BACKGROUND Stimulated thyroglobulin (Tg) ≤1 ng/mL after thyroidectomy (after L-thyroxine [L-T4] withdrawal or administration of recombinant human thyrotropin [rhTSH]) has been proposed as a criterion to spare patients with papillary thyroid cancer (PTC), who are at low risk of recurrence, from ablation with iodine-131 ((131)I). The objective of this(More)
BACKGROUND Epidemiological studies have shown a higher risk of thyroid cancer among individuals who have a relative with papillary thyroid cancer (PTC) compared to those without a family history. This study evaluated the prevalence of thyroid cancer among subjects with only one first-degree relative (sibling) with PTC who had no palpable nodules, factors(More)
BACKGROUND Diagnostic radioiodine whole-body scanning (DxWBS) in combination with stimulated thyroglobulin (Tg) (i.e., measurement after levothyroxine [L-T4] withdrawal or recombinant human TSH administration) continues to be recommended for patients with differentiated thyroid carcinoma (DTC) at high or intermediate risk for recurrence with negative basal(More)
BACKGROUND In patients with differentiated thyroid carcinoma considered to be free of the disease after initial therapy, the appropriate timing or necessity of subsequent stimulated thyroglobulin (Tg) testing is uncertain. The objective of this study was to determine the value of a repeat stimulated Tg in patients considered to be free of disease 6-12(More)
BACKGROUND The objective of this study was to report the results of a series of 12 patients with papillary carcinoma aged 16 years or younger, who were prepared with recombinant human TSH (rhTSH) for remnant ablation with (131)I. The TSH levels achieved and the safety of 24 cycles of rhTSH administration (ablation and control assessment) are reported. (More)
It has been proposed that, in patients treated for well-differentiated thyroid carcinoma, undetectable basal thyroglobulin (Tg) levels measured with a highly sensitive assay in the absence of anti-thyroglobulin antibodies (TgAb) and combined with negative neck ultrasonography (US) ensured the absence of disease. We report a series of five patients with(More)
BACKGROUND In the presence of anti-thyroglobulin antibodies (TgAb), serum thyroglobulin (Tg) might be underestimated. Therefore, the American Thyroid Association does not recommend serum Tg after thyroid hormone withdrawal or recombinant human thyrotropin administration (stimulated Tg) and diagnostic whole-body scanning (DxWBS) in TgAb-positive patients who(More)
