↵* TNM: all patients initial M0.
↵† For comparison, thyroglobulin levels under TSH suppression are given at time of 68Ga-DOTATOC PET/CT.
↵‡ Tg values were borderline under TSH suppression but elevated and rising under TSH stimulation.
↵¶ Patient was excluded from thyroglobulin analysis because he presented, in addition to elevated and rising thyroglobulin levels, with increasing thyroglobulin antibodies (TgAb) during follow-up.
Tg = thyroglobulin.
