FOLH1 and prostate cancer: PSMA is a transmembrane protein that is highly expressed on the surface of prostate cancer cells, representing an optimal target both for imaging and therapy.9PSMA-targeted radiotracers, labeled with radioactive isotopes, as gallium-68 [68Ga], selectively bind to PSMA receptors, enabling the visualization of prostate cancer lesions.10Fusion of PET and CT images offers superior sensitivity and specificity in detecting prostate cancer lesions, particularly in cases of biochemical recurrence and metastatic disease.11
