FOLH1 and neoplasm: Although patient 5 showed no mismatch findings, PSMA expression in the tumour lesions was low, predominantly < healthy liver, and tumour uptake of the three radioligands was balanced (mean deviation from the SUVmean of [68Ga]Ga-PSMA-11 PET: [68Ga]Ga-FAPI-46: + 2.2%, 2-[18F]FDG: -28.9%), making him an unsuitable candidate for [177Lu]Lu-PSMA-617 RLT.
