Although grades 1 and 2 appear different, they are now
reported as a grade 3 as they have the same outcomes.
A pure grade 3 cancer is unlikely to ever metastasize.
The Gleason score is most often obtained by adding the
number of the most common Gleason pattern with the
second most common. The lower the score, the less
aggressive the cancer and the less likely it is to
progress. It's important when interpreting a Gleason
score to understand that the order of the numbers is
highly significant, as the first number is always the most
prevalent type of pattern found. So even if the total is 7,
a Gleason score of 4 + 3 = 7 is worse than a Gleason
score of 3 + 4 = 7. That's because 4 indicates a more
aggressive cancer so if it is the most prominent in all of
the cores, that's worse than if 3 was the most prominent.
A new system has now been developed which makes it
a lot easier to understand the Gleason score and how
high risk the prostate cancer is. The Gleason scores are
reported in Grade Groups.
