Prostate-specific membrane antigen positron emission tomography (PSMA PET) scans help precisely locate prostate cancer. This imaging guides radiotherapy for newly diagnosed, recurrent, or oligometastatic prostate cancer, improving treatment accuracy.
Area of Science:
- Oncology
- Radiotherapy
- Nuclear Medicine
Background:
- Radiotherapy is a curative option for localized prostate cancer and biochemical recurrence.
- Durable responses are achievable with radiotherapy for oligometastatic disease.
- Accurate staging and localization are critical for successful radiotherapy outcomes.
Purpose of the Study:
- To review the role of positron emission tomography in assessing prostate-specific membrane antigen distribution.
- To evaluate how PSMA PET imaging guides radiotherapy in various prostate cancer settings.
Main Methods:
- Review of recent data on PSMA PET imaging.
- Assessment of PSMA PET/CT for disease localization in prostate cancer.
Main Results:
- PSMA PET is increasingly used to assess disease extent and localization.
- This imaging modality aids in treatment planning for radiotherapy.
Conclusions:
- PSMA PET imaging is valuable for guiding radiotherapy in newly diagnosed, recurrent, and oligometastatic prostate cancer.
- Accurate disease assessment with PSMA PET enhances radiotherapy precision and potential efficacy.
