Confocal laser endomicroscopy for upper tract urothelial carcinoma: validation of the proposed criteria and proposal of a scoring system for real-time tumor grading
To validate proposed confocal laser endomicroscopy (CLE) criteria for upper tract urothelial carcinoma (UTUC) and propose a scoring system for real-time tumor grading, emphasizing its significance in clinical practice.
Key Findings:
The prevalence of proposed CLE criteria for UTUC was assessed, revealing specific diagnostic accuracy metrics.
Diagnostic accuracy of CLE for UTUC grading was evaluated, showing significant results.
A scoring system for CLE-based grading of UTUC was proposed, aimed at enhancing clinical applicability.
Interpretation:
CLE shows potential for real-time grading of UTUC, but further validation is necessary due to the differences in imaging characteristics compared to bladder cancer, which may impact clinical outcomes.
Limitations:
The study excluded flat lesions from analysis.
The non-diagnostic yield of CLE recordings may affect overall diagnostic accuracy.
The smaller CLE probe may influence visual appearance and criteria applicability, and potential biases in rater assessments should be considered.
Conclusion:
CLE may enhance intraoperative risk stratification for UTUC, but validation of criteria and scoring systems is essential for clinical implementation to ensure reliability.
