Objective:

To summarize existing evidence on the predictive value of MRI in assessing extracapsular extension (ECE), seminal vesicle involvement (SVI), and lymph node involvement (LNI) in radio-recurrent prostate cancer patients who are candidates for salvage prostatectomy, highlighting its significance in improving patient outcomes.

Key Findings:

• Four studies with 94 patients were included, indicating a significant need for further research.
• Prevalence of ECE ranged from 50% to 87.5%, suggesting variability in MRI effectiveness.
• Prevalence of SVI ranged from 33.3% to 68.42%, highlighting the importance of accurate staging.
• Nodal involvement reported in 26.32% and 17.78% of patients, emphasizing the need for improved diagnostic tools.

Interpretation:

MRI demonstrates variable predictive value for ECE, SVI, and LNI in patients with radio-recurrent prostate cancer, but the evidence is limited and requires further validation to enhance clinical decision-making.

Limitations:

• Limited number of studies (only four) included in the analysis, which may affect the generalizability of the findings.
• All studies were single-center and retrospective, potentially introducing bias.
• Variability in MRI protocols and radiologist experience may impact the reliability of results.

Conclusion:

MRI is a potentially useful tool for local staging in radio-recurrent prostate cancer, but further studies are needed to confirm its reliability and improve diagnostic accuracy, which could significantly impact patient management.
