Interim Analysis

The diagnostic tools for detecting patients with early prostate cancer are limited due to poor diagnostic performance. The positron emission tomography (PET) combination with the diagnostic radiopharmacy is a non-invasive tool to provide the molecular imaging of the whole body and offer more comprehensive physiological information and then can raise the diagnostic performance. Prostate-specific membrane antigen (PSMA)-targeting pharmaceuticals have been regarded as the most promising diagnostic tool to diagnose patients with prostate cancer. Currently, the 18F-PSMA-1007 as PSMA-targeting 18F-radiolabeled pharmaceuticals have developed and successfully used in patients with intermittent- and high-risk prostate cancer or recurrent prostate cancer. The study aims to understand the diagnostic performance of 18F-PSMA-1007 PET/CT in different-stage prostate cancer patients by initiating the first multicenter clinical trial of 18F-PSMA-1007 in Taiwan.
