Study Summary

This phase II trial studies how well 68Ga-PSMA-11 positron emission tomography (PET)/computed tomography (CT) works in detecting the spread of cancer to the bones (bone metastasis) in patients with prostate cancer and increased PSA after treatment (biochemical recurrence) during androgen deprivation therapy. Diagnostic procedures, such as 68Ga-PSMA-11 PET/CT, may help find and diagnose prostate cancer and find out how far the disease has spread.

Primary Outcome

68Ga-PSMA-11 PET will be compared to bone scan/CT for M1b disease in prostate cancer patients progressing during androgen deprivation therapy. Patients who have at least one positive bone lesion will be rated positive. Patients will be treated as binary categorization. The analysis of the primary objective will utilize the McNemar's test to compare the detection rate between the imaging techniques.

Interventions
