Once the primary and secondary patterns have each received a score from one to five, these two numbers are added together, resulting in a total Gleason score between 2 and 10 with two representing low-grade tumors and 10 representing high-grade, dangerous tumors.
主要分级区和次要分级区分别打分1-5，二者之和即Gleason评分的总分，范围为2-10，2代表低分级肿瘤，10代表高分级高危肿瘤。
