PSMA-targeted tracers with a photosensitizer are designed to accumulate in PCa lesions and the fluorescence camera or light (normal or laparoscopic 680 nm laser) can be focused to the tumor site as well, meaning that PSMA-targeted intraoperative imaging and tPDT is highly precise 11, 39, 40. The gene discussed is FOLH1; the disease is posterior cortical atrophy.
