SummaryAim: In radioiodine therapy (RIT) of benign thyroid-disorders empirical half-lives (HLemp) may be used to calculate therapeutic dose. In this study the effective half-life (HLf as well as potential influence factors were retrospectively determined in order to better estimate HLemp.Methods: Data from patients undergoing RIT from 01/09 to 04/14 were analysed (empirically estimated HLeff stratified by metabolic state and diagnosis). Inclusion criteria were: Benign thyroid-disorders, singular capsule administration and ≥ 6 dosimetry time-points (i. e. > 72 h inpatient stay). The effects of metabolic state, previous thy- reostatic medication and sex on HLeff were assessed by non-parametric ANOVA. The effects of target-volume and patient-age were assessed by regression analysis and nonparametric correlation (Spearman).Results: Data of 1,498 patients were analyzed: Graves’ Disease (GD), n = 286; multinodular goiter/disseminated autonomy (AMG/DA), n = 751; autonomous thyroid nodules (ATN), n = 421; euthyroid goiter (EG), n = 40. Mean HLeff (days ± SD) was 5.4 ± 1.5 in GD, 6.6 ± 1.2 in AMG/DA, 5.5 ± 1.6 in ATN and 6.9 ± 0.7 in EG. HLeff differed by metabolic state in GD, AMG/DA, and ATN, whereas neither thyreos- tatic medication nor sex were relevant. Moreover, target-volume (all diagnoses) and age (ATN and GD only) were associated with HLeft although the effect was small (R2 < 3.8%).Conclusion: When using standard HLeff for RIT, diagnosis and metabolic state should be considered for dose-calculations in RIT. Despite partial significance, the effects of target-volume and patient-age are small and a correction of HLeff, for these factors doesn’t appear to be necessary in a routine setting.

ObjectiveIodization 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.DesignA nationwide register study.MethodsInformation on operations and radioiodine treatments for benign thyroid disorders was extracted from nationwide registers in the years 1990 to 2007. Treatment rates are presented for surgery and for radioiodine separately, and as a combined rate, both nationwide and split by the regions of prior mild and moderate ID.ResultsA total of 65 605 treatments were identified: 26 456 operations and 39 149 radioiodine treatments. In the first years of iodization (1998–2000; rate ratio 2000/1997), the combined treatment rate increased with 2.5% (95% confidence interval (CI): −1.8–7.1). Split by prior ID level, the increase was seen in the region of moderate ID, but a decrease was seen in the region of mild ID. After 2000, the combined rate decreased, and ended up being 11.1% (95% CI: 7.1–15.0) lower in 2007 than before iodization (rate ratio 2007/1997). The changes were primarily due to changes in the use of radioiodine therapy as the surgery rates remained almost constant.ConclusionsIodization seemed to be associated with a temporary increase in the utilization rate of surgery and radioiodine therapy in the region of prior moderate ID, probably as a result of treatment of iodine-induced hyperthyroidism, but the rates ended up being lower than before iodization.
