What is the maximum Gleason score achievable?

Explanation:
The key idea is that the Gleason score is the sum of the two most common tumor patterns, each graded on a 5-point scale. The highest grade is 5, so the maximum sum is 10, achieved when both predominant patterns are grade 5. This score reflects how poorly differentiated the cancer is, with higher numbers indicating more aggressive disease. While earlier reports sometimes used lower base patterns, the theoretical maximum remains 10.
