Overall Grade
The scores for each of these three criteria are added together to give a final overall score and a corresponding grade as follows:
- 3-5 Grade 1 tumor (well-differentiated). Best prognosis.
- 6-7 Grade 2 tumor (moderately-differentiated). Medium prognosis.
- 8-9 Grade 3 tumor (poorly-differentiated). Worst prognosis.
Lower grade tumors, with a more favorable prognosis, can be treated less aggressively, and have a better survival rate. Higher grade tumors are treated more aggressively, and their intrinsically worse survival rate may warrant the adverse effects of more aggressive medications.

Famous quotes containing the word grade:
“Life begins at six—at least in the minds of six-year-olds. . . . In kindergarten you are the baby. In first grade you put down the baby. . . . Every first grader knows in some osmotic way that this is real life. . . . First grade is the first step on the way to a place in the grown-up world.”
—Stella Chess (20th century)
“Ideas are like pizza dough, made to be tossed around, and nearly every book represents what my son’s third grade teacher refers to as a “teachable moment.””
—Anna Quindlen (b. 1952)
