- tumor size
- invasion
Gleason score
Used in prostate cancer
Measures level of differentiation and growth pattern
*add 2 scores together
Gleason score = 6
well differentiated (more like normal prostate tissue) *good prognosis/low risk
Gleason score 7
moderately differentiated
Gleason score 8-10
poorly differentiated
* poor prognosis/high risk
