Local staging with multiparametric MRI in daily clinical practice: diagnostic accuracy and evaluation of a radiologic learning curve
To estimate the diagnostic accuracy of multiparametric MRI (mpMRI) for detecting locally advanced prostate cancer stages (pT3–4) prior to radical prostatectomy and to assess the existence of a radiologic learning curve, emphasizing its significance in clinical practice.
Key Findings:
The sensitivity of mpMRI for detecting overall T3 disease was 61%, indicating a need for improved training.
Inter-observer variability was significant, potentially due to varying experience levels among radiologists, which could affect diagnostic outcomes.
The use of standardized reporting (PI-RADS) improved classification over time.
Interpretation:
While mpMRI shows promise in detecting locally advanced prostate cancer, its diagnostic accuracy is still limited, and inter-observer variability highlights the critical need for improved training and standardization in clinical practice.
Limitations:
The study was retrospective and conducted in a single country, which may limit the generalizability of the findings.
No centralized review of mpMRI analyses was performed.
The radiologists were not blinded to clinical information, which may introduce bias.
Conclusion:
mpMRI can aid in the staging of locally advanced prostate cancer, but its accuracy varies and is influenced by the radiologist's experience, indicating a need for ongoing training and standardization in clinical practice to enhance decision-making.
