View abstract on PubMed
Summary
This summary is machine-generated.T1 bladder cancer substaging improves outcome prediction. Micrometric methods are more reproducible than histometric techniques, suggesting standardization could enhance bladder cancer treatment.
Area Of Science
- Uro-oncology
- Cancer Staging
- Pathology
Background
- T1 bladder tumors exhibit heterogeneous behavior and prognosis, necessitating refined staging.
- Various substaging methods have been proposed to better stratify risk and guide treatment.
- Investigating the diagnostic and prognostic value of T1 substaging is crucial for improving oncologic outcomes.
Approach
- A systematic review of 63 studies (1990-2024) involving 8328 patients was conducted.
- Literature search included MEDLINE, EMBASE, and Cochrane Library databases following PRISMA guidelines.
- Studies focused on histometric and micrometric substaging techniques for T1 urothelial bladder cancer.
Key Points
- T1 substaging is a significant predictor of oncologic outcomes in bladder cancer.
- Micrometric substaging techniques demonstrate greater reproducibility and prognostic value compared to histometric methods.
- A lack of standardized, validated substaging systems hinders clinical application.
Conclusions
- Substaging T1 bladder tumors offers valuable prognostic information.
- Micrometric substaging appears superior for clinical utility and reproducibility.
- Standardization and validation of T1 substaging techniques could optimize bladder cancer management.
