Giving 99mTc-PSMA-I\\&S may detect PSMA-expressing lymph nodes during surgery using a gamma probe and may help guide doctors to detect prostate cancer that has spread to the lymph nodes.', 'detailedDescription': 'PRIMARY OBJECTIVE:\n\nI. To define the biodistribution of 99mTc-based PSMA imaging and surgery agent (99mTc-PSMA-I\\&S) in normal and malignant tissues of patients with prostate cancer (PCa) with histopathology validation, when available.\n\nSECONDARY OBJECTIVES:\n\nI. To correlate the 99mTc-PSMA-I\\&S accumulation within tumor lesions observed by in-vivo single-photon emission computed tomography (SPECT), ex-vivo gamma measurements and level of prostate-specific membrane antigen (PSMA) expression quantified by histopathology, when available.\n\nII. To define the best time-point for radio-guided surgery (RGS) with the highest tumor-to-background ratio following 99mTc-PSMA-I\\&S administration.\n\nOUTLINE:\n\nThe first 5 patients receive an initial dose of 99mTc-PSMA-I\\&S intravenously (IV) followed by 5 SPECT/CT scans at 3-5, 5-20, 17-21, 25-29, and 40-46 hours later. These 5 patients then receive a second dose of 99mTc-PSMA-I\\&S IV and then undergo standard of care surgery.
