Ultralydskanning ved recidivmonitorering for thyroideacancer

The commonly used tumour-node-metastasis (TNM) staging system is designed to predict death and not recurrence. Based on this, patients with thyroid cancer are grouped into risk categories at the time of initial treatment. However, recent guidelines proposed a novel staging system focusing on microscopic invasion into the perithyroidal tissues, neck lymph node involvement and 131I uptake outside the thyroid bed following treatment. This risk re-assessment improves the prediction of recurrent/persistent disease. The cornerstone in the follow-up is measurement of plasma-thyroglobulin concentration and ultrasound of the neck focusing on the thyroid bed and classification of lymph nodes according to their location and high risk signs.
