cancer. The study researchers want to learn if a 68Gallium PSMA PET/CT scan will work better, the same, or not as well as the PET/CT scans doctors usually use for imaging bladder cancer (FDG-PET/CT scan).

Eligibility

Inclusion Criteria:

• Patients with histologically confirmed metastatic urothelial carcinoma with extrapelvic nodal and/or visceral sites of disease (including lung, liver, bone, or soft tissue)

• At least 3 lesions assessable by FDG PET/CT according to RECIST and PERCIST guidelines where applicable, that are determined suspicious for metastasis by an MSKCC attending radiologist or nuclear medicine physician.

• Patients on a therapeutic clinical trial

• Patients undergoing active surveillance with a known history of non-urothelial malignancies

• Women who are pregnant. All women of childbearing potential must have a documented negative pregnancy test.

Primary	Define the proportion of patients with 1 or more lesions detectable by 68Gallium PSMA-PET/CT	If 6 of 10 patients have at least one lesion identified both on standard of care FDG PET/CT and also detected on 68Gallium PSMA-PET/CT, this imaging modality will be worthy of further exploration in metastatic UC.	1 year
