Outcomes of surgery and radioiodine treatment for neck recurrence in papillary thyroid cancer.

Purpose: Persistent/recurrent disease in the neck is frequent in patients with papillary thyroid cancer (PTC). The goal of this study was to evaluate the efficacy of the reoperation and radioiodine (RAI) treatment for persistent/recurrent disease after the initial treatment.

Methods: A total of 30 patients (13 M/17 F) with PTC were enrolled in this study.

Thyroid ultrasonographic charasteristics and Bethesda results after FNAB.

Purpose: Thyroid nodular disease (TND) is a frequent clinical problem and the major concern is the probability of malignancy in a solitary nodule or in one or more nodules of a multinodular goiter. For this purpose, neck ultrasound and fine needle aspiration biopsy (FNAB) under ultrasound guidance have been established as the initial investigation of choice.

Methods: A total of 1113 patients (210 male/903 female) underwent FNABs for the same number of thyroid nodules.

Biochemical Effects of Levothyroxine Withdrawal in Patients with Differentiated Thyroid Cancer.

Background: Patients with differentiated thyroid carcinoma (DTC) are submitted to withdrawal of levothyroxine (LT4) aftter thyroidectomy, in order to undergo radiodine ((131)I) treatment.

Patients And Methods: A total of 345 patients with a history of DTC were enrolled in the study. Their biochemical profile and serum free triiodothyronine (FT3), free thyroxine (FT4) and thyrotropin (TSH) levels were measured during withdrawal of LT4 treatment, and several months after restarting LT4.
