The Role of PSMA PET Imaging in Prostate Cancer Theranostics: A Nationwide Survey.

Prostate-specific membrane antigen (PSMA)-based imaging and theranostics have played an important role in the diagnosis, staging, and treatment of prostate cancer (PCa). We aimed to evaluate the acceptance and use of PSMA theranostics among German urologists. An anonymous online questionnaire was sent via survio.com to the members of the German Society of Urology (DGU). Seventy-two percent of participants performed PSMA positron emission tomography (PET) imaging regularly in biochemically recurrent PCa. Overall, 61% of participants considered PSMA-radioligand therapy to be very useful or extremely useful. PSMA PET imaging in high-risk PCa is more often considered by urologists working in a university setting than in nonuniversity settings or medical practices (51% vs. 25%, p < 0.001). Most perform PSMA-radioligand therapy as an option after all approved systemic treatments for metastatic castration-resistant PCa (56%) or after cabazitaxel (14%). A total of 93.9% and 70.3% of respondents consider the lack of reimbursement by health insurance to be the main obstacle to using PSMA PET imaging or radioligand therapy, respectively. PSMA-based imaging/theranostics are already widely applied but would find even more widespread use if reimbursement is clearly regulated by health insurance in Germany.
