Partially cystic thyroid nodules (PCTNs) are common on ultrasound (US). However, there are insufficient data on the prevalence of thyroid carcinoma among such nodules. The purpose of this study was thus to evaluate the prevalence and differentiation of partially cystic thyroid cancers in US-guided fine needle aspiration (FNA).A total of 1342 consecutive patients with 1360 thyroid nodules underwent prospective US diagnosis and FNA biopsy. In total, 281 nodules (20.7%) were partially cystic lesions. The nodules were prospectively analyzed based on US features (ie, solid portion positions, shapes, margins, and microcalcifications) and US diagnosis (benign, suspicious, or malignant)...

OBJECTIVE: Clinical stage (cStage) in thyroid cancer determines extent of surgical therapy and completeness of resection. Pathologic stage (pStage) is an important determinant of outcome. The rate of discordance between clinical and pathologic stage in thyroid cancer is unknown. METHODS: The National Cancer Data Base (NCDB) was queried to identify 27,473 patients ≥45 years old with cStage I through IV differentiated thyroid cancer undergoing surgery from 2008-2012...

Improvement in the clinical outcome of human cancers requires characterization of genetic alterations underlying their pathogenesis. Large-scale genomic and transcriptomic characterization of papillary thyroid carcinomas (PTCs) in Western populations has revealed multiple oncogenic drivers which are essential for understanding pathogenic mechanisms of this disease; while so far, the genetic landscape in Chinese patients with PTC remains uncharacterized. Here, we conducted a largescale genetic analysis of PTCs from patients in China to determine the mutational landscape of this cancer...

Chylous leakage is a complication of thyroidectomy accompanied by bilateral neck dissection with incidence of 0.5-6.2%. A 51-year-old female patient underwent total thyroidectomy, bilateral and central neck dissection for papillary thyroid carcinoma. In post-operative 4(th) day, left sided chylous leakage was observed as 1,500 cc/day through neck drain. Leakage did not cease after 1-month conservative treatment so single port thoracoscopic intervention was performed. Under general anesthesia, patient was placed in left lateral decubitus position...

Thyroid cancer has a very well-known propensity for nodal involvement, either in the central and lateral neck compartments. Neck dissection addressing the central compartment may be performed with an elective or therapeutic intent, the former concomitantly to a thyroidectomy whereas the latter may be accomplished also as a revision procedure for recurrent disease. In this paper complications of central compartment neck dissection will be described, analyzing separately primary and revision procedures.

Background: The use of intraoperative neuromonitoring (IONM) provides surgeons with real time information about recurrent laryngeal nerves (RLN) functional integrity. Hence, allowing them to modify the initially scheduled bilateral procedure, to a two-stage thyroidectomy in cases of loss of signal (LOS) on the first side of resection resulting in minimization of bilateral RLN injury. The purpose of our study was to present our results since the implementation of the above mentioned process in both malignant and benign thyroid disease...

Ultrasonography is pivotal in triage thyroid biopsy in the era after the identification of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). This pictorial essay illustrates the pathologic basis of the sonographic features that distinguish NIFTP from thyroid cancers. In this study, we present the correlations of ultrasonography to ×1 histopathology to assess shape and margin characteristics. Markedly hypoechoic nodules correlate to microfollicular/solid nodules, while isoechoic/hyperechoic thyroid nodules correlate to normofollicular/macrofollicular nodules...

Ultrasonography is the first choice of lymph node metastasis (LNM) detection which is crucial for therapeutic options of papillary thyroid cancer (PTC). However, the sensitivity of ultrasonography in detecting LNM of PTC is relatively low; especially in central LNM. MiR-324-5p has been reported to play important roles in the metastasis of various cancers. To explore the relationship between miR-324-5p and LNM in PTC, quantitative real-time polymerase chain reaction was performed in PTC tissue and fine needle aspiration (FNA) washout successively...

Histological findings often display an association between papillary thyroid carcinomas (PTC) and autoimmune thyroiditis (AIT) and so differ significantly from follicular thyroid carcinomas (FTC). The aim of this interdisciplinary, retrospective study was to evaluate the association of AIT in patients with PTC and FTC and a control group of benign nodular goiters. One hundred thyroidectomies with histologically confirmed differentiated thyroid carcinomas, 67 with PTC and 33 with FTC, were submitted for examination...

BACKGROUND: The BRAF V600E mutation is highly specific for papillary thyroid carcinoma (PTC). A test for this mutation can increase the diagnostic accuracy of fine-needle aspiration cytology (FNAC), but a considerably high false-negative rate for the BRAF V600E mutation on FNAC has been reported. In this study, we investigated the risk factors associated with false-negative BRAF V600E mutation results on FNAC. METHODS: BRAF V600E mutation results of 221 PTC nodules between December 2011 and June 2013 were retrospectively reviewed...

INTRODUCTION: False-negative thyroid fine-needle aspirates (FNA) are not well characterized. METHODS: We correlated the results of all thyroid aspirations from 1997 to 2016 with histologic follow-up. RESULTS: There were 13,733 aspirates, 2,112 (15.3%) resections, and 678 malignancies (32.1%). Eighteen (2.7%) false-negative cases were identified (interpretation, n = 6; sampling, n = 7; and new nodules, n = 5). Interpretive false-negative cases were significantly less likely when the indeterminate rate was greater than 13% (p = 0...

BACKGROUND: Fluorine-18 fluorodeoxyglucose positron emission tomography/CT ((18) F-FDG PET/CT) has been widely accepted as an effective method for detecting recurrent papillary thyroid cancer (PTC) in patients with increased serum thyroglobulin (Tg) or Tg antibody (TgAb) levels and negative whole-body scintigraphy (WBS) results. The role of WBS as a diagnostic tool in detecting recurrence has relatively decreased recently. However, only a few studies have examined the usefulness of (18) F-FDG PET/CT for evaluating patients with recurrent PTC, regardless of the WBS results...

BACKGROUND: Papillary thyroid carcinoma has excellent survival, yet recurrence remains a challenge. We sought to determine the proportion of reoperations performed for persistent, rather than truly recurrent, disease. METHODS: We conducted a retrospective review of a prospectively maintained database. Patients with papillary thyroid carcinoma who underwent reoperation for disease from 2000-2016 were included. We defined recurrence as disease that developed after a patient had an undetectable thyroglobulin and a negative ultrasonography within 1 year of operation...
