*Tertiary Gleason pattern - definition: a pattern that is seen in than 5% of the tumour (volume), that is higher grade than the two dominant patterns.<ref name=Ref_GUP72>{{Ref GUP|72}}</ref>

**The presence of a tertiary patterns adversely affect the prognosis; however, the prognosis is not as bad as when the tertiary pattern is the secondary pattern, i.e. 3+4 tertiary 5 has a better prognosis than 3+5 (with some small amount of pattern 4).<ref name=Ref_GUP72>{{Ref GUP|72}}</ref>
