PSMA PET scanning can improve decision making for prostate cancer treatment

Detailed PSMA PET mapping of cancer recurrence in the prostate bed shows that current radiotherapy contouring guidelines—which determine the target areas for treatment—miss a significant number of lesions and may irradiate healthy tissues unnecessarily. In a new study published online by the Journal of Nuclear Medicine, researchers are calling for the redefinition of prostate bed contouring guidelines to improve outcomes for patients.
