[Postoperative radioiodine ablation in patients with low risk differentiated thyroid carcinoma].
Most patients with newly diagnosed differentiated thyroid carcinoma have tumors with low risk of mortality and recurrence. Standard therapy has been total or near total thyroidectomy followed by postoperative radioiodine remnant ablation (RRA). Although RRA provides benefits, current clinical guidelines do not recommend it universally, since an increase in disease-free survival or a decrease in...
متن کاملExtrathyroidal uptake from thyroid carcinoma on 99mTc-pertechnetate scintigraphy.
Three cases of imaging with 99mTc-pertechnetate (99mTcO4) and unusual positive lymph node uptake in the neck are reported hereby. Two cases were later diagnosed to be well-differentiated thyroid carcinoma, (DTC) with nodal metastasis. The third was a confirmed case of carcinoma thyroid that had presented with mass in the neck soon after surgery, being prepared for ablative dose of radioactive i...
متن کاملFine-needle aspiration cytology and (99m)Tc-pertechnetate scintigraphy together in patients with differentiated thyroid carcinoma.
The aim of this study was to evaluate the usefulness of fine-needle aspiration cytology (FNAC) and (99m)Tc-pertechnetate scintigraphy (TS) together in patients with differentiated thyroid carcinoma. Data from a series of 357 patients (284 women and 73 men, median age 43 years, range 19-73) with solitary thyroid nodule and no signs of hyperfunction, who had undergone both FNAC and TS prior to su...
متن کاملPreablation Imaging Before Radioiodine Ablation in Differentiated Thyroid Carcinoma
Detection of residual tissue after thyroidectomy for papillary or follicular thyroid carcinoma may be performed using diagnostic imaging with either 123I or 131I. The former is often preferred to avoid ‘‘stunning’’—defined as a reduction in uptake of the therapeutic dose of 131I caused by some form of cell damage from the diagnostic dosage of the radionuclide. Stunning could potentially reduce ...
متن کاملRadioiodine-remnant ablation in low-risk differentiated thyroid cancer: pros.
Differentiated thyroid carcinomas are typically treated with total thyroidectomy as initial therapy. Subsequent radioactive iodine (RAI) ablation destroys post-surgical thyroid remnants, can additionally provide adjuvant therapy of residual and metastatic thyroid cancers, and enhances the sensitivity and specificity of further diagnostic studies. There is current controversy regarding whether a...
