OBJECTIVE: There is debate whether hemithyroidectomy is sufficient for patients with papillary thyroid cancer (PTC) sized 1-4 cm. Therefore, we investigated whether hemithyroidectomy affects recurrence rate compared with thyroidectomy in patients with PTC sized 1-4 cm. DESIGN: Retrospective observational study. PATIENTS: We included 147 patients with 1-4 cm PTC who underwent hemithyroidectomy between 2004 and 2008. They were matched with 298 patients who underwent thyroidectomy, comparing age, sex, tumor size, multiplicity, and extrathyroidal extension status, and lymph node (LN) metastasis status...

BACKGROUND: Despite the new technical alternative offered by the robotic surgery for minimally invasive thyroid surgery, the role of the robotic thyroidectomy (RT) in thyroid cancer has been highly disputed. This paper gives a systematic review and meta-analysis aiming to compare RT and open thyroidectomy (OT) based on the surgical outcomes and oncologic results. METHODS: Relevant literature was searched from various databases up to July 2016, including PubMed, MEDLINE, EMBASE, Cochrane Library, Web of science and Clinical Trials...

INTRODUCTION: Increased body mass index (BMI) is known to be associated with the high prevalence of Differentiated Thyroid Cancers (DTC); however data on its impact on survival outcome after thyroidectomy and adjuvant therapy is scanty. OBJECTIVE: We aimed to evaluate the impact of BMI on overall survival (OS) and disease free survival (DFS) rates in patients with DTC. METHODS: Between 2000 and 2011, 209 patients with DTC (papillary, follicular, hurthle cell) were treated with thyroidectomy followed by adjuvant radioactive iodine-131 (RAI) therapy and thyroid-stimulating hormone (TSH) suppression...

Context: Currently, no recurrence or mortality risk systems consider molecular testing when predicting thyroid cancer outcomes. Objective: We developed an integrative prognostic system that incorporates TERT promoter mutations into the recently proposed risk reclassification system after initial therapy (dynamic risk stratification, DRS) to better categorize and predict outcomes. Design: A total of 357 differentiated thyroid cancer patients without initial distant metastasis were enrolled...

The aim of this systematic review is to study the features of cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) by analysing the 129 documented cases in the English literature. The disease occurred almost exclusively in women. The median age of presentation for CMV-PTC was 24 years. Slightly over half of the patients with CMV-PTC had familial adenomatous polyposis (FAP). CMV-PTC presented before the colonic manifestations in approximately half of the patients with FAP. Patients with FAP often have multifocal tumours in the thyroid...

OBJECTIVE: Metastatic lymph node ratio (MLNR) is a known significant predictor of disease-free survival in differentiated thyroid cancer. The authors investigated the ability of preoperative fluorine-18 fluorodeoxyglucose (F-FDG) PET/CT to predict recurrence after surgery with radioactive iodine therapy considering MLNR. PATIENTS AND METHODS: A total of 274 patients who underwent preoperative PET/CT and surgery with radioactive iodine therapy were enrolled. The tumor-to-liver uptake ratio on PET/CT was calculated by dividing the maximum standardized uptake value of a primary lesion by the mean standardized uptake value of the normal liver...

Papillary thyroid cancer (PTC) is the most common tumor subtype of thyroid cancer. However, not all PTCs are responsive to current surgical and radioiodine treatment. The well-established clinical prognostic factors include tumor size, lymph node/distal metastasis, and extrathyroidal invasion. The RET/PTC-RAS-BRAF linear molecular signaling cascade is known to mediate PTC pathogenesis. However, whether presence of BRAF mutation, the most common genetic alteration in PTC, can affect PTC behavior and prognosis is controversial...

PURPOSE: The lymph node ratio (LNR) is an important prognostic factor in papillary thyroid carcinoma (PTC), but micrometastases in cervical lymph nodes (LNs) are not of great clinical importance. In this study, we analyzed the accuracy of prediction of the prognosis depending on whether micrometastases were included in the number of metastatic LNs when calculating LNR. METHODS: The study included 353 PTC patients who underwent total thyroidectomy with neck LN dissection, and calculated LNR by 2 methods according to whether micrometastases were included in the number of metastatic LNs: Method 1 did not and method 2 did include...

REVIEW

It is worthwhile to measure serum thyroglobulin (TG) level in thyroid cancer before subjecting patients to surgery for two reasons. Firstly, if the level is high, it may give a clue to the local and metastatic tumour burden at presentation; secondly, if the level is normal, it identifies the patients who are unlikely to show rising TG levels in the presence of thyroid cancer. Those who have high serum TG before surgery will show up recurrence as rising serum TG during the postoperative period. Those who do not have high serum TG before surgery will not show up rising serum TG in the presence of recurrent disease...

