Purpose.
To determine the clinical significance of unexpected, abnormal FDG uptake in the prostate in patients undergoing FDG-PET/CT for staging of other primary malignancies without a prior history of prostate carcinoma.
Methods.
Retrospective search of FDG-PET/CT studies to identify patients with unexpected, abnormal FDG uptake in the prostate gland, who underwent subsequent biopsy, was performed.
26 patients were identified.
Images were reviewed to determine the pattern of uptake within the prostate (focal or diffuse) and maximum standardized uptake value (SUVmax).
PSA and Gleason scores were recorded.
Results.
15/26 (58%) patients were found to have prostate carcinoma.
Gleason scores ranged from 6 to 9.9.
There was no statistical difference in the pattern of uptake (focal versus diffuse) or the SUVmax.
Serum PSA levels with cancer (range, 2–26.8 ng; mean, 10.2 ng) and those without cancer (range, 2–10.5 ng; mean, 2.2 ng) were statistically significant (P<0.007, Wilcoxon rank sum test).
Conclusions.
Patients with abnormal uptake in the prostate have a 58% likelihood of occult prostate cancer.
In the setting of elevated serum PSA levels, abnormal prostate uptake should therefore be viewed with suspicion and a urology consult should be obtained; however, it is irrelevant in patients with underlying aggressive malignancies.
