Overview: | |||
*This system is only one any one talks about. | |||
*Score range: 6-10. | |||
*Score range: 2-10. | **Technically 2-10... but almost no one uses 2-5. | ||
*Reported as on biopsy as: (primary pattern) + (secondary pattern ''or'' tertiary pattern with the highest grade) = sum. | *Reported as on biopsy as: (primary pattern) + (secondary pattern ''or'' tertiary pattern with the highest grade) = sum. | ||
**e.g. ''Gleason score 3+4=7'' means: pattern 3 is present and dominant, pattern 4 is the remainder of the tumour - but present in a lesser amount than pattern 3. | **e.g. ''Gleason score 3+4=7'' means: pattern 3 is present and dominant, pattern 4 is the remainder of the tumour - but present in a lesser amount than pattern 3. | ||
