Description

Onitilo et al developed a score for staging a differentiated thyroid carcinoma. This is meant to be simpler to determine than the TNM stage. The authors are from Karolinska University Hospital, Mubarak Al-Kabeer Teaching Hospital and Kuwait University.


 

Patient selection: differentiated thyroid cancer

 

Parameters:

(1) histologic type

(2) age of the patient in years

(3) number of regional lymph nodes with metastases

(4) tumor diameter and/or extrathyroid extension

Interpretation:

• minimum score: 0

• maximum score: 15

• The higher the score the greater the risk.
