In men, prostate cancer (PCa) is the most frequently occurring cancer in Belgium. Recurrent disease after radical prostatectomy or local therapy with curative intent occurs in 30-40% of patients within 10 years. Biomarkers such as Prostate Specific Antigen are used for follow up of disease status in patients with prostate cancer. However, for salvage therapy to be successful, precise localization of metastases is necessary to determine the most appropriate treatment and to postpone expensive systemic therapies with their inherent toxicity. Recently, prostate specific membrane antigen (PSMA) has gained interest for PCa-specific imaging. Due to overexpression of PSMA in both primary and metastatic PCa, radiotracers targeting this protein have shown an increased selectivity and sensitivity compared to conventional imaging.
Our research team developed a new PET radiotracer, [18F]PSMA-11, for imaging PSMA in prostate cancer patients. During a phase 1 and 2 clinical trial, the safety of administration and the patient dosimetry has been evaluated, and the scan protocol has been optimized. Subsequently, a phase 3 trial has been set up to determine the position of [18F]PSMA-11 PET/CT within the field of available radiotracers for diagnosis of prostate cancer.
