The Role of Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography in Primary Staging of Selected Renal Tumours: Initial Experience in a Multicentre Cohort.
Tariq et al., Eur Urol Focus 2024
DOI: 10.1016/j.euf.2023.12.004
New Insights:
- PSMA PET/CT detected more metastatic lesions in renal cancer than conventional imaging (195 vs 160).
- A significant proportion of renal cancers were PSMA-avid, with clear-cell renal cell carcinoma showing the highest avidity (98%).
- Staging with PSMA PET/CT led to a change in management for 32% of patients, with 20% experiencing major changes and 12% minor changes.
Importance:
This study suggests that PSMA PET/CT could be a valuable tool in the primary staging of renal cancer, potentially leading to more accurate detection of metastases and influencing treatment decisions.
Contribution to Literature:
The findings contribute to the growing evidence that PSMA PET/CT may offer superior diagnostic capabilities compared to traditional imaging methods, which could result in improved patient outcomes through better-informed management strategies.
Study Details:
The study was a retrospective cohort analysis of 61 PSMA PET/CT scans from patients with primary renal cancer or incidental renal lesions. The majority of the primary lesions were clear-cell renal cell carcinoma, which showed high PSMA avidity. The study was conducted in Brisbane, Australia, and spanned five years.
Limitations:
The study’s retrospective design, potential selection bias, lack of blinding in PSMA reporting, and the use of different PSMA radiotracers are noted as limitations.
