Introduction: Surgery for benign nodular goiter (NOD) is currently limited to cancer or cosmetic deformities. Most patients are, in principle, followed up for years or decades. The long-term outcome, however, is not always clear.Patients and methods: NOD was diagnosed as benign in 1,825 patients (1990–2015). 102 patients (5%) were treated by surgery. 95% returned to home doctors (69%) or continued to visit our clinic (518 patients, 31%). Follow-up e...

Background: Nodular goiter (NOD) is one of the most common disease (69% in our thyroid clinic). Although the nodular growth is generally slow, it may be influenced by thyroid hormones, autoimmunity or other factors. The analysis may contribute to predict the outcomes.Patients and methods: 2,213 Japanese patients (2007–2018; Fukushima coast area) with NOD were enrolled in this study. Mean observation period was 6.4 years with 7 visits (1–50). Th...

Nodular goiter (ND) is increasingly found by image analysis. The long-term course of ND, however, is not necessarily clear and may differ in locality. The present study analyzed the changes of ND in Japanese, taking iodine-rich foods, during follow-up periods.Patients and methods: Patients (n=4,229) were followed up to 28 years (3.4±5.8 years). Volume of nodules (VOL) by ultrasonography (US) and laboratory data, including thyroid hormones (...
