How to Discuss the Gleason Score with a Patient
When discussing the Gleason score with a patient, focus on explaining it as a measure of cancer aggressiveness that guides treatment decisions and helps predict outcomes. 1
Explaining the Basics of the Gleason Score
- The Gleason score is determined by a pathologist who examines prostate tissue samples under a microscope to evaluate how much the cancer cells differ from normal prostate cells 1
- Explain that the score is calculated by adding the grades of the two most common cancer patterns seen in the biopsy, with each pattern scored from 1 to 5 2, 1
- Clarify that Gleason scores range from 6 to 10 in clinical practice, with higher scores indicating more aggressive cancer cells 1
- Mention that Gleason scores of 2 to 4 are uncommon, and most detected tumors range from 5 to 10 2
Breaking Down the Gleason Score Ranges
- Gleason score 6 (3+3): Describe as well-differentiated cancer cells that look similar to normal cells and tend to grow slowly 1, 3
- Gleason score 7: Explain the important distinction between 3+4 and 4+3 patterns:
- Gleason scores 8-10: Describe as poorly differentiated cancer cells that look very different from normal cells and tend to grow more rapidly 1, 5
Explaining Risk Stratification
- Show how the Gleason score contributes to risk categorization along with PSA level and clinical stage 2:
Discussing Treatment Implications
- Explain that with each increase in Gleason score, there is an increase in cancer aggressiveness, which influences treatment recommendations 2
- For Gleason score 6: Active surveillance may be appropriate for many patients 1
- For Gleason score 7: Treatment options may include surgery or radiation, depending on other factors 4
- For Gleason scores 8-10: More aggressive treatment approaches are typically recommended 5
Communication Tips
- Use simple language and visual aids when explaining the scoring system 1
- Avoid medical jargon and explain that the Gleason score is just one factor in treatment decision-making 2
- Acknowledge the anxiety that can come with cancer diagnosis and provide reassurance about treatment options 2
- For minimal tumor findings on biopsy, explain that the assigned Gleason score may have limitations in predicting outcomes 6
- Emphasize that even Gleason score 6 cancers are still malignant, though they typically have an excellent prognosis with appropriate management 3
Important Caveats
- When discussing minimal cancer on biopsy (less than 1 mm or 5% of one core), explain that the Gleason score may be less reliable in predicting final pathology 6
- For patients with tertiary patterns (a small component higher than the two main patterns), explain how this might affect prognosis 2
- Clarify that the Gleason score at initial diagnosis may not reflect the current state of metastatic disease if the cancer has progressed 7
