For example, if the most prevalent pattern/grade is 2, and the second most prevalent grade is 1, then the Gleason score is 2+1=3. If the neoplasm has only one pattern, the grade of that pattern is doubled to obtain the score. For example, if a tumor is entirely grade 1, the Gleason score would be 1+1=2.
PSA later refused to re-grade the card, as any result—whether confirming or contradicting the original PSA 10—would expose their prior misrepresentation. The buyer was refunded by the seller, but the seller—who had relied on PSA’s authentication—never recovered the nearly $1 million value of the card (Id., ¶¶ 72–106).
This stems from the practice that exams were traditionally given by 3 examiners. Each had to rate the student's examination performance on a 1–10 scale, and the final grade was the sum of the three ratings. On a 1–10 scale, passing is 6, so on a 1–30 scale the minimum passing grade is 3*6 = 18.

Those with localized tumors and PSA between 10 and 20 ng/mL are designated stage II – subdivided into IIA for Gleason grade group 1, IIB for grade group 2, and IIC for grade group 3 or 4. Stage III is the designation for any of three higher risk factors: IIIA is for a PSA level about 20 ng/mL; IIIB is for T3 or T4 tumors; IIIC is for a ...
A more refined prognosis can be established by consideration of prostate-specific antigen, and grade (i.e. Gleason score in the Gleason grading system). For example, it is common to classify patients into high, intermediate and low-risk groups on the basis of these three factors (TNM stage, PSA and Gleason score).
In simpler terms, it serves as a set of criteria for grading assignments. Typically presented in table format, rubrics contain evaluative criteria, quality definitions for various levels of achievement, and a scoring strategy. [1] They play a dual role for teachers in marking assignments and for students in planning their work. [2]
