BACKGROUND To detect recurrent disease in patients who have had differentiated thyroid cancer, periodic withdrawal of thyroid hormone therapy may be required to raise serum thyrotropin concentrations to stimulate thyroid tissue so that radioiodine (iodine-131) scanning can be performed. However, withdrawal of thyroid hormone therapy causes hypothyroidism. Administration of recombinant human thy...
AIM The aim of this study was to compare the efficacy and adverse effects of radioiodine (131I) therapy between two groups of patients with low-risk differentiated thyroid cancer (DTC) who received 30 mCi or 100 mCi radioiodine for ablation of the thyroid remnant after total thyroidectomy. METHODS The study cohort was 173 patients, 85 of whom were given 30 mCi of radioiodine and the others we...
OBJECTIVE To present the case of a radioiodine therapy-naïve thyroid cancer patient with postthyroidectomy diplopia. CLINICAL PRESENTATION AND INTERVENTION A 63-year-old male patient presented with goiter. Histology performed after thyroidectomy proved follicular thyroid cancer. Without (131)I therapy, diplopia occurred from metastasis to the right medial rectus muscle. Improvement followed a...
We report on a high-dose radioiodine therapy after injection of recombinant human thyrotropin (rhTSH) in a 61-y-old woman with compression of the spinal cord caused by metastasis of a follicular thyroid carcinoma. Fourteen years ago, the patient underwent subtotal thyroidectomy because of multinodular goiter without any histologic evidence for malignant disease, and the patient was put on thyro...
BACKGROUND There is no consensus on the optimal treatment of multinodular goiter (MNG), but in the past few years, the use of radioiodine has increased. This study's objective was to evaluate adjuvant methimazole (MMI) therapy to increase and standardize radioiodine uptake (RAIU) with a fixed therapeutic (131)I dose of 1110 MBq (30 mCi). METHODS Our study included 5 women with MNG treated wit...
During thyroid tumor progression, cellular de-differentiation may occur and it is commonly accompanied by metastatic spread and loss of iodine uptake. Retinoic acid (RA) administration might increase iodine uptake in about 40% of patients, suggesting that RA could be a promising therapeutic option for radioiodine non-responsive thyroid carcinoma, although a prospective study with a long-term fo...
Objective SPECT/CT has numerous advantages over planar and traditional SPECT images. The aim of this study was to evaluate the role of post-radioiodine therapy SPECT/CT of patients with differentiated thyroid cancer (DTC) in early risk classification and in prediction of late prognosis. Patients and methods 323 consecutive patients were investigated after their first radioiodine treatment (11...
OBJECTIVE Iodization of salt was introduced in Denmark in 1998 because of mild-to-moderate iodine deficiency (ID). The aim of this study was to analyze the utilization rate of surgery and radioiodine therapy for benign thyroid disorders before and after the introduction of iodization, and to study a possible association between the changes and the raised iodine intake. DESIGN A nationwide reg...
Radioiodine therapy is known as the most effective treatment of differentiated thyroid carcinoma (DTC) to ablate remnant thyroid tissue after surgery. In patients with DTC treated with radioiodine, internal radiation dosimetry of radioiodine is useful for radiation risk assessment. The aim of this study is to describe a method to estimate the absorbed dose to the blood using medical internal ra...
