BACKGROUND: Current guidelines advocate no prophylactic dissection of the lateral neck compartment for papillary thyroid carcinoma (PTC) without clinical evidence of lateral neck metastasis (cN1b). However, lateral neck recurrence can affect patient treatment outcomes and quality of life. Therefore, this study examined the risk factors for lateral neck recurrence after the definitive treatment of PTC without cN1b. METHODS: The study enrolled 1928 consecutive patients who underwent total thyroidectomy between 2006 and 2012 for PTC without cN1b...

Novel molecular-targeted treatments show great prospects for radioiodine-refractory and surgically inoperable thyroid carcinomas. While aberrations in protein-coding genes are a focus in molecular thyroid cancer medicine, the impact of oncogenes on the expression of long noncoding RNAs (lncRNAs) has been largely uncharacterized. We aimed to identify the expression patterns of lncRNAs and mRNAs in high-throughput molecular profiles of 18 papillary thyroid cancer (PTC) patients. We identified 452 mRNAs and 240 unannotated lncRNAs that were differentially expressed in PTC...

The objective of this study was to prospectively evaluate the diagnostic accuracy of contrast-enhanced ultrasonography (CEUS) in differentiating between benign and metastatic cervical lymph nodes in patients with papillary thyroid cancer (PTC). Three hundred nineteen cervical lymph nodes (162 metastatic from PTC and 157 benign) were evaluated using conventional ultrasonography (US) and CEUS before biopsy or surgery. Metastatic lymph nodes more often manifested centripetal or asynchronous perfusion, hyper-enhancement, heterogeneous enhancement, perfusion defects and ring-enhancing margins than benign lymph nodes at pre-operative CEUS (all p values < 0...

BACKGROUND: Composite pheochromocytoma/paragangliomas are very rare tumors composed of ordinary pheochromocytoma paragangliomas associated with neurogenic tumors. Several hereditary susceptibility disorders are known to be associated with pheochromocytoma/paragangliomas such as multiple endocrine neoplasia type 2 (2A or B). To the best of our knowledge, only four cases of composite pheochromocytoma/paragangliomas associated with multiple endocrine neoplasia type 2 have been reported. CASE PRESENTATION: A 40-year-old Arabic woman presented with headache, palpitations, paroxysmal hypertension, and weight loss, which she had had for the last 3 years...

We have previously shown that galectin-4 expression is an independent predictor for lymph node metastasis and serves as an adverse prognostic indicator in patients with acinar adenocarcinoma of the lung. In contrast, thyroid transcription factor-1 (TTF-1) expression in non-small cell lung carcinoma has been shown to be associated with a favorable prognosis. In the present study, 208 cases of acinar adenocarcinoma of the lung and 36 cases with distant metastatic lesions of lung adenocarcinoma were immunohistochemically examined for expression of galectin-4 and TTF-1 to elucidate their correlation with clinicopathological factors...

BACKGROUND: We investigated the expression of angiopoietins in patients with papillary thyroid carcinoma (PTC) and the role of angiopoietins as biomarkers predicting the aggressiveness of PTC. METHODS: Expression of angiopoietins was evaluated by immunohistochemistry of tumor specimens from patients with PTC. We demonstrated potential correlations between expression of angiopoietins and clinicopathologic features. RESULTS: High expression of Ang-1 was positively correlated with a tumor size >1 cm, capsular invasion, extrathyroid extension, lymphovascular invasion, lymph node metastasis, and recurrence (P < 0...

REVIEW
June Young Choi, Kyung Ho Kang
Bilateral axillo-breast approach (BABA) robotic thyroidectomy has been performed since 2008, and the indications of the BABA robotic operation has been widened to the robotic modified radical neck dissection (MRND). The indication for BABA robotic MRND is suspicious lateral neck metastasis of well-differentiated thyroid carcinoma, and the contraindication is far advanced carcinoma such as encasement of common carotid artery. Surgical procedures start from flap formation as a routine BABA robotic thyroidectomy and the lateral neck dissection is performed from level IV and Vb to level III and IIA...

Despite the relatively high prevalence of thyroid cancer, the occurrence of multiple synchronous, distinct subtypes of primary thyroid carcinoma is uncommon. The incidental finding of papillary thyroid microcarcinoma in a gland with a biologically relevant follicular or medullary carcinoma is more frequent than the synchronous occurrence of multiple clinically significant carcinomas. We report a case of synchronous papillary and follicular thyroid carcinomas metastatic to lymph node and bone, respectively. Next generation sequencing showed BRAF V600E mutation in the primary papillary carcinoma and NRAS Q61R mutation in the primary follicular carcinoma and bony metastasis...

Anaplastic thyroid cancer is the rarest tumour of the thyroid gland, representing only 2% of clinically recognised thyroid cancers. The most common metastatic sites are lungs, followed by the intrathoracic and neck lymph nodes. We report the case of a 62-year-old woman who presented to our setting with multiple soft tissue nodules, thyroid mass, head swelling and weight loss. Radiological investigation showed a large thyroid mass with widespread metastasis in subcutaneous tissues of both upper limbs, chest and abdomen...

Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1-3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it...

BACKGROUND: Compared with conventional papillary thyroid carcinoma (PTC), follicular variant of PTC (FV-PTC) shows less aggressive behavior and better prognosis. Nonetheless, regional lymph node (LN) metastasis was found in 22.8% of FV-PTC patients. Because LN metastasis is a proven predictor of recurrence in PTC, it is important to assess LN metastasis in FV-PTC patients. METHODS: We retrospectively reviewed 134 FV-PTC patients who underwent thyroidectomy with neck dissection...
