In the follow-up of differentiated thyroid carcinoma it is discussed whether the tumormarker thyroglobulin can replace the1311 scan, especially when the thyroglobulin serum level is normal. A positive1311 scan of metastases in the follow-up of patients with differentiated thyroid carcinoma combined with a low serum thyroglobulin level is extremely rare. The literature shows a frequency of about 4%. Recently we found 3 cases with a positive1311 scan demonstrating pulmonary and bone metastases whereas the serum thyroglobulin level was low.

Current Guidelines

Serum thyroglobulin is an essential marker during the follow-up of patients with differentiated thyroid carcinoma. Demonstration of the total absence of thyroglobulin is not possible by immunoanalytic methods if thyroglobulin antibody is present in serum samples that occur in almost 20% of patients with differentiated thyroid carcinoma. Therefore, current guidelines recommend estimation of thyroglobulin levels only if quantitative level of thyroglobulin antibody is known. However, normal thyroglobulin antibody level fails to exclude interference with the antibody, because antibody concentration within the normal range may interfere with the thyroglobulin assay. In this respect recommendations are not consistent because they distinguish only occasionally cases with normal and those with non-detectable serum thyroglobulin level. In addition, the possible impact of normal thyroglobulin antibody level on the thyroglobulin assay has not been entirely explored. Authors review literature data and current guidelines on the analytical and preanalytical limitations of the thyroglobulin and thyroglobulin antibody measurements. On the basis of their own studies, authors make recommendation for improvement of the diagnostic accuracy of the thyroglobulin measurement. Orv. Hetil., 2011, 152, 743–752.

Abstract. Serum thyroglobulin (Tg) was measured in 52 patients 3 months to 15 years (mean 5.3 years) after thyroidectomy with or without subsequent radioablation for differentiated thyroid carcinoma, before and after the interruption of suppressive thyroxine (T4) replacement therapy for 5 weeks. Whole body scintigraphy was carried out at the end of the T4 withdrawal period. Serum Tg was undetectable (< 3 μg/l) in 38 patients on T4 therapy, in 18 the scintigraphy showed a minimal accumulation in the neck region and in 20 no uptake anywhere after withdrawal of T4. In the former group Tg rose in 10 patients to 4–21 μg/l when off T4 which seemed to correspond to the normal tissue left in situ, in the latter group Tg rose only in 2 patients to 5 and 21 μg/l, respectively. Two patients out of 14 with detectable Tg on T4 had pulmonary metastases as uncovered by whole body scintigraphy (in one of them Tg rose from 12 μg/l on T4 to 1200 μg/l off T4) and 6 patients were suspected for having recidual cancer tissue (2 patients had a negative scintigraphy) because the Tg rose (66– 215 μg/l) over the upper limit of the reference range (< 50 μg/l) after T4 withdrawal. In conclusion, in the follow-up of patients with differentiated thyroid carcinoma no routine scans are needed as long as serum Tg remains undetectable but further examinations are shortly warranted when detectable Tg is obtained during T4 suppression.
