Participant Flow

Participants were recruited from Emory University Hospital and the Winship Cancer Institute in Atlanta, Georgia from November 2015 to April 2017. All study procedures were completed by March 31, 2018.

Participants with abnormal anti-1-amino-3-\[18F\]fluorocyclobutane-1- carboxylic acid (FACBC) positron emission tomography (PET)-CT scans were to have both targeted and template biopsies while those with normal FACBC PET-CT scans would have only the standard of care template biopsy. None of the study participants had a normal FACBC PET-CT scan.

PRIMARY outcome

Timeframe: Two weeks

Population: All 21 participants are included in the analysis, and all participants had both types of biopsies performed. The total number of core samples taken during biopsy are given as the overall number of participants analyzed and the percentage of these core samples that tested positive for prostate cancer are given as the outcome measure data.

The cancer detection rate per core was compared between the targeted prostate biopsy and standard of care prostate biopsy.

Outcome measures

Outcome measures
Measure
Targeted Biopsy
n=125 Prostate biopsy core samples
Fluciclovine defined targets were biopsied using the 3-D visualization and navigation platform to guide the biopsy needle and record its path.
Standard Biopsy
n=246 Prostate biopsy core samples
The standard transrectal ultrasound guided biopsy collects 2 cores per region (when possible) from 6 standard regions of the prostate.
Percentage of Cores Positive for Cancer
32.0 percentage of positive core samples
4.5 percentage of positive core samples
