The AMES scoring system for differentiated thyroid cancer risk stratification incorporates which parameters?
- A Age, Metastasis, Extent of primary, Size ✓
- B Age, Morphology, Extension, Stage
- C Age, Multicentricity, Extrathyroidal extension, Serum thyroglobulin
- D Angioinvasion, Macroscopic invasion, Extrathyroidal extension, Size
Correct answer: A. Age, Metastasis, Extent of primary, Size
Explanation
The AMES scoring system (Cady and Rossi, 1988) categorizes differentiated thyroid cancer risk using: Age (men >40, women >50), Metastases (distant), Extent of primary tumor (extraglandular invasion for papillary; major capsule invasion for follicular), and tumor Size (>5 cm). Low-risk patients have >98% 20-year cause-specific survival, while high-risk patients have ~50% survival. It is one of several thyroid cancer risk stratification tools alongside MACIS, TNM, and AGES.
