Description

The AGES (age, grade, extent, size) prognostic score can be used to estimate prognosis for  patients with papillary carcinoma of the thyroid. This can help identify patients who may need more or less aggressive therapy. The authors are from the Mayo Clinic.


Parameters:

(1) A: age

(2) G: grade

(3) E: extent

• I could not find where the grading of the tumor was defined.

 

AGES score =

= SUM(points for all 4 parameters)

 

Interpretation:

• minimum score: < 0.1

• maximum score: > 12

• The higher the score, the worse the prognosis.
