Introduction:
The role of positron emission tomography (PET) prostate-specific membrane antigen (PSMA) in guiding radiation therapy treatment plans remains to be defined.Methods:
We conducted a retrospective observational study of patients with prostate cancer referred for radiotherapy. Our objective was to establish the role of PET-PSMA in decision-making and changes in the radiotherapy treatment plan.Results:
In the entire cohort, 26.8% had lymph node involvement outside the conventional field. The PET results upstaged and changed radiotherapy treatment plans for 75% in primary radiotherapy and 50% in salvage radiation.Conclusions:
PET-PSMA changes decision-making and treatment planning for radiotherapy, including treatment volumes not traditionally delimited in contour atlases.
