Sensitivity of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy |
Sensitivity is defined as the ratio of the proportion of the patients who have the condition of interest and whose test results are positive over the number who have the disease. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true-negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Follow-up scans for up to one year can be used in analysis |

Specificity of of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy |
Specificity is defined as the number of non-diseased participants correctly classified divided by all non-diseased individuals. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true-negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Follow-up scans for up to one year can be used in analysis |

Positive Predictive Value (PPV) of of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy |
PPV is the proportion of patients with positive test who actually have the disease. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true-negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives.

Negative Predictive Value (NPV) of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy |
NPV is the ratio of participants truly diagnosed as negative to all those who had negative test results. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true- negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Follow-up scans for obtained up to one year after study scan be used in analysis. |

Number of Participants With Grade 3 Treatment-related Adverse Events |
All grade 3 and above adverse events were recorded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.0. The Investigator assigns grade, attribution of the possible association of the event with use of the investigational drug. The safety parameters include spontaneous reports of adverse events reported to the investigator by patients |

Sensitivity of PSMA PET for the Detection of Extra-pelvic Nodal Metastases |
Gallium 68 labeled PSMA-11 (68Ga-PSMA-11) positive lymph nodes will be considered for detection of extra-pelvic nodal metastases and assessed by change in size. Participants who if on follow-up imaging within 3-12 months, have lymph nodes which decrease by more than 30% or increase by more than 20% in short axis diameter (with a minimum of 3 mm in change in size) or with solitary lymph node regions show a decrease of Prostate-specific antigen (PSA) by >50% after targeted treatment and the lymph nodes do not change in size (less than 30% decrease or less than 20% increase in short axis diameter) will be counted as true positives. If on follow-up imaging, sites of initial 68Ga-PSMA-11 positive lymph node lesions < 30% without systemic therapy or focal therapy at this site or if 68Ga-PSMA-11 positive lymph node lesions that do not meet criteria for above false positive or true positive will be counted as false positives. |
