gleason patterns

What are the Limitations of the Gleason Grading System?

While the Gleason grading system is widely used, it has some limitations:
- Subjectivity: Interpretation of histological patterns can vary among pathologists, leading to inter-observer variability.
- Sampling Error: A biopsy sample may not capture the most aggressive part of the tumor, potentially underestimating the Gleason score.
- Evolution of Cancer: Prostate cancer can evolve over time, and the initial Gleason score may not reflect the current state of the disease.
