CONTEXT: A dynamic risk stratification with modified initial estimated risk based on response to therapy and disease course is one of the crucial changes adopted recently by the American Thyroid Association (ATA). This approach focuses on an individualized risk-adapted approach to the management of differentiated thyroid cancer. The BRAF V600E mutation is the most common genetic alteration in papillary thyroid cancer (PTC). However, the prognostic value of this mutation remains unclear...

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...

Papillary thyroid carcinoma (PTC) is the most common thyroid cancer with multiple risk factors including exposure to ionising radiation. Oestrogens contribute to papillary carcinoma development by promoting cell proliferation and invasion of mutated epithelial follicular cells. The present study aimed to assess ER-α and PR expression in PTC and to correlate their expression with the clinicopathological parameters in this cancer. This study included 62 primary and six metastatic papillary thyroid carcinoma cases...

Although the roles of Delphian lymph node (DLN) metastasis in papillary thyroid cancer (PTC) have been previously reported, there are still limited data on correlations of clinicopathologic factors with DLN metastasis and unique patterns of cervical node subsite metastasis in PTC patients with DLN metastasis. We retrospectively reviewed medical records of 320 patients with a diagnosis of PTC who underwent primary surgery. Clinicopathologic features and DLN metastasis patterns were analyzed for predicting extensive cervical lymph node metastasis...

BACKGROUND: Previous research suggests adolescent trauma patients can be managed equally effectively at pediatric and adult trauma centers. We sought to determine whether this association would be upheld for adolescent severe polytrauma patients. We hypothesized that no difference in adjusted outcomes would be observed between pediatric trauma centers (PTC) and adult trauma centers (ATC) for this population. METHODS: All severely injured adolescent (aged 12-17 years) polytrauma patients were extracted from the Pennsylvania Trauma Outcomes Study database from 2003-2015...

Hashimoto's thyroiditis (HT) seems to have favourable prognostic impact on papillary thyroid cancer (PTC), but data were obtained analyzing all disease stages. Given that HT-related microenvironment involves solely the thyroid, we aimed to assess relationship between HT, as detected through pathological assessment, and outcome in intrathyroidal PTC. This was a multicenter, retrospective, observational study including 301 PTC with no evidence of extrathyroidal disease. Primary study endpoint was the rate of clinical remission...

To assess the association between BRAF V600E mutation and ultrasound (US) features in papillary thyroid carcinoma (PTC) patients with and without Hashimoto's thyroiditis (HT). We retrospectively reviewed the US features and status of BRAF V600E mutation in 438 consecutive patients with surgically confirmed PTCs. The association between BRAF mutation and US features were analyzed. In addition, we conducted subgroup analyses in terms of coexistent HT. The BRAF mutation was found in 86.5% of patients (379 of 438)...

We hypothesized that cancer stem cells (CSCs) are responsible for the poor outcome and aggressive clinicopathological factors. We surveyed the expression of selected CSC markers that are specifically expressed in thyroid papillary carcinoma (PTC). A total of 80 patients with PTC from 2011 to 2012 were enrolled. We selected CD24, CD44, CD133, and dehydrogenase 1 (ALDH1), as they have been suggested to be candidate CSC markers. Expression of these markers was investigated by immunohistochemical (IHC) staining...

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...

In this study, we investigated whether bisphenol A (BPA) levels and excessive iodine intake were associated with papillary thyroid carcinoma (PTC) and nodular goiter (NG). We determined total BPA concentrations (TBC) in paired serum and urine samples, and urinary iodine concentrations (UIC) in urine samples collected from PTC patients, NG patients, and healthy individuals, then compared BPA concentrations and UIC within and between each patient group. The results showed that there was no gender-specific differences in serum TBC and UIC in each group, and no differences across all patient groups...

The National Comprehensive Cancer Network (NCCN) guidelines recommend completion thyroidectomy for patients with multifocal papillary thyroid carcinoma (PTC) diagnosed by paraffin pathology after lobectomy. However, studies for the influence of surgical range on prognosis of unilateral multifocal carcinoma are scarce. We analyzed the clinicopathological characteristics and long-term outcomes of patients with unilateral multifocal PTC to identify risk factors for recurrence and disease-related death.The clinical and pathological data of 123 cases with multifocal lesions in the unilateral thyroid lobe were retrospectively collected, including sex, age, stage, surgical range, histopathology characteristics, and follow-up data...

CONTEXT: The Hippo signal transduction pathway is highly conserved in mammals. It plays a critical role in tissue and organ size by regulating the balance between cell proliferation and apoptosis. However, there have been few reports concerning Yes-activated protein-1 (YAP-1) elevation in papillary thyroid cancer (PTC). OBJECTIVE: The objective of this study was to determine whether YAP-1 expression is a biomarker and high-risk clinicopathologic prognosticator in PTC...

Backgound. The follicular variant (FV) is one of the most common variants of papillary thyroid carcinoma (PTC). Clinically, the FVPTC is considered a low-risk variant of PTC, and the encapsulated forms of FVPTC represent a group of thyroid tumours with an overall good prognosis. Consequently, these neoplasms were very recently reclassified as "non-invasive follicular tumour with papillary-like nuclear features (NIFTP)". From a molecular standpoint, NIFTP appears similar to the follicular pattern thyroid neoplasm; however, limited data are currently available regarding their gene expression profile...

REVIEW
Lawrence A Shirley, Natalie B Jones, John E Phay
Papillary thyroid cancer (PTC) is the most common thyroid malignancy, and cervical nodal metastases are frequent at presentation. The most common site for nodal metastases from PTC is the central compartment of the ipsilateral neck in the paratracheal and pretracheal regions. The decision to resect these lymph nodes at the time of thyroidectomy often depends on if nodes with suspected malignancy can be identified preoperatively. If nodal spread to the central neck nodes is known, then the consensus is to remove all nodes in this area...
