“…[21][22][23][24] However, there are few studies of observer variability in thyroid US except for some reports about the volume of thyroid nodules. [25][26][27] The current study showed a relatively high degree of consistency among multiple observers in US evaluation of thyroid nodules. The characteristic of internal content (solid versus cystic) showed substantial agreement, and the shape, echogenicity, calcification, and diagnostic categories showed moderate agreement.…”

“…We recommend the definition of nodule growth as a 20% increase in the nodule diameter (with a minimum increase in two dimensions of at least 2 mm) or a 50% increase in the nodule volume, according to the American Thyroid Association guidelines [3] . The previously mentioned criteria of nodular growth permits to overcome the reported interobserver's variability allowing the determination of true change in size [38,44] .…”

“…Nodules were defined as having size change on US with changes larger than 2 mm which is a commonly accepted criterion [17,29] and 3 mm which is the smallest measurement bias [30][31][32]. The size changes of malignant and benign nodules were evaluated using the mixed model and the formula of size changes based on the mixed model was estimated and compared on a per-lesion basis.…”

Thyroid nodules ≤5 mm on ultrasonography: are they “leave me alone” lesions?

The incidence of small thyroid malignancy has increased. However, there is no evidence-based guideline for managing thyroid nodules ≤ 5 mm on ultrasonography (US). We evaluated how to manage thyroid nodules ≤ 5 mm. Thyroid nodules ≤ 5 mm in size on US that had undergone surgery and US-guided fine-needle aspiration were eligible. A total of 3,117 thyroid nodules in 3,012 patients were included. The size changes of malignant and benign nodules during follow-up were evaluated. Thyroid malignancies were classified according to follow-up and surgery time within and after 12 months. Clinico-pathological characteristics were compared. Of 3,117 nodules, 1,639 nodules in 1,619 patients were benign and 1,478 in 1,427 were malignant. Only 5.8 and 1.2 % of malignant nodules and 6.8 and 4.2 % of benign nodules increased in size when a 2-mm and 3-mm change on US were referenced. Of 1,079 patients with an index malignancy ≤ 5 mm, extrathyroidal extension, lymph node metastasis, recurrence, and mortality were not significantly different between patients with and without follow-up and between patients with surgery within 12 months and after 12 months. None of the patients who underwent surgery had distant metastasis and none died of thyroid malignancy. In thyroid nodules ≤ 5 mm found on US, US-FNA could be recommended in cases of increased size during US follow-up if lateral LNM was not found because a delay in surgery did not impact cancer recurrence and mortality.
