In a recent head-to-head comparative study in patients with recurrent prostate cancer [20], while 18F-Fluciclovine and [68 Ga]Ga-PSMA-11 PET imaging had similar detection rates (79.3%, 18F-fluciclovine; 82.8%, [68 Ga]Ga-PSMA-11; p = 0.64), 18F-fluciclovine was more efficient in detecting local recurrence in 37.9% of examined cases (compared to 27.6% for [68 Ga]Ga-PSMA-11, p = 0.03). Here, FOLH1 is linked to prostate carcinoma.
