Thyroglobulin levels and thyroglobulin/thyrotropin ratio could predict the success of the ablative/therapeutic <sup>131</sup>I in the differentiated thyroid cancers.
Thyroglobulin transcripts were detected in nine of nine patients with metastatic thyroid cancer, seven of 78 patients with thyroid cancer and no current metastases (although of these seven patients, five had a history of metastatic disease that had been previously treated by surgery, one had a coexisting parathyroid cancer, and one had both papillary and follicular thyroid cancers), zero of six patients with benign thyroid disease, and zero of seven normal volunteers.
After thyroidectomy and remnant (131)I ablation, serum Tg is a specific and sensitive marker for the presence of thyroid cancer tissue, and its measurement is fundamental in the follow-up of patients affected by differentiated thyroid carcinomas (DTCs), being even more sensitive than diagnostic whole-body scan.
All patients with follicular cell-derived thyroid cancer (TC) who had thyroglobulin measured using LC/MS assay from November 1, 2013, to November 7, 2014, were evaluated.
Among these, thyroglobulin, and more recently thyroid-stimulating hormone receptor mRNAs' provide high diagnostic sensitivity and specificity for thyroid cancer detection.
Cotransduction of AdTTF-1 and AdTGTK permitted 90% cytotoxicity for BHP15-3 and >95% cytotoxicity for FRT, as well as for BHP7-13 and BHP18-21v thyroid cancer cell lines [both/TTF1(-)/TTF-2(-)/Pax-8(+)/TG(-)].
Detection of thyrotropin-receptor messenger ribonucleic acid (mRNA) and thyroglobulin mRNA transcripts in peripheral blood of patients with thyroid disease: sensitive and specific markers for thyroid cancer.
Factors associated with the higher amount of radiation exposure from the patients to the household environment were patient body weight (P = .025, univariate analysis; P = .037, multivariate analysis, odds ratio [95% confidence interval] 1.067 [1.004-1.134]) and distant metastases based on I post-therapy scanning (P = .041, univariate analysis; P = .058, multivariate analysis, odds ratio [95% confidence interval] 6.453 [0.938-44.369]); age, sex, body mass index, renal function, serum stimulated thyroglobulin level, and recombinant human thyroid-stimulating hormone use were not associated with the amount of radiation exposure from the patients to the household environment.Higher body weight and distant metastases may be the best predictors for higher radiation exposure to the household environment from patients with thyroid cancer after RAI therapy.
Fine needle aspiration cytology (FNAC) and washout thyroglobulin (Tg) measurements are the standard for evaluating a metastatic lymph node (LN) in thyroid cancer.
Histologically and immunohistochemically, the tumors resembled poorly differentiated thyroid cancers in humans, demonstrating a solid growth pattern with sheets of round or spindle-shaped cells, decreased expression of thyroglobulin, and a tendency to lose E-cadherin.
Posttreatment surveillance of thyroid cancer is done with US of the thyroid bed as well as monitoring of tumor markers such as serum thyroglobulin and serum calcitonin.