OBJECTIVE: The objective of the study was to evaluate the safety and effectiveness of three-dimensional (3D) endoscopy for thyroidectomy and compare it to two-dimensional (2D) endoscopy. The major limitations of conventional endoscopy include its lack of depth perception and tactile feedback. The 3D endoscopy technique, which involves 3D imaging, is widely used. However, few reports have described the use of 3D endoscopic systems in thyroid surgery. METHOD: In this single-institutional study, 103 consecutive patients who underwent endoscopic thyroidectomy between July 2013 and April 2014 were enrolled...

The term noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was recently proposed to replace noninvasive follicular variant of papillary thyroid carcinoma (FVPTC) both to promote more conservative management of these tumors and spare patients the psychological burden of a cancer diagnosis. This reclassification will lower the incidence of papillary thyroid carcinoma (PTC). In addition, it could result in an increase in the rates of unfavorable histologic prognosticators for PTC overall because NIFTPs had previously accounted for many of the PTCs without these features...

BACKGROUND: Serum thyroglobulin (Tg) is the key parameter used in the follow-up of subjects with differentiated thyroid cancer (DTC). Current guidelines advise its measurement to take place when Thyrotropin (TSH) levels are >30 µU/ml (stimulated Tg) and when TSH < 0.1 µU/ml (suppressed Tg). Although stimulated Tg levels <1 ng/ml have been shown to display excellent prognosis, relapses may occur despite low Tg levels. Recently, very low cut-off levels of stimulated Tg have been proposed for determining the recurrence risk in these subjects...

OBJECTIVE: The invasiveness of papillary thyroid carcinoma (PTC), including the occurrence of cervical lymph node metastasis, is the main determining factors contributing to recurrence and poor prognosis. Laminin 332 is a glycoprotein involved in cell migration and cancer cell invasion into surrounding tissues and is therefore related to poor prognosis in many cancers. Here, we investigated the expression and role of laminin 332 in PTC and examine the possibility that laminin 332 could be involved in the invasiveness of PTC...

BACKGROUND: Recurrence of papillary thyroid cancer is not uncommon, but incorporating clinicopathologic parameters to predict recurrence is suboptimal. The aim of this study was to identify systemically recurrence-associated genes using The Cancer Genome Atlas RNA sequencing database. METHODS: A total of 504 patients with transcriptome sequencing data of the primary neoplasm were included in this study. High and low levels of expression of each gene were defined by median splits...

Anaplastic thyroid cancer (ATC) is a highly malignant disease with very short median survival times. Few studies have addressed the underlying somatic mutations, and the genomic landscape of ATC thus remains largely unknown. In the present study, we have ascertained copy number aberrations, gene fusions, gene expression patterns, and mutations in early-passage cells from ten newly established ATC cell lines using single nucleotide polymorphism (SNP) array analysis, RNA-sequencing and whole exome sequencing...

The purpose of this study was to assess the relationship between vitamin D receptor (VDR) mRNA expression and prognosis in papillary thyroid cancer. RNA sequencing and somatic mutation data from TCGA (the Cancer Genome Atlas) were analyzed. VDR mRNA expression was compared to clinicopathologic variables by linear regression. Tree-based classification was applied to find VDR cutoff and patients were split into low and high VDR group. Logistic regression, Kaplan-Meier analysis, differentially expressed gene (DEG) test, and pathway analysis were performed to assess differences between groups...

BACKGROUND: Ewing sarcoma survivors (ESSs) are at increased risk for treatment-related complications. The incidence of treatment-related morbidity and late mortality with aging is unknown. METHODS: This study reports survival probabilities, estimated with the Kaplan-Meier method, and the cumulative incidence of cause-specific mortality and chronic conditions among ESSs in the Childhood Cancer Survivor Study who were treated between 1970 and 1986. Piecewise exponential models were used to estimate relative rates (RRs) and 95% confidence intervals (CIs) for these outcomes...

The prognostic role of molecular markers in papillary thyroid carcinoma (PTC) is a matter of ongoing debate. The aim of our study is to investigate the impact of RAS, BRAF, TERT promoter mutations and RET/PTC rearrangements on prognosis of PTC patients. We performed a search in four electronic databases: PubMed, Scopus, Web of Science and Virtual Health Library (VHL). Data of hazard ratio (HR) and its 95% confidence interval (CI) for Disease-specific survival (DSS) and Disease-free survival (DFS) were directly obtained from original papers or indirectly estimated from Kaplan Meier curve (KMC)...

BACKGROUND: The incidences of both thyroid cancer and breast cancer have been rising in recent years; however, it is very rare to find a single person with both of these cancers. Only a few cases of synchronous thyroid and breast cancer have been published, and even fewer cases have been reported in older patients (>60 years). CASE SUMMARY: The current study presents a case of synchronous papillary thyroid carcinoma and breast ductal carcinoma in an elderly patient...
