Multiprobe fluorescence in situ hybridization (FISH) is the gold standard for urinary cytology atypia. The Paris System guides FISH use, integrating morphology and molecular diagnostics for future advancements like next-generation sequencing.
Area of Science:
- Uropathology
- Cytogenetics
- Molecular Diagnostics
Background:
- Multiprobe fluorescence in situ hybridization (FISH) is crucial for diagnosing inconclusive urinary cytology.
- The Paris System (TPS) provides a framework for utilizing FISH and integrating morphological findings.
Purpose of the Study:
- To highlight the role of FISH in urinary cytology.
- To discuss the integration of FISH with morphological analysis.
- To explore the future potential of next-generation sequencing (NGS) in urinary diagnostics.
Main Methods:
- Review of current diagnostic standards in urinary cytology.
- Application of The Paris System guidelines for FISH testing.
- Discussion of emerging molecular technologies.
Main Results:
- FISH remains the established method for resolving ambiguous urinary cytology cases.
- Morphological correlation is essential for an accurate diagnostic approach.
- Next-generation sequencing shows promise for detecting multiple genetic alterations in urine specimens.
Conclusions:
- FISH is indispensable in current urinary cytology practice for inconclusive atypia.
- An integrative diagnostic approach combining morphology and FISH is emphasized.
- Next-generation sequencing is poised to become a significant diagnostic tool in the near future.
