Within 28 days of imaging, radical prostatectomy with pelvic lymph node dissection will occur.

What was measured

Positive Predictive Value (PPV) is based on a 18F-DCFPyL PET/CT image result and a histopathology result. The PPV is determined from the number of true positives (positive 18F-DCFPyL image and a positive histopathology result for prostate cancer) divided by the number of participants with a positive 18F-DCFPyL image.

Analysis population: The Evaluable Set of high risk prostate cancer participants (Cohort A) includes those who received 18F-DCFPyL, had a prostatectomy or lymphadenectomy, and provided a 18F-DCFPyL PET/CT image result and a corresponding histopathology result.

Groups in this outcome

High Risk Prostate Cancer (Cohort A)

High risk prostate cancer participants planned for radical prostatectomy with pelvic lymph node dissection were enrolled to receive a single dose of 9 mCi (333 MBq) IV injection of 18F-DCFPyL, followed by PET/CT imaging acquired 1-2 hours post-PyL injection.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
