Introduction: The prediction of the risk of recurrence in differentiated thyroid cancer (dtc) in chile is different from ata. The use of the stimulated thyroglobulin (tg) post-surgery in the prediction of the risk is controversial. We present a cohort applying a new local protocol that includes the tg for supporting the discrimination of the patients for offer low doses or radio iodine.
Objective: Asses if the local risk classification (lc) allow us to discriminate the response to the treatment (rt).
Method: Analysis of medical records from the patients with total thyroidectomy for dtc during 2013. Compared the lc with de ata risk stratification scale. We evaluated the response to the treatment after a year of evolution according with the levels of suppressed and stimulated tg and images. The results were divided in excellent or acceptable/incomplete.
Results: 96 patients were analysed. The thyroidectomy was total in a 100%. Histological type: 92.7% papillary. 68.7% received radio iodine in doses from 30 to 150 mci; in the group of very low risk lc no one went to ablation. Rt was excellent in 74%, acceptable in 20% and incomplete in 6.2%. Using the cohort value of the tg lower than 2 ng/dl, we get un lr of 0.22 for predicting a good response.
Conclutions: In the local classification all the patients with very low risk presented excellent response to the treatment, allowing discriminate better this group.
