Gleason grading

Histological grading. A score of 1 to 5 is assigned to each of the two largest areas of tumor involvement in the samples obtained, based on the worst feature.

  • 1 = aggressive.
  • 5 = most aggressive.

These two scores are then added together to a Gleason score of 2 - 10.

  • 2 - 4 = low grade
  • 5 - 8 = intermediate grade
  • 9 - 10 = high grade

As this is obtained on biopsy specimens and correlates to prognosis, it enables treatement to be tailored.
