Tratment of Multinodular GoitreNCT00509483
Three-Year Follow-up of Radioiodine Therapy for Goitre
A study testing Radioactive iodine in people with Tratment of Multinodular Goitre, run by University of Sao Paulo.
Trial summary
Background: Preadministration of recombinant human thyrotropin (rhTSH) increases the amount and homogeneity of thyroid radioiodine uptake, and when used as an adjuvant can augment the efficiency of 131I therapy by allowing multinodular goitre (MNG) volume reduction. Read more about this study

About this study
Official title: Long-Term Follow-up and Outcome of Administering Recombinant Human Thyrotropin as an Adjuvant of Therapy With Radioiodine in the Outpatient Treatment of Multinodular Goitres
Background: Preadministration of recombinant human thyrotropin (rhTSH) increases the amount and homogeneity of thyroid radioiodine uptake, and when used as an adjuvant can augment the efficiency of 131I therapy by allowing multinodular goitre (MNG) volume reduction.
Objective: The investigators aimed to assess low-dose rhTSH-aided fixed-activity radioiodine therapy outcome in MNG patients.
Design: This was a long-term (36 months) observational study. Methods: The investigators measured 24 h thyroid radioiodine uptake (RAIU) of 1.4 µCi (0.5 MBq) of 131-iodine at baseline and 24 h after intramuscular injection of 0.1 mg rhTSH in 42 patients (aged 42-80 years) who subsequently received 30 mCi 131-iodine 24 h after an identical rhTSH injection. Urinary iodine was measured at baseline and at 3 months after following a low iodine diet. TSH, free thyroxine (FT4), T3 (T3) and thyroglobulin (TG) were measured at baseline, 24 h, 48 h, 72 h, 168 h, one month, 3, 6, 9, 12, 18, 24 and 36 months after therapy. Thyroid volume was assessed by computer tomography at baseline and every 6 months thereafter.
